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. Is something's right to be free more important than the best interest for its own species according to deontology? Keep in mind that fine-tuning any of the options is generally not necessary, unless you absolutely know what you need to change. How did Dominion legally obtain text messages from Fox News hosts? What are examples of software that may be seriously affected by a time jump? Introducing FastFlix AV1 encoder GUI and more! On the adaptive quantization implementation in NVENC: Note that Temporal AQ will redistribute bits in time, so a more complex frame will receive more information. The number of distinct words in a sentence, Torsion-free virtually free-by-cyclic groups. 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. You could probably lower those a little bit if you want, too. Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. 28 and 23 are the default CRF values of x265 and x264 respectively, hence the supposed equivalence. . You can indicate this by, i can link the answer to the other question. 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. Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git However most devices finally have some native h.265 decoding. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? How can the mass of an unstable composite particle become complex? Encode new files to MP4 or MKV. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. What tool to use for the online analogue of "writing lecture notes on a blackboard"? And embedding it to the project with this html getting the best possible result. (d). Thank you very much. For this, you can use -c:v flag. How to increase the number of CPUs in my computer? Create an account to follow your favorite communities and start taking part in conversations. 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 ? 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. Modern video codecs can deliver excellent quality while preserving a very reasonable size. Epic! Now that it is clear, the next important thing to learn is that not every codec is suitable for every video format. The Compilation Guides show you how to do that. 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. How to make PNG video render into 10bit h.264 matroska/avi file? This is a good starting point on why these values matter. Easily beating out the lowest 1% of even CRF 16 medium, two entire steps away. from the chart SSIM difference is very low. In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. . (Well get to that later.). If libx265 is too slow use libx264 which is faster but file size will be bigger. Encode some random segments from typical inputs. Thanks for contributing an answer to Stack Overflow! 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. In ffmpeg documentation that you linked is said that x265 crf 28 is roughly equivalent to x264 crf 23. Quality perception for dynamic pictures differs severely compared to static images, so hacks like this help your video appear of good quality even in case of further reducing the size of a video. WebM is an open, royalty-free media file format designed for the web. Code Calamity 2023. You're still doing high bitrate encoding. FFmpeg supports hardware accelerated decoding and encoding via the hwaccel cuda, h264_cuvid, hevc_cuvid and h264_nvenc, hevc_nvenc modules. (e). 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. Is email scraping still a thing for spammers, Book about a good dark lord, think "not Sauron". So, by clever combination of webm + VP9 and mp4 + H265 for our videos, we can achieve 94% global coverage. The CRF scales for x264 and x265 do not correspond. Use the -g 1 option for FFmpeg 4.3 and newer or if you're using a build from the git master branch. Attempting to do so will result in encoder initialization failure. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? Connect and share knowledge within a single location that is structured and easy to search. (b). By clicking Post Your Answer, you agree to our terms of service, privacy policy and 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. Asking for help, clarification, or responding to other answers. 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. Also, I find it much easier to share single ffmpeg commands across the team instead of showing where to click things in Handbrake. 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. Please read the new article for saving HDR.I have historically been using the older x264 mp4s for my videos, as it just works on everything. 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. If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. The original was H.265 encoded with a .ts extension. Ackermann Function without Recursion or Stack. 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. 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. Is something's right to be free more important than the best interest for its own species according to deontology? Even if your source video doesnt use the HDR color space, it compresses better. (g). Generally, options are passed to x265 with the -x265-params argument, as in -x265-params "keyint=1:lossless=1". At very low bitrates, however, x265 will indeed surpass x264, but at the levels of quality it does with default settings, you will be smudging a lot of fine grain and dark detail and the source would benefit from downscale DNR and pre-processing anyway. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? This uses the native FFmpeg AAC encoder, but under AAC you will find info about more options. YouTubes suggest guidelines for bitrates. The short answer to the deviation from expected performance is that x265 is still under "heavy development". I dont use x265 for anything besides 4k HDR content. 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. rev2023.3.1.43269.

