ffmpeg best h265 settings

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. How can I recognize one? Acceleration without force in rotational motion? See HWAccelIntro for information on supported hardware H.265/HEVC encoders. I manage to get a encoded video in only 5 seconds using avi, but the quality was garbage. 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. If the source has HDR and I want to preserve it, it should be in 10-bit H.265. 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. is there a chinese version of ex. I tried to look up the documentation, but i simple don't have the multimedia background to understand it. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. Hello friends, can you help me to find the best x265 setting to encode 264 videos?sorry guys, i still new for ffmpeg. . ffmpeg creates large compressed files for tiny videos? (And if I ran these tests first, I would have even used slow for all the other testing!). Download the SSIM data as CSV. So lets take a step back and look at the lowest 1% of the frames. The snippet above assumes that the input file is an MPEG2 stream. Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. 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. H265 Settings exclusive to H.265/HEVC encoding. 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.

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? 1. 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. 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? Not bad, but we can do better! (Well get to that later.). Do not leave these blank. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. Dont be sad though, there is a solid alternative for iOS users. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. However, that does not mean smaller file size at the same CRF. 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. 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). Well well wishing well, that is even more definitive. rev2023.3.1.43269. Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. When the device you are going to watch it on doesnt support it. This is simply for videos using the BT.2020 color primaries. Just curious. Applications of super-mathematics to non-super mathematics. Ive got the right version of FFmpeg with libvmaf but am having a hard time getting the right CLI parameters. The CRF scales for x264 and x265 do not correspond. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Should I include the MIT licence of a library which I use from a CDN? At very low bitrates, however, x265 will indeed surpass x264, but at the levels of quality it does with default settings, you will be smudging a lot of fine grain and dark detail and the source would benefit from downscale DNR and pre-processing anyway. The normal wisdom is to use the the slowest you can stand for the encoding time. 1 When I transcode video to H265 with following command, I get a bitrate about 600K and the quality is almost the same as the original. The difference between the input and the output is practically non-visible for 1080p videos. So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. 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. ac3 should give you a 15%+ boost in speed. x265 CRF 28 is supposed to be equivalent to x264 CRF 23. How do I avoid objects having flickering edges when I encode a screen recording to mp4 using x264 and ffmpeg? Best settings for converting from h264 to hevc? 20 medium 66.884759 0.9598, 22 slow 67.187793 0.959167 3 seconds at the start is nothing as long as the movie plays fine. . There aren't some commercial products based on x265 nowadays? If libx265 is too slow use libx264 which is faster but file size will be bigger. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Predictable file sizes are a priority. Open a 2nd command line and encode another .ts at the same time. Privacy Policy. Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee. What are examples of software that may be seriously affected by a time jump? So lets take a step back and look at the lowest 1% of the frames.

Video Production Stack Exchange is a question and answer site for engineers, producers, editors, and enthusiasts spanning the fields of video, and media creation. Was Galileo expecting to see so many stars? Frameworks compete by optimizing network requests, images, and code to achieve a blazing-fast loading experience. There's a TLDR at the end. These gains will be most pronounced at resolutions of 1080p and higher. To learn more, see our tips on writing great answers. So, I'll link to the other answer that I posted. Pythons New Structural Pattern Matching! So using veryslow is more wise. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? Use the -x265-params lossless=1 option. But that's probably not what you want. It means there is less differences between the original and the compressed one. I may mix it up myself in this article, dont worry about the letter, just the numbers. Is email scraping still a thing for spammers. Does Cosmic Background radiation transmit heat?

