It only takes a minute to sign up. Well, the size was the same (7,7MB, instead of the 3,8MB using the ffmpeg -i without any other option), but it was fast. I've gone through this sub and tried to improve my transcodes, but I'm still not 100% there. But they either increase the encoding time significantly or require more tries to find the best bitrate setting to achieve similar results that you can do with Constant Quality (crf) mode. Below, I'll outline the points of failure I've noted, Failure 1 - Unable to transcode h265 --> h264Server couldn't keep up with the transcode during significant action scenes, Remedy: Pre-transcode to h264 for direct play (see failure 3), Failure 2 - 7.1 AAC transcodes to 7.1 EAC3 - playback stops when transcoder hits the 'throttle' limit. Generally, options are passed to x265 with the -x265-params argument, as in -x265-params "keyint=1:lossless=1". Was Galileo expecting to see so many stars? I tried H.265 10 bit, H.265 12 bit, and H.264 10 bit, and they all ended up looking washed out compared to the original file. So, if generally the CRF of h265 are "better" qualitatively speaking than the x264 ones how is possible that the encode results of x265 is worst than x264 with same CRF ? Of course, these metrics aren't perfect but you can use them as a rough guide to establish equivalence. And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. Choose a CRF. Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. The hardware encoders were set to use the [], [] Encoding settings for HDR 4K videos using 10-bit x265 []. When it comes to bitrates, ensure that your desired values are set via the -b:v, -maxrate:v and -bufsize:v options. This is most useful for workloads such as live streaming where broader compatibility with a wider variety of devices is expected, and as such, performance crippling features such as B-frames can be omitted altogether for a good trade-off between higher bit-rates in use and throughput. It is well known between pros that SSIM and PSNR are not good measures or SUBJECTIVELY PERCEIVABLE quality. The Main profile is capable of 8-bit, Main 10-bit is capable of 10-bit, and Range Extended is capable of more than 10-bit. Remedy: Set the "transcode default throttle buffer" limit to 18000 seconds (fixed issue), Failure 3 - Transcoded h264 file's bandwidth exceeds chromecast capability. Maybe something more visible at lower bitrates? Aka a old movie with lots of film grain will need a lot higher bitrate than a modern action / adventure move, which will itself needs a lot higher than an animation. Use the -x265-params lossless=1 option. Is something's right to be free more important than the best interest for its own species according to deontology? You can remove this scale=858:482: from my scripts. You can list private options available in this encoder with ffmpeg -h encoder=libx265. The webm was quite small, but take many times the amount of time that mp4 took. Encode some random segments from typical inputs. Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee. There is no such thing as "proper bitrate". It makes your video web-optimized and results in faster video readiness. Also note that the highest marker on this chart is 0.98, compared the total average charts 0.995. Could the loss of quality be caused by VLC and its experimental support in deconding h265? To learn more, see our tips on writing great answers. Thanks for contributing an answer to Video Production Stack Exchange! Not bad, but we can do better! In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. Hope that helps, thanks for asking and happy to help! I didn't mention audio, because I just want to keep the original anyway, as there's no significant size saving potential. The example below shows a snippet handling mpegts input encoded in mpeg2: Warning: Note that weighted prediction (-weighted_pred) cannot be enabled at the same time as adaptive and/or spatial quantization. Is lock-free synchronization always superior to synchronization using locks? When comparing to standard 4.1 profile than yes, x265 outperform it in almost any metric. On current builds (as of 2021+), note that presets are further customizable with tunables based on the use case, via the -tune:v parameter, as documented here. Is this enough, or should I take some other things into consideration as well? A home for professional coders articles, opinions and ideas. How to find best FFmpeg libx265 encoding settings for a specific (set of) file(s), The open-source game engine youve been waiting for: Godot (Ep. Asking for help, clarification, or responding to other answers. Find centralized, trusted content and collaborate around the technologies you use most. I use both as .bat files. If it doesnt have HDR, the time to encode it doesnt make sense to me as it will take over twice as long vs H.264. We have some hard date, lets use it. You canread thisdoc for more info on this. Download the SSIM data as CSV. Would the reflected sun's radiation melt ice in LEO? Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). Now this is an apples to oranges comparison. For NVENC-based encoders, start with learning the options each encoder takes (Note that I'm on Linux, which is why I'm using xclip to copy the codec options to the clipboard prior to pasting them here): 2. Connect and share knowledge within a single location that is structured and easy to search. Keep in mind that is while still being lesser quality than CRF 18 - Slow. The one advantage of hevc_videotoolbox over libx265 is that it supports encoding videos in H265 with alpha channel. If libx265 is too slow use libx264 which is faster but file size will be bigger. I ran some quick tests this morning with a script I am using for a new version of this article using ffmpeg instead of Handbrake. What are some tools or methods I can purchase to trace a water leak? I will make a few tests with h264. @llogan. TLDR: FFMPEG transcode 1080p h265/HEVC 7.1 5Mbps--> h264 12Mbps (31.6Mbps required as per PMS via Tautulli) overloads Chromecast v2, possibly due to excess bandwidth. