I want a setting that I can use on any incoming 4K HDR video I buy. Not the answer you're looking for? I believe that the last value of 31.6 Mbps is exceeding the capacity of the Chromecast v2. Libvorbis for audio seems slow. Do people usually encode with 20+ for 1080p? The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. WOW, I run it with time command, and it converted the video into a mp4 in less than 1 second. Thanks for contributing an answer to Stack Overflow! Of course, these metrics aren't perfect but you can use them as a rough guide to establish equivalence. Dealing with hard questions during a software developer interview. Applications of super-mathematics to non-super mathematics. FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. Just copy my settings and youre done!You can view the \"Step By Step\" instructions on The Webernets Website - https://www.thewebernets.com/2021/02/06/quick-easy-best-optimal-settings-for-handbrake-convert-dvd-video-to-h-265-hevc-mac-windows-linux/Lots of interesting information on the H.265 Codec here - https://x265.readthedocs.io/en/3.1/index.html You can change this by adding -b:v option to ffmpeg. Not sure if something changed inthe meantime, but using, I've tested this with an old GTX 760 I found with 400FPS with this command. https://gist.github.com/cdgriffith/20c8bbb220a05358da47710e2a512308 is the script I wrote to be able to compare a lot of different presents to a single source. Anything from 18-40 could give a very decent quality level. FFmpeg commands I using are the following: I used 30 as CRF for testing purposes because the artifacts are more visible :). Asking for help, clarification, or responding to other answers. Connect and share knowledge within a single location that is structured and easy to search. In our case it is 3840px width.

Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. (if you go higher than 4.1 preset). I use both as .bat files. Connect and share knowledge within a single location that is structured and easy to search. Suspicious referee report, are "suggested citations" from a paper mill? For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). This topic can be confusing, so it's important to learn the difference. . 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. Encode some random segments from typical inputs. I have to use a separate comments for every statement. If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. )Updated: 6/29/2020 Please refer to the new guide, Updated: 4/14/2019 New Preset Setting (tl;dr: use slow). Hmm interesting, may i ask why this scales doesn't correspond? Why does Jesus turn to the Father to forgive in Luke 23:34? 28 and 23 are the default CRF values of x265 and x264 respectively, hence the supposed equivalence. I know from some small scale testing that the gaps between the different presents will remain similar (newer article has better graph for that). Why using b-frames does not reduce the size of my video (using ffmpeg and nvenc)? So lets take a step back and look at the lowest 1% of the frames. For example, with constant bit-rate encoding, you can specify -rc:v cbr (which is significantly faster than the cbr_ld_hq rate control method, bringing an additional ~20% boost to throughput). How to make PNG video render into 10bit h.264 matroska/avi file? I wanted to thank you for all this great work youve done on these articles. Slower = better video quality and compression. rev2023.3.1.43269. Every modern browser on desktop and mobile supports it, except Safari on iOS. Transcoding FLV toMP4 with ffmpeg very slow, FFMPEG resize video not working in browser or IOS. The open-source game engine youve been waiting for: Godot (Ep. I use the monochrome12 profile. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. I started with a 4K HDR example video. They claim that a 4K video coming into their site should optimally be 35~45Mbps when encoded with the older x264 codecs. Profiles can be set via the -profile:v option, similar to libx264. (This will generate a logfile that ffmpeg needs for the second pass. In this case, you are using two different encoders, so you get different bitrates. Choose the highest CRF value that provides an acceptable quality. Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. Predictable file sizes are a priority. In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. Does With(NoLock) help with query performance? Start by understanding the encoder's options. It states that for 4K videos with x265 they suggest a Constant Rate Factor (CRF) encoding in the range of 22-28 (the larger the number the lower the quality). Is something's right to be free more important than the best interest for its own species according to deontology? Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. So what *is* the Latin word for chocolate? Super User is a question and answer site for computer enthusiasts and power users. The slow preset was used as it was determined to be an ideal choice in previous tests. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. The only point of using x265 is for compatibility, lossless and HDR content, otherwise, even at SDR 4k x264 will fare better if given enough bitrate. 