Use CRF 23+ for videos in 4K. And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. ac3 should give you a 15%+ boost in speed. (if you go higher than 4.1 preset). 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Modern web development every year applies new standards for performance. To some, including myself, it could be worth the extra 4000kbps jump from CRF 22 to CRF 20. 1 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. Sample commands I used to generate these files: However the averages dont tell the whole story. All tests run using one of the animations we've made for a recent project. 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. Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. Something wrong with reddit clipboard. The CRF scales for x264 and x265 do not correspond. 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. 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. To learn more, see our tips on writing great answers. (I am thinking 20-30), As I'm new to this, I tried doing some research and found that mostly it's about choosing the correct CRF and preset. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. What would be the most time effective format and how to convert a raw h.265 video to it? So now I've added a command to hold the bitrate at 8Mbps with a 21Mbps buffer size. Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. FFmpeg commands I using are the following: I used 30 as CRF for testing purposes because the artifacts are more visible :). 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). Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. 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). Making statements based on opinion; back them up with references or personal experience. 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. 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. There aren't some commercial products based on x265 nowadays? Through some experimentation I found that I personally never can really see a difference between anything lower than 22 using a Slow present. Suspicious referee report, are "suggested citations" from a paper mill? It is faster by two orders of magnitude than libx265, but has some drawbacks. We haven't used it in VP9 WebM because its architecture does not require this and always guarantees progressive loading. The original file size of the video is ~ 26MB and has a 5000x2700 resolution. 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Additionally to the previously mentioned arguments, ffmpeg VP9 and H265 codecs accept -crf flag . (g). Older versions must use -x265-params keyint=1. The one advantage of hevc_videotoolbox over libx265 is that it supports encoding videos in H265 with alpha channel. 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. 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. 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. This time with Pre-Analysis. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. This topic can be confusing, so it's important to learn the difference. WebM is an open, royalty-free media file format designed for the web. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. Reddit and its partners use cookies and similar technologies to provide you with a better experience. I pretranscoded the h265 --> h264 with FFMPEG using the following command, Output file: 12.1 Mbps 1080p h264 7.1 AAC mkv. 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. CRF works just like in x264, so choose the highest value that provides an acceptable quality. 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. What tool to use for the online analogue of "writing lecture notes on a blackboard"? Thanks for contributing an answer to Super User! ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless. 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. Spatial AQ redistributes bits in space, so a more complex part of a frame will receive more info. Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. and our 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. But that is all hypothetical. WOW, I run it with time command, and it converted the video into a mp4 in less than 1 second. What you want is a min quality level at resulting in a variable bit rate. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? Yes, @Dr.Snail. I want a setting that I can use on any incoming 4K HDR video I buy. It only takes a minute to sign up. Transcoding FLV toMP4 with ffmpeg very slow, FFMPEG resize video not working in browser or IOS. is there a chinese version of ex. 1. @llogan. By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. 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. how to use FFMPEG to transcode h264 to h265 on Ubuntu 12.04? I have a raw footage and the quality of details of h264 with same CRF setting looks better than h265. I use both as .bat files. Epic! This is simply for videos using the BT.2020 color primaries. The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! 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. Keep in mind Im talking exclusively of x264 level 5.1+. What is the potential range for a good CRF value? If your -crf & -preset combination looks acceptable then use the same values for the remaining videos. hevc_videotoolbox is a macOS-specific library that gives native hardware acceleration for H265 encoding. Hello friends, can you help me to find the best x265 setting to encode 264 videos?sorry guys, i still new for ffmpeg. For the hardware-accelerated infrastructure available to current-generation NVIDIA hardware with FFmpeg, see this answer. The Compilation Guides show you how to do that. An addition to the previous comment. Of course, these metrics aren't perfect but you can use them as a rough guide to establish equivalence. However, I head that this cap was removed. Does With(NoLock) help with query performance? Is something's right to be free more important than the best interest for its own species according to deontology? 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. 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. The number of distinct words in a sentence. To learn more, see our tips on writing great answers. In this case, you are using two different encoders, so you get different bitrates. See FFmpeg Wiki: H.265 for more info. For this, you can use -c:v flag. thank you, I'll try it now and feedback you later ^^, I use it to decrease scale. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? 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. 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. 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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). Now that it is clear, the next important thing to learn is that not every codec is suitable for every video format. Does Cosmic Background radiation transmit heat? I got 700fps (Yours settings) on a GTX750 (non TI) (the cheaper one), I got 925fps (Your settings with ac3 audio), Answered here: libvpx-vp9 has the option -deadline which accepts following values: Time to switch to H265 and libx265. Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). 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. You can also download a static build, all of which bundle libx265. Use the -x265-params lossless=1 option.

