I will soon embark on my first proper project using FCS. Firstly, in terms of drive usage, is it best to use the scratch disc for that alone and keep the project files on the system drive or is it best to run everything from the scratch disc? Secondly in terms of mixed footage types: the film will be shot at the end of the week on a Sony PMW-EX1 in 1080p25. We already shot some footage a few weeks ago, alas this was mistakenly shot interlaced at 1440x1080i50. What would be the best way to go about combining these two sets of footage? Should I de-interlace the 1080i50 stuff first or just drop it all into the timeline and allow FCP to deal with it? Many thanks in advance.
