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. FFmpeg commands I using are the following: I used 30 as CRF for testing purposes because the artifacts are more visible :). In the past, I went straight to Handbrakes documentation. Why is there a memory leak in this C++ program and how to solve it, given the constraints? Convert ffmpeg encoding from libx264 to h264_nvenc. This time with Pre-Analysis. Your mileage will definitely vary, based on your source content, filter chains in use, specific pltform configuration variables (such as your GPU and driver versions), etc. 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. Consider your encoding workflow and adjust as necessary. Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ? Choose the highest CRF value that provides an acceptable quality. If so, what would the best solution? Thanks @szatmary. So using veryslow is more wise. Theoretically Correct vs Practical Notation. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. So what *is* the Latin word for chocolate? What does a search warrant actually look like? They have some good detail on what things mean. 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. Okay, okay, lets back up a step and look at the bottom 1% again as well. 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? Connect and share knowledge within a single location that is structured and easy to search. See FFmpeg Wiki: H.265 for more info. I have always read to use Constant Rate Factor over Average BitRate for stored video files (and especially over Constant Quality). 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. 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. Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. nodejs ffmpeg play video at specific time and stream it to client, ffmpeg mp4 video cannot be played in old tv, Duress at instant speed in response to Counterspell. as in example? 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. Pass any arguments to FFmpeg (such as -loglevel to it directly) before declaring inputs. Not sure if theyre agnostic of resolution. Is this the best possible solution, or is there a better way of doing this? 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. (e). I don't want others to keep searching for the answer. In ffmpeg documentation that you linked is said that x265 crf 28 is roughly equivalent to x264 crf 23. I have read that previously, Chromecast used to limit playback at 11 Mbps. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Profile ( -profile) The profile determines which features of the codec are available and enabled, while also affecting other restrictions. Has Microsoft lowered its Windows 11 eligibility criteria? 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. The snippet above assumes that the input file is an MPEG2 stream. Even if your source video doesnt use the HDR color space, it compresses better. FFmpeg: For NVENC, what is a concurrent surface? 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. Note: Windows users should use NUL instead of /dev/null and ^ instead of \. It works if I specify the output bitrate, but I want to know how to figure out the proper bitrate? Should the results be the same, relatively? 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. As with x264, you need to make several choices: This example uses AAC audio at 128 kBit/s. Your video is 10 minutes (600 seconds) long and an output of 200 MiB is desired. FFmpeg commands I using are the following: ffmpeg -i input.mp4 -c:v libx264 -crf 30 -c:a copy output_h264.mkv and 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. Over 8 Mbps for most 1080p content with x265 is plenty good so you definitely don't need to use the slowest encoding settings. Still a vlc bad decoding + libx265 too young? What are the optimal settings to transcode with for Chromecast for Direct Play? Visit the Trac open source project athttp://trac.edgewall.org/, Last modified on Oct 5, 2021, 11:32:18 AM. This is best explained with an example. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? 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. The absolute path to the output file. Centering layers in OpenLayers v4 after layer loading. 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. Help with ffmpeg settings H265. The jump from medium to slow is very significant in multiple ways. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Note that hevc_nvenc will almost produce larger files than libx265 at a given quality because it not as efficient as an encoder. . 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 ? Well well wishing well, that is even more definitive. ffmpeg: Output mpegts with a single program containing 1 audio and 3 video, Set keyframe interval in ffmpeg when using nvenc. For better visualization, I am going to show you how applying different options to ffmpeg decreases the file size and changes the quality. Why using b-frames does not reduce the size of my video (using ffmpeg and nvenc)? Privacy Policy. Not the answer you're looking for? 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. 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. Here is the order in which you have to pass arguments to FFmpeg: (a). The bitrates are as expected, the higher quality it gets the more bitrate it will need. 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. ***### Encode video as x265 HEVC 10bit.ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv### Same as above, but as a two-pass x265 HEVC 10bit encode.ffmpeg -y -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=1 -an -f null /dev/null && \ffmpeg -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=2 -c:a copy "output".mkv. 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. The best answers are voted up and rise to the top, Not the answer you're looking for? Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. Use CRF 23+ for videos in 4K. See a list of available x265 profiles.

Providing tools to analyse, process, transcode, and deliver images and videos, on the shoulders of state-of-the-art cloud, media and AI technology. This uses the native FFmpeg AAC encoder, but under AAC you will find info about more options. 18 slow 68.298806 0.96016 Call up the binary. 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 open-source game engine youve been waiting for: Godot (Ep. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Depends on the encoder, the ffmpeg one I dont think supports 10 bit, but VCEEncC does. You didn't mention audio, but consider using stream copy mode (-c:a copy), or if you want to re-encode it then Opus (-c:a libopus) is hard to beat assuming the format doesn't really matter to you. Your inputs are already H.265/HEVC, so you can simply mux them into MP4 without needing to re-encode. Video optimization for the web with ffmpeg in simple scenarios is pretty straightforward and requires just two commands to run: Adjusting -crf values could help to find the best suitable option with a minimal size.

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. Do not leave these blank. At both CRF 24 and CRF 22, even the lowest frames dont dip below SSIM 0.95. (g). 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. Now this is an apples to oranges comparison. 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.

When the device you are going to watch it on doesnt support it. 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). All Rights Reserved. Both values result in a very similar bitrate for both videos, just a syntax difference due to different accepted number range. Epic! Their overall average SSIM scores were near as identical. Although I've been using Plex for years, my setup is far inferior to most of the people on this forum. ffmpeg has more video optimization settings available, such as Constrained Quality, Two-passes, Constant bitrate, and Lossless.

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. 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. The difference between the input and the output is practically non-visible for 1080p videos. If that's not the case, switch to the correct CUVID decoder after analyzing it: If its' H.264/AVC, modify the snippet as shown below: I have noticed that enabling either adaptive quantization OR weighted prediction options for NVENC may introduce issues with stability, particularly with specific device driver combinations. It is well known between pros that SSIM and PSNR are not good measures or SUBJECTIVELY PERCEIVABLE quality. Here we can see x264 has a much harder time at lower bitrates. 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. If libx265 is too slow use libx264 which is faster but file size will be bigger. Why are non-Western countries siding with China in the UN?
