is it possible to have other text blend effects in ffmpeg other than transparency ? eg multiply or difference
26 mars 2023, par shelbypereiraIn ffmpeg it is straightforward using alpha to set a transparency when using drawtext, but is it possible to have more complex effects ? eg if I want to blend text using difference or multiply ?


I am guessing it is not possible with drawtext directly is it possible to simulate this using other features of ffmpeg ?


The blend functionality is extremely powerful :
https://trac.ffmpeg.org/wiki/Blend


But I don't see how I can add text to a video with drawtext and use those blending options.
