Thanks, I will look into archives. Especially after I’ve split these videos up.
PROBLEM: I thought this was a good method, but it seems to be messing up for some reason. I have cut each file into about 10-15 shorter subclips. I use media manager to create new files of the sub clips. I thought that had worked for the first video. But for the second, it only created half the files, at random, and the durations of these new files did not match the durations shown in fcp. In other words, it had failed to work. Looking back at the first video again, I noticed that in a couple of movies, the durations had changed.
In other words, FCP doesn’t seem to be able to handle the big file sizes, or cutting large files down into lots of smaller ones.
So, at the moment I’m going back to the original movies, and using MPEG Streamclip I’m exporting selected areas of the videos. This is going to take me a long time (because that’s not a batch method). Any suggestions?
