Like an adult diaper, it depends. If I'm reading it right, you're going to
be greatly stretching out the Y-axis. Is that what you are wanting to do?
That would really distort the image.

One suggestion I have is to put your output file name in quotes
("video+audio2008.mp4"), use a \ character (video\+audio2008.mp4), or just
ditch the + character. FFmpeg and bash/sh/zsh/etc might not interpret it
the way you want it to.
