I’m trying make a video that includes a transition where one image fades into a different image. I would like to do this programmatically (as opposed to using GIMP or video software) so that the result is repeatable and shareable. My starting point is a set of Gadfly plots that I saved out as PNG and then combine into a video with
ffmpeg. So the fading could potentially be done either at the plotting stage before saving the images, or after.
Does anyone have any suggestions? Thanks in advance for any help!
