So I have a snippet from a bash script that overlays a transparent image watermark onto a video file, like this:
/usr/bin/ffmpeg -i input.mp4 -i out.png -filter_complex "overlay=10:10" /outputfolder/output.mp4
Works beautifully, and fast.
What I really need though, is to have the watermark only show up at the start of the video, and then every 15 minutes through the video afterwards, for 30 seconds at a time.
Is this possible without multiple passes?
Thanks in advance for all the help!