As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). Is email scraping still a thing for spammers. Why are non-Western countries siding with China in the UN? Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). 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. Then I recently read YouTubes suggest guidelines for bitrates. 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. It is faster by two orders of magnitude than libx265, but has some drawbacks. Afterwards compared them to the original using the Structural Similarity Index (SSIM). Okay, okay, lets back up a step and look at the bottom 1% again as well. You get to choose the bitrate. Find centralized, trusted content and collaborate around the technologies you use most. I mainly use Handbrake now use ffmpeg because I learned Handbrake only has a 8-bit internal pipeline. Even though it does cost double the time of medium it really delivers in the quality department. Zero-delay or sliced thread mode has no delay, but this option farther worsens multi-threads quality in supported encoders. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. I used a three minute 4K HDR clip, using Handbrake to only modify which present was used. A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. 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. 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. as in example? What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? But that is all hypothetical. Slower = better video quality and compression. *** ### Encode video as x265 HEVC 10bit. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. My observation is confined to standalone x265 or its deployment, whether in ffmpeg or anything else. 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). The open-source game engine youve been waiting for: Godot (Ep. 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). What is the potential range for a good CRF value? Any idea what might cause this? The real question is HDR. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. Find centralized, trusted content and collaborate around the technologies you use most. It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? Modern web development every year applies new standards for performance. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. I tried to a post a total comment but got a mess. 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. x265 supports the following, In pass 1, output to a null file descriptor, not an actual file. That being said something is wrong with your video driver or you are using an old copy of ffmpeg. The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc. The number of distinct words in a sentence. Add it next to your -c:v h264_nvenc -c:a ac3 You should also be able to push 2 sessions. Making statements based on opinion; back them up with references or personal experience. 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. Call up the binary. 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 Please do not post the same answer to multiple questions. Would the reflected sun's radiation melt ice in LEO? Suspicious referee report, are "suggested citations" from a paper mill? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. But that impacts quality so you will need to test to see what quality is acceptable. 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. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. The normal wisdom is to use the the slowest you can stand for the encoding time. and also why slower and veryslow SSIM is lower than slow preset? Is there a more recent similar source? What's the difference between a power rail and a signal line? But after even a basic compression it cuts down to 1MB. 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. Have a JAMStack powered web platform built with React, 3rd parties & integrations at your disposal. Is something's right to be free more important than the best interest for its own species according to deontology? In this data set, slow is the clear winner in multiple ways. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Should have been already almost completed in all its parts! libvpx-vp9 has the option -deadline which accepts following values: Time to switch to H265 and libx265. Thanks for contributing an answer to Stack Overflow! For everyone else, you can follow instruction on the site. (And if I ran these tests first, I would have even used slow for all the other testing!). 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. Should I include the MIT licence of a library which I use from a CDN? H264 is very popular but much less optimized than VP9 or H265. Can I use a vintage derailleur adapter claw on a modern derailleur. 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. The Compilation Guides show you how to do that. Learn more about Stack Overflow the company, and our products. 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. Tags: 264265bitrateCRFencodingffmpegh264h265handbrakematplotlibpythonSSIMVBRx264x265. 1. How do I avoid objects having flickering edges when I encode a screen recording to mp4 using x264 and ffmpeg? For WebM, it's VP8 and VP9, while in mp4 could be almost anything. I did three CRF videos first, at 22, 20, and 18, then using their resulting bitrates created three ABR videos. So using veryslow is more wise. 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). Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. We haven't used it in VP9 WebM because its architecture does not require this and always guarantees progressive loading. Here is the order in which you have to pass arguments to FFmpeg: (b). But that's probably not what you want. The bitrates are as expected, the higher quality it gets the more bitrate it will need. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? I know from some small scale testing that the gaps between the different presents will remain similar (newer article has better graph for that). But x265 is not yet as mature in its development as x264, so take that CRF equivalence with a pinch of salt. 