I am learning DP, by basically throwing myself into it. Things are moving along peaceably.
Here's my problem--
I am working on a dance piece. No, no, that's not the problem.

I meet with the choreographer and we watch video of past performances of this work-in-progress in Cubase 5. Cubase permits cutting and pasting of video (though not exporting, saving or otherwise manipulating.) When the choreographer wants to insert or remove some time I make the corresponding edit in Cubase and play it back for her with the video. This confirms the edit and that we have both understood the same thing. I later can use these very rough looking edits to remind me of what to do, in addition to my my notes, of course.
This video cut/paste is not possible in DP, so my question is, can any of you recommend software that will enable me to insert or delete time in a video, then render it to disk so I can bring it into DP?
I tried to use MPEG streamclip to slice things up and then use multiple sequences in DP for each video clip, but this seemed too cumbersome, but that impression might have come from my lack of familiarity with DP.
Any suggestions on how to replace my old workflow with something that gets a similar result would be appreciated.
Many thanks,
Steve
