Actually I wasn’t considering making the 1080 footage go to a bigger frame, perhaps I didn’t explain my situation clearly. And yes, it is Multicam project, as mentioned, but my concern is for the exported project where this difference between the cameras is sort of noticeable – but not too bad. What I was hoping is that someone might be able to suggest a Compressor setting (or some other utility) that would make the codecs and frame sizes closer to each other or maybe even the same before I reassemble the Multicam project and edit. As far as my inexperienced eye can see, the differences between the two video files are frame size and codec? It’s quite possible that I’m asking for the impossible as although I’m very much at ease with FCP, I’ve never noticed this rippling effect on the footage from my action camera before which is possibly due to the unique lighting situation? So, anyone got some Compressor settings suggestions…?
