The way you are using your macro doesn't make sense to me. Do you want
ffmpeg-cut-clip to define a command which runs ffmpeg (in which case,
maybe it should be a macro), or actually just run the ffmpeg command
(in which case, maybe ffmpeg--comand-macro should not be a macro, but
rather a function (and probably called something like
ffmpeg-run-command instead))?
