Thanks for the replies!
Here’s a little more detail for you:
I first imported all the raw full HD footage into a FCP project.
Then I used media manager and re-compressed all the files down to DV-PAL (as this allowed me to use multiclip effectively), keeping the same file names.
I made a new project and imported all the re-compressed files and created my project under the sequence settings automatically detected by FCP when you drag and drop into timeline.
I’ve added text effects, multiclips and the final project is around 10 minutes long.
I now need to take this DV-PAL project and re-connect it with my original RAW HD footage. How?
The video was very helpful although I’m not sure if it’s exactly what I’m looking for to help my problem. I’m still a FCP beginner so sorry if there seems an obvious solution.
Thanks so much for your continued help,
Josh.