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. Between H.264 and H.265, from what I've read the difference is about 30%, which is an impressive improvement at that point, considering how efficient H.264 already was, but from a practical standpoint it's too small to justify a systematic conversion just for the sake of saving a few gigabytes (or even hundreds of gigabytes - you may end up If you are encoding to x264 or x265, encode to 10-bit if your devices support it. (As a heads up h.265 is the specification, and x265 is encoder for it. Asking for help, clarification, or responding to other answers. Thanks for contributing an answer to Stack Overflow! If the same information really answers both questions, then one question (usually the newer one) should be closed as a duplicate of the other. Is email scraping still a thing for spammers. thank you, I'll try it now and feedback you later ^^, I use it to decrease scale. Would the reflected sun's radiation melt ice in LEO? PTIJ Should we be afraid of Artificial Intelligence? 22 medium 65.979806 0.959182. I'm using my FFMPEG with the suport of my GPU (NVENC) to convert files from my satelite receiver (SD, mpeg2 .TS-Files) into h264 .mp4-files. Why did the Soviets not shoot down US spy satellites during the Cold War? This is also all evolving, so next year the AV1 tools may be fast and user friendly enough to use that instead of H.265 for encoding. rev2023.3.1.43269. Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. Using AVIF and HEIF images with Python / PIL, https://gist.github.com/cdgriffith/20c8bbb220a05358da47710e2a512308, https://github.com/Netflix/vmaf/tree/master/model, https://i0.wp.com/codecalamity.com/wp-content/uploads/2019/04/4K_preset_avg_extra.png?ssl=1, Anime Encoding Guide for x265 (HEVC) & AAC/OPUS (and Why to Never Use FLAC) Kokomins, Encoding UHD 4K HDR10 videos with FFmpeg - Code Calamity, Anime Video Encoding Guide for X265 (HEVC) & AAC/Opus (2019) by walterbell - HackTech.news, Hardware Encoding 4K HDR10 Videos? Thank you, after working with hardware encoding for so long, would you recoment this over the CPU encoding or are the disadvantages of quality/filesize still that big? The absolute path to the output file. Getting ffmpeg with libx265 support ffmpeg needs to be built with the --enable-gpl --enable-libx265 configuration flags and requires x265 to be installed on your system. Choose the slowest preset that you have patience for. Find centralized, trusted content and collaborate around the technologies you use most. So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. Afterwards compared them to the original using the Structural Similarity Index (SSIM). Thank you!! 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. Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions.

CEO at Pixel Point and software engineer with 10+ years of web development experience. So lets get a little more apples to apples. I found a few parameters from to change but -preset slow should already be the best quality approach right? A few interesting options for us are: libvpx-vp9 - which is used be default when you convert to WebM using VP9 codec, libx265 - for H265 code and mp4 container, hevc_videotoolbox - for H265 with a hardware acceleration. https://www.youtube.com/watch?v=bzgFL-gNF9g. Video and audio streams inside these containers are multimedia data encoded with codec. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? Note that when using faster presets with the same target bitrate, the resulting quality will be lower and vice-versa. Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. What would be the most time effective format and how to convert a raw h.265 video to it? By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. There is only one time to not use it. I used a three minute 4K HDR clip, using Handbrake to only modify which present was used. The best answers are voted up and rise to the top, Not the answer you're looking for? Your inputs are already H.265/HEVC, so you can simply mux them into MP4 without needing to re-encode. Video Production Stack Exchange is a question and answer site for engineers, producers, editors, and enthusiasts spanning the fields of video, and media creation. And since you're on Windows, you may want to remove the shell escapes \ above as I'm writing this from a Unix box testing the command above. rev2023.3.1.43269. To make your file compatible with Apple "industry standard" H.265 you have to add the following argument -tag:v hvc1. Maybe my setup isn't the best: I'm using ffmpeg for transcoding and vlc for review the videos, then i copy the screen content and compare the screens on a program like photoshop. Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. Then I recently read YouTubes suggest guidelines for bitrates. I have a raw footage and the quality of details of h264 with same CRF setting looks better than h265. Modern web development every year applies new standards for performance. Reddit and its partners use cookies and similar technologies to provide you with a better experience. The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. Unfortunately, the same can't be said about videos. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. 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. Jordan's line about intimate parties in The Great Gatsby? For more information, please see our Maybe my setup isn't the best: I'm using ffmpeg for transcoding and vlc for review the videos, then i copy the screen content and compare the screens on a program like photoshop. I personally think the extra 2500kbps for the large jump in minimum quality from CRF 24 to CRF 22 is a must. FFmpeg supports hardware accelerated decoding and encoding via the hwaccel cuda, h264_cuvid, hevc_cuvid and h264_nvenc, hevc_nvenc modules. For two-pass, you need to run ffmpeg twice, with almost the same settings, except for: For libx265, the -pass option (that you would use for libx264) is not applicable. It enables constant quality mode, which guarantees a certain perceptual quality level within the entire video by passing a number from 0-63(VP9) and 0-51(H265), where 0 is the best quality and the maximum number is the worst. It only takes a minute to sign up. This is best explained with an example. 