I totally agree on the WD player. If you’re going the blu-ray route, make sure you test the disc on the same player that will be used for the presentation.
First, make sure that you have not collapsed the multiclip. Then double-click on the multiclip in the timeline to bring it back into the viewer, and select “Open” again.
I’m totally with Barry on this one. It would be a great feature, and really should be there already. Even when using a camera assistant and log sheet, it’s easy to lose track, especially if you often delete bad clips.
