Would this be possible to sort out in post? Disregarding how it would "look".
Could you edit and out put both with a satisfactory result?

The reason is that I have a superior (to theirs)NTSC cam and am planning to do a job with some PAL guys..

Can it be pulled off somehow?

Thanks.

You will have to convert to one format before importinng the footage to your timeline. The only problem you will have is the fact that you can't mix formats on the timeline.
