When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? We have some hard date, lets use it. Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. Pythons New Structural Pattern Matching! Not sure if theyre agnostic of resolution. Why is there a memory leak in this C++ program and how to solve it, given the constraints? My experience with using nvenc is that you need to tell it what bitrate you want -- it defaults to VBR, which is fine, but no amount of tuning makes up for the fact that it always wants to give you a 2M average bitrate no matter what resolution file you feed it. Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? 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. @Dr.Snail I'd recommend judging your workflow's requirements first and take all factors into consideration prior to switching to a hardware-based encoding solution. If you require interlaced encoding support, please switch to Pascal or older SKUs instead. ffmpeg -framerate 30 -i in.265 -i in.avi -c copy -map 0:v -map 1:a -video_track_timescale 1k fixed.mp4 Replace the framerate value with the true rate of the video. I guess this solves my problem. If the same information really answers both questions, then one question (usually the newer one) should be closed as a duplicate of the other. FFmpeg supports hardware accelerated decoding and encoding via the hwaccel cuda, h264_cuvid, hevc_cuvid and h264_nvenc, hevc_nvenc modules. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. In this case, you are using two different encoders, so you get different bitrates. The Compilation Guides show you how to do that. Modern web development every year applies new standards for performance. This uses the native FFmpeg AAC encoder, but under AAC you will find info about more options. I will make a few tests with h264. You can list private options available in this encoder with ffmpeg -h encoder=libx265. For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. I tried to look up the documentation, but i simple don't have the multimedia background to understand it. For WebM, it's VP8 and VP9, while in mp4 could be almost anything. Making statements based on opinion; back them up with references or personal experience. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? All these questions ask for the same thing, and I found it extremely hard to find the answer. Nothing to do specifically with libx265 included with ffmpeg See. ac3 should give you a 15%+ boost in speed. By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . For this, you can use -c:v flag. Visit the Trac open source project athttp://trac.edgewall.org/, Last modified on Oct 5, 2021, 11:32:18 AM. Yes, @Dr.Snail. Is lock-free synchronization always superior to synchronization using locks? 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. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. 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. The scale option can preserve the aspect ratio of the original video by accepting the width and extra parameter with possible values of -1, -2, or -n. -2 value guarantees that the resulted output resolution will be even. Super User is a question and answer site for computer enthusiasts and power users. Handbrake has a GUI, and it makes it much easier to use; however, using ffmpeg is a more flexible option in case you want to render videos with alpha(transparent) channels or use hardware acceleration that speeds up compression a lot. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Thanks @szatmary. Does With(NoLock) help with query performance? Thanks for contributing an answer to Video Production Stack Exchange! 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. libvpx-vp9 has the option -deadline which accepts following values: Time to switch to H265 and libx265. ffmpeg -c:v libx265 -preset fast -crf 28 -tag:v hvc1 -c:a eac3 -b:a 224k -i <source> <target>. Still, we get a good idea of where these show up. Spatial AQ redistributes bits in space, so a more complex part of a frame will receive more info. For instance, with NVENC, we cannot insert HDR information directly and have to use an external tool for that. Asking for help, clarification, or responding to other answers. I started with a 4K HDR example video. Connect and share knowledge within a single location that is structured and easy to search. Well well wishing well, that is even more definitive. For some videos, you can try using the low resolution option, but on retina screens, it could lead to a blurry picture. 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? Start by understanding the encoder's options. 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. Does Cosmic Background radiation transmit heat? 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. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Create an account to follow your favorite communities and start taking part in conversations. (This will generate a logfile that ffmpeg needs for the second pass. Thank you very much. q This time with Pre-Analysis. So using veryslow is more wise. ffmpeg is a CLI tool and it has a lot of options that is nice to know. 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. But after even a basic compression it cuts down to 1MB. It is well known between pros that SSIM and PSNR are not good measures or SUBJECTIVELY PERCEIVABLE quality. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. (And if I ran these tests first, I would have even used slow for all the other testing!). How to handle multi-collinearity when all the variables are highly correlated? 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. Why are non-Western countries siding with China in the UN? See a list of available x265 profiles. rev2023.3.1.43269. Strange that the video playback stops if the transcoder gets too far ahead, reaching its buffer limit, on the audio track only? Has Microsoft lowered its Windows 11 eligibility criteria? 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. Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). ffmpeg needs to be built with the --enable-gpl --enable-libx265 configuration flags and requires x265 to be installed on your system. Thanks for contributing an answer to Super User! I dont use x265 for anything besides 4k HDR content. I personally think the extra 2500kbps for the large jump in minimum quality from CRF 24 to CRF 22 is a must. Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (360p.m3u 8) has not been used for any stream. When it comes to bitrates, ensure that your desired values are set via the -b:v, -maxrate:v and -bufsize:v options. For everyone else, you can follow instruction on the site. 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 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. Video and audio streams inside these containers are multimedia data encoded with codec. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. A few interesting options for us are: libvpx-vp9 - which is used be default when you convert to WebM using VP9 codec, libx265 - for H265 code and mp4 container, hevc_videotoolbox - for H265 with a hardware acceleration. It only takes a minute to sign up. Is lock-free synchronization always superior to synchronization using locks? This is why the duplicate flag has been declined. 