Here's my TopGear spoof I did recently using some otherwise very boring footage of use driving!

Some of these shots has four concurrent PiP tracks.
I found the limiting factor was that because they were separate tracks it was hard getting them to move together
I'd prefer a way to move them together as single items then group them to move them
Hope this is useful
