I wish I wasn’t back on this thread but I am…
I don’t know what changed – suddenly the dropped frames are worse than ever. I have even opened old projects, none of which used dslr footage or gave me problems with dropped frames before, and I can hardly play a couple seconds without issues. Same thing if I start a new project and drop one pro res clip on the timeline.
This G-drive belongs to my employer; when I take my laptop home, I work off a smaller Seagate external (also firewire) and then Final Cut doesn’t give me much trouble – so maybe it’s a problem with the new external drive or the way it’s formatted?
