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. The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. FFmpeg: For NVENC, what is a concurrent surface? CRF is the best of both worlds. Profiles can be set via the -profile:v option, similar to libx264. 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? How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Best settings for converting from h264 to hevc? The command I use boils down to ffmpeg.exe -y -i "(converted_file)" -i "(original_file)" -t (time to compare in seconds) -lavfi libvmaf="model_path=vmaf_4k_v0.6.1.pkl:log_path=details.txt;[0:v][1:v]ssim=1" -report -f null -\n. Have you seen the h264 & h265 pages? So, I'll link to the other answer that I posted. As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). I wanted to thank you for all this great work youve done on these articles. For this, you can use -c:v flag. 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. Acceleration without force in rotational motion? If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. Does With(NoLock) help with query performance? Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? 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. Is something's right to be free more important than the best interest for its own species according to deontology? Anything from 18-40 could give a very decent quality level. For everyone else, you can follow instruction on the site. ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc. (f). Encode new files to MP4 or MKV. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. My first step is to convert images into yuv format: ffmpeg -f image2 -i "C:\DATA FOLDER\images%d.png" video.yuv And I try to convert it as a .mkv file, losslessly: In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.

I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). In the past, I went straight to Handbrakes documentation. It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? I've gone through this sub and tried to improve my transcodes, but I'm still not 100% there. These gains will be most pronounced at resolutions of 1080p and higher. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. But that's probably not what you want. Even if your source video doesnt use the HDR color space, it compresses better. (b). 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. Was Galileo expecting to see so many stars? 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. Why using b-frames does not reduce the size of my video (using ffmpeg and nvenc)? This method is generally used if you are targeting a specific output file size and output quality from frame to frame is of less importance. If you wish to master the tool, you will have to learn how to use flags. 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. Find centralized, trusted content and collaborate around the technologies you use most. The original was H.265 encoded with a .ts extension. Thanks @szatmary. from the chart SSIM difference is very low. hevc_videotoolbox is a macOS-specific library that gives native hardware acceleration for H265 encoding. You can speed up and slow down encoding ruins presets. I have a raw footage and the quality of details of h264 with same CRF setting looks better than h265. If youre a macOS user, use brew to install it. Currently focused on React, Next.js, Gatsby. 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. Adding -crf 0 is not required. I got 700fps (Yours settings) on a GTX750 (non TI) (the cheaper one), I got 925fps (Your settings with ac3 audio), Answered here: 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 does Jesus turn to the Father to forgive in Luke 23:34? In this data set, slow is the clear winner in multiple ways. But when I looked at the videos I was enjoying just fine at CRF 22, they were mostly coming out with less than a 10Mbps bitrate. Okay, okay, lets back up a step and look at the bottom 1% again as well. 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. Thanks for contributing an answer to Stack Overflow! Really awesome! If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? You're still doing high bitrate encoding. The real question is HDR. I have only recently discovered FFmpeg and tried using the x265 video codec to reduce the video stream size for some videos, and realized that I can achieve tremendous space savings, especially for video recorded via smarthphones. 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. Thankfully there is a simple answer. ffmpeg -i input.ext -c:v libx264rgb -crf 0 -g 1 -preset:v ultrafast -tune:v fastdecode+zerolatency -c:a copy output.mkv Intra will be faster for decoding and seeks, x264 will be faster than x265 A lot of it depends on your hardware, and personal tolerance for speed If it's still too "slow" for you - you can try the proxy edit feature When the device you are going to watch it on doesnt support it. (Well get to that later.). compression.ru/video/codec_comparison/hevc_2015/. Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee. When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. So I had to ask myself: To find out I would need a lot of comparable data. shouldnt slower preset produce better picture quality? So where does that show up on our chart? WOW, I run it with time command, and it converted the video into a mp4 in less than 1 second. The Compilation Guides show you how to do that. All Rights Reserved. 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. In the same breath, note that NVIDIA has explicitly disabled interlaced encoding on Turing across all tiers, even the 1650 uses the older Volta NVENC encoder. 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. When comparing to standard 4.1 profile than yes, x265 outperform it in almost any metric. Although I've been using Plex for years, my setup is far inferior to most of the people on this forum. Download the SSIM data as CSV. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. As I'm new to this, I tried doing some research and found that mostly it's about choosing the correct CRF and preset, so I am thinking it would be sufficient to write a script which iterates through these, creating samples which I could look at and decide what's the best option for a given (set of) video(s). Does Cosmic Background radiation transmit heat? That way I know I should never be disappointed. Note: Windows users should use NUL instead of /dev/null and ^ instead of \. 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. Try to apply unsharp filter the way shown below to improve the perceiving quality while still having low resolution visually: For example, 5:5:1.0 will result in medium sharpness; for the light one, try to use 3:3:1.0, and for the strong one, pass down 9:9:1.0. 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. Suspicious referee report, are "suggested citations" from a paper mill? Should have been already almost completed in all its parts! Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). FFMPEG gop settings. Quality perception for dynamic pictures differs severely compared to static images, so hacks like this help your video appear of good quality even in case of further reducing the size of a video. 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. There aren't some commercial products based on x265 nowadays? The number of distinct words in a sentence. Is email scraping still a thing for spammers. You can indicate this by, i can link the answer to the other question. Why are non-Western countries siding with China in the UN?

