With a search on the internet I found I could put a picture into a
video with:
ffmpeg -i introductie.mkv -i Pictures/reiger.jpg \
-filter_complex "[0:v][1:v] overlay=W-w:H-h:enable='between(t,0,20)'" \
-pix_fmt yuv420p -c:a copy \
metReiger.mp4
But what if I would insert another picture at another time?
Or two at the same time? One top left, the other top right.
You can use two or more overlay filters in the filter chain:
ffmpeg -i introductie.mkv -i image1.jpg -i image2.jpg -filter_complex
"[0:v][1:v]
overlay=W-w:H-h:enable='between(t,0,20)'[a];[a][2:v]overlay=W-w:H-h:enable='between(t,21,25)'"
...
What I find strange is that the input video is 23 MB and the picture
is 302 KB, but the generated video is 42 MB.
You can for example specify the bitrate with -b:v