Then I recently read YouTubes suggest guidelines for bitrates. 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 under. I dont use x265 for anything besides 4k HDR content. When you omit this option, ffmpeg uses -crf 32 for VP9 by . Note that hevc_nvenc will almost produce larger files than libx265 at a given quality because it not as efficient as an encoder. Thanks for contributing an answer to Stack Overflow! This is a good starting point on why these values matter. Also that I always recommend crf over hard bitrate/filesize because it is really source dependent for saving the proper amount of quality. (As a heads up h.265 is the specification, and x265 is encoder for it. as in example? Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. Why are non-Western countries siding with China in the UN? First things first, this is NOT a guide for Dolby Vision or HDR10. Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. 18 medium 67.552191 0.960256, 20 slow 67.835845 0.959723 If so, what would the best solution? The short answer to the deviation from expected performance is that x265 is still under "heavy development". 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). But x265 is not yet as mature in its development as x264, so take that CRF equivalence with a pinch of salt. 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. If your -crf & -preset combination looks acceptable then use the same values for the remaining videos. Also h264 is faster to encode that h265, but again it will impact quality. I have a raw footage and the quality of details of h264 with same CRF setting looks better than h265. Making statements based on opinion; back them up with references or personal experience. If it doesnt have HDR, the time to encode it doesnt make sense to me as it will take over twice as long vs H.264. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. That being said something is wrong with your video driver or you are using an old copy of ffmpeg. Thanks for contributing an answer to Stack Overflow! 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. 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. It is less efficient in terms of optimization and does not have Constant Quality mode (-crf) and presets we used in the previous example. Code Calamity 2023. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Scroll down to the bottom to see notes on the performance impact of presets with this particular encoder. By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . If we run the command above, it compresses the video down to 542 KB. Video and audio streams inside these containers are multimedia data encoded with codec. Not sure if theyre agnostic of resolution. Here is the order in which you have to pass arguments to FFmpeg: (b). There is only one time to not use it. 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). A home for professional coders articles, opinions and ideas. - Code Calamity, Animated AVIF is finally coming to Firefox, AMD improves video encoding yet again! 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 By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ? 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. Theoretically Correct vs Practical Notation. Also note that the highest marker on this chart is 0.98, compared the total average charts 0.995. Most time effective web format for converting h.265, The open-source game engine youve been waiting for: Godot (Ep. rev2023.3.1.43269. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. Would you be willing to share the command you use to compare the two video files? How to make PNG video render into 10bit h.264 matroska/avi file? RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless. H264 is very popular but much less optimized than VP9 or H265. Your inputs are already H.265/HEVC, so you can simply mux them into MP4 without needing to re-encode. Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? *** CRF 20-23 for most 1080p videos is enough. Super User is a question and answer site for computer enthusiasts and power users. Epic! How can I use CRF encoding with nvenc in ffmpeg? Those other encoders might be better - I haven't studied that PDF closely. Making statements based on opinion; back them up with references or personal experience. Is there a more recent similar source? So, if generally the CRF of h265 are "better" qualitatively speaking than the x264 ones how is possible that the encode results of x265 is worst than x264 with same CRF ? 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. Okay, okay, lets back up a step and look at the bottom 1% again as well. Making statements based on opinion; back them up with references or personal experience. Introducing FastFlix AV1 encoder GUI and more! See FFmpeg Wiki: H.264 for more info. 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. Put simply, the closer the result is to 1 the better. Think of video format as a container that defines file structure for carrying video and audio streams. -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. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? 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). 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. Create an account to follow your favorite communities and start taking part in conversations. Thanks @szatmary. Consider your encoding workflow and adjust as necessary. It only takes a minute to sign up. The Compilation Guides show you how to do that. Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git Is something's right to be free more important than the best interest for its own species according to deontology? Maybe something more visible at lower bitrates? Through some experimentation I found that I personally never can really see a difference between anything lower than 22 using a Slow present. As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). Does Cosmic Background radiation transmit heat? Encode new files to MP4 or MKV. 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. However, Im really only dealing with 1080p rips Curious if you have any data on the difference between Medium and Slow settings at 1080p? 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. 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. Antn Garcia. Sorry for the long post. CRF affects the quality. But that impacts quality so you will need to test to see what quality is acceptable. Viewing options The SSIM result is done frame by frame, so we have to average them all together to see which is best overall. I use the monochrome12 profile. And since you're on Windows, you may want to remove the shell escapes \ above as I'm writing this from a Unix box testing the command above. 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). There is currently a serious lack of data on compressing 4K HDR videos out there, so I took it upon myself to get learned in the ways of the x265 encoding world. 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. Can I use a vintage derailleur adapter claw on a modern derailleur. Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. 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. Do you think for H.265 but with 1080p and less content that all of what youve posted here would still be applicable or do you think its only for 4k content? Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. 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. (c). 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. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. Would the reflected sun's radiation melt ice in LEO? Why does Jesus turn to the Father to forgive in Luke 23:34? x265 uses CRF 18 by default. When you omit this option, ffmpeg uses -crf 32 for VP9 by default. Great explanation. But the quality is not as good as expected. A few interesting options for us are: libvpx-vp9 - which is used be default when you convert to WebM using VP9 codec, libx265 - for H265 code and mp4 container, hevc_videotoolbox - for H265 with a hardware acceleration. For local resources (on an accessible filesystem), the absolute file path is needed. 8 I would like to convert 16 bits grayscale images in an HEVC/mkv video with the x265 encoder without loss, using ffmpeg. If you are encoding to x264 or x265, encode to 10-bit if your devices support it. Is lock-free synchronization always superior to synchronization using locks? If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? In our case it is 3840px width. When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. libvpx-vp9 has the option -deadline which accepts following values: Time to switch to H265 and libx265. Maybe my setup isn't the best: I'm using ffmpeg for transcoding and vlc for review the videos, then i copy the screen content and compare the screens on a program like photoshop. The open-source game engine youve been waiting for: Godot (Ep. as in example? 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. 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. How did Dominion legally obtain text messages from Fox News hosts? Here is the order in which you have to pass arguments to FFmpeg: (a). I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). I tried to a post a total comment but got a mess. Really awesome! 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. ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv 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. Should the results be the same, relatively? Adapt as necessary to your encoding requirements. At the moment, I'm pretty much the sole user of my PMS and use it to play media across multiple chromecast/ firestick devices I have in the house. How did StorageTek STC 4305 use backing HDDs? 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. This is why the duplicate flag has been declined.

What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? 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. Any idea what might cause this? You can speed up and slow down encoding ruins presets. 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. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. Press question mark to learn the rest of the keyboard shortcuts. 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.
