Hi Ali,

It sounds as though you are working with both uncompressed Digibeta video and also compressed DVCAM video. If you ingest your DVCAM material via Firewire, then it makes sense to continue working with DVCAM for your effects, editing and grading to avoid unnecessary generational loss and long render times when moving to uncompressed and then back to DVCAM formats.

However if your DVCAM has SDI input and output, then it would make a lot of sense to capture to an uncompressed timeline via the DeckLink card and you can also capture your Digibeta material to the same uncompressed timeline. The great thing about uncompressed is that you can render it as many times as you like, add effects, transitions, graphics and text and there will be no generational loss of quality. Once you have completed all of your editing, you can then output your uncompressed material back to the deck via uncompressed SDI. Your DVCAM deck will record the video and audio back to the DVCAM tape format. This is particularly useful if you need to do a lot of editing where multiple levels of generational loss will become quite obvious when working with a compressed format such as DVCAM. Using an uncompressed timeline takes up more storage but guarantees that you do not lose any picture quality during your editing. Graphics and text remain sharp throughout the editing process and will not become soft before you master to tape. So the resulting master will look as crisp as is technically possible.

If your DVCAM lacks SDI connections, it might have component analog video and analog XLR audio. We have other models of DeckLink cards which can connect to both SDI decks and analog decks. The DeckLink Extreme and DeckLink HD Extreme are two such cards. The DeckLink HD Extreme also features HDMI input and output.
