[FFmpeg-user] Reducing video file size

[Morten W. Petersen]

There are different sources, with varying existing encodings, and
resolutions. So those numbers were just thrown out there.

How about 100KB per 10 seconds, or 1MB per minute? What's possible to
squeeze in, or out there?

Regards,

Morten
