x265 (HEVC) basic encoder settings?
Hello. It's all too complicated for me. Could you just tell me what the basiс settings for encoding are?
For example:
Also, I'm not sure about the preset option. I tried comparing 2 short files with medium and very slow presets, and I only managed to gain 10 KB in size reduction with very slow one. Is it worth it to change it from medium if encoding for personal purposes?

You've got some learning to do
Maybe start here: https://trac.ffmpeg.org/wiki/Encode/H.265 A basic command that will give you decent compression for most content without getting too slow would be something like the following: Code:
ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 output.mp4 Code:
ffmpeg -i input.mp4 -vf scale=w=-2:h=1080 -c:v libx265 -preset medium -crf 22 output.mp4 I'd suggest determining whether the default medium is tolerable in terms of speed. Use the slowest preset you can stand, and then tune your CRF value. |
