Hallo,
I used Davinci resolve for the first time and I didn't care about the video bit depth value as I didn't know it does exist. My first projet has beem made with a bit rate of 10 which give me for a 50mn video a mp4 file from 14Gb.
Is there a fonction in FFmpeg to reduce the V.Bit Depth von to 10 to 8?
Thank you very much
Claude

Check zscale filter https://ffmpeg.org/ffmpeg-filters.html#zscale-1 - accordingly to some people it is faster, more accurate and more predictable than native libswscale.
