Does With(NoLock) help with query performance? Let's take a look at what's needed to set up your stream for massively improved quality. Viewing options FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and Even though it does cost double the time of medium it really delivers in the quality department. Visit the Trac open source project athttp://trac.edgewall.org/, Last modified on Oct 5, 2021, 11:32:18 AM. 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. Handbrake 1.2.2. (And if I ran these tests first, I would have even used slow for all the other testing!). So lets take a step back and look at the lowest 1% of the frames. 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. 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. *** CRF 20-23 for most 1080p videos is enough. Theoretically Correct vs Practical Notation. 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. 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). H265, a.k.a HEVC (High-Efficiency Video Coding), is a codec supported by Apple and shows the same 20-50% better efficiency than its H264 older brother. The bitrates are as expected, the higher quality it gets the more bitrate it will need. Also, I raised a flag to mark it as duplicate. I wanted to thank you for all this great work youve done on these articles. Hope that helps, thanks for asking and happy to help! 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. The honest to god true answer is it depends, however I find that answer unsuitable for my own needs. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Find centralized, trusted content and collaborate around the technologies you use most. 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. Use CRF 23+ for videos in 4K. 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). 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. But that's probably not what you want. Making statements based on opinion; back them up with references or personal experience. FFmpeg commands I using are the following: I used 30 as CRF for testing purposes because the artifacts are more visible :). ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless. If libx265 is too slow use libx264 which is faster but file size will be bigger. Why did the Soviets not shoot down US spy satellites during the Cold War? There is no such thing as "proper bitrate". Convert ffmpeg encoding from libx264 to h264_nvenc. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. 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. Jordan's line about intimate parties in The Great Gatsby? 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. The best answers are voted up and rise to the top, Not the answer you're looking for? Nothing to do specifically with libx265 included with ffmpeg See. What are some tools or methods I can purchase to trace a water leak? (e). *** ### Encode video as x265 HEVC 10bit. 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. Their overall average SSIM scores were near as identical. I tried encoding some 4K HDR files using Handbrake and they look washed out. It is well known between pros that SSIM and PSNR are not good measures or SUBJECTIVELY PERCEIVABLE quality. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform.

Thanks for contributing an answer to Stack Overflow! It only takes a minute to sign up. But x265 is not yet as mature in its development as x264, so take that CRF equivalence with a pinch of salt. Would the reflected sun's radiation melt ice in LEO? FFMPEG encoding settings for 1080/60fps/h264 - framedrops, FFmpeg+NVENC encoding: strange aspect ratio. Could very old employee stock options still be accessible and viable? 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. (d). I hope you found this information as useful as I did, if you have any thoughts or feedback please let me know! If you want a single go to setting for encoding, based on my personal testing CRF 20 with Slow preset looks amazing (but may take too long if you are using older hardware). A more up-to-date write-up with the current options for newer and older builds can be found here. You're still doing high bitrate encoding. Is this enough, or should I take some other things into consideration as well? Does With(NoLock) help with query performance? Was Galileo expecting to see so many stars? Could the loss of quality be caused by VLC and its experimental support in deconding h265? how to use FFMPEG to transcode h264 to h265 on Ubuntu 12.04? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. I dont use x265 for anything besides 4k HDR content. from the chart SSIM difference is very low. 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? It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. 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. Even if your source video doesnt use the HDR color space, it compresses better. So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. Press J to jump to the feed. How did Dominion legally obtain text messages from Fox News hosts? I got 700fps (Yours settings) on a GTX750 (non TI) (the cheaper one), I got 925fps (Your settings with ac3 audio), Answered here: 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. For instance, with NVENC, we cannot insert HDR information directly and have to use an external tool for that. FFmpeg supports hardware accelerated decoding and encoding via the hwaccel cuda, h264_cuvid, hevc_cuvid and h264_nvenc, hevc_nvenc modules. Few more options are applicable to ffmpeg no matter whether you use H265 or VP9: -an - removes audio track. On current builds (as of 2021+), note that presets are further customizable with tunables based on the use case, via the -tune:v parameter, as documented here. Additionally to the previously mentioned arguments, ffmpeg VP9 and H265 codecs accept -crf flag . The snippet above assumes that the input file is an MPEG2 stream. When you omit this option, ffmpeg uses -crf 32 for VP9 by . How can I recognize one? Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. I will make a few tests with h264. Another flag you can pass is -movflags faststart. 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. And embedding it to the project with this html getting the best possible result. Thankfully there is a simple answer. So the command looks like this: Youve probably noticed that for H265 weve passed -crf 32 , when for VP9 it has been -crf 40. Applications of super-mathematics to non-super mathematics. Connect and share knowledge within a single location that is structured and easy to search. Thanks @szatmary. So lets take a step back and look at the lowest 1% of the frames. How did StorageTek STC 4305 use backing HDDs? Suspicious referee report, are "suggested citations" from a paper mill? The Compilation Guides show you how to do that. ffmpeg -c:v libx265 -preset fast -crf 28 -tag:v hvc1 -c:a eac3 -b:a 224k -i <source> <target>. So I had to ask myself: To find out I would need a lot of comparable data. 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. All Rights Reserved. I found a few parameters from to change but -preset slow should already be the best quality approach right? Making statements based on opinion; back them up with references or personal experience. (This will generate a logfile that ffmpeg needs for the second pass. Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. 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). Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. 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. Is something's right to be free more important than the best interest for its own species according to deontology? Here is the order in which you have to pass arguments to FFmpeg: (a). 