Hevc x265 vs h265 reddit. unRaid, Tdarr, Sonarr, Radarr, and Plex user here.

Hevc x265 vs h265 reddit You will get about 10-15% smaller files for the same if not better quality. They are just the software that creates video in h26x format. My existing processor has a passmark of 1688 and I'm getting about 50% of real-time transcoding. As a result so many people and trackers looked down on H265 encodes for a long time. Since updating my file renaming options, I've noticed that x265 encoded videos are getting either "HEVC" or "x265", while videos encoded in x264 seem to consistently only have "x264" in the filename. t0paz, pof, pahe, ivy megusta These are great stats. Trackers with 1080p h265 web-dl and x265 focus 1080p h264 WEB-DL vs 1080p h265 WEB-DL H264 takes up more space to no appreciable benefit. You'll need a way to convert the h265 into MPEG2 (the format of DVDs. However last I benched it, AVC and HEVC encode right around the same performance on Ampere/30 Series. x265 (the open source encoder used by the community) isn’t as good (yet!) as the professional reference encoder. Decoding can be done on a single core CPU, but for a decent experience you'll want quad core or better. I have "HEVC" "x265" "x. I don't know how its quality is. Here's a set or SSIM tests done on Prores vs h. Use ProRes, DNXHR, GoProCineform for editing. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app. 265. If you're doing a ton of editing with the footage, you might not have a smooth experience with H265 depending on what you're doing with it and on what hardware. 264 file with a bitrate 25-50% higher than HEVC when YouTube used the AVC codec. SVT-AV1 at low bitrates produces worse artifacts than x265. Experienced encoders don't care and just use whatever that suits their boat because well, it doesn't really matter much other than speed. AOMedia Video 1 (AV1) is an open, royalty-free video coding format initially designed for video transmissions over the Internet. In the literal big picture, a 50% avg bitrate loss on HEVC encode is usually unnoticeable to most in terms of quality, and most TVs today add some level of post processing to make up that difference, though some are bad at it. The long answer is that x265 behaves VERY differently than x264. x265 is used widely in production. This is also true of H264 but moreso with H265/HEVC. 265 (x265): 197MB (took 20 min 1 sec to encode) hello, im now having a problem, i want to encode some Blu-ray as well but im stuck between 2 qualities 1080p Blu-ray x265 HEVC AAC 8 bit and 1080p Blu-ray x265 HEVC AAC 10 bit. How is x265's file size so much smaller and has so much lower bit rate than NVENC? EDIT: I understood the trade-offs between size/quality regarding x265 vs NVENC, and knew NVENC was going to produce a bigger file. In addition to what shmushkan said, note that only the latest GPUs have full hardware acceleration for H. If both machines aren't h265 capable there is no point in trying to force it. H. In which case transcoding could kind of defeat the purpose but proxies are always an option. I just went by the x265 documentation/Handbrake recommendations. 265 compression if my NAS' processor is only a 6 year N3060 dual celeron 1. HEVC is h265 which is not the same as x265. e. On the other hand, AV1, Opus codecs and MKV, WEBM containers are completely free and open source. On a pixel level, yes there is loss in detail. Look at it this way: Higher efficiency in x265 means that a 1GB x265 will look better than a 1GB x264 video. Most people seem to prefer h. Is this the usual target or is it higher than normal? I mean, hevc/x265 encoded anime like the ones by judas or reaktor look quite good despite being like 1/5th the size. As for HEVC, that comes in the form of H265 or x265. It's the price you pay for excellent compression though. But really HEVC has been out for years and is the transition technology on the road to the new AVC-1 / AV-1 codec. 90% of what downloads is x265. Thought it was bad wifi signal, so bought a CC Ultra second hand, as that thing doesn't seem to be sold anymore. For example, HEVC(x265) is motion based, meaning that it saves space by monitoring stationary pixels. I think it really depends on your needs. I don’t have the exact numbers from my AV1 vs. Ideally I’d like high quality h265 at the smallest file size. If you move it down to 720p, you can move the CRF up to 17-18. x265. It offers substantial improvements over H. HEVC is not and will likely never be a standard on the web, for example, while AV1 already. Hi, I want to convert a bunch of 4K h264 videos to h265. 44gb with 28. H265 has to be transcoded to H264. i would download the x264 because its size is larger, but i'm confused because of the 10bit/8bit stuff. You can also use NVENC 10-bit through like Staxrip and it goes a little faster. x265 is an open source, free implementation that conforms to the h265 standard mentioned above. x264 and x265 are not codecs, they're libraries used to encode to a codec (h264 or h265). h. x265 Low Quality: siq 6CH. Ya your CQ for 265 is way, way to high. Plus the x264 copy doesnt include any featurettes, the x265 copy might. It means if you choose h265 preset slow CRF18 it's not the same quality than h265 preset medium CRF18. 