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? rev2023.3.1.43269. Code Calamity 2023. Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git The default is 28, and it should visually correspond to libx264 video at CRF 23, but result in about half the file size. Apple brought WebM support since macOS Big Sur to Safari on desktops, but to this day failed to make any progress on its mobile version. An addition to the previous comment. See a list of available x265 profiles. is there a chinese version of ex. Why did the Soviets not shoot down US spy satellites during the Cold War? How can the mass of an unstable composite particle become complex? (d). However, there is still a solution. Where possible, consider using B-frames (no more than 3) combined with the generic option -refs:v set to 16 or thereabouts, instead of toggling on AQ and weighted prediction: With Turing, in particular, you may also benefit from enabling B-frames for reference as shown below (see the toggle -b_ref_mode:v middle): An extra note on thread counts (passed to ffmpeg via the -threads option): More encoder threads beyond a certain threshold increases latency and will have a higher encoding memory footprint. Why did the Soviets not shoot down US spy satellites during the Cold War? 28 and 23 are the default CRF values of x265 and x264 respectively, hence the supposed equivalence. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Because if every frame was that good, we shouldnt need more than 6Mbps x265 or 10Mbps x264 4K video. Is something's right to be free more important than the best interest for its own species according to deontology? Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! You can verify lossless encoding by looking for x265 [info]: lossless compression ratio in the console output from your encoding command, or refer to the hash demuxer for verification. I did three CRF videos first, at 22, 20, and 18, then using their resulting bitrates created three ABR videos. Dont be sad though, there is a solid alternative for iOS users. ffmpeg -i input.h265 -c copy -movflags +faststart output.mp4 The camera's H.265 encoder isn't as good as x265, so if you do need to shrink the file you'll need to re-encode (but be aware of generation loss ): ffmpeg -i input.h265 -c:v libx265 -crf 28 -preset medium -movflags +faststart output.mp4 Adjust -crf and -preset to your liking. Even if your source video doesnt use the HDR color space, it compresses better. Handbrake has a GUI, and it makes it much easier to use; however, using ffmpeg is a more flexible option in case you want to render videos with alpha(transparent) channels or use hardware acceleration that speeds up compression a lot. Not the answer you're looking for? Setting up NVENC (for Streaming) Modern OBS Studio has two ways to achieve the expected quality: the built-in NVENC H.264 (new) and the addition from StreamFX called NVIDIA NVENC H.264/AVC (via FFmpeg). Encode new files to MP4 or MKV. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? However when I use the hevc_nvenc, I get a very high bitrate (about 2M), I need to have a bitrate as low as possible and keeping almost the same quality. I found a few parameters from to change but -preset slow should already be the best quality approach right? There is currently a serious lack of data on compressing 4K HDR videos out there, so I took it upon myself to get learned in the ways of the x265 encoding world. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Is this the best possible solution, or is there a better way of doing this? What are the best settings for me to use when encoding x265 videos? Does Cosmic Background radiation transmit heat? I guess this solves my problem. So lets get a little more apples to apples. So lets take a step back and look at the lowest 1% of the frames. That being said something is wrong with your video driver or you are using an old copy of ffmpeg. FFmpeg commands I using are the following: I used 30 as CRF for testing purposes because the artifacts are more visible :). TLDR: FFMPEG transcode 1080p h265/HEVC 7.1 5Mbps--> h264 12Mbps (31.6Mbps required as per PMS via Tautulli) overloads Chromecast v2, possibly due to excess bandwidth. For everyone else, you can follow instruction on the site. See FFmpeg Wiki: H.264 for more info. Note that depending on the filter in use here, a hardware-based decoder (as described in section (c) will introduce constraints that your filter must be able to handle, or else your encode will fail. ), In pass 1, you can leave audio out by specifying, P. Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. Try running ffprobe on it ( ffprobe -i filename.ts -show_streams ) to see what the format and colorspace are, for HDR should be: pix_fmt=yuv420p10le color_space=bt2020nc color_transfer=smpte2084 color_primaries=bt2020, (Windows ffmpeg/ffprobe package https://ffmpeg.zeranoe.com/builds/, others https://ffmpeg.org/download.html), Found this incredibly helpful, as Ive recently begun ripping Blurays to x265 instead of x264, particularly when I got my new 12-core Ryzen 3900X. [] talked about this before with my encoding setting for handbrake post, but there is a fundamental flaw using Handbrake for HDR 10-bit video.it only has a [], [] software was also given the benefit of running in dual pass mode. Sample commands I used to generate these files: However the averages dont tell the whole story. