I'm still on the fence but leaning heavily towards hvx. nonethless, i have a need to shoot a lot of static talking head interviews in front of a green screen. it's my understanding that the jvc hdv codec can be downconverted to a nice 4.2.2 SD picture which makes me think a good key should be possible. but at the same time the jvc hd codec would be in 24p right? i don't really want that, the rest of the footage is standard 30i. but 24p is most apparent only in motion right? so would a 24p talking head greenscreen shot look significantly different than a regular static 30i or 60i shot? or are all my assumptions wrong and should i just give up.
