My goal is to get these into DNxHD so I can import them into DaVinci Resolve with no quality loss and the smoothest motion possible. I have AviSynth, Vapoursynth, Hybrid, FFMPEG, QTGMC and VirtualDub2 installed, but I'm lost as to where to go from here. I'm guessing each camera's files are different enough that I will need different scripts for each. I'm willing to listen and learn if someone could point me in the right direction.

edit: I know I will need to deinterlace footage from cameras 1 and 3. Ideally I'd like to end up with 59.94fps (or 60, as the case may be) files. I know that's asking for a lot from camera 2 though (15fps), in that case I'm guessing I'll actually need to drop down to something like 10fps to make it a little easier to look at. Something about the way 15fps handles motion feels almost like being seasick to me, not something I encountered on my old Lumix that shot at 10fps.
