Greetings Carl and Paul, Thank you both for your advice. Paul, can you demonstrate how exactly to use the loop video filter? I have tried:
ffmpeg -i FILE.jpg -i FILE.mp3 -vf loop=loop=1 FILE.mp4 The result is audio with a black screen rather than with an image. I clearly have not understood the filter guide.
