ffmpeg best h265 settings

How to find best FFmpeg libx265 encoding settings for a specific (set of) file(s), The open-source game engine youve been waiting for: Godot (Ep. 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. As a bonus you can use the following nice shell script below that can create for you optimized video in VP9 and H265 with a single command. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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? As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more).

Now this is an apples to oranges comparison. ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv So I had to ask myself: To find out I would need a lot of comparable data. rev2023.3.1.43269. Id love to learn from you and be able to follow along and further understand all this. Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git if you don't, the encoder will choose on for you. 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Which is very similar to others results as well, so Im personally sticking too it. 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. What are some tools or methods I can purchase to trace a water leak? Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. 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. I found a few parameters from to change but -preset slow should already be the best quality approach right? The slow preset was used as it was determined to be an ideal choice in previous tests. Acceleration without force in rotational motion? You can also download a static build, all of which bundle libx265. I have a raw footage and the quality of details of h264 with same CRF setting looks better than h265. The number of distinct words in a sentence.

Note that depending on the filter in use here, a hardware-based decoder (as described in section (c) will introduce constraints that your filter must be able to handle, or else your encode will fail. as in example? But that's probably not what you want. For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. Anything from 18-40 could give a very decent quality level. Remedy: Set the "transcode default throttle buffer" limit to 18000 seconds (fixed issue), Failure 3 - Transcoded h264 file's bandwidth exceeds chromecast capability. 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. Connect and share knowledge within a single location that is structured and easy to search. Connect and share knowledge within a single location that is structured and easy to search. PTIJ Should we be afraid of Artificial Intelligence? Then I recently read YouTubes suggest guidelines for bitrates. I wanted to thank you for all this great work youve done on these articles.

Learn more about Stack Overflow the company, and our products. It is less efficient in terms of optimization and does not have Constant Quality mode (-crf) and presets we used in the previous example. Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions. Currently focused on React, Next.js, Gatsby. Sorry for the long post. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? In this data set, slow is the clear winner in multiple ways. For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. Not bad, but we can do better! . For some videos, you can try using the low resolution option, but on retina screens, it could lead to a blurry picture. However, there is still a solution. Just copy my settings and youre done!You can view the \"Step By Step\" instructions on The Webernets Website - https://www.thewebernets.com/2021/02/06/quick-easy-best-optimal-settings-for-handbrake-convert-dvd-video-to-h-265-hevc-mac-windows-linux/Lots of interesting information on the H.265 Codec here - https://x265.readthedocs.io/en/3.1/index.html Any idea what might cause this?

What is the potential range for a good CRF value? is it worth to spend more time to encode slower preset? Because if every frame was that good, we shouldnt need more than 6Mbps x265 or 10Mbps x264 4K video. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Is Koestler's The Sleepwalkers still well regarded? It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. Is this the best possible solution, or is there a better way of doing this? 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. FFmpeg best settings to encode Blu-Ray. Pythons New Structural Pattern Matching! The webm was quite small, but take many times the amount of time that mp4 took. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? 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 you look at the PDF I linked in the last comment, there are many encoders out there - most proprietary. Handbrake 1.2.2. 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. 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 something's right to be free more important than the best interest for its own species according to deontology? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. 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. 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. However, CRF shows its true edge on the lowest 1%, easily beating out ABR at every turn. Is there a more recent similar source? All Rights Reserved. Adapt as necessary to your encoding requirements. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. 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. PTIJ Should we be afraid of Artificial Intelligence? *** CRF 20-23 for most 1080p videos is enough. Has Microsoft lowered its Windows 11 eligibility criteria? Famous codecs are H264, H265, and VP8/9. 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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Please do not post the same answer to multiple questions. Older versions must use -x265-params keyint=1. Use CRF 23+ for videos in 4K. Have you seen the h264 & h265 pages? Press J to jump to the feed. Also note that the highest marker on this chart is 0.98, compared the total average charts 0.995. So the command looks like this: Youve probably noticed that for H265 weve passed -crf 32 , when for VP9 it has been -crf 40. First thing I did was to chop out a minute segment and promptly remove the HDR. The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. For H265, we need to learn some more extra options. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? 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. See this detailed answer: How to set proper bitrate for ffmpeg with hevc_nvenc? If the same information really answers both questions, then one question (usually the newer one) should be closed as a duplicate of the other. I mainly use Handbrake now use ffmpeg because I learned Handbrake only has a 8-bit internal pipeline. Asking for help, clarification, or responding to other answers. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? 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. Asking for help, clarification, or responding to other answers. What you want is a min quality level at resulting in a variable bit rate. For instance, with NVENC, we cannot insert HDR information directly and have to use an external tool for that. What does a search warrant actually look like? Epic! How to increase the number of CPUs in my computer? 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. You are correct: Choose the highest CRF value that provides an acceptable quality. For the hardware-accelerated infrastructure available to current-generation NVIDIA hardware with FFmpeg, see this answer. The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! Of course, these metrics aren't perfect but you can use them as a rough guide to establish equivalence. 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. 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. This is a good starting point on why these values matter. ffmpeg is a CLI tool and it has a lot of options that is nice to know. ***### 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.