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? I dont use x265 for anything besides 4k HDR content. Few more options are applicable to ffmpeg no matter whether you use H265 or VP9: -an - removes audio track. Therefore I played it safe, bump it down a notch and just encode all of my stuff with x265 10-bit at CRF of 20 on Slow preset. Learn more about Stack Overflow the company, and our products. Scroll down to the bottom to see notes on the performance impact of presets with this particular encoder. . Through some experimentation I found that I personally never can really see a difference between anything lower than 22 using a Slow present. Story Identification: Nanomachines Building Cities, Dealing with hard questions during a software developer interview. Now, if I have a super computer and unlimited storage, I might lean towards CRF 18 or maybe even 16, but still wouldnt feel the need to take it the whole way to CRF 14 and veryslow or anything crazy. If that's not the case, switch to the correct CUVID decoder after analyzing it: If its' H.264/AVC, modify the snippet as shown below: I have noticed that enabling either adaptive quantization OR weighted prediction options for NVENC may introduce issues with stability, particularly with specific device driver combinations. Press question mark to learn the rest of the keyboard shortcuts. Connect and share knowledge within a single location that is structured and easy to search. Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. What is the potential range for a good CRF value? As a bonus you can use the following nice shell script below that can create for you optimized video in VP9 and H265 with a single command. I started with a 4K HDR example video. In this test, I encoded all videos with ffmpeg using the default presents. They have some good detail on what things mean. Then, using that information, proceed to the next step. Now I know that x265 can be around 50% more efficient than x264, and that YouTube needs it higher quality coming in so when they re-compress it it will still look good. 22 medium 65.979806 0.959182. The difference between the input and the output is practically non-visible for 1080p videos. Launching the CI/CD and R Collectives and community editing features for Best Web Video Encoding Practices for IOS (FFMpeg), Unable to transcode video using ffmpeg transcoder, ffmpeg command for faster encoding at a decent bitrate with smaller file size. Create an account to follow your favorite communities and start taking part in conversations. The slow preset was used as it was determined to be an ideal choice in previous tests. Also, I raised a flag to mark it as duplicate. as in example? Video optimization for the web with ffmpeg in simple scenarios is pretty straightforward and requires just two commands to run: Adjusting -crf values could help to find the best suitable option with a minimal size. Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. The number of distinct words in a sentence.

If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? My experience with using nvenc is that you need to tell it what bitrate you want -- it defaults to VBR, which is fine, but no amount of tuning makes up for the fact that it always wants to give you a 2M average bitrate no matter what resolution file you feed it. I use the monochrome12 profile. explicitly disabled interlaced encoding on Turing, github.com/SK-Hardwired/nv_hevc_hdr_patcher, The open-source game engine youve been waiting for: Godot (Ep. Handbrake 1.2.2. For WebM, it's VP8 and VP9, while in mp4 could be almost anything. Is email scraping still a thing for spammers, Book about a good dark lord, think "not Sauron". How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? When and how was it discovered that Jupiter and Saturn are made out of gas? @Dr.Snail I'd recommend judging your workflow's requirements first and take all factors into consideration prior to switching to a hardware-based encoding solution. For this, you can use -c:v flag. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. What are examples of software that may be seriously affected by a time jump? Making statements based on opinion; back them up with references or personal experience. The short answer to the deviation from expected performance is that x265 is still under "heavy development". The Compilation Guides show you how to do that. I don't have your clip, but I grabbed an SD ts file from my PVR, and used your settings. This should work in your command line. The Compilation Guides show you how to do that. Connect and share knowledge within a single location that is structured and easy to search. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. What CRF or settings I should choose for h265 in order to achieve a similiar quality of h264? Note: Windows users should use NUL instead of /dev/null and ^ instead of \. How can I recognize one? Use this mode if you want to retain good visual quality and don't care about the exact bitrate or filesize of the encoded file. shouldnt slower preset produce better picture quality? Use CRF 23+ for videos in 4K. