It is well known between pros that SSIM and PSNR are not good measures or SUBJECTIVELY PERCEIVABLE quality. 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. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. All tests run using one of the animations we've made for a recent project. hevc_nvenc option information. 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. Use CRF 23+ for videos in 4K. I used a three minute 4K HDR clip, using Handbrake to only modify which present was used. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. The one advantage of hevc_videotoolbox over libx265 is that it supports encoding videos in H265 with alpha channel. 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. 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). Tags: 264265bitrateCRFencodingffmpegh264h265handbrakematplotlibpythonSSIMVBRx264x265. 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. To some, including myself, it could be worth the extra 4000kbps jump from CRF 22 to CRF 20. An addition to the previous comment. . WebM is an open, royalty-free media file format designed for the web. Acceleration without force in rotational motion? Libvorbis for audio seems slow. Even though it does cost double the time of medium it really delivers in the quality department. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Find centralized, trusted content and collaborate around the technologies you use most. All Rights Reserved. For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. Then in three years H.266 / VVC toolsets will probably be popping up. What does a search warrant actually look like? It can carry video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with theVorbisorOpusaudio codecs. Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. Is email scraping still a thing for spammers. Any idea what might cause this? Not bad, but we can do better! Introducing FastFlix AV1 encoder GUI and more! Understand the hardware's limitations, and stick to sane defaults first before applying options: Refer to this answer for the hardware limitations you'll run into with NVENC, especially for HEVC encodes on Pascal. Note that when using faster presets with the same target bitrate, the resulting quality will be lower and vice-versa. I have to use a separate comments for every statement. My observation is confined to standalone x265 or its deployment, whether in ffmpeg or anything else.

Connect and share knowledge within a single location that is structured and easy to search. 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. Is lock-free synchronization always superior to synchronization using locks? 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. Also, I find it much easier to share single ffmpeg commands across the team instead of showing where to click things in Handbrake. Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. libvpx-vp9 has the option -deadline which accepts following values: Time to switch to H265 and libx265. rev2023.3.1.43269.

Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. This is simply for videos using the BT.2020 color primaries. [] 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. Declare your inputs. Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! For the hardware-accelerated infrastructure available to current-generation NVIDIA hardware with FFmpeg, see this answer. Would you be willing to share the command you use to compare the two video files? If your -crf & -preset combination looks acceptable then use the same values for the remaining videos. Hmm interesting, may i ask why this scales doesn't correspond? For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. I use both as .bat files. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup.

Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git 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. This is best explained with an example. It means there is less differences between the original and the compressed one. Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. Additionally to the previously mentioned arguments, ffmpeg VP9 and H265 codecs accept -crf flag . H265 Settings exclusive to H.265/HEVC encoding. Add it next to your -c:v h264_nvenc -c:a ac3 You should also be able to push 2 sessions. 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. 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. I tried to look up the documentation, but i simple don't have the multimedia background to understand it. I know from some small scale testing that the gaps between the different presents will remain similar (newer article has better graph for that). So lets take a step back and look at the lowest 1% of the frames. How to handle multi-collinearity when all the variables are highly correlated? Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. So what *is* the Latin word for chocolate? See FFmpeg Wiki: H.264 for more info. Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. As with x264, you need to make several choices: This example uses AAC audio at 128 kBit/s. But that's probably not what you want. Or for GPU-based encoding, which is much faster, but . I tried to a post a total comment but got a mess. You will have to tweak A LOT of the extra complex settings of x265 encoder to even MATCH x264, let alone surpass it in size to perceivable quality, and by the time you do, you will see that x265 is just a order of magnitude slower than x264 to achieve marginally better results which is very problematic with 4k encodes. Is Koestler's The Sleepwalkers still well regarded? ffmpeg -c:v libx265 -preset fast -crf 28 -tag:v hvc1 -c:a eac3 -b:a 224k -i <source> <target>. Of course, these metrics aren't perfect but you can use them as a rough guide to establish equivalence. Video and audio streams inside these containers are multimedia data encoded with codec. In this case, you are using two different encoders, so you get different bitrates. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Not the answer you're looking for? Every modern browser on desktop and mobile supports it, except Safari on iOS. The slow preset was used as it was determined to be an ideal choice in previous tests. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. 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). 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. Consider your encoding workflow and adjust as necessary. 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. So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. (c). How can the mass of an unstable composite particle become complex? If libx265 is too slow use libx264 which is faster but file size will be bigger. See FFmpeg Wiki: H.265 for more info. Making statements based on opinion; back them up with references or personal experience. (g). This is why the duplicate flag has been declined. Suspicious referee report, are "suggested citations" from a paper mill? Because if every frame was that good, we shouldnt need more than 6Mbps x265 or 10Mbps x264 4K video. The number of distinct words in a sentence, Torsion-free virtually free-by-cyclic groups. Here is the order in which you have to pass arguments to FFmpeg: (a). Attempting to do so will result in encoder initialization failure. 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. For H265, we need to learn some more extra options. You're still doing high bitrate encoding. You can list private options available in this encoder with ffmpeg -h encoder=libx265. Use CRF 23+ for videos in 4K. Those other encoders might be better - I haven't studied that PDF closely. You can speed up and slow down encoding ruins presets. Why using b-frames does not reduce the size of my video (using ffmpeg and nvenc)? Using video for animation with proper optimization is always better than GIF and sometimes outperforms native implementations. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Video Production Stack Exchange is a question and answer site for engineers, producers, editors, and enthusiasts spanning the fields of video, and media creation. A home for professional coders articles, opinions and ideas. Start by understanding the encoder's options. 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). Sorry for the long post. However, I head that this cap was removed. 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. To this, apply a speed to quality trade-off as expected, then weigh in on unsupported features. 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. 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. What are some tools or methods I can purchase to trace a water leak? Have you seen the h264 & h265 pages? In the past, I went straight to Handbrakes documentation. In ffmpeg documentation that you linked is said that x265 crf 28 is roughly equivalent to x264 crf 23. Pythons New Structural Pattern Matching! -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. Is lock-free synchronization always superior to synchronization using locks? Theoretically Correct vs Practical Notation. how to use FFMPEG to transcode h264 to h265 on Ubuntu 12.04? Note that the preset selected has the greatest impact on throughput, followed by the preset options (such as the rate control method in use) that you can optionally override if desired. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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: And embedding it to the project with this html getting the best possible result. Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. 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. The number of distinct words in a sentence. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. The Compilation Guides show you how to do that. 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 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. Not the answer you're looking for? Centering layers in OpenLayers v4 after layer loading. In this test, I encoded all videos with ffmpeg using the default presents. 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.

