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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. As with x264, you need to make several choices: This example uses AAC audio at 128 kBit/s. 20 medium 66.884759 0.9598, 22 slow 67.187793 0.959167 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. At this point, it would be imperative to mention that decoders have specific constraints, such as expected input resolutions, supported codecs, etc, and as such, it's recommended that in production, to determine and validate the need for hardware-accelerated decoders as failure at this stage results in a failed encode and is unrecoverable. Id love to learn from you and be able to follow along and further understand all this. 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. 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. I don't want others to keep searching for the answer. 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. 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? Any idea what might cause this? (And if I ran these tests first, I would have even used slow for all the other testing!). I guess this solves my problem. Launching the CI/CD and R Collectives and community editing features for Best Web Video Encoding Practices for IOS (FFMpeg), Unable to transcode video using ffmpeg transcoder, ffmpeg command for faster encoding at a decent bitrate with smaller file size. 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. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. If the same information really answers both questions, then one question (usually the newer one) should be closed as a duplicate of the other. WebM is an open, royalty-free media file format designed for the web. Making statements based on opinion; back them up with references or personal experience. 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. Attempting to do so will result in encoder initialization failure. Keyframes need more data then other frame types to avoid pulsing poor quality keyframes. as in example? 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. . Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. Note that hevc_nvenc will almost produce larger files than libx265 at a given quality because it not as efficient as an encoder. (c). When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. Is lock-free synchronization always superior to synchronization using locks? Every modern browser on desktop and mobile supports it, except Safari on iOS. It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. 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). See FFmpeg Wiki: H.265 for more info. Jordan's line about intimate parties in The Great Gatsby? Find centralized, trusted content and collaborate around the technologies you use most. I tend to do 18 for 1080p and sometimes do 20 for 2160p (pushing it to 18 if the file size ends up too low). CRF is the best of both worlds. Unfortunately, the same can't be said about videos. H264 is very popular but much less optimized than VP9 or H265. Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ? Hope that helps, thanks for asking and happy to help! So where does that show up on our chart? 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 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. ffmpeg is a CLI tool and it has a lot of options that is nice to know. To learn more, see our tips on writing great answers. I will make a few tests with h264. 22 medium 65.979806 0.959182. Choose the slowest preset that you have patience for. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. 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. When you omit this option, ffmpeg uses -crf 32 for VP9 by . 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. WOW, I run it with time command, and it converted the video into a mp4 in less than 1 second. Now this is an apples to oranges comparison. So lets take a step back and look at the lowest 1% of the frames. Dealing with hard questions during a software developer interview. A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? So what *is* the Latin word for chocolate? An addition to the previous comment. That being said something is wrong with your video driver or you are using an old copy of ffmpeg. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Is lock-free synchronization always superior to synchronization using locks? You could probably lower those a little bit if you want, too. If so, what would the best solution? Even if your source video doesnt use the HDR color space, it compresses better. It is not a royalty-free codec - perhaps, that is why the adoption rate is much less than of WebM's. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. Older versions must use -x265-params keyint=1. There is only one time to not use it. When the device you are going to watch it on doesnt support it. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. So remember, Handbrake recommends a range of 22-28 CRF, and I personally cannot see any visual loss at CRF 20.

If youre a macOS user, use brew to install it. Thanks for contributing an answer to Super User! Hey Jamie, sure thing! In this data set, slow is the clear winner in multiple ways. In ffmpeg documentation that you linked is said that x265 crf 28 is roughly equivalent to x264 crf 23. 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. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. @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. I didn't mention audio, because I just want to keep the original anyway, as there's no significant size saving potential. Keep in mind Im talking exclusively of x264 level 5.1+. And bitrate directly correlates to file size. [] 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. The honest to god true answer is it depends, however I find that answer unsuitable for my own needs. Nothing to do specifically with libx265 included with ffmpeg See. *** CRF 20-23 for most 1080p videos is enough. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Predictable file sizes are a priority. Is there a more recent similar source? 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. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? For some videos, you can try using the low resolution option, but on retina screens, it could lead to a blurry picture. Why did the Soviets not shoot down US spy satellites during the Cold War? You can change this by adding -b:v option to ffmpeg. Does With(NoLock) help with query performance? (g).

