FFmpeg-Overlay-Deckkraft

Ich habe eine Folge von Frames, die ich zum Erstellen eines Videos zusammenstellen muss.

Bei einer Serie von Frames möchte ich ein Bild mit unterschiedlicher Deckkraft überlagern (den Animationseffekt einblenden lassen).

Die Deckkraft sollte in Bezug auf Zeit oder Bildnummer () variieren.

Versucht mit diesem Befehl:

ffmpeg -f concat -i input.txt -i inputImg.jpg -filter_complex "[1]format=argb,geq=r='r(X,Y)':a='T*alpha(X,Y)'[v1];[0][v1]overlay=x=70:y=100" -crf 22 -threads 2 -preset ultrafast output.mp4 

Ausgabe:

Das Ausgabevideo enthält jedoch nicht das überlagerte Bild.

Hinweis: Die Bildgröße und das überlagerte Bild haben unterschiedliche Abmessungen.
