Combining footage from Different cameras

Hello,

I am having a problem that I would appreciate any help in solving. I am midway through a documentary film and am combining footage from two different cameras and could use some assistance in setting this thing up in final cut.

The first camera is a Sony HVR-V1u shot in 24p HDV 1440 x 1080 mode and the second is the Canon 5d Mark 2 shot in 1920 x 1080.

I am at a loss on the best way to combine the footage. What I have come up with is converting the 5d footage into pro res 422 LT changing the frame rate to 29.97. Then I convert the hdv footage to prores 422LT.

Any sort of assistance on this will be greatly appreciated. I am going to have about 200 hours of footage so I would like to go with the LT setting but am open to suggestions. The end use is a blu ray dvd so i really don't want to lose quality in the editing. I guess a big question is whether to degrade the 5d or to blow up the HDV? Any help out there?

Thanks,
Carlton
