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. 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. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. 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. Also, I find it much easier to share single ffmpeg commands across the team instead of showing where to click things in Handbrake. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. 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. 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. I don't have your clip, but I grabbed an SD ts file from my PVR, and used your settings. CRF affects the quality. 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. How to increase the number of CPUs in my computer? RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. You can speed up and slow down encoding ruins presets. Then in three years H.266 / VVC toolsets will probably be popping up. 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. So what *is* the Latin word for chocolate? How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? (d). To learn more, see our tips on writing great answers. See FFmpeg Wiki: H.264 for more info. For some videos, you can try using the low resolution option, but on retina screens, it could lead to a blurry picture. The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Introducing FastFlix AV1 encoder GUI and more! 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. Is there a more recent similar source? shouldnt slower preset produce better picture quality? 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. 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 can change this by adding -b:v option to ffmpeg. The original was H.265 encoded with a .ts extension. Put simply, the closer the result is to 1 the better. Is email scraping still a thing for spammers. Modern video codecs can deliver excellent quality while preserving a very reasonable size. 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. Then, using that information, proceed to the next step. You can also download a static build, all of which bundle libx265. How to increase the number of CPUs in my computer? See HWAccelIntro for information on supported hardware H.265/HEVC encoders. And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. The SSIM result is done frame by frame, so we have to average them all together to see which is best overall. Jordan's line about intimate parties in The Great Gatsby? In this test, I encoded all videos with ffmpeg using the default presents. Modern web development every year applies new standards for performance. Think of video format as a container that defines file structure for carrying video and audio streams. What are the best settings for me to use when encoding x265 videos? Depends on the encoder, the ffmpeg one I dont think supports 10 bit, but VCEEncC does. hevc_nvenc option information. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. Adapt as necessary to your encoding requirements. And bitrate directly correlates to file size. Thankfully there is a simple answer. 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. The Main profile is capable of 8-bit, Main 10-bit is capable of 10-bit, and Range Extended is capable of more than 10-bit. The original file size of the video is ~ 26MB and has a 5000x2700 resolution. Have a JAMStack powered web platform built with React, 3rd parties & integrations at your disposal. Asking for help, clarification, or responding to other answers. 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. Is this enough, or should I take some other things into consideration as well? 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. Predictable file sizes are a priority. 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. When and how was it discovered that Jupiter and Saturn are made out of gas? 31 is recommended for 1080p HD video: ffmpeg -i input.mp4 -c:v libvpx-vp9 -crf 31 -b:v 0 output.mkv Connect and share knowledge within a single location that is structured and easy to search. Some popular examples of video formats are mp4, WebM, or MKV. It only takes a minute to sign up. rev2023.3.1.43269. Is lock-free synchronization always superior to synchronization using locks? Best settings for converting from h264 to hevc? The default is 28, and it should visually correspond to libx264 video at CRF 23, but result in about half the file size. Theoretically Correct vs Practical Notation. 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 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. However, Im really only dealing with 1080p rips Curious if you have any data on the difference between Medium and Slow settings at 1080p? Anything from 18-40 could give a very decent quality level. A home for professional coders articles, opinions and ideas. I tried to look up the documentation, but i simple don't have the multimedia background to understand it. Has Microsoft lowered its Windows 11 eligibility criteria? Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions. Libvorbis for audio seems slow. 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). To learn more, see our tips on writing great answers. What is the potential range for a good CRF value? Great explanation. Your inputs are already H.265/HEVC, so you can simply mux them into MP4 without needing to re-encode. 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. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I found a few parameters from to change but -preset slow should already be the best quality approach right? I mainly use Handbrake now use ffmpeg because I learned Handbrake only has a 8-bit internal pipeline. If you wish to master the tool, you will have to learn how to use flags. It can carry video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with theVorbisorOpusaudio codecs. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. 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. Privacy Policy. Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). Thanks @szatmary. Suspicious referee report, are "suggested citations" from a paper mill? Reddit and its partners use cookies and similar technologies to provide you with a better experience. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? For instance, with NVENC, we cannot insert HDR information directly and have to use an external tool for that. and also why slower and veryslow SSIM is lower than slow preset? . By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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. Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (360p.m3u 8) has not been used for any stream. 3 seconds at the start is nothing as long as the movie plays fine. You will have to tweak A LOT of the extra complex settings of x265 encoder to even MATCH x264, let alone surpass it in size to perceivable quality, and by the time you do, you will see that x265 is just a order of magnitude slower than x264 to achieve marginally better results which is very problematic with 4k encodes. But that impacts quality so you will need to test to see what quality is acceptable. (c). However, that does not mean smaller file size at the same CRF. Although I've been using Plex for years, my setup is far inferior to most of the people on this forum. Could the loss of quality be caused by VLC and its experimental support in deconding h265? 