There is no such thing as "proper bitrate". Suspicious referee report, are "suggested citations" from a paper mill? 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. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? My experience with using nvenc is that you need to tell it what bitrate you want -- it defaults to VBR, which is fine, but no amount of tuning makes up for the fact that it always wants to give you a 2M average bitrate no matter what resolution file you feed it. Note: Windows users should use NUL instead of /dev/null and ^ instead of \. Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. Keep in mind Im talking exclusively of x264 level 5.1+. Is a wanted design with a bigger amount of CRF values or could be considered this way because libx265 is still not mature enough in ffmpeg? Is email scraping still a thing for spammers. The real question is HDR. Why using b-frames does not reduce the size of my video (using ffmpeg and nvenc)? They have some good detail on what things mean. For this, you can use -c:v flag. 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. 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). Now, if I have a super computer and unlimited storage, I might lean towards CRF 18 or maybe even 16, but still wouldnt feel the need to take it the whole way to CRF 14 and veryslow or anything crazy. 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. I tried to a post a total comment but got a mess. 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. I tried H.265 10 bit, H.265 12 bit, and H.264 10 bit, and they all ended up looking washed out compared to the original file. ffmpeg creates large compressed files for tiny videos? This is simply for videos using the BT.2020 color primaries. Hope that helps, thanks for asking and happy to help! Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. Really awesome!

Easiest way to remove 3/16" drive rivets from a lower screen door hinge? Super User is a question and answer site for computer enthusiasts and power users. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. To learn more, see our tips on writing great answers. So I had to ask myself: To find out I would need a lot of comparable data. See a list of available x265 profiles. and our Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. We haven't used it in VP9 WebM because its architecture does not require this and always guarantees progressive loading. In our case it is 3840px width. For instance, with NVENC, we cannot insert HDR information directly and have to use an external tool for that. 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. Thanks for contributing an answer to Stack Overflow! So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. 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.

I will make a few tests with h264. (g). Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. is it worth to spend more time to encode slower preset? I may mix it up myself in this article, dont worry about the letter, just the numbers. Start by understanding the encoder's options. Connect and share knowledge within a single location that is structured and easy to search. Find centralized, trusted content and collaborate around the technologies you use most. Why does Jesus turn to the Father to forgive in Luke 23:34? Call up the appropriate video and audio encoders, and pass necessary arguments to them, such as mappings, bitrates, encoder presets, etc. 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). Using video for animation with proper optimization is always better than GIF and sometimes outperforms native implementations. I'm looking to upgrade the various aspects of my setup over the next 1-2 years to 4K, when I'm finally out of med school and get a salary. Then, using that information, proceed to the next step. 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. Would the reflected sun's radiation melt ice in LEO? That said, you can try to establish your own calibration between the current versions of the encoding libraries in your ffmpeg by running the following command, which executes two popular video quality metrics: The final lines of the console output will contain: So, run the command once with the x264 output and once with x265 and compare with different x265 outputs, till you get similar measures. I use both as .bat files. and also why slower and veryslow SSIM is lower than slow preset? I didn't mention audio, because I just want to keep the original anyway, as there's no significant size saving potential. If you want a single go to setting for encoding, based on my personal testing CRF 20 with Slow preset looks amazing (but may take too long if you are using older hardware). Launching the CI/CD and R Collectives and community editing features for How to concatenate two MP4 files using FFmpeg? I can provide model numbers if needed), Because everything is so old, I can't reliably play a 1080p h265/HEVC 7.1 movie at full quality without some stuttering. The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? Find centralized, trusted content and collaborate around the technologies you use most. The original was H.265 encoded with a .ts extension. Choose the slowest preset that you have patience for. 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. If the same information really answers both questions, then one question (usually the newer one) should be closed as a duplicate of the other. Modern video codecs can deliver excellent quality while preserving a very reasonable size. Slower = better video quality and compression. Convert ffmpeg encoding from libx264 to h264_nvenc. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? So remember, Handbrake recommends a range of 22-28 CRF, and I personally cannot see any visual loss at CRF 20. 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. 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. However, CRF shows its true edge on the lowest 1%, easily beating out ABR at every turn. Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. Attempting to do so will result in encoder initialization failure. Why did the Soviets not shoot down US spy satellites during the Cold War? However, I head that this cap was removed. Should I include the MIT licence of a library which I use from a CDN? Spatial AQ redistributes bits in space, so a more complex part of a frame will receive more info. A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. 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. 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? If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. First thing I did was to chop out a minute segment and promptly remove the HDR. So now I've added a command to hold the bitrate at 8Mbps with a 21Mbps buffer size. You can speed up and slow down encoding ruins presets. 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. Thanks @szatmary. 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. Because if every frame was that good, we shouldnt need more than 6Mbps x265 or 10Mbps x264 4K video. There's a TLDR at the end. 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. Thanks for contributing an answer to Stack Overflow! Press question mark to learn the rest of the keyboard shortcuts. In this data set, slow is the clear winner in multiple ways. It means there is less differences between the original and the compressed one. Higher presets (such as the default medium) have rapidly diminishing returns in quality output while at the same time incurring significant slowdowns in encoder throughput. 