Ich habe in meinem Video eine grüne Überlagerung erhalten, wenn Sie den multiplizierten Mischmodus in ffmpeg verwenden

Ich versuche, zwei Videos mit dem Multiplikations-Mischmodus zu mischen. Aber ich habe im Ergebnis ein grünes Overlay erhalten.

Dies ist ein Bild, in dem ein Rahmen jeden Eingangsvideos und ein Vollbild der resultierenden Video ist Composition

Ich führe diese Befehlszeile aus:

sudo ffmpeg -y -i video_top.avi -i video_background.mp4 -filter_complex "blend=all_mode=multiply" -f mp4 -vcodec libx264 out.mp4 

Dies ist die ffmpeg-Ausgabe:

Ich weiß nicht, was falsch ist, und die Verwendung anderer Mischmodi brachte andere lächerliche Ergebnisse mit sich, wie beispielsweise eine rosa Überlagerung im Video.

Vorschläge werden dankbar sehr geschätzt.
