If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. Is Koestler's The Sleepwalkers still well regarded? It only takes a minute to sign up. By Edgewall Software The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. Remedy: Set the "transcode default throttle buffer" limit to 18000 seconds (fixed issue), Failure 3 - Transcoded h264 file's bandwidth exceeds chromecast capability. The Compilation Guides show you how to do that. (b). Is email scraping still a thing for spammers. The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! By default, this is disabled, and it is generally not required to set a tune option. What's the difference between a power rail and a signal line? This topic can be confusing, so it's important to learn the difference. 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. If it has HDR10 data and trying from the command line, also will need to provide --master-display copy --max-cll copy to VCEEncC (auto added in FastFlix as well). It only takes a minute to sign up. Thank you!! Centering layers in OpenLayers v4 after layer loading. Handbrake 1.2.2. As with CRF, choose the slowest -preset you can tolerate, and optionally apply a -tune setting. Try running ffprobe on it ( ffprobe -i filename.ts -show_streams ) to see what the format and colorspace are, for HDR should be: pix_fmt=yuv420p10le color_space=bt2020nc color_transfer=smpte2084 color_primaries=bt2020, (Windows ffmpeg/ffprobe package https://ffmpeg.zeranoe.com/builds/, others https://ffmpeg.org/download.html), Found this incredibly helpful, as Ive recently begun ripping Blurays to x265 instead of x264, particularly when I got my new 12-core Ryzen 3900X. This information alone confirmed for me that I will only be using x265 or newer encodings (maybe AV1 in 2020) for storing videos going forward. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. Press question mark to learn the rest of the keyboard shortcuts. As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). Thank you very much. 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. 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. See FFmpeg Wiki: H.265 for more info. If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. 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. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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). What would be the most time effective format and how to convert a raw h.265 video to it? Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? 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). If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? Acceleration without force in rotational motion? Anything from 18-40 could give a very decent quality level. Yes, @Dr.Snail. ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc. Okay, okay, lets back up a step and look at the bottom 1% again as well. We haven't used it in VP9 WebM because its architecture does not require this and always guarantees progressive loading. Also h264 is faster to encode that h265, but again it will impact quality. 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. 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. So lets get a little more apples to apples. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy.

Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. You can remove this scale=858:482: from my scripts. Note: Windows users should use NUL instead of /dev/null and ^ instead of \. rev2023.3.1.43269. 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. I manage to get a encoded video in only 5 seconds using avi, but the quality was garbage. Currently focused on React, Next.js, Gatsby. Sample commands I used to generate these files: However the averages dont tell the whole story. We get closer to more codec-specific options and before that, lets learn how to strictly tell ffmpeg which codec to use instead of auto settings. 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. On the section of video I chose, x264 needed considerably more bitrate to achieve the same score. 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. Call up the binary. I have to use a separate comments for every statement. For this, you can use -c:v flag. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. (c). Choose the slowest preset that you have patience for. Acceleration without force in rotational motion? Would the reflected sun's radiation melt ice in LEO? Use the -x265-params lossless=1 option. So using veryslow is more wise. 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? Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Find centralized, trusted content and collaborate around the technologies you use most. Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. Here is the order in which you have to pass arguments to FFmpeg: (b). I hope you found this information as useful as I did, if you have any thoughts or feedback please let me know! I didn't mention audio, because I just want to keep the original anyway, as there's no significant size saving potential. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? The default is 28, and it should visually correspond to libx264 video at CRF 23, but result in about half the file size. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? 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. Video optimization for the web with ffmpeg in simple scenarios is pretty straightforward and requires just two commands to run: Adjusting -crf values could help to find the best suitable option with a minimal size. Please do not post the same answer to multiple questions. You can also download a static build, all of which bundle libx265. However, that does not mean smaller file size at the same CRF.

Reddit and its partners use cookies and similar technologies to provide you with a better experience. Use CRF 23+ for videos in 4K. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. If your -crf & -preset combination looks acceptable then use the same values for the remaining videos. thank you, I'll try it now and feedback you later ^^, I use it to decrease scale. Because if every frame was that good, we shouldnt need more than 6Mbps x265 or 10Mbps x264 4K video. Please read the new article for saving HDR.I have historically been using the older x264 mp4s for my videos, as it just works on everything. 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. Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? The normal wisdom is to use the the slowest you can stand for the encoding time. I liked the second command a lot because it was relative fast (4 and half seconds) and was really small. Why did the Soviets not shoot down US spy satellites during the Cold War? Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. hevc_videotoolbox is a macOS-specific library that gives native hardware acceleration for H265 encoding. Connect and share knowledge within a single location that is structured and easy to search. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. Use this mode if you want to retain good visual quality and don't care about the exact bitrate or filesize of the encoded file. )Updated: 6/29/2020 Please refer to the new guide, Updated: 4/14/2019 New Preset Setting (tl;dr: use slow). Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ? CEO at Pixel Point and software engineer with 10+ years of web development experience. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022?

