Keep in mind that is while still being lesser quality than CRF 18 - Slow. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. By MvL in forum Video Conversion Replies: 3 Last Post: 8th Jul 2014, 17:55 . Use the -g 1 option for FFmpeg 4.3 and newer or if you're using a build from the git master branch. Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. (As a heads up h.265 is the specification, and x265 is encoder for it. 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. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Ive specified it to 3x the 8Mbps (so 21M). My observation is confined to standalone x265 or its deployment, whether in ffmpeg or anything else. It is faster by two orders of magnitude than libx265, but has some drawbacks. The open-source game engine youve been waiting for: Godot (Ep. 20 medium 66.884759 0.9598, 22 slow 67.187793 0.959167 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 ? @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. Does ffmpeg really use my Graphics card to encode? 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 (c). FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and 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. Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. That way I know I should never be disappointed. When you omit this option, ffmpeg uses -crf 32 for VP9 by . My first step is to convert images into yuv format: ffmpeg -f image2 -i "C:\DATA FOLDER\images%d.png" video.yuv And I try to convert it as a .mkv file, losslessly: 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. Some popular examples of video formats are mp4, WebM, or MKV. https://www.youtube.com/watch?v=bzgFL-gNF9g. Powered by Trac 1.4.2 Use CRF 23+ for videos in 4K. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? rev2023.3.1.43269. How can the mass of an unstable composite particle become complex? Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (360p.m3u 8) has not been used for any stream. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. I see, so because of this heavy development status even if I decide to move from ffmpeg and libx265 to another encoder the results will not change so much right? Their overall average SSIM scores were near as identical. Definitely not for archiving. Download the SSIM data as CSV. In this case, you are using two different encoders, so you get different bitrates. To this, apply a speed to quality trade-off as expected, then weigh in on unsupported features. . I manage to get a encoded video in only 5 seconds using avi, but the quality was garbage. 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. 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. (f). Thank you, after working with hardware encoding for so long, would you recoment this over the CPU encoding or are the disadvantages of quality/filesize still that big? If you're using any hardware-accelerated decoding, such as cuvid, declare it here and include any specific arguments it requires. What's the difference between a power rail and a signal line? For more information, please see our In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. I may mix it up myself in this article, dont worry about the letter, just the numbers. 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. Introducing FastFlix AV1 encoder GUI and more! What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? Currently focused on React, Next.js, Gatsby. I use the monochrome12 profile. compression.ru/video/codec_comparison/hevc_2015/. - Code Calamity, Animated AVIF is finally coming to Firefox, AMD improves video encoding yet again! Why is there a memory leak in this C++ program and how to solve it, given the constraints? It is less efficient in terms of optimization and does not have Constant Quality mode (-crf) and presets we used in the previous example. For fine-tuning the encoding process, you can therefore pass any option that is listed in the x265 documentation. Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? How to increase the number of CPUs in my computer? Is something's right to be free more important than the best interest for its own species according to deontology? Open a 2nd command line and encode another .ts at the same time. 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. The best answers are voted up and rise to the top, Not the answer you're looking for? 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? Find centralized, trusted content and collaborate around the technologies you use most. Also that I always recommend crf over hard bitrate/filesize because it is really source dependent for saving the proper amount of quality. And bitrate directly correlates to file size. 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. Older versions must use -x265-params keyint=1. Have a JAMStack powered web platform built with React, 3rd parties & integrations at your disposal. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? 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. rev2023.3.1.43269. PTIJ Should we be afraid of Artificial Intelligence? Slower = better video quality and compression. 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. 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. 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. WebM is an open, royalty-free media file format designed for the web. ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless. Hmm interesting, may i ask why this scales doesn't correspond? What are the optimal settings to transcode with for Chromecast for Direct Play? Choose a CRF. Thanks for contributing an answer to Video Production Stack Exchange! Learn more about Stack Overflow the company, and our products. As with CRF, choose the slowest -preset you can tolerate, and optionally apply a -tune setting. At what point of what we watch as the MCU movies the branching started? To learn more, see our tips on writing great answers. You can list private options available in this encoder with ffmpeg -h encoder=libx265. If youre a macOS user, use brew to install it. *** CRF 20-23 for most 1080p videos is enough. It only takes a minute to sign up.

Scroll down to the bottom to see notes on the performance impact of presets with this particular encoder. Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git Choose the slowest preset that you have patience for. You can also download a static build, all of which bundle libx265. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. There is only one time to not use it. As always, start by specifying a preset. 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. 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. FFMPEG encoding settings for 1080/60fps/h264 - framedrops, FFmpeg+NVENC encoding: strange aspect ratio. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Please do not post the same answer to multiple questions. See FFmpeg Wiki: H.265 for more info. Any idea what might cause this? Not the answer you're looking for? Even if there is no sound in a file, there could be empty audio track information that will occupy some additional weight, so always use it for muted videos. (if you go higher than 4.1 preset). How to increase the number of CPUs in my computer? I tried to a post a total comment but got a mess. Connect and share knowledge within a single location that is structured and easy to search. Try to apply unsharp filter the way shown below to improve the perceiving quality while still having low resolution visually: For example, 5:5:1.0 will result in medium sharpness; for the light one, try to use 3:3:1.0, and for the strong one, pass down 9:9:1.0. Here is the order in which you have to pass arguments to FFmpeg: (a). Create an account to follow your favorite communities and start taking part in conversations. Well well wishing well, that is even more definitive. Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. At both CRF 24 and CRF 22, even the lowest frames dont dip below SSIM 0.95. @llogan.

Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? 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. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? The difference between the input and the output is practically non-visible for 1080p videos. Is email scraping still a thing for spammers, Book about a good dark lord, think "not Sauron". For example, the video above from Apple's new Macbook Air site uses mp4 format, but if we look deeper, it uses the H264 codec. When you omit this option, ffmpeg uses -crf 32 for VP9 by default. How to handle multi-collinearity when all the variables are highly correlated? But i don't think that I am doing it in the most effective way. ), In pass 1, you can leave audio out by specifying, P. Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. Encode new files to MP4 or MKV. 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. Frameworks compete by optimizing network requests, images, and code to achieve a blazing-fast loading experience. 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. Would the reflected sun's radiation melt ice in LEO? 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. Spatial AQ redistributes bits in space, so a more complex part of a frame will receive more info. Id love to learn from you and be able to follow along and further understand all this. Press question mark to learn the rest of the keyboard shortcuts. How do I avoid objects having flickering edges when I encode a screen recording to mp4 using x264 and ffmpeg? Something wrong with reddit clipboard. Handbrake 1.2.2. I have read that previously, Chromecast used to limit playback at 11 Mbps. 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. 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. 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. I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). rev2023.3.1.43269. In the same breath, note that NVIDIA has explicitly disabled interlaced encoding on Turing across all tiers, even the 1650 uses the older Volta NVENC encoder. 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. If you wish to master the tool, you will have to learn how to use flags. While its narrow versatility makes it incredibly frustrating to work with, there's never been another video player in history that scrubs as well, or uses laptop CPU/battery as efficiently. Asking for help, clarification, or responding to other answers. As a bonus you can use the following nice shell script below that can create for you optimized video in VP9 and H265 with a single command. Predictable file sizes are a priority.

However, CRF shows its true edge on the lowest 1%, easily beating out ABR at every turn. 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. Or for GPU-based encoding, which is much faster, but . 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. Suspicious referee report, are "suggested citations" from a paper mill? ffmpeg -c:v libx265 -preset fast -crf 28 -tag:v hvc1 -c:a eac3 -b:a 224k -i <source> <target>. Learn more about Stack Overflow the company, and our products. For everyone else, you can follow instruction on the site. 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. Why are non-Western countries siding with China in the UN? 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. Could very old employee stock options still be accessible and viable? The short answer to the deviation from expected performance is that x265 is still under "heavy development". Use this mode if you want to retain good visual quality and don't care about the exact bitrate or filesize of the encoded file. Here is the order in which you have to pass arguments to FFmpeg: (b). Afterwards compared them to the original using the Structural Similarity Index (SSIM). And one last thing is -tag:v hvc1 that makes video work on iOS and macOS devices. 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.

I mainly use Handbrake now use ffmpeg because I learned Handbrake only has a 8-bit internal pipeline. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). CRF affects the quality. Theoretically Correct vs Practical Notation. If you look at the PDF I linked in the last comment, there are many encoders out there - most proprietary. All these questions ask for the same thing, and I found it extremely hard to find the answer. Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions. x265 CRF 28 is supposed to be equivalent to x264 CRF 23. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Making statements based on opinion; back them up with references or personal experience. 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. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. The Compilation Guides show you how to do that. Attempting to do so will result in encoder initialization failure. 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). PTIJ Should we be afraid of Artificial Intelligence? Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Libvorbis for audio seems slow. You can remove this scale=858:482: from my scripts. 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. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. Famous codecs are H264, H265, and VP8/9. You can also download a static build, all of which bundle libx265. This is why the duplicate flag has been declined. 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. Not the answer you're looking for? Thanks for contributing an answer to Super User! Encode some random segments from typical inputs. 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. Why did the Soviets not shoot down US spy satellites during the Cold War? Then in three years H.266 / VVC toolsets will probably be popping up. For H265, we need to learn some more extra options. This topic can be confusing, so it's important to learn the difference. 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. And embedding it to the project with this html getting the best possible result. How can I recognize one? You can speed up and slow down encoding ruins presets. Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. Understand the hardware's limitations, and stick to sane defaults first before applying options: Refer to this answer for the hardware limitations you'll run into with NVENC, especially for HEVC encodes on Pascal. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? 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. Privacy Policy. Asking for help, clarification, or responding to other answers. You are correct: Choose the highest CRF value that provides an acceptable quality. This should work in your command line. Adding -crf 0 is not required. FFmpeg commands I using are the following: I used 30 as CRF for testing purposes because the artifacts are more visible :). hevc_nvenc option information. Maybe something more visible at lower bitrates? Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. 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.
