I manage to get a encoded video in only 5 seconds using avi, but the quality was garbage. 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. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? In our case it is 3840px width. In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. ffmpeg -c:v libx265 -preset fast -crf 28 -tag:v hvc1 -c:a eac3 -b:a 224k -i <source> <target>. For this, you can use -c:v flag. (c). as in example? 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. Is there a more recent similar source? The quality difference between llhp and llhq as measured by Netflix's VMAF is virtually negligible, yet the encoder's performance boost (over ~30% on my test bed) with the former is definitely appreciable. x265 CRF 28 is supposed to be equivalent to x264 CRF 23. Call up the appropriate video and audio encoders, and pass necessary arguments to them, such as mappings, bitrates, encoder presets, etc. 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. I will make a few tests with h264. Why did the Soviets not shoot down US spy satellites during the Cold War? is there a chinese version of ex. See FFmpeg Wiki: H.265 for more info about those options. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. How do I avoid objects having flickering edges when I encode a screen recording to mp4 using x264 and ffmpeg? Centering layers in OpenLayers v4 after layer loading. YouTubes suggest guidelines for bitrates. Find centralized, trusted content and collaborate around the technologies you use most. 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). Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. 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. Does Cosmic Background radiation transmit heat? 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. 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. Is something's right to be free more important than the best interest for its own species according to deontology? For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. So where does that show up on our chart?

Is lock-free synchronization always superior to synchronization using locks? Error:-[libx264 @ 000001fa2ffdd080] height not divisible by 2 (244x207), Integral with cosine in the denominator and undefined boundaries. If you wish to master the tool, you will have to learn how to use flags. 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. Keyframes need more data then other frame types to avoid pulsing poor quality keyframes. 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. Slower = better video quality and compression. I mean there are many improvements that have been made in NVENC and NVENC HQ should be equal quality compared to default x264. rev2023.3.1.43269. 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. Not the answer you're looking for? Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Also, I find it much easier to share single ffmpeg commands across the team instead of showing where to click things in Handbrake. You can remove this scale=858:482: from my scripts. 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 dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? The number of distinct words in a sentence. Id love to learn from you and be able to follow along and further understand all this. Find centralized, trusted content and collaborate around the technologies you use most. shouldnt slower preset produce better picture quality? 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. 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. 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. You canread thisdoc for more info on this. Asking for help, clarification, or responding to other answers. So using veryslow is more wise.

When you omit this option, ffmpeg uses -crf 32 for VP9 by . At what point of what we watch as the MCU movies the branching started? We have some hard date, lets use it. If you require interlaced encoding support, please switch to Pascal or older SKUs instead. Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git Applications of super-mathematics to non-super mathematics. Open a 2nd command line and encode another .ts at the same time. How to increase the number of CPUs in my computer? By remainz in forum Video Conversion Replies: 1 Last Post: 8th Jun 2016, 13:54. Epic! 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. What you want is a min quality level at resulting in a variable bit rate. Another flag you can pass is -movflags faststart. Then I ran multiple two pass ABR runs using ffmpeg for both x264 and x265 using the same target bitrate. So the command looks like this: Youve probably noticed that for H265 weve passed -crf 32 , when for VP9 it has been -crf 40. WebM is an open, royalty-free media file format designed for the web. But based on just the average, slow was the obvious choice, as even bumping up the CRF from 18 to 16 didnt match the quality. I'm doing some experiments with HEVC x265. The SSIM result is done frame by frame, so we have to average them all together to see which is best overall. Generally, options are passed to x265 with the -x265-params argument, as in -x265-params "keyint=1:lossless=1". 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. There is currently a serious lack of data on compressing 4K HDR videos out there, so I took it upon myself to get learned in the ways of the x265 encoding world. These gains will be most pronounced at resolutions of 1080p and higher. 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. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? However, I head that this cap was removed. Should the results be the same, relatively? 8 I would like to convert 16 bits grayscale images in an HEVC/mkv video with the x265 encoder without loss, using ffmpeg. 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. I may mix it up myself in this article, dont worry about the letter, just the numbers. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Could very old employee stock options still be accessible and viable?

Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. thank you, I'll try it now and feedback you later ^^, I use it to decrease scale. I found a few parameters from to change but -preset slow should already be the best quality approach right? is it worth to spend more time to encode slower preset? Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. Ackermann Function without Recursion or Stack. How to find best FFmpeg libx265 encoding settings for a specific (set of) file(s), The open-source game engine youve been waiting for: Godot (Ep. Is Koestler's The Sleepwalkers still well regarded? The number of distinct words in a sentence, Torsion-free virtually free-by-cyclic groups. Nothing to do specifically with libx265 included with ffmpeg See. Attempting to do so will result in encoder initialization failure. Something wrong with reddit clipboard. 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. Encode some random segments from typical inputs. Predictable file sizes are a priority. Should I include the MIT licence of a library which I use from a CDN? 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. What are the best settings for me to use when encoding x265 videos? 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? 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 Create an account to follow your favorite communities and start taking part in conversations. To learn more, see our tips on writing great answers. )Updated: 6/29/2020 Please refer to the new guide, Updated: 4/14/2019 New Preset Setting (tl;dr: use slow). 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). Use the -x265-params lossless=1 option. Is a wanted design with a bigger amount of CRF values or could be considered this way because libx265 is still not mature enough in ffmpeg? So lets take a step back and look at the lowest 1% of the frames. 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. 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. When the device you are going to watch it on doesnt support it. Those other encoders might be better - I haven't studied that PDF closely. 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. Acceleration without force in rotational motion? H265 Settings exclusive to H.265/HEVC encoding. 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. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? Why does Jesus turn to the Father to forgive in Luke 23:34? Using video for animation with proper optimization is always better than GIF and sometimes outperforms native implementations. (g). The short answer to the deviation from expected performance is that x265 is still under "heavy development". Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. Making statements based on opinion; back them up with references or personal experience. 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. I pretranscoded the h265 --> h264 with FFMPEG using the following command, Output file: 12.1 Mbps 1080p h264 7.1 AAC mkv. Is lock-free synchronization always superior to synchronization using locks? ), In pass 1, you can leave audio out by specifying, P. Hanhart et al., Subjective quality evaluation of the upcoming HEVC video compression standard (. 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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. But i don't think that I am doing it in the most effective way. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. 20 medium 66.884759 0.9598, 22 slow 67.187793 0.959167 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. 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. And bitrate directly correlates to file size. 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. Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? Would the reflected sun's radiation melt ice in LEO? The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. In ffmpeg documentation that you linked is said that x265 crf 28 is roughly equivalent to x264 crf 23. Do not leave these blank. If you are encoding to x264 or x265, encode to 10-bit if your devices support it. (h). 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. Learn more about Stack Overflow the company, and our products. I did three CRF videos first, at 22, 20, and 18, then using their resulting bitrates created three ABR videos. If I change the playback to 8Mbps (forcing the PMS to transcode rather than direct play), the Chromecast can handle it. So what *is* the Latin word for chocolate? 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. This topic can be confusing, so it's important to learn the difference. Choose a tune (optional). 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. Choose the highest CRF value that provides an acceptable quality. (As a heads up h.265 is the specification, and x265 is encoder for it. This uses the native FFmpeg AAC encoder, but under AAC you will find info about more options. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Thanks for contributing an answer to Super User! 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. Most time effective web format for converting h.265, The open-source game engine youve been waiting for: Godot (Ep. When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. Then in three years H.266 / VVC toolsets will probably be popping up. and our I tried to look up the documentation, but i simple don't have the multimedia background to understand it. This guide focuses on the encoder libx265 which can offer around 2550% bitrate savings compared to H.264 video encoded with libx264, while retaining the same visual quality. I started with a 4K HDR example video. Convert ffmpeg encoding from libx264 to h264_nvenc. Download the SSIM data as CSV. I use both as .bat files. 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? Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and The hardware encoders were set to use the [], [] Encoding settings for HDR 4K videos using 10-bit x265 []. I used a three minute 4K HDR clip, using Handbrake to only modify which present was used. 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. 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). By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. I use the monochrome12 profile. So what *is* the Latin word for chocolate? Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. That way I know I should never be disappointed. But after even a basic compression it cuts down to 1MB. By default, this is disabled, and it is generally not required to set a tune option. See FFmpeg Wiki: H.265 for more info. If we run the command above, it compresses the video down to 542 KB. It is not a royalty-free codec - perhaps, that is why the adoption rate is much less than of WebM's. Anything from 18-40 could give a very decent quality level. 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. Planned Maintenance scheduled March 2nd, 2023 at 01:00 AM UTC (March 1st, How do I convert 10-bit H.265 / HEVC videos to H.264 without quality loss? 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. Thanks for contributing an answer to Stack Overflow! In this data set, slow is the clear winner in multiple ways. The open-source game engine youve been waiting for: Godot (Ep. Applications of super-mathematics to non-super mathematics. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. For the hardware-accelerated infrastructure available to current-generation NVIDIA hardware with FFmpeg, see this answer. CRF is the best of both worlds. Unfortunately, the same can't be said about videos. Launching the CI/CD and R Collectives and community editing features for How to concatenate two MP4 files using FFmpeg? Still, we get a good idea of where these show up. Learn more about Stack Overflow the company, and our products. 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 dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? Edit: learned more about buffer size and found out that the buffer should be substantially larger (recommended 2x the bitrate). Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ? ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless. Handbrake 1.2.2. Thanks for contributing an answer to Stack Overflow! Even though it does cost double the time of medium it really delivers in the quality department. Why using b-frames does not reduce the size of my video (using ffmpeg and nvenc)? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. 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. First things first, this is NOT a guide for Dolby Vision or HDR10. @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. To learn more, see our tips on writing great answers. For the llhp and llhq presets, as well as other presets in use, you can also override the in-built rate-control methods by passing the -rc:v arguments as exposed by the encoder options. ffmpeg -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. Not the answer you're looking for? It is less efficient in terms of optimization and does not have Constant Quality mode (-crf) and presets we used in the previous example.

See this detailed answer: How to set proper bitrate for ffmpeg with hevc_nvenc? Now I know that x265 can be around 50% more efficient than x264, and that YouTube needs it higher quality coming in so when they re-compress it it will still look good. Also h264 is faster to encode that h265, but again it will impact 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.
