FFMPEG- Is it possible to overlay multiple images over a video at specified intervals?
Basic method is
ffmpeg -i video -i image1 -i image2 -i image3
-filter_complex
"[0][1]overlay=x=X:y=Y:enable='between(t,23,27)'[v1];
[v1][2]overlay=x=X:y=Y:enable='between(t,44,61)'[v2];
[v2][3]overlay=x=X:y=Y:enable='gt(t,112)'[v3]"
-map "[v3]" -map 0:a out.mp4
The last image will be overlaid from t=112 seconds till end of video.