By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. There are two most popular tools for video optimization -Handbrake andffmpeg. 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. - Code Calamity, Animated AVIF is finally coming to Firefox, AMD improves video encoding yet again! Slower = better video quality and compression. Jordan's line about intimate parties in The Great Gatsby? Do not leave these blank. Create an account to follow your favorite communities and start taking part in conversations. Handbrake 1.2.2. With ffmpeg, it'd look like this: ffmpeg -i input.mp4 -c:v libx264 -crf 23 output.mp4 For x265, the default CRF is 28: ffmpeg -i input.mp4 -c:v libx265 -crf 28 output.mp4 For libvpx, there is no default, and CRF can range between 0 and 63. Replies: 2 Last Post: 20th Jul 2015, 11:17. 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. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Which is very similar to others results as well, so Im personally sticking too it. How to increase the number of CPUs in my computer? Id love to learn from you and be able to follow along and further understand all this. Still a vlc bad decoding + libx265 too young? It seems like a flaw in the encoder; it performs predictably in every other respect, but it needs (for example) -b:v 4M for a 720p file or -b:v 8M for 1080p. Thank 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. Call up the appropriate video and audio encoders, and pass necessary arguments to them, such as mappings, bitrates, encoder presets, etc. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? Put simply, the closer the result is to 1 the better. This is a good starting point on why these values matter. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? . Thus comparing the two encoders via their default 8-bit compressors.I found this code to convert the 10-bit HDR yuv420p10le colorspace down to the standard yuv420p 8-bit colorspace from the colourspace blog so props to them for having a handy guide just for this. 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. Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! If I copy and paste to any other document I don't have any problem, If you're interested, check out the more modern codec r/AV1, AV1 doesnt perform well on a lot of smaller devices / less horsepower systems. Thanks for contributing an answer to Stack Overflow! A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. Asking for help, clarification, or responding to other answers. Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. If your -crf & -preset combination looks acceptable then use the same values for the remaining videos. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. 20 medium 66.884759 0.9598, 22 slow 67.187793 0.959167 Not sure if theyre agnostic of resolution. What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? q I dont use x265 for anything besides 4k HDR content. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? ***### Encode video as x265 HEVC 10bit.ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv### Same as above, but as a two-pass x265 HEVC 10bit encode.ffmpeg -y -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=1 -an -f null /dev/null && \ffmpeg -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=2 -c:a copy "output".mkv. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. I mainly use Handbrake now use ffmpeg because I learned Handbrake only has a 8-bit internal pipeline. I tried to a post a total comment but got a mess. 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. Nothing to do specifically with libx265 included with ffmpeg See. 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. Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. Older versions must use -x265-params keyint=1. First things first, this is NOT a guide for Dolby Vision or HDR10. ffmpeg is a CLI tool and it has a lot of options that is nice to know. The SSIM result is done frame by frame, so we have to average them all together to see which is best overall. For WebM, it's VP8 and VP9, while in mp4 could be almost anything. It can carry video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with theVorbisorOpusaudio codecs. Privacy Policy. I will make a few tests with h264. 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. Keep in mind Im talking exclusively of x264 level 5.1+. Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. They claim that a 4K video coming into their site should optimally be 35~45Mbps when encoded with the older x264 codecs. This guide focuses on the encoder libx265 which can offer around 2550% bitrate savings compared to H.264 video encoded with libx264, while retaining the same visual quality. Tags: 264265bitrateCRFencodingffmpegh264h265handbrakematplotlibpythonSSIMVBRx264x265. Attempting to do so will result in encoder initialization failure. There is no such thing as "proper bitrate". The honest to god true answer is it depends, however I find that answer unsuitable for my own needs. They have some good detail on what things mean. rev2023.3.1.43269. Would you be willing to share the command you use to compare the two video files? Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. Maybe something more visible at lower bitrates? The absolute path to the output file. Antn Garcia. See FFmpeg Wiki: H.265 for more info. Is there a more recent similar source? ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv The webm was quite small, but take many times the amount of time that mp4 took. Is this enough, or should I take some other things into consideration as well? Making statements based on opinion; back them up with references or personal experience. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? Frameworks compete by optimizing network requests, images, and code to achieve a blazing-fast loading experience. An addition to the previous comment. Use CRF 23+ for videos in 4K. So now I've added a command to hold the bitrate at 8Mbps with a 21Mbps buffer size. 28 and 23 are the default CRF values of x265 and x264 respectively, hence the supposed equivalence. FFmpeg supports hardware accelerated decoding and encoding via the hwaccel cuda, h264_cuvid, hevc_cuvid and h264_nvenc, hevc_nvenc modules. What CRF or settings I should choose for h265 in order to achieve a similiar quality of h264? What are some tools or methods I can purchase to trace a water leak? Would the reflected sun's radiation melt ice in LEO? Hope that helps, thanks for asking and happy to help!

If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. 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. Predictable file sizes are a priority. 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). You can remove this scale=858:482: from my scripts. To learn more, see our tips on writing great answers. 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. Modern web development every year applies new standards for performance. Note that when using faster presets with the same target bitrate, the resulting quality will be lower and vice-versa. To learn more, see our tips on writing great answers. @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. How can I recognize one? How to make PNG video render into 10bit h.264 matroska/avi file? So lets get a little more apples to apples. You canread thisdoc for more info on this. Find centralized, trusted content and collaborate around the technologies you use most. 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. But that impacts quality so you will need to test to see what quality is acceptable. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. Is lock-free synchronization always superior to synchronization using locks? Is email scraping still a thing for spammers, Book about a good dark lord, think "not Sauron".

Pythons New Structural Pattern Matching! )Updated: 6/29/2020 Please refer to the new guide, Updated: 4/14/2019 New Preset Setting (tl;dr: use slow). CRF affects the quality. rev2023.3.1.43269. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. The short answer to the deviation from expected performance is that x265 is still under "heavy development". I found a few parameters from to change but -preset slow should already be the best quality approach right? So what *is* the Latin word for chocolate? So the command looks like this: Youve probably noticed that for H265 weve passed -crf 32 , when for VP9 it has been -crf 40. Theoretically Correct vs Practical Notation.
