Goal I want to combine a few clips together, with a 5-seconds of intro text on each one. Create overlay text in GIMP I created some overlay text in gimp, then exported to png files. An example (Note the transparancy, and drop shadow): Trim clips to length Using the methods I’ve described in previous ffmpeg posts, I trimmed the clips, ensuring that there is at least five seconds of lead-in on each clip for the text.
