When using DIVO there are no limitations concerning the lenght of video segments. You feed
it live video, which may be produced by a camera, a betacam recorder or any other video
source of your choice. You will simply need a digital video feed.

Sirius does the same as DIVO, but in a different way. We used the SIRIUS board as well as
the DIVO board.

This I have not tried, but if this works you will need A LOT of disk space.
