Hard to say without a shipping HVX200 to test. Remember it’s also Hidef vs. SD, 2/3″ vs. 1/3″ and also way better potential glass on an ENG style camera like the Sony, 24p vs. 60i ,etc. Pretty much Apples to Oranges.
Err- can you elaborate a little on what you mean? Motion control is normally what’s referred to when you’re talking about doing composites or multi-pass photography with a computer controlled camera. What aspect of this process do you wish to use Motion for?
Yes- native 16:9. It’s got a lot of other tricks up its sleeve for standard definition as well. For example- you can shoot 720p slow motion and automatically get a downconvert to DV on tape. That means this is the only SD camera that shoots true slow motion in camera.
