This will be a real dummy question about VS2018
When I'm creating a split screen, why it will be added to the Overlay tracks only? Yes, I can move the first track to main video track, but then I hit to interesting synchnorization issues: When I add something before the split screen section the main video moves forward, but others doesn't. But if I do have the split screen only on the overlays, the next video to be added on the main video track cannot be added after the split screen. That is forced to go to end of the latest video/photo on the main track.
There must be something simple, what I just don't understand.
