I'm thinking about making the jump to a 7D in the coming weeks/months (depending how soon I can rob the local bank). At the same time, as a student who wants to get into the film industry, I really need to be versed in videography. I'm trying to look up the answers to my questions, but I'm having trouble finding them.
I want to know, how long can you shoot record video for in a 7D? Can you keep recording until you run out of card space? How much runtime would be allotted if you shoot 1080 30fps video in a 8 GB card? 16? 32? What kind of CF card is ideal for shooting HD video?
In other words, I want to know how feasible it is to compile recorded clips from the 7D in a short film. I'd have a hard time if I have to buy 10 CF cards or buy a laptop to carry around with me as I shoot various places.