I tried to look up the documentation, but i simple don't have the multimedia background to understand it. Thank you very much. I use the monochrome12 profile. 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. and our Antn Garcia. Video Production Stack Exchange is a question and answer site for engineers, producers, editors, and enthusiasts spanning the fields of video, and media creation. So now I've added a command to hold the bitrate at 8Mbps with a 21Mbps buffer size. Also, I find it much easier to share single ffmpeg commands across the team instead of showing where to click things in Handbrake. Those other encoders might be better - I haven't studied that PDF closely. Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. 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.

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. A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. 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. As with CRF, choose the slowest -preset you can tolerate, and optionally apply a -tune setting. What CRF or settings I should choose for h265 in order to achieve a similiar quality of h264? How do I avoid objects having flickering edges when I encode a screen recording to mp4 using x264 and ffmpeg? This topic can be confusing, so it's important to learn the difference. When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. This uses the native FFmpeg AAC encoder, but under AAC you will find info about more options. See HWAccelIntro for information on supported hardware H.265/HEVC encoders. Then, using that information, proceed to the next step. To learn more, see our tips on writing great answers. Open a 2nd command line and encode another .ts at the same time. 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. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. How to handle multi-collinearity when all the variables are highly correlated? Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. Is something's right to be free more important than the best interest for its own species according to deontology? Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. Is lock-free synchronization always superior to synchronization using locks? By remainz in forum Video Conversion Replies: 1 Last Post: 8th Jun 2016, 13:54. If so, what would the best solution? You can also download a static build, all of which bundle libx265. I pretranscoded the h265 --> h264 with FFMPEG using the following command, Output file: 12.1 Mbps 1080p h264 7.1 AAC mkv. Not the answer you're looking for? To learn more, see our tips on writing great answers. 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. Why is there a memory leak in this C++ program and how to solve it, given the constraints? Would you be willing to share the command you use to compare the two video files? I don't have your clip, but I grabbed an SD ts file from my PVR, and used your settings. Although I've been using Plex for years, my setup is far inferior to most of the people on this forum. It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. Visit the Trac open source project athttp://trac.edgewall.org/, Last modified on Oct 5, 2021, 11:32:18 AM. hevc_videotoolbox is a macOS-specific library that gives native hardware acceleration for H265 encoding. 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. You can verify lossless encoding by looking for x265 [info]: lossless compression ratio in the console output from your encoding command, or refer to the hash demuxer for verification. See FFmpeg Wiki: H.265 for more info about those options. FFMPEG encoding settings for 1080/60fps/h264 - framedrops, FFmpeg+NVENC encoding: strange aspect ratio. The most widespread scenario for this one is scale. The bitrates are as expected, the higher quality it gets the more bitrate it will need. )Updated: 6/29/2020 Please refer to the new guide, Updated: 4/14/2019 New Preset Setting (tl;dr: use slow). 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. 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. Something wrong with reddit clipboard. Theoretically Correct vs Practical Notation. I started with a 4K HDR example video. ffmpeg -c:v libx265 -preset fast -crf 28 -tag:v hvc1 -c:a eac3 -b:a 224k -i <source> <target>. And embedding it to the project with this html getting the best possible result. 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. Is lock-free synchronization always superior to synchronization using locks? Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. 