There are two most popular tools for video optimization -Handbrake andffmpeg. Encode some random segments from typical inputs. rev2023.3.1.43269. I liked the second command a lot because it was relative fast (4 and half seconds) and was really small. 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. What are the best settings for me to use when encoding x265 videos? Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. The CRF videos were done via Handbrake using x265 10-bit, whereas everything else was done via ffmpeg using x265 or x264 8-bit. -vf - the option for passing filters to ffmpeg. Applications of super-mathematics to non-super mathematics. @llogan. Great explanation. https://www.youtube.com/watch?v=bzgFL-gNF9g. (d). H265 Settings exclusive to H.265/HEVC encoding. 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. Since bitrate = file size / duration: You can also forgo the bitrate calculation if you already know what final (average) bitrate you need. Could the loss of quality be caused by VLC and its experimental support in deconding h265? Even thought the file size was much larger for the CRF 16 Medium encoding than it was than for the CRF 18 Slow! Does With(NoLock) help with query performance? Note: Windows users should use NUL instead of /dev/null and ^ instead of \. I hope you found this information as useful as I did, if you have any thoughts or feedback please let me know! The honest to god true answer is it depends, however I find that answer unsuitable for my own needs. YouTubes suggest guidelines for bitrates. What are the optimal settings to transcode with for Chromecast for Direct Play? But i don't think that I am doing it in the most effective way. -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. Why did the Soviets not shoot down US spy satellites during the Cold War? Powered by Trac 1.4.2 Well well wishing well, that is even more definitive. Generated via Python and matplotlib (Click to view larger version) Here we can see x264 has a much harder time at lower bitrates. Whereas FFmpeg can deduce the required output format of a file depending on the selected extension of the output file, it is recommended to explicitly declare the output format (through the -f option) so that extra options can be passed to the underlying muxer if needed, as is often the case with streaming formats such as HLS, mpegts and DASH. The results were surprising to me to be honest, I was expecting medium to have a better margin between fast and slow. Definitely not for archiving. 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.

Is Koestler's The Sleepwalkers still well regarded? 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. In this case, you are using two different encoders, so you get different bitrates. Most time effective web format for converting h.265, The open-source game engine youve been waiting for: Godot (Ep. You canread thisdoc for more info on this. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? Default psycho-acoustics tunings on x264 are much more mature and balanced for perceived quality than x265. The number of distinct words in a sentence. Choose a tune (optional). 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. Attempting to do so will result in encoder initialization failure. Handbrake 1.2.2. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? 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.