Here we can see x264 has a much harder time at lower bitrates. To make your file compatible with Apple "industry standard" H.265 you have to add the following argument -tag:v hvc1. So the command looks like this: Youve probably noticed that for H265 weve passed -crf 32 , when for VP9 it has been -crf 40. I mainly use Handbrake now use ffmpeg because I learned Handbrake only has a 8-bit internal pipeline. This topic can be confusing, so it's important to learn the difference. Thanks @szatmary. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Applications of super-mathematics to non-super mathematics. 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. Making statements based on opinion; back them up with references or personal experience. I hope you found this information as useful as I did, if you have any thoughts or feedback please let me know! Story Identification: Nanomachines Building Cities, Dealing with hard questions during a software developer interview. You can remove this scale=858:482: from my scripts. Famous codecs are H264, H265, and VP8/9. Powered by Trac 1.4.2 Using video for animation with proper optimization is always better than GIF and sometimes outperforms native implementations. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. 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. 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. Add it next to your -c:v h264_nvenc -c:a ac3 You should also be able to push 2 sessions. What are some tools or methods I can purchase to trace a water leak? (d). Call up the binary. Is email scraping still a thing for spammers. 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). In this case, you are using two different encoders, so you get different bitrates. Setting up NVENC (for Streaming) Modern OBS Studio has two ways to achieve the expected quality: the built-in NVENC H.264 (new) and the addition from StreamFX called NVIDIA NVENC H.264/AVC (via FFmpeg). To learn more, see our tips on writing great answers. 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. 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. Download the SSIM data as CSV. I used a three minute 4K HDR clip, using Handbrake to only modify which present was used. Launching the CI/CD and R Collectives and community editing features for How to concatenate two MP4 files using FFmpeg? Planned Maintenance scheduled March 2nd, 2023 at 01:00 AM UTC (March 1st, We've added a "Necessary cookies only" option to the cookie consent popup, How to specify CRF quality settings for different encoding software, Trying to sync audio in mpeg2 video whose video freezes first 8 seconds in playback, FFMpeg concat demuxer corrupted output (freezed video on some concatenated parts). I have to use a separate comments for every statement. This time with Pre-Analysis. For more information, please see our Please do not post the same answer to multiple questions. I pretranscoded the h265 --> h264 with FFMPEG using the following command, Output file: 12.1 Mbps 1080p h264 7.1 AAC mkv. Although I've been using Plex for years, my setup is far inferior to most of the people on this forum. Would the reflected sun's radiation melt ice in LEO? Anything from 18-40 could give a very decent quality level. 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. Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? However most devices finally have some native h.265 decoding. The snippet above assumes that the input file is an MPEG2 stream. rev2023.3.1.43269. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Currently focused on React, Next.js, Gatsby. Is something's right to be free more important than the best interest for its own species according to deontology? ac3 should give you a 15%+ boost in speed. 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. This uses the native FFmpeg AAC encoder, but under AAC you will find info about more options. Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. Additionally to the previously mentioned arguments, ffmpeg VP9 and H265 codecs accept -crf flag . Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git 18 slow 68.298806 0.96016 Also, I find it much easier to share single ffmpeg commands across the team instead of showing where to click things in Handbrake. However, there is still a solution. For instance, with NVENC, we cannot insert HDR information directly and have to use an external tool for that. 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. Should have been already almost completed in all its parts! Asking for help, clarification, or responding to other answers. Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! The default is 28, and it should visually correspond to libx264 video at CRF 23, but result in about half the file size. 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. 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. Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions. Asking for help, clarification, or responding to other answers. Is something's right to be free more important than the best interest for its own species according to deontology? The number of distinct words in a sentence. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. So what *is* the Latin word for chocolate? By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . Strange that the video playback stops if the transcoder gets too far ahead, reaching its buffer limit, on the audio track only? 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. x265 CRF 28 is supposed to be equivalent to x264 CRF 23. There aren't some commercial products based on x265 nowadays? The short answer to the deviation from expected performance is that x265 is still under "heavy development". H265 Settings exclusive to H.265/HEVC encoding. 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. Not the answer you're looking for? Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. You get to choose the bitrate. Introducing FastFlix AV1 encoder GUI and more! 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? When it comes to bitrates, ensure that your desired values are set via the -b:v, -maxrate:v and -bufsize:v options. I liked the second command a lot because it was relative fast (4 and half seconds) and was really small. Really awesome! I want a setting that I can use on any incoming 4K HDR video I buy. 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. Aka a old movie with lots of film grain will need a lot higher bitrate than a modern action / adventure move, which will itself needs a lot higher than an animation. The one advantage of hevc_videotoolbox over libx265 is that it supports encoding videos in H265 with alpha channel. The real question is HDR. 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? (Well get to that later.). Also that I always recommend crf over hard bitrate/filesize because it is really source dependent for saving the proper amount of quality. What is the potential range for a good CRF value? So lets get a little more apples to apples. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. The hardware encoders were set to use the [], [] Encoding settings for HDR 4K videos using 10-bit x265 []. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. See FFmpeg Wiki: H.264 for more info. The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! I personally think the extra 2500kbps for the large jump in minimum quality from CRF 24 to CRF 22 is a must. 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. hevc_nvenc option information. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Convert ffmpeg encoding from libx264 to h264_nvenc. The absolute path to the output file. *** ### Encode video as x265 HEVC 10bit. 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. 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. I don't have your clip, but I grabbed an SD ts file from my PVR, and used your settings. The SSIM result is done frame by frame, so we have to average them all together to see which is best overall. Encode new files to MP4 or MKV. This is best explained with an example. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? Also note that the highest marker on this chart is 0.98, compared the total average charts 0.995. Of course, these metrics aren't perfect but you can use them as a rough guide to establish equivalence. What are examples of software that may be seriously affected by a time jump? 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. See FFmpeg Wiki: H.265 for more info about those options. Think of video format as a container that defines file structure for carrying video and audio streams. It means there is less differences between the original and the compressed one. 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. 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. The most widespread scenario for this one is scale. Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? The difference between the input and the output is practically non-visible for 1080p videos. How to increase the number of CPUs in my computer? It is faster by two orders of magnitude than libx265, but has some drawbacks. I did three CRF videos first, at 22, 20, and 18, then using their resulting bitrates created three ABR videos. , with NVENC, we get a little bit if you 're using any hardware-accelerated decoding mission-critical.
