Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. (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. Asking for help, clarification, or responding to other answers. We haven't used it in VP9 WebM because its architecture does not require this and always guarantees progressive loading. how to use FFMPEG to transcode h264 to h265 on Ubuntu 12.04? See FFmpeg Wiki: H.265 for more info. Modern video codecs can deliver excellent quality while preserving a very reasonable size. ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless. Afterwards compared them to the original using the Structural Similarity Index (SSIM). Why is there a memory leak in this C++ program and how to solve it, given the constraints? Making statements based on opinion; back them up with references or personal experience. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? The difference between the input and the output is practically non-visible for 1080p 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? ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc. )Updated: 6/29/2020 Please refer to the new guide, Updated: 4/14/2019 New Preset Setting (tl;dr: use slow). 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 this enough, or should I take some other things into consideration as well? However, CRF shows its true edge on the lowest 1%, easily beating out ABR at every turn. 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. 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. Code Calamity 2023. CEO at Pixel Point and software engineer with 10+ years of web development experience. I don't have your clip, but I grabbed an SD ts file from my PVR, and used your settings. Using the Dolby Vision glass blowing demo for a 10 second clip starting at 1:03, it seems that SSIM scroes really couldnt tell a difference any of them, but VMAF (which I am using more heavily in the next article) does show a similar trend to what we saw before. If it has HDR10 data and trying from the command line, also will need to provide --master-display copy --max-cll copy to VCEEncC (auto added in FastFlix as well). Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? (f). What are the best settings for me to use when encoding x265 videos? So lets take a step back and look at the lowest 1% of the frames. Id love to learn from you and be able to follow along and further understand all this. Best settings for converting from h264 to hevc? However, I head that this cap was removed. Adding -crf 0 is not required. Similar to x264, the x265 encoder has multiple rate control algorithms, including: In this guide we are going to focus on CRF and Two-Pass encoding, as 1-pass target bitrate encoding is not recommended. Yes, @Dr.Snail. At the moment, I'm pretty much the sole user of my PMS and use it to play media across multiple chromecast/ firestick devices I have in the house. compression.ru/video/codec_comparison/hevc_2015/. See a list of available x265 profiles. The absolute path to the output file. Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? This will be very fast as it is "copying and pasting" the H.265 video into the MP4 container: 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): Adjust -crf and -preset to your liking. To learn more, see our tips on writing great answers. 1. It only takes a minute to sign up. Should the results be the same, relatively? I use the monochrome12 profile. To some, including myself, it could be worth the extra 4000kbps jump from CRF 22 to CRF 20. Learn more about Stack Overflow the company, and our products. The short answer to the deviation from expected performance is that x265 is still under "heavy development". This should work in your command line. But the quality is not as good as expected. Okay, okay, lets back up a step and look at the bottom 1% again as well. CRF is the best of both worlds. First thing I did was to chop out a minute segment and promptly remove the HDR. As always, start by specifying a preset. H264 is very popular but much less optimized than VP9 or H265. Scroll down to the bottom to see notes on the performance impact of presets with this particular encoder. Anything from 18-40 could give a very decent quality level. First things first, this is NOT a guide for Dolby Vision or HDR10. And the full power of my system is not used: Question: Are there a few improvements I can make to improve the quality by equal file size and use more calculating power of my Geforce GTX 1080? Every modern browser on desktop and mobile supports it, except Safari on iOS. Not sure if theyre agnostic of resolution. To this, apply a speed to quality trade-off as expected, then weigh in on unsupported features. They have some good detail on what things mean. Most time effective web format for converting h.265, The open-source game engine youve been waiting for: Godot (Ep. Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee. However most devices finally have some native h.265 decoding. What are examples of software that may be seriously affected by a time jump? Asking for help, clarification, or responding to other answers. 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. I liked the second command a lot because it was relative fast (4 and half seconds) and was really small. Choose the slowest preset that you have patience for. (h). Which is very similar to others results as well, so Im personally sticking too it. Dealing with hard questions during a software developer interview. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? As I've previously mentioned, the original file resolution is 5000x2700, but we don't use it that big, and we can try to reduce it to the size that is relevant to the page. Ackermann Function without Recursion or Stack. Hmm interesting, may i ask why this scales doesn't correspond? Should I include the MIT licence of a library which I use from a CDN? However, that does not mean smaller file size at the same CRF. shouldnt slower preset produce better picture quality? If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. So lets take a step back and look at the lowest 1% of the frames. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? I may mix it up myself in this article, dont worry about the letter, just the numbers. 