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. You can list private options available in this encoder with ffmpeg -h encoder=libx265. Call up the appropriate video and audio encoders, and pass necessary arguments to them, such as mappings, bitrates, encoder presets, etc. 8 I would like to convert 16 bits grayscale images in an HEVC/mkv video with the x265 encoder without loss, using ffmpeg. Video and audio streams inside these containers are multimedia data encoded with codec. PTIJ Should we be afraid of Artificial Intelligence? Choose a tune (optional). Antn Garcia. I personally think the extra 2500kbps for the large jump in minimum quality from CRF 24 to CRF 22 is a must. To learn more, see our tips on writing great answers. How can I recognize one? Start by understanding the encoder's options. 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). 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). By default, this is disabled, and it is generally not required to set a tune option. rev2023.3.1.43269. This is why the duplicate flag has been declined. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. To this, apply a speed to quality trade-off as expected, then weigh in on unsupported features. 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. Does ffmpeg really use my Graphics card to encode? Also note that the highest marker on this chart is 0.98, compared the total average charts 0.995. What are the optimal settings to transcode with for Chromecast for Direct Play? Jordan's line about intimate parties in The Great Gatsby? I believe that the last value of 31.6 Mbps is exceeding the capacity of the Chromecast v2. Handbrake 1.2.2. Let's take a look at what's needed to set up your stream for massively improved quality. rev2023.3.1.43269. 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. However, that does not mean smaller file size at the same CRF. 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. Now this is an apples to oranges comparison. What is interesting, is if we put CRF 16 - Medium encodings bitrate on this chart it would go shoot off the top at a staggering 15510kbps! 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. Yes, @Dr.Snail. You can also download a static build, all of which bundle libx265. So I had to ask myself: To find out I would need a lot of comparable data. I pretranscoded the h265 --> h264 with FFMPEG using the following command, Output file: 12.1 Mbps 1080p h264 7.1 AAC mkv. See FFmpeg Wiki: H.264 for more info. explicitly disabled interlaced encoding on Turing, github.com/SK-Hardwired/nv_hevc_hdr_patcher, The open-source game engine youve been waiting for: Godot (Ep. This time with Pre-Analysis. This is best explained with an example. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? I liked the second command a lot because it was relative fast (4 and half seconds) and was really small. 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. ac3 should give you a 15%+ boost in speed. It also wont be constrained to that limit if the video requires a lot more information to capture the complex scene. x265 uses CRF 18 by default. Was Galileo expecting to see so many stars? 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. To know more about this, check out a wonderful demohere. how to use FFMPEG to transcode h264 to h265 on Ubuntu 12.04? Acceleration without force in rotational motion? If you wish to master the tool, you will have to learn how to use flags. Connect and share knowledge within a single location that is structured and easy to search. Therefore I played it safe, bump it down a notch and just encode all of my stuff with x265 10-bit at CRF of 20 on Slow preset. You can remove this scale=858:482: from my scripts. At what point of what we watch as the MCU movies the branching started? (h). 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. PTIJ Should we be afraid of Artificial Intelligence? Best settings for converting from h264 to hevc? 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. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? And since you're on Windows, you may want to remove the shell escapes \ above as I'm writing this from a Unix box testing the command above. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Keep in mind Im talking exclusively of x264 level 5.1+. Then, using that information, proceed to the next step. Note that when using faster presets with the same target bitrate, the resulting quality will be lower and vice-versa. In our case it is 3840px width. Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). The default is 28, and it should visually correspond to libx264 video at CRF 23, but result in about half the file size. hevc_nvenc option information. shouldnt slower preset produce better picture quality? (As a heads up h.265 is the specification, and x265 is encoder for it. However, Im really only dealing with 1080p rips Curious if you have any data on the difference between Medium and Slow settings at 1080p? Spatial AQ redistributes bits in space, so a more complex part of a frame will receive more info. It means there is less differences between the original and the compressed one. Using video for animation with proper optimization is always better than GIF and sometimes outperforms native implementations. Do you think for H.265 but with 1080p and less content that all of what youve posted here would still be applicable or do you think its only for 4k content? Choose the slowest preset that you have patience for. Easiest way to remove 3/16" drive rivets from a lower screen door hinge? Powered by Trac 1.4.2 Could very old employee stock options still be accessible and viable? By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . Open a 2nd command line and encode another .ts at the same time. I don't want others to keep searching for the answer. Strange that the video playback stops if the transcoder gets too far ahead, reaching its buffer limit, on the audio track only? ), In pass 1, you can leave audio out by specifying, P. Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. rev2023.3.1.43269. If you are encoding to x264 or x265, encode to 10-bit if your devices support it. Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. There's a TLDR at the end. 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.