265 is the standard (the "rules" of the format), x265 is a software encoder that conforms to those rules. The higher the quality of your original video the less advantage h265 make. 265 (HEVC) is an amazing codec. I tend to do a software x265 test encode of a chapter, and match the filesize with the equivalent compression values using hardware h265 vtb … the resulting filesize is same or smaller, but I can encode dvd at up to 700fps! … The myth of "HEVC can halve the size of AVC encodes" has led to a swarm of very bad H265 micro encodes that lack enough bitrate and were full of artifacts. 266/VVC is better at all bitrates but is way harder to encode and decode. 265 vs. Let's switch to more modern codecs: Welcome X265/HEVC X265/HEVC, Slow, 6Mbps, 2 passes. Problem solved. NVENC is nvidia’s encoder which can only encode h264. They're completely different algorithms and right now, I think x265 generally produces a more consistent picture quality. As I understand it, HEVC/h265/x265 cannot be streamed using mpeg-ts. Quality difference side-by-side wasn't noticeable to me. For my usage, I don't do production. 8GB file. For x264 web-rips, I don't bother re-encoding them. x265 10-bit veryslow vs slower vs slow I made the mistake of encoding my whole library with x264 10-bit, so now I need to re-encode all of it. HEVC gives you better quality at lower bitrates. VP9 and HEVC are similar in efficiency, with HEVC taking the lead in higher-fidelity video. So a 2gb movie at x265 is much better quality than 2gb x264 movie. I have a Ryzen 5900x and I still get roughly 2fps on the x265 10-bit veryslow preset and 3. I’m having great trouble choosing the best settings. Realistically HEVC offers roughly a 30% improvement over AVC, so a ~5gb x265 movie is probably comparable to an 8gb x264 encode of the same movie, even moreso if the latter was just done on defaults. HEVC has gained quite the traction in the past few years and there are very many good releases. AV1 is the new emmerging standard but from the review i've read; AV1 is only better at 1900bps or lower. 264 is more widely compatible than H. Others say there's no difference at all. tldr: go with the smallest size h265 or h264 that passes your eye test; choose h265 over h264 if your client can handle playing it without overheating, hanging or crashing My understanding is that (all other things being equal) it will cost you 4x the file size to get the same quality in h264 as h265. What?! Slow X265 is faster then x264 and quality is the same. If there is a lot of movement in a scene (action or sci-fi) then it might look a bit weird if one group of pixels doesn't move with the rest of I've run a few test encodes with HB 1. 265 (AKA HEVC) standard. NVenc is a hardware encoder (uses dedicated encoding hardware on GPU), and is designed mostly for screen recording/streaming, and so speed is its main objective. Select 60 as the frame rate. Well, honestly, I don't think I've ever noticed any quality loss with H264 at all. so it takes shortcuts and requires a higher bitrate to store the same quality image as x265. You will need to make sure that you either A have a more powerful playback device or B have a playback device with a dedicated HW decoder. (yep, i know that it was different preset, but still) Ok, let's give it more bandwidth: X265/HEVC, Slow, 8Mbps, 2 passes. If you're asking whether b-frames will help with color banding, it depends upon the complexity of the scene--but any help they'd offer would be minimal. Does anyone have suggestions for which groups I have done tests on this in the past (which annoyingly were made defunct when YouTube transcoded everything to VP9 a week later!) I found that h. I can't remember if it was the PS5 or Apple something that doesn't adhere to the MKV spec properly so some MKVs have to be transcoded remuxed into MP4 but that's not a heavy task in most cases. H265 is nearly the same file size and visually superior in every way and in a 5th the time to boot. 84gb with 27. efficiency. Google searching tells me also RTMP is not an option. I do 8k 3D VR180 and I usually use H265 NVidia MAIN10 because it's 10-bit. Over time, MAME (originally stood for Multiple Arcade Machine Emulator) absorbed the sister-project MESS (Multi Emulator Super System), so MAME now documents a wide variety of (mostly vintage) computers, video game consoles and calculators, in addition to the arcade video games that were its AV1 vs H265 . HEVC test. This is another huge bonus. The default is P6, the mediation is high quality, the multi-encoding is 1/4, and the main configuration is The rest can refer to NVIDIA's recommended settings: Does 720p have better detail being encoded in x265? Or would 1080p x264 be better in terms of detail/granularity? I know I would need to look into the other factors like bit rate and fps etc but for now just trying to find out which option I should be trying to go for. The file sizes and encoding times of the encoded videos were: using H. The one caveat is HDR which is x265 Main 10. 