I have a few digital camera movies recorded in MJPEG that are taking a few GB of storage space. I would like to better compress them, but losing as little detail as possible, or none.
Since MJPEG doesn't compress across frames, I think that any modern movie codec would do a better job, wouldn't it?
Would the following ffmpeg command do what I expect?
ffmpeg -i input -c:v libx264 -preset veryslow -qp 0 output.mp4