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. (e). Asking for help, clarification, or responding to other answers. Is this the best possible solution, or is there a better way of doing this? If you wish to master the tool, you will have to learn how to use flags. It's therefore wise to limit thread counts on encodes where latency matters, as the perceived encoder throughput increase offsets any advantages it may bring in the long term. ffmpeg needs to be built with the --enable-gpl --enable-libx265 configuration flags and requires x265 to be installed on your system. I wanted to thank you for all this great work youve done on these articles. Making statements based on opinion; back them up with references or personal experience. It only takes a minute to sign up. So, if generally the CRF of h265 are "better" qualitatively speaking than the x264 ones how is possible that the encode results of x265 is worst than x264 with same CRF ? Declare your inputs. (This will generate a logfile that ffmpeg needs for the second pass. Powered by Trac 1.4.2 To learn more, see our tips on writing great answers. The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. Their overall average SSIM scores were near as identical. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. 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. 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). Higher presets (such as the default medium) have rapidly diminishing returns in quality output while at the same time incurring significant slowdowns in encoder throughput. 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 I believe that the last value of 31.6 Mbps is exceeding the capacity of the Chromecast v2. You get to choose the bitrate. CRF affects the quality. When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. But that's probably not what you want. Connect and share knowledge within a single location that is structured and easy to search. Handbrake 1.2.2. 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. Choose a CRF. You can change this by adding -b:v option to ffmpeg. When you omit this option, ffmpeg uses -crf 32 for VP9 by . as in example? 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. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? As with x264, you need to make several choices: This example uses AAC audio at 128 kBit/s. It can carry video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with theVorbisorOpusaudio codecs. I have only recently discovered FFmpeg and tried using the x265 video codec to reduce the video stream size for some videos, and realized that I can achieve tremendous space savings, especially for video recorded via smarthphones. So lets get a little more apples to apples. Think of video format as a container that defines file structure for carrying video and audio streams. H265 Settings exclusive to H.265/HEVC encoding. Predictable file sizes are a priority. Still a vlc bad decoding + libx265 too young? However, that does not mean smaller file size at the same CRF. Using video for animation with proper optimization is always better than GIF and sometimes outperforms native implementations. (Well get to that later.). You can speed up and slow down encoding ruins presets. Find centralized, trusted content and collaborate around the technologies you use most. Code Calamity 2023. For local resources (on an accessible filesystem), the absolute file path is needed. Put simply, the closer the result is to 1 the better. 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? Download the SSIM data as CSV. Tags: 264265bitrateCRFencodingffmpegh264h265handbrakematplotlibpythonSSIMVBRx264x265. There is only one time to not use it. 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). CRF is the best of both worlds. ffmpeg -i input.h265 -c copy -movflags +faststart output.mp4 The camera's H.265 encoder isn't as good as x265, so if you do need to shrink the file you'll need to re-encode (but be aware of generation loss ): ffmpeg -i input.h265 -c:v libx265 -crf 28 -preset medium -movflags +faststart output.mp4 Adjust -crf and -preset to your liking. You can indicate this by, i can link the answer to the other question. (c). They claim that a 4K video coming into their site should optimally be 35~45Mbps when encoded with the older x264 codecs. Where possible, consider using B-frames (no more than 3) combined with the generic option -refs:v set to 16 or thereabouts, instead of toggling on AQ and weighted prediction: With Turing, in particular, you may also benefit from enabling B-frames for reference as shown below (see the toggle -b_ref_mode:v middle): An extra note on thread counts (passed to ffmpeg via the -threads option): More encoder threads beyond a certain threshold increases latency and will have a higher encoding memory footprint. Replies: 2 Last Post: 20th Jul 2015, 11:17. Could very old employee stock options still be accessible and viable? For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. Server: MacBook Pro with 2.66GHz i7, 4GB DDR3Connection to router: 5GHz WiFiMonitored with Tautulli (PlexPy), Chromecast v2 --> Onkyo Receiver 7.1 setup --> 1080p Sony Projector, Chromecast v1 --> Yamaha Receiver 5.1 setup --> 1080p TV, Amazon Firestick --> Yamaha Receiver 5.1 setup --> 1080p TV, These are connected over 2.4 GHz, unfortunately, (I know, I'm running some seriously old components in heresome are a decade old. 