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. The webm was quite small, but take many times the amount of time that mp4 took. Because if every frame was that good, we shouldnt need more than 6Mbps x265 or 10Mbps x264 4K video. Super User is a question and answer site for computer enthusiasts and power users. It means there is less differences between the original and the compressed one. Use CRF 23+ for videos in 4K. Asking for help, clarification, or responding to other answers. Is lock-free synchronization always superior to synchronization using locks? Jordan's line about intimate parties in The Great Gatsby? What CRF or settings I should choose for h265 in order to achieve a similiar quality of h264? 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. Encode new files to MP4 or MKV. Think of video format as a container that defines file structure for carrying video and audio streams. These gains will be most pronounced at resolutions of 1080p and higher. I guess this solves my problem. Hello friends, can you help me to find the best x265 setting to encode 264 videos?sorry guys, i still new for ffmpeg. Find centralized, trusted content and collaborate around the technologies you use most. . How to increase the number of CPUs in my computer? Theoretically Correct vs Practical Notation. Thankfully there is a simple answer. The jump from medium to slow is very significant in multiple ways. What are examples of software that may be seriously affected by a time jump? Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. Do people usually encode with 20+ for 1080p? Or for GPU-based encoding, which is much faster, but . FFMPEG gop settings. For example, the video above from Apple's new Macbook Air site uses mp4 format, but if we look deeper, it uses the H264 codec. I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). The best answers are voted up and rise to the top, Not the answer you're looking for? How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? 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. Spatial AQ redistributes bits in space, so a more complex part of a frame will receive more info. How can the mass of an unstable composite particle become complex? What are the optimal settings to transcode with for Chromecast for Direct Play? Why does Jesus turn to the Father to forgive in Luke 23:34? Connect and share knowledge within a single location that is structured and easy to search. Replies: 2 Last Post: 20th Jul 2015, 11:17. So using veryslow is more wise. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. The SSIM result is done frame by frame, so we have to average them all together to see which is best overall. I'm doing some experiments with HEVC x265. (e). What does a search warrant actually look like? If you wanted to target 4 Mbps you'd want to be using veryslow for sure. 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. Note that when using faster presets with the same target bitrate, the resulting quality will be lower and vice-versa. So I had to ask myself: To find out I would need a lot of comparable data. Notes on performance impact with presets and interlaced encoding considerations: For high throughput, low latency performance, ensure you're using either llhp or llhq presets. H265 Settings exclusive to H.265/HEVC encoding. 28 and 23 are the default CRF values of x265 and x264 respectively, hence the supposed equivalence. . -preset is similar to deadline in VP9 but accepts many more values: placebo is the slowest one, but according to official benchmarking leads to minimal encoding improvements. Then I recently read YouTubes suggest guidelines for bitrates. Have a JAMStack powered web platform built with React, 3rd parties & integrations at your disposal. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? The one advantage of hevc_videotoolbox over libx265 is that it supports encoding videos in H265 with alpha channel. ), In pass 1, you can leave audio out by specifying, P. Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. Keep in mind Im talking exclusively of x264 level 5.1+. Thanks for contributing an answer to Super User! As with CRF, choose the slowest -preset you can tolerate, and optionally apply a -tune setting. Jordan's line about intimate parties in The Great Gatsby? So where does that show up on our chart? An addition to the previous comment. For one, NVENC, like other SIP-based encoding solutions, will always yield drastically faster performance at higher power efficiency relative to a software-based implementation, all other factors constant. ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv How can I recognize one? 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). 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. and also why slower and veryslow SSIM is lower than slow preset? FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and ffmpeg - Read raw Data instead of converting to different Format, What is the fastest method to compress videos before sending in React Native Chatting app. Also that I always recommend crf over hard bitrate/filesize because it is really source dependent for saving the proper amount of quality. Should have been already almost completed in all its parts! I have read that previously, Chromecast used to limit playback at 11 Mbps. You need to download the model you want to use (vmaf_4k_v0.6.1.pkl and vmaf_4k_v0.6.1.pkl.model in my case) from https://github.com/Netflix/vmaf/tree/master/model. Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. (g). So, I configured my ipcams to send event videos to a FTP server that saves it locally, and run a script that convert every video into something that can be opened in a generic browser, then send it to a S3 (I am using pyftpdlib + my modifications). I know from some small scale testing that the gaps between the different presents will remain similar (newer article has better graph for that). It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions. Open a 2nd command line and encode another .ts at the same time. To learn more, see our tips on writing great answers. It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? Then, using that information, proceed to the next step. For H265, we need to learn some more extra options. What you want is a min quality level at resulting in a variable bit rate. I see, so because of this heavy development status even if I decide to move from ffmpeg and libx265 to another encoder the results will not change so much right? Additionally to the previously mentioned arguments, ffmpeg VP9 and H265 codecs accept -crf flag . Press J to jump to the feed. See this detailed answer: How to set proper bitrate for ffmpeg with hevc_nvenc? rev2023.3.1.43269. Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. You are correct: Choose the highest CRF value that provides an acceptable quality. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Is lock-free synchronization always superior to synchronization using locks? When the device you are going to watch it on doesnt support it. rev2023.3.1.43269. if you don't, the encoder will choose on for you. ffmpeg -i data2.mp4 -c:v libx265 -c:a copy d2.mp4 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. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? (b). If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. ac3 should give you a 15%+ boost in speed. In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. Use CRF 23+ for videos in 4K. hevc_nvenc option information. Consider your encoding workflow and adjust as necessary. 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? Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. Adapt as necessary to your encoding requirements. 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. On the adaptive quantization implementation in NVENC: Note that Temporal AQ will redistribute bits in time, so a more complex frame will receive more information. 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. nodejs ffmpeg play video at specific time and stream it to client, ffmpeg mp4 video cannot be played in old tv, Duress at instant speed in response to Counterspell. Here we can see x264 has a much harder time at lower bitrates. 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. How do I speed up the encoding? 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. See HWAccelIntro for information on supported hardware H.265/HEVC encoders. Keep in mind that is while still being lesser quality than CRF 18 - Slow. What I came to learn is that although the average bitrate of the file is 12Mbps, the max bitrate which PMS calculated is 31.6 (which probably occurs during action scenes). You can also download a static build, all of which bundle libx265. 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. (Well get to that later.). For everyone else, you can follow instruction on the site. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Using video for animation with proper optimization is always better than GIF and sometimes outperforms native implementations. Slower = better video quality and compression. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? Download the SSIM data as CSV. Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. Does Cosmic Background radiation transmit heat? 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. Currently focused on React, Next.js, Gatsby. 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. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. 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. This is simply for videos using the BT.2020 color primaries. Suspicious referee report, are "suggested citations" from a paper mill? I got 700fps (Yours settings) on a GTX750 (non TI) (the cheaper one), I got 925fps (Your settings with ac3 audio), Answered here: 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.

By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. But x265 is not yet as mature in its development as x264, so take that CRF equivalence with a pinch of salt. What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? You can also download a static build, all of which bundle libx265. Choose a tune (optional). 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. What would be the most time effective format and how to convert a raw h.265 video to it? libvpx-vp9 has the option -deadline which accepts following values: Time to switch to H265 and libx265. Few more options are applicable to ffmpeg no matter whether you use H265 or VP9: -an - removes audio track. 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 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. Viewing options thank you, I'll try it now and feedback you later ^^, I use it to decrease scale. If you require interlaced encoding support, please switch to Pascal or older SKUs instead. Ive specified it to 3x the 8Mbps (so 21M). At what point of what we watch as the MCU movies the branching started? Is Koestler's The Sleepwalkers still well regarded? 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. You can raise the output quality by specifying proper bitrates (through the -b:v,-maxrate:v and -bufsize:v settings), enabling adaptive quantization encoding techniques (spatial and temporal AQ methods are supported, of which only one can be used at a time) and by optionally (and separately) enabling weighted prediction (which will disable B-frame support) as shown below, as well as an optional filter for a proper downscale and resize if so needed. The CRF scales for x264 and x265 do not correspond. If you like I"d be happy to test one of your .ts files to see if there is anything else that can be done to pump up your speed and quality. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. FFmpeg: For NVENC, what is a concurrent surface? Antn Garcia. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Why using b-frames does not reduce the size of my video (using ffmpeg and nvenc)? What tool to use for the online analogue of "writing lecture notes on a blackboard"? Modern web development every year applies new standards for performance. I don't want others to keep searching for the answer. But based on just the average, slow was the obvious choice, as even bumping up the CRF from 18 to 16 didnt match the quality. Even if there is no sound in a file, there could be empty audio track information that will occupy some additional weight, so always use it for muted videos.
