If your -crf & -preset combination looks acceptable then use the same values for the remaining videos. Really awesome! Keep in mind Im talking exclusively of x264 level 5.1+. For two-pass, you need to run ffmpeg twice, with almost the same settings, except for: For libx265, the -pass option (that you would use for libx264) is not applicable. In our case it is 3840px width. Asking for help, clarification, or responding to other answers. By Edgewall Software 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. Modern video codecs can deliver excellent quality while preserving a very reasonable size. Even though it does cost double the time of medium it really delivers in the quality department. TLDR: FFMPEG transcode 1080p h265/HEVC 7.1 5Mbps--> h264 12Mbps (31.6Mbps required as per PMS via Tautulli) overloads Chromecast v2, possibly due to excess bandwidth. And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy.

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. Or for GPU-based encoding, which is much faster, but . 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. Thank you, I did look at the wiki (the H.264 page as well, which is more elaborate), I just wanted to make sure I'm not missing anything else that would be worth paying attention to. FFmpeg: For NVENC, what is a concurrent surface? Thanks for contributing an answer to Stack Overflow! ffmpeg - Read raw Data instead of converting to different Format, What is the fastest method to compress videos before sending in React Native Chatting app. As always, start by specifying a preset. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. Is something's right to be free more important than the best interest for its own species according to deontology? If you like I"d be happy to test one of your .ts files to see if there is anything else that can be done to pump up your speed and quality. But that's probably not what you want. Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? Put simply, the closer the result is to 1 the better. 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. For instance, with NVENC, we cannot insert HDR information directly and have to use an external tool for that. I tried to a post a total comment but got a mess. 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. I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Not the answer you're looking for? Anything from 18-40 could give a very decent quality level. 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 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. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Additionally to the previously mentioned arguments, ffmpeg VP9 and H265 codecs accept -crf flag . What's the difference between a power rail and a signal line? Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. Was Galileo expecting to see so many stars? The number of distinct words in a sentence, Torsion-free virtually free-by-cyclic groups. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? Making statements based on opinion; back them up with references or personal experience. What is the potential range for a good CRF value? Should I include the MIT licence of a library which I use from a CDN? 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). 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 bad, but we can do better! By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 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. This is a good starting point on why these values matter. Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. -vf - the option for passing filters to ffmpeg. PTIJ Should we be afraid of Artificial Intelligence? It only takes a minute to sign up. So lets take a step back and look at the lowest 1% of the frames. Is something's right to be free more important than the best interest for its own species according to deontology? (g). Should have been already almost completed in all its parts! Choose the highest CRF value that provides an acceptable quality. 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. 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. Then I recently read YouTubes suggest guidelines for bitrates. 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. 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. You can also download a static build, all of which bundle libx265. Use CRF 23+ for videos in 4K. Suspicious referee report, are "suggested citations" from a paper mill? You can indicate this by, i can link the answer to the other question. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. x265 CRF 28 is supposed to be equivalent to x264 CRF 23. 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. You can also download a static build, all of which bundle libx265. CRF is the best of both worlds. FFmpeg best settings to encode Blu-Ray. Have you seen the h264 & h265 pages? How can I use CRF encoding with nvenc in ffmpeg? So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. Please do not post the same answer to multiple questions. I started with a 4K HDR example video. Choose the slowest preset that you have patience for. Theoretically Correct vs Practical Notation. It is less efficient in terms of optimization and does not have Constant Quality mode (-crf) and presets we used in the previous example. Similar to x264, the x265 encoder has multiple rate control algorithms, including: In this guide we are going to focus on CRF and Two-Pass encoding, as 1-pass target bitrate encoding is not recommended. ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv It is not a royalty-free codec - perhaps, that is why the adoption rate is much less than of WebM's. 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). Jordan's line about intimate parties in The Great Gatsby? Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. Not the answer you're looking for? Hope that helps, thanks for asking and happy to help! Hmm interesting, may i ask why this scales doesn't correspond? As with CRF, choose the slowest -preset you can tolerate, and optionally apply a -tune setting. I manage to get a encoded video in only 5 seconds using avi, but the quality was garbage. At what point of what we watch as the MCU movies the branching started? 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. Would the reflected sun's radiation melt ice in LEO? Can I use a vintage derailleur adapter claw on a modern derailleur. Quality degradation is more prominent with higher thread counts in constant bitrate modes and near-constant bitrate mode called VBV (video buffer verifier), due to increased encode delay. Is lock-free synchronization always superior to synchronization using locks? Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. So I had to ask myself: To find out I would need a lot of comparable data. Adapt as necessary to your encoding requirements. For everyone else, you can follow instruction on the site. @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. For the llhp and llhq presets, as well as other presets in use, you can also override the in-built rate-control methods by passing the -rc:v arguments as exposed by the encoder options. If you are encoding to x264 or x265, encode to 10-bit if your devices support it. There are two most popular tools for video optimization -Handbrake andffmpeg. 1. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Asking for help, clarification, or responding to other answers. Handbrake has a GUI, and it makes it much easier to use; however, using ffmpeg is a more flexible option in case you want to render videos with alpha(transparent) channels or use hardware acceleration that speeds up compression a lot. Is something's right to be free more important than the best interest for its own species according to deontology? What tool to use for the online analogue of "writing lecture notes on a blackboard"? 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. So using veryslow is more wise. Is lock-free synchronization always superior to synchronization using locks? (And if I ran these tests first, I would have even used slow for all the other testing!). Find centralized, trusted content and collaborate around the technologies you use most. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? 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. Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and If you look at the PDF I linked in the last comment, there are many encoders out there - most proprietary. x265 uses CRF 18 by default. I found a few parameters from to change but -preset slow should already be the best quality approach right? In this test, I encoded all videos with ffmpeg using the default presents. 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. *** ### Encode video as x265 HEVC 10bit. Thanks @szatmary. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? 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. Encode some random segments from typical inputs. rev2023.3.1.43269. 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. It is faster by two orders of magnitude than libx265, but has some drawbacks. 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. Open a 2nd command line and encode another .ts at the same time. ), In pass 1, you can leave audio out by specifying, P. Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. By default, this is disabled, and it is generally not required to set a tune option. 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. x265 uses CRF 18 by default. To some, including myself, it could be worth the extra 4000kbps jump from CRF 22 to CRF 20. 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. I want a setting that I can use on any incoming 4K HDR video I buy. To learn more, see our tips on writing great answers. 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. Making statements based on opinion; back them up with references or personal experience. Connect and share knowledge within a single location that is structured and easy to search. Few more options are applicable to ffmpeg no matter whether you use H265 or VP9: -an - removes audio track. 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 comparing to standard 4.1 profile than yes, x265 outperform it in almost any metric. For more information, please see our 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 Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? The short answer to the deviation from expected performance is that x265 is still under "heavy development". Using AVIF and HEIF images with Python / PIL, https://gist.github.com/cdgriffith/20c8bbb220a05358da47710e2a512308, https://github.com/Netflix/vmaf/tree/master/model, https://i0.wp.com/codecalamity.com/wp-content/uploads/2019/04/4K_preset_avg_extra.png?ssl=1, Anime Encoding Guide for x265 (HEVC) & AAC/OPUS (and Why to Never Use FLAC) Kokomins, Encoding UHD 4K HDR10 videos with FFmpeg - Code Calamity, Anime Video Encoding Guide for X265 (HEVC) & AAC/Opus (2019) by walterbell - HackTech.news, Hardware Encoding 4K HDR10 Videos? For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. Adding -crf 0 is not required. Cookie Notice So what *is* the Latin word for chocolate? So where does that show up on our chart? If the source has HDR and I want to preserve it, it should be in 10-bit H.265. Epic! Why does Jesus turn to the Father to forgive in Luke 23:34? 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). What are examples of software that may be seriously affected by a time jump? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. But based on just the average, slow was the obvious choice, as even bumping up the CRF from 18 to 16 didnt match the quality. Then, using that information, proceed to the next step. See a list of available x265 profiles. Those other encoders might be better - I haven't studied that PDF closely. You can remove this scale=858:482: from my scripts. 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. Ive got the right version of FFmpeg with libvmaf but am having a hard time getting the right CLI parameters. So lets take a step back and look at the lowest 1% of the frames. Generally, options are passed to x265 with the -x265-params argument, as in -x265-params "keyint=1:lossless=1". 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 Getting ffmpeg with libx265 support ffmpeg needs to be built with the --enable-gpl --enable-libx265 configuration flags and requires x265 to be installed on your system. You can change this by adding -b:v option to ffmpeg. Thank you!! from the chart SSIM difference is very low. 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. In this case, you are using two different encoders, so you get different bitrates. For some videos, you can try using the low resolution option, but on retina screens, it could lead to a blurry picture. I hope you found this information as useful as I did, if you have any thoughts or feedback please let me know! Privacy Policy. Video Production Stack Exchange is a question and answer site for engineers, producers, editors, and enthusiasts spanning the fields of video, and media creation. Depends on the encoder, the ffmpeg one I dont think supports 10 bit, but VCEEncC does. In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. Thanks for contributing an answer to Video Production Stack Exchange! Dealing with hard questions during a software developer interview. But the quality is not as good as expected. Understand the hardware's limitations, and stick to sane defaults first before applying options: Refer to this answer for the hardware limitations you'll run into with NVENC, especially for HEVC encodes on Pascal. Now this is an apples to oranges comparison. I tried encoding some 4K HDR files using Handbrake and they look washed out. Another flag you can pass is -movflags faststart. Connect and share knowledge within a single location that is structured and easy to search. How to increase the number of CPUs in my computer? See HWAccelIntro for information on supported hardware H.265/HEVC encoders. Then in three years H.266 / VVC toolsets will probably be popping up. But that impacts quality so you will need to test to see what quality is acceptable. (f). Okay, okay, lets back up a step and look at the bottom 1% again as well. 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. 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. 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. ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless. 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. Press question mark to learn the rest of the keyboard shortcuts. Still, we get a good idea of where these show up. (Well get to that later.).