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. I started with a 4K HDR example video. This is best explained with an example. 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 However, Im really only dealing with 1080p rips Curious if you have any data on the difference between Medium and Slow settings at 1080p? rev2023.3.1.43269. At what point of what we watch as the MCU movies the branching started? Unfortunately, the same can't be said about videos. You're still doing high bitrate encoding. PTIJ Should we be afraid of Artificial Intelligence? ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc. Let's take a look at what's needed to set up your stream for massively improved quality. Just curious. 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. 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. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. 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. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. 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. Is email scraping still a thing for spammers. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. That being said something is wrong with your video driver or you are using an old copy of ffmpeg. It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. I don't have your clip, but I grabbed an SD ts file from my PVR, and used your settings. I tried encoding some 4K HDR files using Handbrake and they look washed out. Afterwards compared them to the original using the Structural Similarity Index (SSIM). Was Galileo expecting to see so many stars? But after even a basic compression it cuts down to 1MB. This is why the duplicate flag has been declined. The slow preset was used as it was determined to be an ideal choice in previous tests. Okay, okay, lets back up a step and look at the bottom 1% again as well. Theoretically Correct vs Practical Notation. Another flag you can pass is -movflags faststart. Still, we get a good idea of where these show up. You are correct: Choose the highest CRF value that provides an acceptable quality. In this data set, slow is the clear winner in multiple ways. It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? 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. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. Please do not post the same answer to multiple questions. I dont use x265 for anything besides 4k HDR content. I know from some small scale testing that the gaps between the different presents will remain similar (newer article has better graph for that). Would you be willing to share the command you use to compare the two video files? Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee. The Compilation Guides show you how to do that. (And if I ran these tests first, I would have even used slow for all the other testing!). (d). 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. So what *is* the Latin word for chocolate? Great explanation. 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. Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. I tried to look up the documentation, but i simple don't have the multimedia background to understand it. Modern video codecs can deliver excellent quality while preserving a very reasonable size. Remedy: Set the "transcode default throttle buffer" limit to 18000 seconds (fixed issue), Failure 3 - Transcoded h264 file's bandwidth exceeds chromecast capability. If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ? See a list of available x265 profiles. Even if your source video doesnt use the HDR color space, it compresses better. x265 CRF 28 is supposed to be equivalent to x264 CRF 23. Start by understanding the encoder's options. 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. How did Dominion legally obtain text messages from Fox News hosts? And embedding it to the project with this html getting the best possible result. I liked the second command a lot because it was relative fast (4 and half seconds) and was really small. Also, I raised a flag to mark it as duplicate. ), In pass 1, you can leave audio out by specifying, P. Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. It is not a royalty-free codec - perhaps, that is why the adoption rate is much less than of WebM's. Open a 2nd command line and encode another .ts at the same time. 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. When you omit this option, ffmpeg uses -crf 32 for VP9 by default. It states that for 4K videos with x265 they suggest a Constant Rate Factor (CRF) encoding in the range of 22-28 (the larger the number the lower the quality). Thank you!! They have some good detail on what things mean. 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. 18 medium 67.552191 0.960256, 20 slow 67.835845 0.959723 (As a heads up h.265 is the specification, and x265 is encoder for it. However most devices finally have some native h.265 decoding. Here is the order in which you have to pass arguments to FFmpeg: (a). Jordan's line about intimate parties in The Great Gatsby? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Should I include the MIT licence of a library which I use from a CDN? So lets take a step back and look at the lowest 1% of the frames. 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. All Rights Reserved.
