A video I made to try out the Compositor2. While I do make music videdo’s where I use a split-screen layout to show multiple vids of me singing and playing music, this video is supposed to give the idea that I am in the same room, twice 
I speak Dutch in the video, but I also created English subtitles using the credits option.
I added a little backgroundmusic that I made by playing some chords on my keyboard (visible on the right in the background).
I even adjusted the brightness in the shot on the left to comply with the changing white-balance in the other shot, when my second me comes in and the webcam adjusts it automatically for that recording.
It makes the combined shots more unisome (is that a word?).
I love the compositor, though I noticed the offset of the source goes no further then 50%. So I wasn’t able to perfect the ‘trick with the mic’ as much as I hoped ; You’ll see that my left self takes the microphone from the part of the shot that is covered by the 2nd overlapping video on the right. I had hoped to apply 3 consecutive compositors to the right-side bit, to enable a shift in the split between Me nr1 and Me nr2 ; start with a 50/50, a bit more to the right when nr1 takes the mike, and a bit more to the left when nr2 takes it.
On the other hand, it’s cool that I can start the video by myself in the center of the frame, then shift aside, ‘gradient wipe’ the other shot into the right part of the video and let myself appear there as well. My wallpaper helps to conseal whatever you might see of the split line between both vids (if ever there is one).
Fun little experiment.