Choose a tune (optional). Note: Windows users should use NUL instead of /dev/null and ^ instead of \. For WebM, it's VP8 and VP9, while in mp4 could be almost anything. Thanks for contributing an answer to Stack Overflow! There's a TLDR at the end. 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. 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. Thanks for contributing an answer to Video Production Stack Exchange! 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. 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. Convert ffmpeg encoding from libx264 to h264_nvenc. Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. PTIJ Should we be afraid of Artificial Intelligence? 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. 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. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. I tried encoding some 4K HDR files using Handbrake and they look washed out. 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. For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. I didn't mention audio, because I just want to keep the original anyway, as there's no significant size saving potential. FFmpeg commands I using are the following: I used 30 as CRF for testing purposes because the artifacts are more visible :). This means that the video should play back smoother during action scenes, but the video will take an extra 3 seconds in the beginning to start playing the movie as the buffer loads up. By Edgewall Software Making statements based on opinion; back them up with references or personal experience. I personally think the extra 2500kbps for the large jump in minimum quality from CRF 24 to CRF 22 is a must. hevc_videotoolbox is a macOS-specific library that gives native hardware acceleration for H265 encoding. Really awesome! The original was H.265 encoded with a .ts extension. CRF is the best of both worlds. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. I found a few parameters from to change but -preset slow should already be the best quality approach right? How do I avoid objects having flickering edges when I encode a screen recording to mp4 using x264 and ffmpeg? Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. The SSIM result is done frame by frame, so we have to average them all together to see which is best overall. The Compilation Guides show you how to do that. 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. These gains will be most pronounced at resolutions of 1080p and higher. Choose a CRF. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. But x265 is not yet as mature in its development as x264, so take that CRF equivalence with a pinch of salt. Connect and share knowledge within a single location that is structured and easy to search. Also h264 is faster to encode that h265, but again it will impact quality. PTIJ Should we be afraid of Artificial Intelligence? For more information, please see our 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. Help with ffmpeg settings H265. If the same information really answers both questions, then one question (usually the newer one) should be closed as a duplicate of the other. 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. Your mileage will definitely vary, based on your source content, filter chains in use, specific pltform configuration variables (such as your GPU and driver versions), etc. Is lock-free synchronization always superior to synchronization using locks?

I believe that the last value of 31.6 Mbps is exceeding the capacity of the Chromecast v2. It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. Was Galileo expecting to see so many stars? Suspicious referee report, are "suggested citations" from a paper mill? (This will generate a logfile that ffmpeg needs for the second pass. The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. Code Calamity 2023. shouldnt slower preset produce better picture quality? By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Strange that the video playback stops if the transcoder gets too far ahead, reaching its buffer limit, on the audio track only? Jordan's line about intimate parties in The Great Gatsby? Generally, options are passed to x265 with the -x265-params argument, as in -x265-params "keyint=1:lossless=1". But the quality is not as good as expected. ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless. By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . How do I speed up the encoding? 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. Anything from 18-40 could give a very decent quality level. 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. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. - Code Calamity, Animated AVIF is finally coming to Firefox, AMD improves video encoding yet again! ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc.

Please read the new article for saving HDR.I have historically been using the older x264 mp4s for my videos, as it just works on everything. I started with a 4K HDR example video. Is email scraping still a thing for spammers. 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. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Should have been already almost completed in all its parts! As always, start by specifying a preset. If you look at the PDF I linked in the last comment, there are many encoders out there - most proprietary. The number of distinct words in a sentence. The webm was quite small, but take many times the amount of time that mp4 took. Keep in mind that is while still being lesser quality than CRF 18 - Slow. It is less efficient in terms of optimization and does not have Constant Quality mode (-crf) and presets we used in the previous example. Thanks for contributing an answer to Stack Overflow! Profiles can be set via the -profile:v option, similar to libx264. In this data set, slow is the clear winner in multiple ways.