20 medium 66.884759 0.9598, 22 slow 67.187793 0.959167 You are correct: Choose the highest CRF value that provides an acceptable quality. Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Thank you very much. Choose the highest CRF value that provides an acceptable quality. Use CRF 23+ for videos in 4K. There are two most popular tools for video optimization -Handbrake andffmpeg. Do people usually encode with 20+ for 1080p? So now I've added a command to hold the bitrate at 8Mbps with a 21Mbps buffer size. Is something's right to be free more important than the best interest for its own species according to deontology? Acceleration without force in rotational motion? H265 Settings exclusive to H.265/HEVC encoding. For local resources (on an accessible filesystem), the absolute file path is needed. What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? Find centralized, trusted content and collaborate around the technologies you use most. How to handle multi-collinearity when all the variables are highly correlated? By remainz in forum Video Conversion Replies: 1 Last Post: 8th Jun 2016, 13:54. Some popular examples of video formats are mp4, WebM, or MKV. Also note that the highest marker on this chart is 0.98, compared the total average charts 0.995. 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. These gains will be most pronounced at resolutions of 1080p and higher. Every modern browser on desktop and mobile supports it, except Safari on iOS. Something wrong with reddit clipboard. Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. @llogan. For more information, please see our The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. Afterwards compared them to the original using the Structural Similarity Index (SSIM). Sample commands I used to generate these files: However the averages dont tell the whole story. Then, using that information, proceed to the next step. 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 Slower = better video quality and compression. H264 is very popular but much less optimized than VP9 or H265. https://i0.wp.com/codecalamity.com/wp-content/uploads/2019/04/4K_preset_avg_extra.png?ssl=1 why there is CRF 16 and CRF 17 dot showing? As I've previously mentioned, the original file resolution is 5000x2700, but we don't use it that big, and we can try to reduce it to the size that is relevant to the page. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Those other encoders might be better - I haven't studied that PDF closely. My observation is confined to standalone x265 or its deployment, whether in ffmpeg or anything else. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. Think of video format as a container that defines file structure for carrying video and audio streams. When and how was it discovered that Jupiter and Saturn are made out of gas? FFMPEG gop settings. ac3 should give you a 15%+ boost in speed. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Centering layers in OpenLayers v4 after layer loading. Still a vlc bad decoding + libx265 too young? That way I know I should never be disappointed. 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. This should work in your command line. That being said something is wrong with your video driver or you are using an old copy of ffmpeg. Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? 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. 18 medium 67.552191 0.960256, 20 slow 67.835845 0.959723 Anything from 18-40 could give a very decent quality level. 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. 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). I tried to look up the documentation, but i simple don't have the multimedia background to understand it. Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. To know more about this, check out a wonderful demohere. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? Which is very similar to others results as well, so Im personally sticking too it. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? (c). 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). Create an account to follow your favorite communities and start taking part in conversations. 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. 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. shouldnt slower preset produce better picture quality? You can indicate this by, i can link the answer to the other question. 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. Download the SSIM data as CSV. Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. The short answer to the deviation from expected performance is that x265 is still under "heavy development". It looks to take about a crf increase of 2 to achieve near parity of medium to slow (aka 18 medium is close to 20 slow). Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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. I did three CRF videos first, at 22, 20, and 18, then using their resulting bitrates created three ABR videos. If you wanted to target 4 Mbps you'd want to be using veryslow for sure. Centering layers in OpenLayers v4 after layer loading. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Encode new files to MP4 or MKV. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. 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. See a list of available x265 profiles. Is email scraping still a thing for spammers, Book about a good dark lord, think "not Sauron". Keyframes need more data then other frame types to avoid pulsing poor quality keyframes. Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). Is Koestler's The Sleepwalkers still well regarded? 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. It makes your video web-optimized and results in faster video readiness. They have some good detail on what things mean. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. Code Calamity 2023. Modern web development every year applies new standards for performance. https://www.youtube.com/watch?v=bzgFL-gNF9g. I used a three minute 4K HDR clip, using Handbrake to only modify which present was used. is it worth to spend more time to encode slower preset? Should I include the MIT licence of a library which I use from a CDN? Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? I want a setting that I can use on any incoming 4K HDR video I buy. Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). My first step is to convert images into yuv format: ffmpeg -f image2 -i "C:\DATA FOLDER\images%d.png" video.yuv And I try to convert it as a .mkv file, losslessly: However, CRF shows its true edge on the lowest 1%, easily beating out ABR at every turn. Asking for help, clarification, or responding to other answers. The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! Scroll down to the bottom to see notes on the performance impact of presets with this particular encoder. Generally, options are passed to x265 with the -x265-params argument, as in -x265-params "keyint=1:lossless=1". For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. 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. See FFmpeg Wiki: H.265 for more info.

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. You get to choose the bitrate. Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (360p.m3u 8) has not been used for any stream. Does ffmpeg really use my Graphics card to encode? Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? So where does that show up on our chart? As always, start by specifying a preset. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. You can change this by adding -b:v option to ffmpeg. So lets get a little more apples to apples. 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. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. 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.