5 hours HEVC). But after checking about media servers like Jellyfin and emby, I was pretty impressed. Jul 30, 2022 · H. 3MB vs 45. My situation: I'm trying to decide between using HEVC 10-bit or traditional x264 for video playback on my Galaxy S10 considering storage capacity is not a problem, but battery life is. Sep 13, 2024 · If you are wondering what value this provides, HEVC encoding offers a better quality video at the same bit rate, allowing for a higher quality video over the same bandwidth usage for streaming from your Plex Media Server! Additionally, this encoding preserves HDR metadata, w Dec 3, 2024 · H. No, in 8 bit x265 vs 10 bit x265, the 10-bit outperforms 8-bit by a small amount. People use H265 as gpu encoding and X265 is cpu encoding instead of writing it all out h265 = ( Nvenc HEVC , Nvenc x265) There's like 5 different ways to write the same thing and it differs on each program . I tried the following two custom presets to encode a sample 60FPS HDR, 4K Video. x264 actually picks out more grain, and x265 is a much smoother codec. I have performed multiple encode tests targeting an average bitrate and the relative filesize is almost always the same between H265 intel QSV and x265. HEVC scales better with higher resolution. Remuxes are usually x265, because why not. Being jellyfin free and easy to install, it was my first option. But the size difference is a lot the 8 bit is about 113gb but the 10bit is about 160 gb H. It is not reencoded compared to the bluray, its the same thing but as an mkv. 1mb/s bitrate). x265 is a program used to encode to h265. x265 10-bit is a bit better though if you’re looking for compression and smaller file size. Typically 4k footage is h265. If it is H264, it must be at least 12000. If I am re-encoding from a TV rip/BD Rip, I usually use HEVC now since most hardware supports it now. 265 AMD-VCE: 679MB (took 2 min 48 sec to encode) using H. Which is better as output when I've been doing a lot of experimentation with h. g. All of my regular Plex client devices direct play except for a Chromecast Gen 2 I have dangling off the back of an ancient DLP. They are faster, meaning they have decent Real-time encoding performance. 0MB vs 30. To calculate, 15 years ago was 2008. Interframe vs Infraframe codecs: “There are intraframe and interframe codecs. HEVC/x265/h. 265/HEVC by distributors. So there is no way of comparing as X264 and X265 are cpu encoding NVENC and AMD-VCE gpu encoding. "Hardware Support Here's a quick rundown of well-known hardware that includes dedicated HEVC decoding blocks, which definitely support efficient HEVC playback: H265 is fine for any player on the same local network as the client. 26* vs x. SVT at its best is better than x265, but at its worst, it's much worse. 265 can be hard on old HW to decode on the fly so run some test footage through your main device first. I find that at higher bitrate it's even worse than x264 fast at preserving dark gradients. But it is tangentially related with context and a linked article and my compilation project should anyone care to easily and quickly catch up to all Tigole's releases (that I know of). BluRay. Because I had problems at first with the above plugin I also tried one, which uses handbrake to transcode ("Tdarr_Plugin_s7x9_winsome_h265_10bit"). Wrong. 264 is AVC and H. As for CQ value, the default for x265 is 28, so start at that and work my way down in numbers. QXR makes larger size encodes using HEVC. H265 is most often used with 4K releases as it is a common codec for source files of that size to lower the storage space required. Create a new tag, new release profile, set up preferred words (x265, hevc, etc. H264 to H265 will show some differences, but they usually are minimal (in my experience) 2 - too many variables to say, but it will take time. Even most smart TVs have built in hardware H265 decoders right now based on that I've seen since they can do direct play H265 plex content with no transcoding Once most devices have AV1, I'll totally jump on board Almost no 1080p content is encoded in H. 265 (High Efficiency Video Coding or HEVC) is the successor to H. Files produced via x265 are HEVC, but not all HEVC/H. HEVC is more efficient (Can provide same quality at lower bitrates, generally speaking) and this efficiency comes at a cost of performance on software/CPU. HEVC was a standard at that time. My Mi Box S can even do HEVC 4K natively. So x265 is software that encodes video to the H. Even if it matched H265 the time trade off isn't Question: I did some close up comparisons of the videos, and the quality of the x265 file is pretty comparable to what NVENC produced. 8 (it's technically still 30, haha) for all Hollywood made movies. If something is labeled as x265 is it encoded. HEVC in itself is supposed to provide almost minimal loss of quality while reducing the size drastically. But a ~2gb x265 Joybell release is gonna look way worse than an ~8gb x264 FGT copy. 6. 