How to re-edit and/or duplicate an in-progress edit with YouTube Video Editor After uploading a bunch of clips to YouTube, I go into their editor and begin making cuts, combining clips together, etc. The problem is, after I published it, there is no way (that I can see) to go back and open up that project in the Video Editor again to make changes to the edit.

This wouldn't be so bad if I also couldn't figure out how to duplicate an edit project. So for example, if Im in the middle of editing a bunch of clips together, named "Project 1", how could I think "Save as..." or duplicate that project to "Project 1b."

Any ideas? The google help center on this is pretty sparse.
The YouTube video editor is just not designed for this sort of thing - it has very basic functionality, just enough to allow you to tweak a couple of things. Once the edit is complete it has no ongoing concept of a 'project' - you just have a new video.

I would always recommend editing locally in a proper video editor and then uploading.
