ffmpeg best h265 settings

Not bad, but we can do better! Use CRF 23+ for videos in 4K. I tried to look up the documentation, but i simple don't have the multimedia background to understand it. Frameworks compete by optimizing network requests, images, and code to achieve a blazing-fast loading experience. It is faster by two orders of magnitude than libx265, but has some drawbacks. FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and Adapt as necessary to your encoding requirements. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Keep in mind that is while still being lesser quality than CRF 18 - Slow. FFmpeg: For NVENC, what is a concurrent surface? 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. 22 medium 65.979806 0.959182. (f). Thankfully there is a simple answer. Between H.264 and H.265, from what I've read the difference is about 30%, which is an impressive improvement at that point, considering how efficient H.264 already was, but from a practical standpoint it's too small to justify a systematic conversion just for the sake of saving a few gigabytes (or even hundreds of gigabytes - you may end up If so, what would the best solution? ffmpeg creates large compressed files for tiny videos? Is email scraping still a thing for spammers. x265 uses CRF 18 by default. rev2023.3.1.43269. I've gone through this sub and tried to improve my transcodes, but I'm still not 100% there. Would the reflected sun's radiation melt ice in LEO? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. How to increase the number of CPUs in my computer? 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). Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. I wanted to thank you for all this great work youve done on these articles. In this case, you are using two different encoders, so you get different bitrates.

Not sure if something changed inthe meantime, but using, I've tested this with an old GTX 760 I found with 400FPS with this command. Also h264 is faster to encode that h265, but again it will impact quality. I see, so because of this heavy development status even if I decide to move from ffmpeg and libx265 to another encoder the results will not change so much right? 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. Is this enough, or should I take some other things into consideration as well? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. You can indicate this by, i can link the answer to the other question. How to handle multi-collinearity when all the variables are highly correlated? The webm was quite small, but take many times the amount of time that mp4 took. 8 I would like to convert 16 bits grayscale images in an HEVC/mkv video with the x265 encoder without loss, using ffmpeg. Connect and share knowledge within a single location that is structured and easy to search. Encode some random segments from typical inputs. 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). They have some good detail on what things mean. ac3 should give you a 15%+ boost in speed. So lets take a step back and look at the lowest 1% of the frames. Keep in mind Im talking exclusively of x264 level 5.1+. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? When it comes to bitrates, ensure that your desired values are set via the -b:v, -maxrate:v and -bufsize:v options. This topic can be confusing, so it's important to learn the difference. Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. Acceleration without force in rotational motion? There is no such thing as "proper bitrate". 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. q Every modern browser on desktop and mobile supports it, except Safari on iOS. 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. 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. See FFmpeg Wiki: H.265 for more info. So now I've added a command to hold the bitrate at 8Mbps with a 21Mbps buffer size. Thanks for contributing an answer to Super User! At what point of what we watch as the MCU movies the branching started? For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. It is well known between pros that SSIM and PSNR are not good measures or SUBJECTIVELY PERCEIVABLE quality. What would be the most time effective format and how to convert a raw h.265 video to it? Epic! For everyone else, you can follow instruction on the site. All tests run using one of the animations we've made for a recent project. The Compilation Guides show you how to do that. Choose the slowest preset that you have patience for. However, CRF shows its true edge on the lowest 1%, easily beating out ABR at every turn. Hmm interesting, may i ask why this scales doesn't correspond? *** CRF 20-23 for most 1080p videos is enough. ***### Encode video as x265 HEVC 10bit.ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv### Same as above, but as a two-pass x265 HEVC 10bit encode.ffmpeg -y -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=1 -an -f null /dev/null && \ffmpeg -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=2 -c:a copy "output".mkv.

Okay, okay, lets back up a step and look at the bottom 1% again as well. Why did the Soviets not shoot down US spy satellites during the Cold War? It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. If you wish to master the tool, you will have to learn how to use flags. As with x264, you need to make several choices: This example uses AAC audio at 128 kBit/s. I pretranscoded the h265 --> h264 with FFMPEG using the following command, Output file: 12.1 Mbps 1080p h264 7.1 AAC mkv. Is email scraping still a thing for spammers. (As a heads up h.265 is the specification, and x265 is encoder for it. Help with ffmpeg settings H265. Making statements based on opinion; back them up with references or personal experience. Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? 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. 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? First things first, this is NOT a guide for Dolby Vision or HDR10. Do not leave these blank. These gains will be most pronounced at resolutions of 1080p and higher. WebM is an open, royalty-free media file format designed for the web. Connect and share knowledge within a single location that is structured and easy to search.

But i don't think that I am doing it in the most effective way. Add it next to your -c:v h264_nvenc -c:a ac3 You should also be able to push 2 sessions. What's the difference between a power rail and a signal line? Theoretically Correct vs Practical Notation. Any idea what might cause this? If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. So lets get a little more apples to apples. ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv The number of distinct words in a sentence. Attempting to do so will result in encoder initialization failure. This is why the duplicate flag has been declined. Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. It can carry video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with theVorbisorOpusaudio codecs. I personally think the extra 2500kbps for the large jump in minimum quality from CRF 24 to CRF 22 is a must. Asking for help, clarification, or responding to other answers. See a list of available x265 profiles. But that impacts quality so you will need to test to see what quality is acceptable. So what *is* the Latin word for chocolate? When comparing to standard 4.1 profile than yes, x265 outperform it in almost any metric. Does ffmpeg really use my Graphics card to encode? ffmpeg -framerate 30 -i in.265 -i in.avi -c copy -map 0:v -map 1:a -video_track_timescale 1k fixed.mp4 Replace the framerate value with the true rate of the video.

