I am trying to overlay a png image onto a series of images (a few hundred images), I will later take this series of images with the overlay and construct a movie out of the series of images. I don't know too much about ffmpeg and I have just recently started playing with it for converting and editing media files but I have found something that works for combining the png with one tif image:
ffmpeg -i my.png -i my.tif -filter_complex "scale2ref[i][m];[m][i]overlay[v]" -map "[v]" -map 0:a? -ac 2 output.tif
This is what I have so far, which allows me to overlay my png on a single tif image. I would like to do this for every single tif image that I have in my folder (hundreds) of tif images.
Is there a way to instruct ffmpeg to do such a process?