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 open-source game engine youve been waiting for: Godot (Ep. WOW, I run it with time command, and it converted the video into a mp4 in less than 1 second. Here is the order in which you have to pass arguments to FFmpeg: (a). 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. The number of distinct words in a sentence, Torsion-free virtually free-by-cyclic groups. Thankfully there is a simple answer. (As a heads up h.265 is the specification, and x265 is encoder for it. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. To learn more, see our tips on writing great answers. Call up the binary. This time with Pre-Analysis. The number of distinct words in a sentence. But that's probably not what you want. I dont use x265 for anything besides 4k HDR content. Note that when using faster presets with the same target bitrate, the resulting quality will be lower and vice-versa. Introducing FastFlix AV1 encoder GUI and more! How do I speed up the encoding? The original file size of the video is ~ 26MB and has a 5000x2700 resolution. Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. Planned Maintenance scheduled March 2nd, 2023 at 01:00 AM UTC (March 1st, How do I convert 10-bit H.265 / HEVC videos to H.264 without quality loss? Connect and share knowledge within a single location that is structured and easy to search. as in example? 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. Is email scraping still a thing for spammers. Choose the slowest preset that you have patience for. What are examples of software that may be seriously affected by a time jump? Asking for help, clarification, or responding to other answers. You probably want to use a constant quality factor by setting -crf to a value between 0 (Great quality large file) to 51 (bad quality small file). Which is very similar to others results as well, so Im personally sticking too it. In the past, I went straight to Handbrakes documentation. Declare your inputs. 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). [] 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. Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. Also, I find it much easier to share single ffmpeg commands across the team instead of showing where to click things in Handbrake. *** CRF 20-23 for most 1080p videos is enough. Famous codecs are H264, H265, and VP8/9. 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. FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. 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. For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. Why are non-Western countries siding with China in the UN? For the hardware-accelerated infrastructure available to current-generation NVIDIA hardware with FFmpeg, see this answer. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 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. 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. The best answers are voted up and rise to the top, Not the answer you're looking for? Applications of super-mathematics to non-super mathematics. 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? Help with ffmpeg settings H265. Just curious. 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. So what *is* the Latin word for chocolate? I tried to look up the documentation, but i simple don't have the multimedia background to understand it. Unfortunately, the same can't be said about videos. It is not a royalty-free codec - perhaps, that is why the adoption rate is much less than of WebM's. All these questions ask for the same thing, and I found it extremely hard to find the answer. Learn more about Stack Overflow the company, and our products. Ive got the right version of FFmpeg with libvmaf but am having a hard time getting the right CLI parameters. However, that does not mean smaller file size at the same CRF. Not sure if theyre agnostic of resolution. Handbrake 1.2.2. rev2023.3.1.43269. 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: Keep in mind that is while still being lesser quality than CRF 18 - Slow. On the section of video I chose, x264 needed considerably more bitrate to achieve the same score. You could probably lower those a little bit if you want, too. ffmpeg is a CLI tool and it has a lot of options that is nice to know. The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. CRF works just like in x264, so choose the highest value that provides an acceptable quality. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. You can change this by adding -b:v option to ffmpeg. On my computer (a fairly good laptop) it usually takes half the video playtime to convert into a mp4 using a generic ffmpeg command that i simple copy and paste from stackoverflow. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. As with CRF, choose the slowest -preset you can tolerate, and optionally apply a -tune setting. Thanks for contributing an answer to Super User! Is this the best possible solution, or is there a better way of doing this? But after even a basic compression it cuts down to 1MB. x265 uses CRF 18 by default. -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. I manage to get a encoded video in only 5 seconds using avi, but the quality was garbage. And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. 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. FFmpeg best settings to encode Blu-Ray. Consider your encoding workflow and adjust as necessary. However, Im really only dealing with 1080p rips Curious if you have any data on the difference between Medium and Slow settings at 1080p? Centering layers in OpenLayers v4 after layer loading. 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. I don't want others to keep searching for the answer. Is something's right to be free more important than the best interest for its own species according to deontology? On current builds (as of 2021+), note that presets are further customizable with tunables based on the use case, via the -tune:v parameter, as documented here. Making statements based on opinion; back them up with references or personal experience. 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 know from some small scale testing that the gaps between the different presents will remain similar (newer article has better graph for that). How do I avoid objects having flickering edges when I encode a screen recording to mp4 using x264 and ffmpeg? Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. 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 While its narrow versatility makes it incredibly frustrating to work with, there's never been another video player in history that scrubs as well, or uses laptop CPU/battery as efficiently. What does a search warrant actually look like? rev2023.3.1.43269. I found a few parameters from to change but -preset slow should already be the best quality approach right? By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Asking for help, clarification, or responding to other answers. 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. Add it next to your -c:v h264_nvenc -c:a ac3 You should also be able to push 2 sessions. Privacy Policy. By default, this is disabled, and it is generally not required to set a tune option. 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.
