What cams are interchangeable?

[Chamber005]

In my webseries I use the HF200 set at a measly 12mbps (it's capable of 24) at 30p (it can go 24p). I'm curious how one knows if two cam's pictures are interchangeable. Do you go by mbps or some other factor?

Rather than going for an EX-1 when I try on my first short feature next year to coincide with the webseries, I'd like to just purchase another HF200 (or HFS100) and one or two GH1s (or GH2s if they exist by then). I feel like their combined attributes would bring together a pretty nice look overall and the three cams combined would be cheaper than one EX -- but I'm concerned about the two pictures lining up effectively.

Not sure what specs I should be focusing on...

Thanks!!

I suspect colour balance would be the most obvious difference. Frankly you'd need to borrow the camera for a day or two and try it on the kind of material you have in mind, to work out which is best for what and how they can each be adjusted to give a result which will best blend.
