I know the Decklink studio does live SD keying but I have a few questions.
1. Our footage is HD-SDI, does the decklink card down convert and then key? SD monitoring is fine, I just need to know if the originating source can be HD or if we have to rent an additional HD -> SD inline converter.
2. How is the background footage added? I assume there is some kind of decklink software that will help feed it out? It will be still frames of 3d backgrounds.
3. How taxing is this on a computer system? I’ll be doing some initial color correction in Red CineX and doing file transfers as DIT. If the decklink card carries all the weight, great, if not then I’ll run a second dedicated tower.