(h). ffmpeg needs to be built with the --enable-gpl --enable-libx265 configuration flags and requires x265 to be installed on your system. The one advantage of hevc_videotoolbox over libx265 is that it supports encoding videos in H265 with alpha channel. Should have been already almost completed in all its parts! See FFmpeg Wiki: H.264 for more info. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? The open-source game engine youve been waiting for: Godot (Ep. Call up the appropriate video and audio encoders, and pass necessary arguments to them, such as mappings, bitrates, encoder presets, etc. This is simply for videos using the BT.2020 color primaries. I ran some quick tests this morning with a script I am using for a new version of this article using ffmpeg instead of Handbrake. Jordan's line about intimate parties in The Great Gatsby? Can I use a vintage derailleur adapter claw on a modern derailleur. Using video for animation with proper optimization is always better than GIF and sometimes outperforms native implementations. Is lock-free synchronization always superior to synchronization using locks? Additionally to the previously mentioned arguments, ffmpeg VP9 and H265 codecs accept -crf flag . Please do not post the same answer to multiple questions. What is interesting, is if we put CRF 16 - Medium encodings bitrate on this chart it would go shoot off the top at a staggering 15510kbps!

I used a three minute 4K HDR clip, using Handbrake to only modify which present was used. Optionally, insert a filter. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. Use CRF 23+ for videos in 4K. Find centralized, trusted content and collaborate around the technologies you use most. 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. 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. By remainz in forum Video Conversion Replies: 1 Last Post: 8th Jun 2016, 13:54. Centering layers in OpenLayers v4 after layer loading. There is only one time to not use it. Note that when using faster presets with the same target bitrate, the resulting quality will be lower and vice-versa. thank you, I'll try it now and feedback you later ^^, I use it to decrease scale. Definitely not for archiving. Those other encoders might be better - I haven't studied that PDF closely. The mode works exactly the same as in x264, except that maximum value is always 51, even with 10-bit support, so please read the H.264 guide for more info. Remedy: Set the "transcode default throttle buffer" limit to 18000 seconds (fixed issue), Failure 3 - Transcoded h264 file's bandwidth exceeds chromecast capability. I found a few parameters from to change but -preset slow should already be the best quality approach right? hevc_nvenc option information. Thanks @szatmary. Or for GPU-based encoding, which is much faster, but . and our Would you be willing to share the command you use to compare the two video files? A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. I dont use x265 for anything besides 4k HDR content. 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. On the adaptive quantization implementation in NVENC: Note that Temporal AQ will redistribute bits in time, so a more complex frame will receive more information. 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. When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. Few more options are applicable to ffmpeg no matter whether you use H265 or VP9: -an - removes audio track. Has Microsoft lowered its Windows 11 eligibility criteria? A home for professional coders articles, opinions and ideas. It only takes a minute to sign up. So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. Depends on the encoder, the ffmpeg one I dont think supports 10 bit, but VCEEncC does. 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.

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. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. You can speed up and slow down encoding ruins presets. The original was H.265 encoded with a .ts extension. The bitrates are as expected, the higher quality it gets the more bitrate it will need. How to increase the number of CPUs in my computer? Choose the highest CRF value that provides an acceptable quality. Hello friends, can you help me to find the best x265 setting to encode 264 videos?sorry guys, i still new for ffmpeg. 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 As with CRF, choose the slowest -preset you can tolerate, and optionally apply a -tune setting. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. Modern web development every year applies new standards for performance. Download the SSIM data as CSV. Thank you!! Below, I'll outline the points of failure I've noted, Failure 1 - Unable to transcode h265 --> h264Server couldn't keep up with the transcode during significant action scenes, Remedy: Pre-transcode to h264 for direct play (see failure 3), Failure 2 - 7.1 AAC transcodes to 7.1 EAC3 - playback stops when transcoder hits the 'throttle' limit. Making statements based on opinion; back them up with references or personal experience. Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. This uses the native FFmpeg AAC encoder, but under AAC you will find info about more options. When the device you are going to watch it on doesnt support it. is there a chinese version of ex. YouTubes suggest guidelines for bitrates. 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. )Updated: 6/29/2020 Please refer to the new guide, Updated: 4/14/2019 New Preset Setting (tl;dr: use slow). How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? -vf - the option for passing filters to ffmpeg. What does a search warrant actually look like? H265, a.k.a HEVC (High-Efficiency Video Coding), is a codec supported by Apple and shows the same 20-50% better efficiency than its H264 older brother. The Compilation Guides show you how to do that. But x265 is not yet as mature in its development as x264, so take that CRF equivalence with a pinch of salt. 1. Connect and share knowledge within a single location that is structured and easy to search. The SSIM result is done frame by frame, so we have to average them all together to see which is best overall. Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ? ffmpeg -i input.h265 -c copy -movflags +faststart output.mp4 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 ): ffmpeg -i input.h265 -c:v libx265 -crf 28 -preset medium -movflags +faststart output.mp4 Adjust -crf and -preset to your liking. CEO at Pixel Point and software engineer with 10+ years of web development experience. 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). However, I head that this cap was removed. 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. The jump from medium to slow is very significant in multiple ways.

But after even a basic compression it cuts down to 1MB. Powered by Trac 1.4.2 How can I use CRF encoding with nvenc in ffmpeg? If we run the command above, it compresses the video down to 542 KB. 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. The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. Asking for help, clarification, or responding to other answers. Well well wishing well, that is even more definitive. For some videos, you can try using the low resolution option, but on retina screens, it could lead to a blurry picture. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. Does Cosmic Background radiation transmit heat? Some popular examples of video formats are mp4, WebM, or MKV. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.
