Applications of super-mathematics to non-super mathematics. An addition to the previous comment. Thanks for contributing an answer to Stack Overflow! 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. You can list private options available in this encoder with ffmpeg -h encoder=libx265. How did StorageTek STC 4305 use backing HDDs? Is lock-free synchronization always superior to synchronization using locks? Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. Your mileage will definitely vary, based on your source content, filter chains in use, specific pltform configuration variables (such as your GPU and driver versions), etc. I tried to look up the documentation, but i simple don't have the multimedia background to understand it. 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 By default, this is disabled, and it is generally not required to set a tune option. The one advantage of hevc_videotoolbox over libx265 is that it supports encoding videos in H265 with alpha channel. The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! 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. Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? Libvorbis for audio seems slow. If so, what would the best solution? *** CRF 20-23 for most 1080p videos is enough. Reddit and its partners use cookies and similar technologies to provide you with a better experience. When it comes to bitrates, ensure that your desired values are set via the -b:v, -maxrate:v and -bufsize:v options. Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! As always, start by specifying a preset. If the source has HDR and I want to preserve it, it should be in 10-bit H.265. This is also all evolving, so next year the AV1 tools may be fast and user friendly enough to use that instead of H.265 for encoding. Does Cosmic Background radiation transmit heat? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. When you omit this option, ffmpeg uses -crf 32 for VP9 by . I use the monochrome12 profile. Additionally to the previously mentioned arguments, ffmpeg VP9 and H265 codecs accept -crf flag . Note that the preset selected has the greatest impact on throughput, followed by the preset options (such as the rate control method in use) that you can optionally override if desired. I have to use a separate comments for every statement. So what *is* the Latin word for chocolate? rev2023.3.1.43269. Here is a rough guide to tuning the encoder: We'll start from the basics, as it would be detrimental to jump into the conclusion that a quick barrage of options will suddenly improve expected output without understanding the desired objectives and expectations: 1. Then, using that information, proceed to the next step. How do I speed up the encoding? 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. 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). If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. This is a good starting point on why these values matter. I have read that previously, Chromecast used to limit playback at 11 Mbps. I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. To learn more, see our tips on writing great answers. Was Galileo expecting to see so many stars? 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. FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and is there a chinese version of ex. It is less efficient in terms of optimization and does not have Constant Quality mode (-crf) and presets we used in the previous example. 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? Encode new files to MP4 or MKV. 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. Cookie Notice (c). This method is generally used if you are targeting a specific output file size and output quality from frame to frame is of less importance. how to use FFMPEG to transcode h264 to h265 on Ubuntu 12.04? Even though it does cost double the time of medium it really delivers in the quality department. I believe that the last value of 31.6 Mbps is exceeding the capacity of the Chromecast v2. The open-source game engine youve been waiting for: Godot (Ep. Theoretically Correct vs Practical Notation. The most widespread scenario for this one is scale. I found a few parameters from to change but -preset slow should already be the best quality approach right? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Although I've been using Plex for years, my setup is far inferior to most of the people on this forum. This should work in your command line. - Code Calamity, Animated AVIF is finally coming to Firefox, AMD improves video encoding yet again! 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). The number of distinct words in a sentence. Here is the order in which you have to pass arguments to FFmpeg: (a). 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. I may mix it up myself in this article, dont worry about the letter, just the numbers. I mainly use Handbrake now use ffmpeg because I learned Handbrake only has a 8-bit internal pipeline. Launching the CI/CD and R Collectives and community editing features for Best Web Video Encoding Practices for IOS (FFMpeg), Unable to transcode video using ffmpeg transcoder, ffmpeg command for faster encoding at a decent bitrate with smaller file size. 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. 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. 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. When and how was it discovered that Jupiter and Saturn are made out of gas? Making statements based on opinion; back them up with references or personal experience. ***### 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. Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. Also that I always recommend crf over hard bitrate/filesize because it is really source dependent for saving the proper amount of quality. Attempting to do so will result in encoder initialization failure. Press question mark to learn the rest of the keyboard shortcuts. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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. FFmpeg best settings to encode Blu-Ray. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 22 medium 65.979806 0.959182. Note that hevc_nvenc will almost produce larger files than libx265 at a given quality because it not as efficient as an encoder. What is the potential range for a good CRF value? But after even a basic compression it cuts down to 1MB. 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. A home for professional coders articles, opinions and ideas. 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. Connect and share knowledge within a single location that is structured and easy to search. A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. 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. Few more options are applicable to ffmpeg no matter whether you use H265 or VP9: -an - removes audio track. If you wanted to target 4 Mbps you'd want to be using veryslow for sure. However, that does not mean smaller file size at the same CRF. See FFmpeg Wiki: H.264 for more info. 3 seconds at the start is nothing as long as the movie plays fine. Do not leave these blank. 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Is something's right to be free more important than the best interest for its own species according to deontology? 