264 for 1080p content, and stick to 4K remuxes. So as a general rule, stick to H. That being said, if you can’t use HEVC for some reason, but have the ability to use vp9, use it! It’s dramatically better than x264 in most cases. Switching to HEVC x265, would allow me to have far better streaming quality, as the file size is far smaller at a higer resolution and bitrates. Encoders have opposite have also opposite behaviour, as x265 gets more efficient at producing quality when inceasing 'compression', meanwhile NvEnc gets less efficient. I've made extensive comparisons with my personal tuning for x265 last year (default tunings for x265/HEVC encoders are not really that good for preserving fine detail) and found out that AV1 washes away more fine low contrast detail than x265 at resonably bitrate levels (which is something difficult to quantify, but equivalent to around CRF 22 This is purely anedoctal but I was just testing H265 10bit vs H265 with NVENC on my 3070 and the file size for a two hour movie was around 2GB larger with NVENC but it did complete about 3x faster than H265 10bit. 265 are both fine BUT, they come in a Ton of flavors. The files do not have HDR. nearly fifteen years old: If you upgrade your GPU and CPU, it is no longer 15 years old. I was purposely hunting for high banding shots to test differences and came across this case which is more about clarity and detail. So I use the default 28 on iPhone recordings i've taken, and I bump it up to 30. Vvc vs av1 is Google open source vs paid mpeg proprietary codec vvc (h266). Vp9 is not. 265), and at a given file size, a non-terrible software encoder (x265) will generally look batter than almost any hardware encoder (the fixed function encoding hardware in your nvidia GPU). Just curious what people think about Blu-ray content compressed by x264 vs the same content compressed by NVENC H265 on an Ampere or Turing card like the RTX 20/30 for example. Given most devices that run Chrome have a HW HEVC decoder, but most don't have an AV1, HEVC is really the best codec to use in browsers too, now. 265 when uploaded at equivalent bitrates, i. 264 vs h. Every article i find on the web about transcoding with Tdarr are for the HEVC format. SOME shows gets H264 for like a day, then will auto replace with a 265 as they get re-encoded. Mint/FFmpeg/Shutter Encoder. Some say theres a huge quality loss converting h264 to h265. ) are more quality focused and the slower will increase quality and file size. But there's some optimizations that you can make to grab as much grain as possible using x265. If you're shooting on a GoPro, ProRes is overkill. Ive found it to be a good sweet spot. First thing, we can see that x265, despite being significantly slower, is far to be ridiculous, with x2. Try to use H265 and AVI as the live broadcast bit rate. 265 (HEVC) looks a little nicer (less blockiness in dark areas) but also causes stutter on some systems. That was wiered. H265/HEVC is a video codec. Qualcomm (the second-biggest holder of HEVC patents) is trying hard to support HEVC and avoid supporting AV1 because they want those sweet, sweet HEVC royalties. There is no proof that at high bitrates x265 easily outperforms x264. So no, a 1. I find this advice does NOT apply to x265 encoding. X265 default is 28, and they recommend +/- 2 given personal taste. The AV1 file size was about 8% less than HEVC. I have every episode of the office ripped from makemkv taking a ton of space up. Also known as HEVC. I tried HEVC 10-bit x265 slow at RF 23, no filters, and got a 12GB file. Start with the Fast 720p preset. 264 vs H265, mp4 vs mkv? Help Am I right to store/play my videos in H. Feel free to prove me wrong but from what I've seen and been told it doesn't. 9fps on slower. H265 NVENC vs. X264 and x265 are the cpu encoders for h264 and h265 respectively. Just how different they look depends on quite a lot, including: The actual file size / target bitrate Svelte is a radical new approach to building user interfaces. H265 by nature is designed for streaming (the likes of Netflix, Disney+ and such) so the lower the bitrate the better the encoder actually becomes compared to H264. nVidia before 9th gen has none, 9th & 10th gen only do 4:2:0 and only the 16/20/30 series Depends on the encoder implementation. Mostly. Basically its taking say 1080 and making it look very close to 720 and taking forever to do it. HEVC/x265 does well as low bitrates, where there is huge quality loss except for things like anime. You can have a better quality with a preset slow CRF20 than a veryfast CRF18 for example (I didn't test these values it's just for the explanation). I remember AV1 being substantially slower at processing (6 hours AV1 vs 1. I'm having trouble wrapping my head around the RF vs. 264, developed by the Joint Collaborative Team on Video Coding (JCT-VC). However, from what I understood HEVC and VP9 are very similar in terms of performance (VP9 a bit weaker than HVEC), but VP9 is way more supported by web browser, according to this image When transcoding with ffmpeg the file size shrinks to between 1/2 and 1/3 of the original (using the plugin "Tdarr_Plugin_075a_FFMPEG_HEVC_Generic"). x265 at lower bit-rates is certainly more significant and will offer the best picture quality. Intraframe means that the compression is done within the frame itself. I understand the HEVC is the best format in terms of retaining quality but how big of a drop is x265 HEVC/H. H265 is the codec, X265 is your processor’s encoder which can only encode h265. H265 (don't wanna say "can't" be, but currently isn't able to be) transcoded on the fly. the "x265" ones, generally when it starts with x, means it's the software encoding based encoder, using your CPU to render. In fact, your CPU also has an inbuilt HEVC decoder which makes a big difference. 