Decided to move the compositing for this shot from Kdenlive to Blender. Originally I created the 2 animations and the intervening cel separately and then put them together on the Kdenlive timeline, but I decided it would be a little neater to do the job in the Blender compositing file. Also, I just wanted to test doing it.
I've learned a few things in this process.
First of all, yes, I was definitely applying masks in an overcomplicated way before -- this is just another application of the "Alpha Over" node, which I've used before. In fact, the billboard masking I was using before uses the same method.
Also, I either never learned or forgot that it is possible to copy and paste nodes and collections of nodes with Ctrl-C/Ctrl-V even in 2.79 and even between different scenes. This saves quite a bit of time.