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. Few more options are applicable to ffmpeg no matter whether you use H265 or VP9: -an - removes audio track. Replies: 2 Last Post: 20th Jul 2015, 11:17. Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions. 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). In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. So lets take a step back and look at the lowest 1% of the frames. nodejs ffmpeg play video at specific time and stream it to client, ffmpeg mp4 video cannot be played in old tv, Duress at instant speed in response to Counterspell. Scroll down to the bottom to see notes on the performance impact of presets with this particular encoder. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? 18 slow 68.298806 0.96016 And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. 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. Use CRF 23+ for videos in 4K. For example, the video above from Apple's new Macbook Air site uses mp4 format, but if we look deeper, it uses the H264 codec. This uses the native FFmpeg AAC encoder, but under AAC you will find info about more options. Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. I got 700fps (Yours settings) on a GTX750 (non TI) (the cheaper one), I got 925fps (Your settings with ac3 audio), Answered here: I tried to a post a total comment but got a mess. How to increase the number of CPUs in my computer? FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and Here we can see x264 has a much harder time at lower bitrates. Visit the Trac open source project athttp://trac.edgewall.org/, Last modified on Oct 5, 2021, 11:32:18 AM. Why does Jesus turn to the Father to forgive in Luke 23:34? Connect and share knowledge within a single location that is structured and easy to search. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. How to increase the number of CPUs in my computer? and our 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. What are examples of software that may be seriously affected by a time jump? There are two most popular tools for video optimization -Handbrake andffmpeg. You can indicate this by, i can link the answer to the other question. Modern video codecs can deliver excellent quality while preserving a very reasonable size. 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. You get to choose the bitrate. I tried encoding some 4K HDR files using Handbrake and they look washed out. This is needed for functions such as resize,pixel format conversations, de-interlacing, etc. The original file size of the video is ~ 26MB and has a 5000x2700 resolution. CRF affects the quality. Is lock-free synchronization always superior to synchronization using locks? 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. Strange that the video playback stops if the transcoder gets too far ahead, reaching its buffer limit, on the audio track only? Also that I always recommend crf over hard bitrate/filesize because it is really source dependent for saving the proper amount of quality. as in example? Start by understanding the encoder's options. 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, Torsion-free virtually free-by-cyclic groups. By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . Note that hevc_nvenc will almost produce larger files than libx265 at a given quality because it not as efficient as an encoder. 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. Call up the appropriate video and audio encoders, and pass necessary arguments to them, such as mappings, bitrates, encoder presets, etc. See a list of available x265 profiles. Choose a tune (optional). Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Centering layers in OpenLayers v4 after layer loading. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? 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. (This will generate a logfile that ffmpeg needs for the second pass. Suspicious referee report, are "suggested citations" from a paper mill? 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. Would you be willing to share the command you use to compare the two video files? 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. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. Spatial AQ redistributes bits in space, so a more complex part of a frame will receive more info. Think of video format as a container that defines file structure for carrying video and audio streams. Use the -g 1 option for FFmpeg 4.3 and newer or if you're using a build from the git master branch. q Also note that the highest marker on this chart is 0.98, compared the total average charts 0.995. Thanks @szatmary. ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv WOW, I run it with time command, and it converted the video into a mp4 in less than 1 second. 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. 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. PTIJ Should we be afraid of Artificial Intelligence? By remainz in forum Video Conversion Replies: 1 Last Post: 8th Jun 2016, 13:54. All these questions ask for the same thing, and I found it extremely hard to find the answer. The slow preset was used as it was determined to be an ideal choice in previous tests. Also, I find it much easier to share single ffmpeg commands across the team instead of showing where to click things in Handbrake. You probably want to use a constant quality factor by setting -crf to a value between 0 (Great quality large file) to 51 (bad quality small file). It is faster by two orders of magnitude than libx265, but has some drawbacks. To learn more, see our tips on writing great answers. 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. 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. Do not leave these blank. The original was H.265 encoded with a .ts extension. If you wish to master the tool, you will have to learn how to use flags. However, there is still a solution. 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. Through some experimentation I found that I personally never can really see a difference between anything lower than 22 using a Slow present.

Put simply, the closer the result is to 1 the better. I believe that the last value of 31.6 Mbps is exceeding the capacity of the Chromecast v2. 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. In this test, I encoded all videos with ffmpeg using the default presents. *** ### Encode video as x265 HEVC 10bit. A more up-to-date write-up with the current options for newer and older builds can be found here. However, Im really only dealing with 1080p rips Curious if you have any data on the difference between Medium and Slow settings at 1080p? Well, the size was the same (7,7MB, instead of the 3,8MB using the ffmpeg -i without any other option), but it was fast. Let's take a look at what's needed to set up your stream for massively improved quality. - Code Calamity, Animated AVIF is finally coming to Firefox, AMD improves video encoding yet again! The quality difference between llhp and llhq as measured by Netflix's VMAF is virtually negligible, yet the encoder's performance boost (over ~30% on my test bed) with the former is definitely appreciable. (f). By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Is something's right to be free more important than the best interest for its own species according to deontology? How to make PNG video render into 10bit h.264 matroska/avi file? How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? 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. 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. I started with a 4K HDR example video. Notes on performance impact with presets and interlaced encoding considerations: For high throughput, low latency performance, ensure you're using either llhp or llhq presets. Not the answer you're looking for? Even if your source video doesnt use the HDR color space, it compresses better. Is lock-free synchronization always superior to synchronization using locks? compression.ru/video/codec_comparison/hevc_2015/. You can also download a static build, all of which bundle libx265. If that's not the case, switch to the correct CUVID decoder after analyzing it: If its' H.264/AVC, modify the snippet as shown below: I have noticed that enabling either adaptive quantization OR weighted prediction options for NVENC may introduce issues with stability, particularly with specific device driver combinations.

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. Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. FFmpeg best settings to encode Blu-Ray. 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). 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. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Adding -crf 0 is not required. -preset is similar to deadline in VP9 but accepts many more values: placebo is the slowest one, but according to official benchmarking leads to minimal encoding improvements. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? I dont use x265 for anything besides 4k HDR content. What is the potential range for a good CRF value? 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?
