I'm shooting a performance this weekend on my HPX camera. The guys who I'm doing it for are trying to get me to rent as little as possible. If I want to shoot in 720/30p, I have to rent another card or so, but if I shoot in 720p/30pn, I'll have to rent less as I can record far more. Can anyone tell me what kind of issues I may face in editing/DVD cutting/playback? I've never used this format before.