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 Profiles can be set via the -profile:v option, similar to libx264. CRF is the best of both worlds. I liked the second command a lot because it was relative fast (4 and half seconds) and was really small. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. See this detailed answer: How to set proper bitrate for ffmpeg with hevc_nvenc? 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. Really awesome! Every modern browser on desktop and mobile supports it, except Safari on iOS. 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 Acceleration without force in rotational motion? Through some experimentation I found that I personally never can really see a difference between anything lower than 22 using a Slow present. ffmpeg creates large compressed files for tiny videos? Viewing options By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. First things first, this is NOT a guide for Dolby Vision or HDR10. Asking for help, clarification, or responding to other answers. Here is the order in which you have to pass arguments to FFmpeg: (b). This topic can be confusing, so it's important to learn the difference. Use CRF 23+ for videos in 4K. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. Linking VCEEncC in the Settings panel of FastFlix is the easiest way to get started with it and will automatically put the required setting of --output-depth 10 to make it 10 bit. Even though others have tackled this issue, I wanted to use the same material I was already testing and make sure it held true with 4K HDR video. 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. Is email scraping still a thing for spammers. Create an account to follow your favorite communities and start taking part in conversations. ), In pass 1, you can leave audio out by specifying, P. Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. Call up the binary. Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. It means there is less differences between the original and the compressed one. This guide focuses on the encoder libx265 which can offer around 2550% bitrate savings compared to H.264 video encoded with libx264, while retaining the same visual quality. As I'm new to this, I tried doing some research and found that mostly it's about choosing the correct CRF and preset, so I am thinking it would be sufficient to write a script which iterates through these, creating samples which I could look at and decide what's the best option for a given (set of) video(s). Even if there is no sound in a file, there could be empty audio track information that will occupy some additional weight, so always use it for muted videos. Anything from 18-40 could give a very decent quality level. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? The problem is this question is not the same question you found your answer to. 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. FFMPEG gop settings. Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. I dont use x265 for anything besides 4k HDR content. 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 pretranscoded the h265 --> h264 with FFMPEG using the following command, Output file: 12.1 Mbps 1080p h264 7.1 AAC mkv. Predictable file sizes are a priority. 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. libvpx-vp9 has the option -deadline which accepts following values: Time to switch to H265 and libx265. 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. Please do not post the same answer to multiple questions. Keyframes need more data then other frame types to avoid pulsing poor quality keyframes. Note that when using faster presets with the same target bitrate, the resulting quality will be lower and vice-versa. 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. FFmpeg commands I using are the following: I used 30 as CRF for testing purposes because the artifacts are more visible :). In our case it is 3840px width. (if you go higher than 4.1 preset). @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. Ive got the right version of FFmpeg with libvmaf but am having a hard time getting the right CLI parameters. 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. By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . 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. Also, I find it much easier to share single ffmpeg commands across the team instead of showing where to click things in Handbrake. 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. Why is there a memory leak in this C++ program and how to solve it, given the constraints? Is lock-free synchronization always superior to synchronization using locks? Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git Currently focused on React, Next.js, Gatsby. The normal wisdom is to use the the slowest you can stand for the encoding time. Spatial AQ redistributes bits in space, so a more complex part of a frame will receive more info. 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. 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. 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. And embedding it to the project with this html getting the best possible result. Keep in mind Im talking exclusively of x264 level 5.1+. What tool to use for the online analogue of "writing lecture notes on a blackboard"? There is only one time to not use it. https://www.youtube.com/watch?v=bzgFL-gNF9g. Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. hevc_nvenc option information. Should I include the MIT licence of a library which I use from a CDN? explicitly disabled interlaced encoding on Turing, github.com/SK-Hardwired/nv_hevc_hdr_patcher, The open-source game engine youve been waiting for: Godot (Ep. 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. Think of video format as a container that defines file structure for carrying video and audio streams. The honest to god true answer is it depends, however I find that answer unsuitable for my own needs. 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. Thank you very much. (e). If libx265 is too slow use libx264 which is faster but file size will be bigger. Centering layers in OpenLayers v4 after layer loading. x265 uses CRF 18 by default. 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? 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. This is simply for videos using the BT.2020 color primaries. Not bad, but we can do better! Thanks for contributing an answer to Video Production Stack Exchange! For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions. What are some tools or methods I can purchase to trace a water leak? Why using b-frames does not reduce the size of my video (using ffmpeg and nvenc)? They have some good detail on what things mean. Add it next to your -c:v h264_nvenc -c:a ac3 You should also be able to push 2 sessions. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? Let's take a look at what's needed to set up your stream for massively improved quality. I was afraid of lock my server if for some reason too many cameras send files at the same time, and this just simple solve my problem. I will make a few tests with h264. Why are non-Western countries siding with China in the UN? Thanks for contributing an answer to Super User! In the past, I went straight to Handbrakes documentation. When comparing to standard 4.1 profile than yes, x265 outperform it in almost any metric. Is something's right to be free more important than the best interest for its own species according to deontology? What does a search warrant actually look like?
