Im making my first documentary and am about to purchase/rent/beg/borrow/ steal a hi def camera. A cinematographer told me that festivals only accept submissions shot in 24p. An editor told me thats bunk, that 24p needs to be tweaked for television broadcast, and that I should only shoot in 29.97, and only interlaced. Since I would like to make something that can be submitted to both festivals and tv broadcast, can someone tell me what I should be shooting in? Ive used the Sony Z1U and kinda like it, especially since I may be able to borrow it for free. Plus its tape, which settles my nerves. But it shoots i. Also looking at Panasonic AG-HPX170, but am nervous about working with memory cards. Let me emphasize that I am not interested in the super fine differences between the cameras, but just want to know which HD format is acceptable to both festivals and tv broadcast. But if you have a preference for user friendly HD prosumer camera, do tell!