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. Even though it does cost double the time of medium it really delivers in the quality department. You get to choose the bitrate. Modern video codecs can deliver excellent quality while preserving a very reasonable size. (if you go higher than 4.1 preset). PTIJ Should we be afraid of Artificial Intelligence? How can I use CRF encoding with nvenc in ffmpeg? 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. I want a setting that I can use on any incoming 4K HDR video I buy. The original file size of the video is ~ 26MB and has a 5000x2700 resolution. The only point of using x265 is for compatibility, lossless and HDR content, otherwise, even at SDR 4k x264 will fare better if given enough bitrate. if you don't, the encoder will choose on for you. 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. To learn more, see our tips on writing great answers. 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. I use both as .bat files. -vf - the option for passing filters to ffmpeg. From my FFmpeg cheatsheet: *** CRF 20-23 for most 1080p videos is enough. Is email scraping still a thing for spammers. 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. Use CRF 23+ for videos in 4K. 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. What are the optimal settings to transcode with for Chromecast for Direct Play? By default, this is disabled, and it is generally not required to set a tune option. Please do not post the same answer to multiple questions. Asking for help, clarification, or responding to other answers. 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. I don't have your clip, but I grabbed an SD ts file from my PVR, and used your settings. 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). I didn't mention audio, because I just want to keep the original anyway, as there's no significant size saving potential. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. Even if your source video doesnt use the HDR color space, it compresses better. 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. How to make PNG video render into 10bit h.264 matroska/avi file? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. There aren't some commercial products based on x265 nowadays? You can change this by adding -b:v option to ffmpeg. 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. 28 and 23 are the default CRF values of x265 and x264 respectively, hence the supposed equivalence. CRF affects the quality. The best answers are voted up and rise to the top, Not the answer you're looking for? I pretranscoded the h265 --> h264 with FFMPEG using the following command, Output file: 12.1 Mbps 1080p h264 7.1 AAC mkv. In the past, I went straight to Handbrakes documentation. Choose the slowest preset that you have patience for. Should have been already almost completed in all its parts! Thank you!! Best settings for converting from h264 to hevc? Should the results be the same, relatively? 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. I have a raw footage and the quality of details of h264 with same CRF setting looks better than h265. Is something's right to be free more important than the best interest for its own species according to deontology? ), In pass 1, you can leave audio out by specifying, P. Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. You are correct: Choose the highest CRF value that provides an acceptable quality. 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. Put simply, the closer the result is to 1 the better. 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. An addition to the previous comment. And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. Getting ffmpeg with libx265 support ffmpeg needs to be built with the --enable-gpl --enable-libx265 configuration flags and requires x265 to be installed on your system. Introducing FastFlix AV1 encoder GUI and more! Should I include the MIT licence of a library which I use from a CDN? Great explanation. is it worth to spend more time to encode slower preset? is there a chinese version of ex. and our Because if every frame was that good, we shouldnt need more than 6Mbps x265 or 10Mbps x264 4K video. Could very old employee stock options still be accessible and viable? Now that it is clear, the next important thing to learn is that not every codec is suitable for every video format. and also why slower and veryslow SSIM is lower than slow preset? As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). Would the reflected sun's radiation melt ice in LEO? This will be very fast as it is "copying and pasting" the H.265 video into the MP4 container: 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): Adjust -crf and -preset to your liking. (b). You need to download the model you want to use (vmaf_4k_v0.6.1.pkl and vmaf_4k_v0.6.1.pkl.model in my case) from https://github.com/Netflix/vmaf/tree/master/model. 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. YouTubes suggest guidelines for bitrates. But that is all hypothetical. (As a heads up h.265 is the specification, and x265 is encoder for it. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. Famous codecs are H264, H265, and VP8/9. Encode new files to MP4 or MKV. Powered by Trac 1.4.2 To this, apply a speed to quality trade-off as expected, then weigh in on unsupported features. Which is very similar to others results as well, so Im personally sticking too it. rev2023.3.1.43269. Making statements based on opinion; back them up with references or personal experience. Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. as in example? Press J to jump to the feed. Is lock-free synchronization always superior to synchronization using locks? Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. Replies: 2 Last Post: 20th Jul 2015, 11:17. PTIJ Should we be afraid of Artificial Intelligence? Use the -x265-params lossless=1 option. Applications of super-mathematics to non-super mathematics. So, I'll link to the other answer that I posted. Thankfully there is a simple answer. 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. Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). Thanks for contributing an answer to Stack Overflow! Some popular examples of video formats are mp4, WebM, or MKV. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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). 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 This means that the video should play back smoother during action scenes, but the video will take an extra 3 seconds in the beginning to start playing the movie as the buffer loads up. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. See HWAccelIntro for information on supported hardware H.265/HEVC encoders. Not the answer you're looking for? How can I recognize one? Hmm interesting, may i ask why this scales doesn't correspond? 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. 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. 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. 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.
