After seeing numerous different techniques through google searches, I decided to ask you guys... What can I do to optimize performance with FCP while working on 1080 24p 5D Mark II .mov files? My first attempt resulted in FCP telling me my sequence settings did not match clip, and asking me if I wanted FCP to automatically match the sequence settings to the clip, so I said yes. Works fine for cutting and chopping etc, but whenever I add even the most basic motion or transition it wont play back without rendering... very time consuming. I read alot about transcoding into Apple ProRes 422, is this sometihng I should be doing? Thanks guys.
