Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (360p.m3u 8) has not been used for any stream. As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). ffmpeg needs to be built with the --enable-gpl --enable-libx265 configuration flags and requires x265 to be installed on your system. The CRF scales for x264 and x265 do not correspond. CRF is the best of both worlds. Use the -g 1 option for FFmpeg 4.3 and newer or if you're using a build from the git master branch. Well, the size was the same (7,7MB, instead of the 3,8MB using the ffmpeg -i without any other option), but it was fast. 28 and 23 are the default CRF values of x265 and x264 respectively, hence the supposed equivalence. 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: 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. What is the potential range for a good CRF value? Pythons New Structural Pattern Matching! For more information, please see our On my computer (a fairly good laptop) it usually takes half the video playtime to convert into a mp4 using a generic ffmpeg command that i simple copy and paste from stackoverflow. Could very old employee stock options still be accessible and viable? 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. The original was H.265 encoded with a .ts extension. By Edgewall Software Privacy Policy. Older versions must use -x265-params keyint=1. 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). For some videos, you can try using the low resolution option, but on retina screens, it could lead to a blurry picture. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. See FFmpeg Wiki: H.265 for more info about those options. Profiles can be set via the -profile:v option, similar to libx264. 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. (d). What are some tools or methods I can purchase to trace a water leak? Constant Rate Factor over Average BitRate, Discover AWS State Machines using Python Lambdas for an ETL process. WebM is an open, royalty-free media file format designed for the web. The difference between the input and the output is practically non-visible for 1080p videos. 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. 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. is it worth to spend more time to encode slower preset? Encode some random segments from typical inputs. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Because if every frame was that good, we shouldnt need more than 6Mbps x265 or 10Mbps x264 4K video. Put simply, the closer the result is to 1 the better. Afterwards compared them to the original using the Structural Similarity Index (SSIM). (c). 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. So using veryslow is more wise. 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. Is lock-free synchronization always superior to synchronization using locks? How do I speed up the encoding? Centering layers in OpenLayers v4 after layer loading. 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 factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? rev2023.3.1.43269. 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.

In this test, I encoded all videos with ffmpeg using the default presents. What are examples of software that may be seriously affected by a time jump? We haven't used it in VP9 WebM because its architecture does not require this and always guarantees progressive loading. Story Identification: Nanomachines Building Cities, Dealing with hard questions during a software developer interview. FFmpeg best settings to encode Blu-Ray. 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). Super User is a question and answer site for computer enthusiasts and power users. 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. Ive got the right version of FFmpeg with libvmaf but am having a hard time getting the right CLI parameters. -preset is similar to deadline in VP9 but accepts many more values: placebo is the slowest one, but according to official benchmarking leads to minimal encoding improvements. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup.

Easiest way to remove 3/16" drive rivets from a lower screen door hinge? Ive specified it to 3x the 8Mbps (so 21M). Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? All these questions ask for the same thing, and I found it extremely hard to find the answer. Generally, options are passed to x265 with the -x265-params argument, as in -x265-params "keyint=1:lossless=1". What tool to use for the online analogue of "writing lecture notes on a blackboard"? 3 seconds at the start is nothing as long as the movie plays fine. Centering layers in OpenLayers v4 after layer loading. Not sure if theyre agnostic of resolution. Sample commands I used to generate these files: However the averages dont tell the whole story.