28 and 23 are the default CRF values of x265 and x264 respectively, hence the supposed equivalence. The absolute path to the output file. Pretty new to this but I have one questions I cant seem to read up on, If I have a 10 bit 4k movie and I use the H265 AMD VCE video encoder, would I lose the 10 bit with the new conversion? Do people usually encode with 20+ for 1080p? The short answer to the deviation from expected performance is that x265 is still under "heavy development". The real question is HDR. I have read that previously, Chromecast used to limit playback at 11 Mbps. H264 is very popular but much less optimized than VP9 or H265. https://www.youtube.com/watch?v=bzgFL-gNF9g. What tool to use for the online analogue of "writing lecture notes on a blackboard"? how to use FFMPEG to transcode h264 to h265 on Ubuntu 12.04? Start by understanding the encoder's options. (b). Find centralized, trusted content and collaborate around the technologies you use most. The Compilation Guides show you how to do that. Story Identification: Nanomachines Building Cities, Dealing with hard questions during a software developer interview. So lets take a step back and look at the lowest 1% of the frames. Jordan's line about intimate parties in The Great Gatsby? Profiles can be set via the -profile:v option, similar to libx264. Not the answer you're looking for? FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. Declare your inputs. You need to download the model you want to use (vmaf_4k_v0.6.1.pkl and vmaf_4k_v0.6.1.pkl.model in my case) from https://github.com/Netflix/vmaf/tree/master/model. Thanks for contributing an answer to Super User! 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. When you omit this option, ffmpeg uses -crf 32 for VP9 by . Thanks for contributing an answer to Stack Overflow! Then in three years H.266 / VVC toolsets will probably be popping up. For local resources (on an accessible filesystem), the absolute file path is needed. On the section of video I chose, x264 needed considerably more bitrate to achieve the same score. The one advantage of hevc_videotoolbox over libx265 is that it supports encoding videos in H265 with alpha channel. It states that for 4K videos with x265 they suggest a Constant Rate Factor (CRF) encoding in the range of 22-28 (the larger the number the lower the quality). Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. I'm using my FFMPEG with the suport of my GPU (NVENC) to convert files from my satelite receiver (SD, mpeg2 .TS-Files) into h264 .mp4-files. Can I use a vintage derailleur adapter claw on a modern derailleur. Depends on the encoder, the ffmpeg one I dont think supports 10 bit, but VCEEncC does. If you wanted to target 4 Mbps you'd want to be using veryslow for sure. Optionally, insert a filter. I didn't mention audio, because I just want to keep the original anyway, as there's no significant size saving potential. 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. Ive specified it to 3x the 8Mbps (so 21M). To some, including myself, it could be worth the extra 4000kbps jump from CRF 22 to CRF 20. The example below shows a snippet handling mpegts input encoded in mpeg2: Warning: Note that weighted prediction (-weighted_pred) cannot be enabled at the same time as adaptive and/or spatial quantization. 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. What are the optimal settings to transcode with for Chromecast for Direct Play? In this test, I encoded all videos with ffmpeg using the default presents. Ackermann Function without Recursion or Stack. I tried encoding some 4K HDR files using Handbrake and they look washed out. Is email scraping still a thing for spammers. We have some hard date, lets use it. All tests run using one of the animations we've made for a recent project. Connect and share knowledge within a single location that is structured and easy to search. Well well wishing well, that is even more definitive. See FFmpeg Wiki: H.264 for more info. The normal wisdom is to use the the slowest you can stand for the encoding time. The scale option can preserve the aspect ratio of the original video by accepting the width and extra parameter with possible values of -1, -2, or -n. -2 value guarantees that the resulted output resolution will be even. Hmm interesting, may i ask why this scales doesn't correspond? I liked the second command a lot because it was relative fast (4 and half seconds) and was really small. Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. You can remove this scale=858:482: from my scripts. For everyone else, you can follow instruction on the site. 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. 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? Do not leave these blank. Centering layers in OpenLayers v4 after layer loading. You could probably lower those a little bit if you want, too. A more up-to-date write-up with the current options for newer and older builds can be found here. It seems like a flaw in the encoder; it performs predictably in every other respect, but it needs (for example) -b:v 4M for a 720p file or -b:v 8M for 1080p. 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. Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. So lets take a step back and look at the lowest 1% of the frames. 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. I dont use x265 for anything besides 4k HDR content. Should have been already almost completed in all its parts!
