We are planning on using the HVX 200 to shoot a couple of shots to be added to a P.S.A. that was originally shot with the Panasonic Varispeed camera in 720p. The P.S.A. was finished and colortimed in Digibeta. We would be adding our HVX shots to the Digibeta master. My question is, seeing as how our end product in Standard Definition, should we shoot in 720p or DvcPro50?
