  • ffmpeg add alpha to the video

    3 octobre 2014, par death_relic0

    Basically I have a video with a green background, and I mean a perfect green background (red = 0, green = 255, blue = 0) and I want to convert this to alpha (i.e add an alpha channel where 0 255 0 corresponds to alpha)

    I am very new to ffmpeg so I can’t figure this out. I am guessing it has something to do with the alphamerge option.

    THanks in advance
