Doing a multi-cam shoot incorporating Sony HXR-NX30U with my JVC GY-HM700. Do I need to select recording bit rates of each camcorder to be as similar as possible? Looks like a setting of 35 Mbps on the JVC and 28 Mbps on the Sony. Does it or will it make a difference? Secondly, should I avoid recording 1 cam interlaced and the other progressive? Unfortunately the final product will be delivered mostly on standard definition DVD.
