I'm working on a few tests with footage with speed changes/ramps, and media managing. What I've found is that when copying (duplicating) files, the speed changes in the new media managed sequence stay true, as long as I don't add handles. When I do that, the speed change slips a little, especially when you have a variable speed change.
These tests were done on Apple Pro Res quicktimes. 2 things that I'm wondering though too is:
1) Does this work for quicktime wrapper files? Specifically, Apple XDCam EX files from a sony f3?
2) I did these tests on FCP 7. Is there a difference with FCP 6?
The media manager is also refereed to as media mangler. Be careful. You should only use the option to "copy media to location". This is non-destructive. All other options are destructive and could destroy your entire world if you are not fully educated in MM
