[FFmpeg-user] Question about ffmpeg

[Marcus Johnson]

Your question interested me, so I googled around and found that FFmpeg can
in fact do this with Tile=1x2, although I'm having trouble getting FFmpeg
to work with the file names properly.

In a script I have on windows I use a cmd wildcard basically to insert the
same file name twice, but I'm not sure what the equivalent would be on OS
X/Linux.