265 (x265)", and all other settings remained the same. I guess its because YouTube uses Googles own codec which is VP9. 8MB RF 18 very slow vs RF 16 fast>> 67. There was a time I grabbed 1080p x265 in just about 200mb but I understood the meaning of quality after seeing quality encodes. I am running the most recent Kodi (Aura skin) on Windows 10. HEVC compresses better. Just remember that you're compressing to reduce file size and reach transparency in normal viewing -- pixel peeping at still images of in-motion scenes is NOT how people normally watch movies. I know this was pretty strait forward with x264 but I've read many times that x265 presets (fast, med, slow, etc. mkv It depends on how much you notice. Typically you'll want to match quality or file size to get a reasonable point of comparison. 264 in terms of compression, enabling higher-quality video at lower bitrates. The normal H265 takes way too much time so I'd rather avoid that. HEVC files play file in any other player. RF 22 very slow vs RF 20 fast >> 30. So I wouldn't expect your problems to have been solved by simply changing the encoder. Only YOU can decide what CQ number looks ok to your eyes. 10 bit almost eliminated all color banding issues NVEnc had with H265 Reply reply shiris H265 is much more complex than H264 and so is very heavy on the CPU. There is also nvenc encoders for h264 or h265 that uses Nvidia gpus. As for x264 vs x265, these are software projects that are fairly widely used in programs like FFmpeg or HandBrake. So 4k is 4 times as big a resolution Sep 27, 2024 · x265 is an encoder, so there no such thing as "x265 nvenc". ) u/Kichigai has exactly what you need - the ability to convert the h265 via FFMPEG. Also, just because you have gear that can deal with H265 doesn't mean you can still shell out for HDD whenever you're low on space. Or check it out in the app stores h265 main VS h265 main10 . It will likely be in h264 or h265 for the codec. It provides good efficiency. WEBRip. As u/spong_miester Only Kodi has this issue playing only HEVC (x265) files. It seems like there's better MP4 support overall. 265" "h265" and "MeGusta" as 4 separate terms in my sonarr profile search. Some of it has already been encoded with h264 rf 20, but I have h265 hardware decoding on both the server and client, so I figured, why not encode them with hevc as well. unRaid, Tdarr, Sonarr, Radarr, and Plex user here. Some recommend only transcoding 4k content or BR remux's to h265. They are usually encoded optimised for streaming already, and I don't want to loose any more quality doing a second re-encoding on them. And at lower bitrates, the fidelity is pretty much indistinguishable. The code rate value is recommended to be 10000. The ~8gb x264 and the ~5gb x265 will look pretty close. (AMD) or (NVENC) or (QSV) are hardware encoders built into your GPU. I'm tempted by that 10-bit to remove the color banding I rarely ever see anyway, but meh my perfectionism still tempts me. Replacing H264 for H265 saves a ton of space even at 1080p. For the couple of 4K rips I have done, x265 10-bit CRF26 has been fine. i want to download a movie that has 2 options: x265 10bit (29. There is just no advantage to be had here. Remuxes of 1080p blurays are either MPEG-2, VC-1 or H264. I'm trying AV1 level 5 (which is a lot slower). I have been experimenting to find the best possible way through handbrake. I'm more familiar with x264 than x265, but I've always seen the description that CRF is a quality slider and the options enabled by different presets allow lower bitrates at those qualities Reply reply Its not a miracle, its not a panacea, but real world you can expect a well encoded ~5-7gb x265 copy to be comparable in quality to an ~8-10gb AVC copy. It was developed as a successor to VP9 by the Alliance for Open Media (AOMedia), a consortium founded in 2015 that includes semiconductor firms, video on demand providers, video content producers, software development companies and web browser vendors. The x265/H265 software encoders automatically incorporate b-frames into their presets, or you can tweak them using advanced options. 