add same effect with different settings several times to an input-file

Post by Bamba675 » Sun Apr 28, 2019 8:30 am

I'm trying to remove (for example) the greenscreen and the bluescreen of a video. To do this, I have to use FFMpeg.

I already tried this one:

Code: Select all

ffmpeg -i background.mp4 -i greenbluefootage.mp4 -filter_complex "[1:v]chromakey=0x67FF00:0.1:0.1,chromakey=0x0061FF:0.1:0.1[aa];[0:v][aa] overlay" output.mp4
But there, just one color removes. Why not both?

I simply want to remove both colors (make them transparent) so the background can shine through.
