I'm looking to put together a tutorial discussing fundamentals of Blues and Swing partner dancing. I have the raw source material. I'd like to change the background, change the attire of instructors (myself and a friend), and fix up other issues (dead space, umms, and other gaffs). The footage is about 22 minutes, and can be split into 5 different segments of about 3 - 4 minutes each.

I'm running Arch Linux and would rather not install DaVinci Resolve, but Blender would be fine for the non-linear video editor.

My plan is to use ChatCut to trim and split into the different sections. After I have the five segments, what would you suggest for swapping the background (environment) and attire? There are two simultaneous camera shots (front and side) that I'd like to stitch together as well.

Any suggestions? (Paying someone a couple of hundred $CAD to take this task off my plate would also work.)