Unfortunately, the same can't be said about videos. Convert ffmpeg encoding from libx264 to h264_nvenc. All tests run using one of the animations we've made for a recent project. ffmpeg -c:v libx265 -preset fast -crf 28 -tag:v hvc1 -c:a eac3 -b:a 224k -i <source> <target>. Choose a CRF. For H265, we need to learn some more extra options. 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. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Thank you very much. Pythons New Structural Pattern Matching! However, I head that this cap was removed. I will make a few tests with h264. 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). Jordan's line about intimate parties in The Great Gatsby? Could the loss of quality be caused by VLC and its experimental support in deconding h265? The command I use boils down to ffmpeg.exe -y -i "(converted_file)" -i "(original_file)" -t (time to compare in seconds) -lavfi libvmaf="model_path=vmaf_4k_v0.6.1.pkl:log_path=details.txt;[0:v][1:v]ssim=1" -report -f null -\n.

But that is all hypothetical. hevc_videotoolbox is a macOS-specific library that gives native hardware acceleration for H265 encoding. 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. Viewing options Does Cosmic Background radiation transmit heat? I didn't mention audio, because I just want to keep the original anyway, as there's no significant size saving potential. Does With(NoLock) help with query performance? The open-source game engine youve been waiting for: Godot (Ep. Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. It means there is less differences between the original and the compressed one. 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.