Planned Maintenance scheduled March 2nd, 2023 at 01:00 AM UTC (March 1st, We've added a "Necessary cookies only" option to the cookie consent popup, How to specify CRF quality settings for different encoding software, Trying to sync audio in mpeg2 video whose video freezes first 8 seconds in playback, FFMpeg concat demuxer corrupted output (freezed video on some concatenated parts). CRF works just like in x264, so choose the highest value that provides an acceptable quality. The open-source game engine youve been waiting for: Godot (Ep. x265 CRF 28 is supposed to be equivalent to x264 CRF 23. As with CRF, choose the slowest -preset you can tolerate, and optionally apply a -tune setting. Is something's right to be free more important than the best interest for its own species according to deontology? 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. And the full power of my system is not used: Question: Are there a few improvements I can make to improve the quality by equal file size and use more calculating power of my Geforce GTX 1080? 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). To learn more, see our tips on writing great answers. Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. You can speed up and slow down encoding ruins presets. I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). Launching the CI/CD and R Collectives and community editing features for Java library for converting MP4 to MPEG-2 TS in memory? Here is the order in which you have to pass arguments to FFmpeg: (a). For two-pass, you need to run ffmpeg twice, with almost the same settings, except for: For libx265, the -pass option (that you would use for libx264) is not applicable. Declare your inputs. Learn more about Stack Overflow the company, and our products. Acceleration without force in rotational motion? How can I recognize one? Note that when using faster presets with the same target bitrate, the resulting quality will be lower and vice-versa. 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. 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? shouldnt slower preset produce better picture quality? Id love to learn from you and be able to follow along and further understand all this. Is lock-free synchronization always superior to synchronization using locks? For streams, use the URL and if needed, prepend extra flags (such as buffer sizes) as needed. But x265 is not yet as mature in its development as x264, so take that CRF equivalence with a pinch of salt. 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. Famous codecs are H264, H265, and VP8/9. rev2023.3.1.43269. What CRF or settings I should choose for h265 in order to achieve a similiar quality of h264? Now that it is clear, the next important thing to learn is that not every codec is suitable for every video format. In this data set, slow is the clear winner in multiple ways. ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless. First thing I did was to chop out a minute segment and promptly remove the HDR. What would be the most time effective format and how to convert a raw h.265 video to it? 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? 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. 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. Thank you very much. The most widespread scenario for this one is scale. 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. Was Galileo expecting to see so many stars? A minute of 1080p video takes up ~150MB of storage, and double that for 60fps mode or 4K. Have you seen the h264 & h265 pages? (f). Still a vlc bad decoding + libx265 too young? Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. I did three CRF videos first, at 22, 20, and 18, then using their resulting bitrates created three ABR videos. It only takes a minute to sign up. 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. Think of video format as a container that defines file structure for carrying video and audio streams. To some, including myself, it could be worth the extra 4000kbps jump from CRF 22 to CRF 20. Could the loss of quality be caused by VLC and its experimental support in deconding h265? 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. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. You can indicate this by, i can link the answer to the other question. 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. Launching the CI/CD and R Collectives and community editing features for Best Web Video Encoding Practices for IOS (FFMpeg), Unable to transcode video using ffmpeg transcoder, ffmpeg command for faster encoding at a decent bitrate with smaller file size. The command I use boils down to ffmpeg.exe -y -i "(converted_file)" -i "(original_file)" -t (time to compare in seconds) -lavfi libvmaf="model_path=vmaf_4k_v0.6.1.pkl:log_path=details.txt;[0:v][1:v]ssim=1" -report -f null -\n. Also, I raised a flag to mark it as duplicate. 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. You canread thisdoc for more info on this. The original file size of the video is ~ 26MB and has a 5000x2700 resolution. 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. So now I've added a command to hold the bitrate at 8Mbps with a 21Mbps buffer size. 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.

To subscribe to this RSS feed, copy and paste this URL into your RSS reader. To know more about this, check out a wonderful demohere. Anything from 18-40 could give a very decent quality level. 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. Activating support for hardware acceleration when building from source requires some extra steps: Clone the FFmpeg git repository https://git.ffmpeg.org/ffmpeg.git I have read that previously, Chromecast used to limit playback at 11 Mbps. 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. I may mix it up myself in this article, dont worry about the letter, just the numbers. Making statements based on opinion; back them up with references or personal experience.

When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. ac3 should give you a 15%+ boost in speed. I started with a 4K HDR example video. The Compilation Guides show you how to do that. How to make PNG video render into 10bit h.264 matroska/avi file? Apple brought WebM support since macOS Big Sur to Safari on desktops, but to this day failed to make any progress on its mobile version. If so, what would the best solution? But the quality is not as good as expected. Here we can see x264 has a much harder time at lower bitrates. Making statements based on opinion; back them up with references or personal experience. However, there is still a solution. [] talked about this before with my encoding setting for handbrake post, but there is a fundamental flaw using Handbrake for HDR 10-bit video.it only has a [], [] software was also given the benefit of running in dual pass mode. Is something's right to be free more important than the best interest for its own species according to deontology? Which is very similar to others results as well, so Im personally sticking too it. Powered by Trac 1.4.2 Then I recently read YouTubes suggest guidelines for bitrates. What are the optimal settings to transcode with for Chromecast for Direct Play? 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). Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! So lets take a step back and look at the lowest 1% of the frames. ffmpeg - Read raw Data instead of converting to different Format, What is the fastest method to compress videos before sending in React Native Chatting app. Because if every frame was that good, we shouldn't need more than 6Mbps x265 or 10Mbps x264 4K video. Thanks for contributing an answer to Stack Overflow! Attempting to do so will result in encoder initialization failure. 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. 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. Start by understanding the encoder's options. Convert ffmpeg encoding from libx264 to h264_nvenc. Suspicious referee report, are "suggested citations" from a paper mill? 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. Keep in mind Im talking exclusively of x264 level 5.1+. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. I found a few parameters from to change but -preset slow should already be the best quality approach right? 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. Is this enough, or should I take some other things into consideration as well? How to increase the number of CPUs in my computer? 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. I believe that the last value of 31.6 Mbps is exceeding the capacity of the Chromecast v2. Should I include the MIT licence of a library which I use from a CDN? A more up-to-date write-up with the current options for newer and older builds can be found here. Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. Slower = better video quality and compression. Scroll down to the bottom to see notes on the performance impact of presets with this particular encoder. Thankfully there is a simple answer. So lets get a little more apples to apples. 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.