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. See a list of available x265 profiles. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Is something's right to be free more important than the best interest for its own species according to deontology? Making statements based on opinion; back them up with references or personal experience. Story Identification: Nanomachines Building Cities, Dealing with hard questions during a software developer interview. I started with a 4K HDR example video. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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. Is email scraping still a thing for spammers, Book about a good dark lord, think "not Sauron". 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. x265 uses CRF 18 by default. FFmpeg best settings to encode Blu-Ray. Do not leave these blank. Epic! Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? Thanks for contributing an answer to Stack Overflow! H264 is very popular but much less optimized than VP9 or H265. 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. You're still doing high bitrate encoding. Sorry for the long post. Open a 2nd command line and encode another .ts at the same time. 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). 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. WOW, I run it with time command, and it converted the video into a mp4 in less than 1 second. Does With(NoLock) help with query performance? 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. Do people usually encode with 20+ for 1080p? 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. Then I recently read YouTubes suggest guidelines for bitrates. (if you go higher than 4.1 preset). The Compilation Guides show you how to do that. By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . Also note that the highest marker on this chart is 0.98, compared the total average charts 0.995. x265 CRF 28 is supposed to be equivalent to x264 CRF 23. 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. rev2023.3.1.43269. So lets get a little more apples to apples. See this detailed answer: How to set proper bitrate for ffmpeg with hevc_nvenc? I guess this solves my problem. 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. Making statements based on opinion; back them up with references or personal experience. Currently focused on React, Next.js, Gatsby. I use both as .bat files. Centering layers in OpenLayers v4 after layer loading. What's the difference between a power rail and a signal line? There are two most popular tools for video optimization -Handbrake andffmpeg. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? 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. Press question mark to learn the rest of the keyboard shortcuts. Declare your inputs. I don't want others to keep searching for the answer. I may mix it up myself in this article, dont worry about the letter, just the numbers. 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. @llogan. First thing I did was to chop out a minute segment and promptly remove the HDR. To learn more, see our tips on writing great answers. Choose a CRF. It means there is less differences between the original and the compressed one. So where does that show up on our chart? Definitely not for archiving. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. ac3 should give you a 15%+ boost in speed. 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. For this, you can use -c:v flag. Here is the order in which you have to pass arguments to FFmpeg: (b). There is no such thing as "proper bitrate". If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. Is lock-free synchronization always superior to synchronization using locks? I have to use a separate comments for every statement. They have some good detail on what things mean. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. hevc_videotoolbox is a macOS-specific library that gives native hardware acceleration for H265 encoding. 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. 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. 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). Let's take a look at what's needed to set up your stream for massively improved quality. Still a vlc bad decoding + libx265 too young? 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 manage to get a encoded video in only 5 seconds using avi, but the quality was garbage. Even if your source video doesnt use the HDR color space, it compresses better. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? Learn more about Stack Overflow the company, and our products. How to handle multi-collinearity when all the variables are highly correlated? 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. FFMPEG gop settings. The absolute path to the output file. Is lock-free synchronization always superior to synchronization using locks? It is faster by two orders of magnitude than libx265, but has some drawbacks. Encode some random segments from typical inputs. You can remove this scale=858:482: from my scripts. Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? FFmpeg: For NVENC, what is a concurrent surface? This should work in your command line. 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. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Still, we get a good idea of where these show up. But x265 is not yet as mature in its development as x264, so take that CRF equivalence with a pinch of salt. Call up the appropriate video and audio encoders, and pass necessary arguments to them, such as mappings, bitrates, encoder presets, etc. Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? Should the results be the same, relatively? Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. How do I avoid objects having flickering edges when I encode a screen recording to mp4 using x264 and ffmpeg? When the device you are going to watch it on doesnt support it. Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). How can I recognize one? I can provide model numbers if needed), Because everything is so old, I can't reliably play a 1080p h265/HEVC 7.1 movie at full quality without some stuttering. 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. compression.ru/video/codec_comparison/hevc_2015/. Even though it does cost double the time of medium it really delivers in the quality department. To make your file compatible with Apple "industry standard" H.265 you have to add the following argument -tag:v hvc1. 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. It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. *** ### Encode video as x265 HEVC 10bit. 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. Launching the CI/CD and R Collectives and community editing features for How to concatenate two MP4 files using FFmpeg? Suspicious referee report, are "suggested citations" from a paper mill?
