Very nice. I was recently look for something similar, but with support for markers (eg. add marker "explosion" to video XY at 2:14). Do you plan to implement such feature?

I didn't expect to put in markers ... though if adding tags is to become a feature, perhaps tags that correspond to time might be easy-enough.

The trickiest part would be the UI -- making it usable and elegant.

Perhaps those markings would visually fit nicely inside the filmstrip view.