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? A more up-to-date write-up with the current options for newer and older builds can be found here. (As a heads up h.265 is the specification, and x265 is encoder for it. This is a simple easy guide on how to make the best DVD conversions to H.265 encodes with the smallest file size in Handbrake without having to know or understand all of the settings. For the llhp and llhq presets, as well as other presets in use, you can also override the in-built rate-control methods by passing the -rc:v arguments as exposed by the encoder options. We get closer to more codec-specific options and before that, lets learn how to strictly tell ffmpeg which codec to use instead of auto settings. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. So lets take a step back and look at the lowest 1% of the frames. Thanks for contributing an answer to Stack Overflow! PTIJ Should we be afraid of Artificial Intelligence? 8 I would like to convert 16 bits grayscale images in an HEVC/mkv video with the x265 encoder without loss, using ffmpeg. - Code Calamity, Animated AVIF is finally coming to Firefox, AMD improves video encoding yet again! What would be the most time effective format and how to convert a raw h.265 video to it? Not the answer you're looking for? H265, a.k.a HEVC (High-Efficiency Video Coding), is a codec supported by Apple and shows the same 20-50% better efficiency than its H264 older brother. As with CRF, choose the slowest -preset you can tolerate, and optionally apply a -tune setting. Making statements based on opinion; back them up with references or personal experience. Server: MacBook Pro with 2.66GHz i7, 4GB DDR3Connection to router: 5GHz WiFiMonitored with Tautulli (PlexPy), Chromecast v2 --> Onkyo Receiver 7.1 setup --> 1080p Sony Projector, Chromecast v1 --> Yamaha Receiver 5.1 setup --> 1080p TV, Amazon Firestick --> Yamaha Receiver 5.1 setup --> 1080p TV, These are connected over 2.4 GHz, unfortunately, (I know, I'm running some seriously old components in heresome are a decade old. Replies: 2 Last Post: 20th Jul 2015, 11:17. It is not a royalty-free codec - perhaps, that is why the adoption rate is much less than of WebM's. Still, we get a good idea of where these show up. x265 uses CRF 18 by default. We haven't used it in VP9 WebM because its architecture does not require this and always guarantees progressive loading. Does With(NoLock) help with query performance? (e). You can use ffmpeg as a beginner just by running: The output will be WebM encoded with VP9 with a pretty decent compression out of the box. In this case, you are using two different encoders, so you get different bitrates. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Call up the binary. (c). x265 CRF 28 is supposed to be equivalent to x264 CRF 23. I want a setting that I can use on any incoming 4K HDR video I buy. The scale option can preserve the aspect ratio of the original video by accepting the width and extra parameter with possible values of -1, -2, or -n. -2 value guarantees that the resulted output resolution will be even. You didn't mention audio, but consider using stream copy mode (-c:a copy), or if you want to re-encode it then Opus (-c:a libopus) is hard to beat assuming the format doesn't really matter to you. That said, you can try to establish your own calibration between the current versions of the encoding libraries in your ffmpeg by running the following command, which executes two popular video quality metrics: The final lines of the console output will contain: So, run the command once with the x264 output and once with x265 and compare with different x265 outputs, till you get similar measures. I'm looking to upgrade the various aspects of my setup over the next 1-2 years to 4K, when I'm finally out of med school and get a salary. By Edgewall Software By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. is it worth to spend more time to encode slower preset? YouTubes suggest guidelines for bitrates. Great explanation. Additionally to the previously mentioned arguments, ffmpeg VP9 and H265 codecs accept -crf flag . You can indicate this by, i can link the answer to the other question. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. So, I'll link to the other answer that I posted. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. Their overall average SSIM scores were near as identical. See HWAccelIntro for information on supported hardware H.265/HEVC encoders. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. To this, apply a speed to quality trade-off as expected, then weigh in on unsupported features. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Adding -crf 0 is not required. ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc. It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. compression.ru/video/codec_comparison/hevc_2015/. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? 1. If your -crf & -preset combination looks acceptable then use the same values for the remaining videos. This is why the duplicate flag has been declined. It's therefore wise to limit thread counts on encodes where latency matters, as the perceived encoder throughput increase offsets any advantages it may bring in the long term. WebM is an open, royalty-free media file format designed for the web. I got 700fps (Yours settings) on a GTX750 (non TI) (the cheaper one), I got 925fps (Your settings with ac3 audio), Answered here: The most widespread scenario for this one is scale. Best settings for converting from h264 to hevc? (g). Thanks for contributing an answer to Stack Overflow! Start by understanding the encoder's options. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? It looks to take about a crf increase of 2 to achieve near parity of medium to slow (aka 18 medium is close to 20 slow). Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