26*). So 4k hevc has better compression than 720p hevc. Something labeled as HEVC or h265 usually means it is not encoded, but a raw remux or webdl. x265 (release titles), with negated required exclusions of ALL x265 groups, listed out 1 by 1. Not that I'm aware of, I've uploaded in H265 and it doesn't work for me also I spoke to their partner support / forums and they said they don't support HEVC H265 and don't plan on. It wasn't that long ago that x264 outperformed x265 at high bitrates! It has improved since then, but not that much. And the point of x265 was that you get the same quality at around half the bitrate compared to x264, so there's a lot of bandwidth and disk space savings. 265 is HEVC, so ideally avoid mixing terminology by saying "H. The result is fair, but knowing that HEVC would result in much better quality at the given upload speed limit, I would prefer to stream using the x265 codec. If you mean H265 NVENC then yes, it will be worse than x265 with reasonable settings. 3mb/s bitrate) vs x264 (30. 264 instead of H. But HEVC is pretty well-supported on certain hardware devices like phones. I'll try to explain it as simply as possible. Move the encoder preset as slow as you can tolerate (try a few short test encodes to see how it goes, generally each step is half the speed). The best way to get both lower bitrates at the best quality is to run veryslow conversions and tune your RF setting to what you like. There are definitely test clips where vp9 scores higher on metrics but generally x265 does better from what I’ve seen. r/AV1 is available on https://lemmy. x265 10 bits is the best actually (2022)! Vastly superior than x264 and x265 8 bits, way more compatible than in the past (Youtube, Facebook, everybody accept those nowadays, most new players too) and the extra color space give you so much power on night and low light level scenes. HEVC MP4/MKV is better quality at the same bitrate as an AVC MP4/MKV. x264 and x265 are the encoders (that's the difference between h. For MOST content I'm not interested in h265 4k, it does not increase my immersion enough to be worth the storage premium. Yes. 265 decode. This advice works for either x264 or x265. H265 has more benefit encoding at higher resolutions (4k and above) and requires both the host (encode side) and client (decode side) machines to be h265 capable. Similarly, the x264 software encodes video to H. (edit: user dragonwhoosh has provided links now) The key thing is just to understand what efficiency means, and what it means for one codec to beat another. General advice in this sub is slower encodes make smaller files. At least for me it doesn't work, where h264 works flawlessly. While you would get slightly longer recording times at those bitrates, it wouldn't be significantly longer. Both have good compression rates, h265 being the better of the 2, but the caveat is that transcoding h265 is a bit more CPU intensive than h264, so your media server, Plex/Emby/Jellyfin/etc will get hammered slightly harder w/ h265 files. This is absolute bollocks. I’ve been experimenting exporting using software x264 x265 encodes constant fr at quality 18-22 and the same with hardware (videotoolbox) encodes for 264 & 265. x265 is usually used with re-encoding H265/H264 source files to a much smaller size while maintaining a good amount of visual quality through the use of filters I then changed the video encoder to "H. There's not usually much mention of 1080p x265, only 4k x265 or 1080p x264. I want to make a tier list similar to Trash's tier list (WEB 01, 02, 03, bluray 01, 02, 03, etc) but specifically targeted for x265 release groups. I think NVENC or Intel Quick Sync H265 is the way to go if you want fast encodes. . There are many different factors in hevc too, and it all depends on the encoder. At least around 1500kbit/sec with 2-pass/3-pass (AV1 uses 3 pass). MAME is a multi-purpose emulation framework it's purpose is to preserve decades of software history. Even with an i9 10980XE, encoding a 2 hour 4K video takes a day at a time on CPU at the slow preset. 264 and H. The latter had a video bitrate of around 2000 kbps. 265 offer high quality per bit than x264. So how do you guys stream HEVC/x265/h265 with ffmpeg? Small terminology note, H. Very old hardware can't process x265 to the point that it is irrelevant. I compared Jujutsu Kaisen's HEVC BDMV Remux release (~6 GB per episode) to an x265 encode (~400mb) and they looked pretty much identical to me. IN a perfect world, you'd use an FFMPEG tool - maybe with a User interface (vs. there is a difference. 265 is the encoder. HEVC". Devices that don't support HDR likely don't support this particular variant of x265 even if they claim x265 support. Just based on personal tests i'm still leaning that x265 is producing a higher quality output with 'Slow' preset and aq-mode=3 vs something like Preset 4 AV1 with equal bitrates. If you've ever tried to use ffmpeg to convert to/from various formats you will understand the frustration. 265, not on the features of x264 vs x265. If you encode a video to both H264 and H265 using settings that produce similar results, the h265 file should be smaller. Preset stuff when it comes to quality and file size with HEVC/x265. H265 10-bit for 1080p(/i) Blu Rays Best settings to encode a 4k HDR x265 10-bit . 