3 seconds at the start is nothing as long as the movie plays fine. Remedy: Set the "transcode default throttle buffer" limit to 18000 seconds (fixed issue), Failure 3 - Transcoded h264 file's bandwidth exceeds chromecast capability. 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. 1. (d). By using CRF 15~18 vslow, Film TUNE, and 5.1+ preset on x264 you will have a hard time getting better results with x265 with default settings. The Compilation Guides show you how to do that. Something wrong with reddit clipboard. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Is this enough, or should I take some other things into consideration as well? Even though others have tackled this issue, I wanted to use the same material I was already testing and make sure it held true with 4K HDR video. Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! Not the answer you're looking for? You can list private options available in this encoder with ffmpeg -h encoder=libx265. Press J to jump to the feed. @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. You can also download a static build, all of which bundle libx265. 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. Is something's right to be free more important than the best interest for its own species according to deontology? What looks good today may not look so good in the future on a new display. As always, start by specifying a preset. 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. Should have been already almost completed in all its parts! Also that I always recommend crf over hard bitrate/filesize because it is really source dependent for saving the proper amount of quality. By default, this is disabled, and it is generally not required to set a tune option. ac3 should give you a 15%+ boost in speed. It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? The jump from medium to slow is very significant in multiple ways. Call up the binary. 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 ? Open a 2nd command line and encode another .ts at the same time. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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). Maybe something more visible at lower bitrates? What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? Well well wishing well, that is even more definitive. Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (360p.m3u 8) has not been used for any stream. Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? Could the loss of quality be caused by VLC and its experimental support in deconding h265? Download the SSIM data as CSV. 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. Also, I raised a flag to mark it as duplicate. Linking VCEEncC in the Settings panel of FastFlix is the easiest way to get started with it and will automatically put the required setting of --output-depth 10 to make it 10 bit. Asking for help, clarification, or responding to other answers. The webm was quite small, but take many times the amount of time that mp4 took. (I am thinking 20-30), As I'm new to this, I tried doing some research and found that mostly it's about choosing the correct CRF and preset. Get a stunning-looking website made by in-house team of motion, graphic, and web designers. Ive specified it to 3x the 8Mbps (so 21M). Not bad, but we can do better! 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. Do you think for H.265 but with 1080p and less content that all of what youve posted here would still be applicable or do you think its only for 4k content? The bitrates are as expected, the higher quality it gets the more bitrate it will need. If we run the command above, it compresses the video down to 542 KB. Why are non-Western countries siding with China in the UN? . Whereas FFmpeg can deduce the required output format of a file depending on the selected extension of the output file, it is recommended to explicitly declare the output format (through the -f option) so that extra options can be passed to the underlying muxer if needed, as is often the case with streaming formats such as HLS, mpegts and DASH. (And if I ran these tests first, I would have even used slow for all the other testing!). To some, including myself, it could be worth the extra 4000kbps jump from CRF 22 to CRF 20. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. There are two most popular tools for video optimization -Handbrake andffmpeg. Adding -crf 0 is not required. You're still doing high bitrate encoding. Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). Those other encoders might be better - I haven't studied that PDF closely. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? https://i0.wp.com/codecalamity.com/wp-content/uploads/2019/04/4K_preset_avg_extra.png?ssl=1 why there is CRF 16 and CRF 17 dot showing? Here we can see x264 has a much harder time at lower bitrates. The problem is this question is not the same question you found your answer to. For everyone else, you can follow instruction on the site. 1 When I transcode video to H265 with following command, I get a bitrate about 600K and the quality is almost the same as the original. There's a TLDR at the end. ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc. The original was H.265 encoded with a .ts extension. If we wanted to go by YouTubes recommendations for a video file that will be re-encoded again, you would only need a 25Mbps x265 file instead of a 35Mbps x264 video. An addition to the previous comment. (b). When you omit this option, ffmpeg uses -crf 32 for VP9 by default.
