I\'m trying to convert 200 .jpg files that were .ppm files into one .mp4 file.
In the same directory as the .jpg files, I ran this code:
convert -del
The proper syntax is:
convert src_file [options] dst_file
So in your case, it should be like:
convert movie.mp4 -delay 6 -quality 95 test*ppm movie_converted.mp4