265, and once my research has finished I'm gonna actually publish a paper and I will post it all over reddit so that people can read the paper and see what the various settings will give them and so forth. with the h. 4MB RF 20 very slow vs RF 18 fast >> 45. What gets confusing is that you could encode an 8bit file to h265 and in theory it should play well so if there is no standard in encoding and file naming, it leaves the door open to "is that h265 (HEVC) file real 10bit or is it just 8bit in the wrong format?" I encode specifically to 8bit HEVC since 10bit HEVC serves no purpose for what I encode. and thats Nvenc H265. which one should look better? thx Considering the h265 file is less than half the size, it is undoubtably a better compression and on 90% of shots, RF18 looks the same on both. h264 vs h265 format, future ? Hi, I wonder what is the best codec for archival between h264 or h265, which codec will be easily readable by devices in 10 or 20 years ? I find it hard to discount x265 though, as the space savings are very impressive for very little quality drop (3GB vs 600MB for a single TV episode). Over the next year or two the GPUs will go from hardware decoding AV1 to also encoding. It depends. It all depends on what quality is acceptable to you, if a HEVC version looks acceptable to you, then go for it. H264 (x264) is still far superior to H265 (x265) at high bitrates, H265 is designed as a streaming codec, not an archival one. 264 is a very widely supported standard that's been around a long time. world/c/av1 due to changes in Reddit Within a given compression format (e. 8MB Maybe there is a tiny quality difference I don't see, so the better quality must be with the slower encode, regardless of RF value, right? A ~5gb x265 encode from Silence or Afm72 or somebody is going to look way better than a ~2gb x264 RARBG or YTS encode. You can upload prores mov's (at least on YouTube) if you absolutely want the highest quality and don't care about file size. But I did try to work something out for you: In terms of speed at default settings: NVENC > x264 > x265 Just like h264 vs vp8 and h265 (hevc) vs vp9. But the bitrate of the H265 NVEnc video is lower than the 264 one. The choice between them should be based on h. AV1. ) as required, apply release profile to tag, apply tag to shows, Sonarr will only grab files with the required words. But then require x265 with 4k content Why would that be? Does x265 mean more loss of quality with lower resolutions ? Why should you not do x265 with say 1080p content ? My understanding was that x265 was just better overall to preserve more quality with less size, and that the only reason to use x264 was for device compatibility. 4MB vs 67. X265 CPU - Whats the current state of play? Hi all, whats the current general opinion/state of play when it comes to H265 encoding, especially for 4K video. Get the Reddit app Scan this QR code to download the app now H. 5 to 5 slower speeds. Switching to H265 NVEnc is twice faster, and the file size is about 1/3 smaller. But, realistically your biggest impact on quality is going be your Topaz settings. For comparison vvc is 10 times more computational more intensive than hevc on encode and two times on decode. H265 is a codec, its a type of compression. That being said, release groups usually encode their HEVCs at lower bitrates than their AVCs (small size RARBG 1080p x264 VS small size RARBG 1080p x265, for example). The quality between the two seems comparable. Bought a CC third gen some time ago, noticed it couldn't handle high resolution movies from my plex server. HEVC was not a standard 15 years ago. It's actual software. I have Indiana Jones and the Last Crusade in 4K, a MakeMKV rip. Almost nothing had HEVC hardware decoding/encoding. H264 > HEVC > VP9 > AV1 For Quality to Size Efficiency: AV1 > VP9 > HEVC > H264 For lower bitrates, VP9 is worse than HEVC but still slower. AV1 is likely going to end up being slightly behind HEVC in raw performance That's only the current hardware encoded AV1 that is just behind software encoded x265 with archival settings (but much faster to encode and no Ip issues). 1 - No, unless you start with the source (bluray/etc) and encode directly from it. a command line) such as WinFF Just tested it and the quality is real close to x265 fast preset. He/she/it does 4K and RM4K and 1080p and everything always in HEVC x265. 264 vs. 265 is a newer codec which can reduce your bandwidth requirements for a given quality by around a quarter to a third, for most videos. GPU transcoding. 264. 265" or "AVC vs. 4ghz? I’m getting very good results from Videotoolbox on M1 iMac. However, it also depends on resolution. CPU had better quality vs. Now for the CRF 18 it's just an indicator of the quality for the SAME settings. You set x265 to a very high quality metric at the expense of a ton of storage. Its not quite a transparent encode, the full remux will still be slightly better, but a 5gb HEVC copy will look better than Netflix usually at least. There are other implementations that are NOT free and must be licensed like the ones used on Blu-Ray discs. Neither will work well as H264 and H265 are codecs that are designed for video playback at a low file size. HEVC (High Efficiency Video Coding) is just another name for the H265 standard. You can even skip the tag steps if you want it to apply to all shows by default. If you want to switch to VP9 or AV1, then a good reason would be because you want to play it back through a web browser, or because you don't want to support the software patent mafia. I've heard a lot of conflicting information about what file and quality profiles should be downloaded to h265/hevc. It's supposed to be a replacement for the "old", but widely supported and used H264. 