ffmpeg export without color loss
27 décembre 2020, par serI'm trying to add a watermark to a video through ffmpeg, but all the exports result in loss of color information. I would like to retain the same color information as the original video, how do I do that ?


Currently, I use this code :


./ffmpeg -i input.MOV -loop 1 -i logo.png -codec:v libx264 -crf 18 -preset medium -filter_complex "



I realised the only way to not lose the color information is to set -crf to 0 and -preset to veryslow, but it results in a really large file size. (2 times the size of original video, which is not effective)


I also get this error when I run ffpmeg :


[swscaler @ 0x117577000] deprecated pixel format used, make sure you did set range correctly



See Image comparison here — the blacks on the export were not as "black" as original
