  • Ffmpeg : How to transition 2 videos together with a custom alpha channel video

    9 janvier 2023, par Daniel Enrico Botta

    I have these files :

    


      

    • 1.mp4, 2.mp4 (video files)

      • 


    • wipe.mov (alpha channel wipe)

      • 


    


    I want to use the wipe.mov as a transition between 1.mp4 and 2.mp4
The wipe.mov should replicate the same feeling as the xfade=transition=wipeleft with the only difference that it should use wipe.mov as input

    


    I have tried to use alphaextract to extract the alphachannel from the wipe.mov and this seems to work well.

    


    The problem is I can't figure out how to overlay and make transparent the correct portions in order to make this.

    


    Unfortunately xfade does not accept a video as input... I had tried something like this :

    


    ffmpeg -y -hide_banner -i 1.mp4 -i 2.mp4 -i wipe.mov -filter_complex \ "[0:v]settb=AVTB,setpts=PTS-STARTPT[v0];[1:v]settb=AVTB,setpts=PTS-STARTPTS\[v1]; \ [v1]scale=1280x720,format=yuva420p,alphaextract[alpha]; \ [v0][alpha]xfade=transition=custom:duration=1[out]" -map "[out]" output.mp4

    


    Does anyone know a way to make this work ?

    


    I have also been looking into lumakey...

    


    UPDATE :

    


    this is what I want to achieve :