265 are video codecs for compressing image frames to video. I KNOW it will take extra time to encode these rips, but it will save space. x265 and professional paid software HEVC encoders trash nvenc hevc for example and the reference aomenc trashes the nvenc av1 Help needed understanding which encoding/presets: [nvenc vs h264 vs h265] for 4k source Hi all, tldr: Please help me pick a good strategy for 4k resolution that doesnt take days. But if you connect remotely, and need to reduce the quality for smoother playback, your server is gonna work harder. But this is not free of cost. Tons of "older" hardware (like 5 years old) can do H265. AV1 software decode can impact battery life on long-form content, And is a lot more likely to drop frames in higher resolutions on less powerful devices. Once that happens AV1 will become “real”. H264 is more widely compatible with players, h265 is newer and allows for similar video quality with lower bitrates. 264 and h. At high bitrates the difference becomes little to non existant. The ONLY significant difference is time, with the intel cutting down the time by half to more. My settings for DVD rips are the following: x265 encode CF 20 Medium speed (448kbps AC3 passthru audio) This results in a ~180mb 22 minute episode. By that measurement I'm guessing either the i5 or i7 would fit my needs, as they are both well over double the existing. I build a ryzen 3950X system just to do my transcodes. In this case the x265 means the person reencoded the remux, lowering the quality, in order to make it h265 and lower the size. HEVC-PSA (done as release title, not release group as I think PSA has some lower quality releases also) elite 1080p. No my comment is not directly about the difference in quality. Get the Reddit app Scan this QR code to download the app now. x265, 1080p. 4GB x264 video will not look the same as a 700mb x265 video, x265 will look worse. My primary playback devices for rendered content is an Nvidia shield, which doesn’t support AV1 hardware decode. HEVC (x265) is better in all regards except as people have said it requires modern hardware. 264 gets better quality than h. I have tried streaming Naruto Shippuden and Wonder Woman 1984, both in 1080p x265. x265 17RF is the same as AV1 25RF for constant quality, assuming all other settings the same, and speed set to medium (x265) and 5 (AV1) No and it's not even close. less stutter but still couldn't render 4K streams. But using it on Android devices and Android TV with HEVC x265 rips, its a hit or miss all the time. Firstly, whenever you re-encode something, it will always have some drawback; that's just how it is. AV1 will by far take the longest, but it will give you a much smaller file size. 6/2. Then adjust the RF target up a few points at a time until you find the quality vs size tradeoff that best suits your preference. I think that x265 is the sweet spot. 264 because of the smoother performance but if you really hate the compression artifacts you could try HEVC instead. I though encoding to x265 was much more slower and difficult than x264 so how do reaktor and judas and other mini encoders put out so many anime at such good quality? Chrome added HEVC decoder passthrough in the fall. 265 files are created with x265. The bitrate you need to get equivalent quality from HEVC to ProRes is fairly similar. Not sure why X265 behave like this, will better preset If you’ve got something that’ll do it, your best bet would be to convert the source to ProRes (even bigger) run it through Topaz, export ProRes from Topaz, then run Handbrake once to convert the 4K ProRes to HEVC (x265). Not sure about Intel/ARM but a quick Google will usually turn up a spec sheet. I can't find the usually mentioned test that people link to with this. All will give the same video quality. If 10bit h264 or 10bit h265 makes a difference in Instagram, its maybe because the h265 video had a higher quality in general, so the transcoding turned out better. H265 isn't supported on ancient hardware. AV1 SVT 10-bit at the same RF and level six got me a 20. You can also use svt with preset 4 or 5 and be much more efficient than x265. The x265 project is based on the x264 code so they're very similar to one another, though obviously they implement different encoding. 264 vs HEVC at different bitrates. I’m using an M1 iMac 24” and am stunned by the speed. H264 and H265 are the video codecs for the video track. gcpxft ebpox ekkg vpham dmlpdo kcv ayndnm yuujkh fqras araaz
