VV4. I captured 5 hours of video via 5 different clips. I watched all 5 clips in the trimmer window dropping markers and creating regions. All clips retained their markers with no problem.

Now, for some reason one of my clips no longer has ANY marker information! No files have been moved. The markers were there - I left for 1/2 hour - I come back and the markers are gone! All the other clips still have their markers but I have restarted VV4 several times and still Clip 3 has lost its markers.

Any thoughts? How can I make sure this NEVER happens again? This really throws a wrench in a what was a very smooth running edit.
