If you zip the video you can attach it that way. Or post the link to your saves sitch.

And upload the debug log.

Hmm, I uploaded the video, and it seems to have worked. I suspect your upload was interrupted. Can you just try it again here?

When you import a KML with multiple tracks, it currently assumes you want to use one of them as the camera and the other as the target (using the first two). This historically was the case, but not so much now.

I'll rework this so what happens is more intuitive and/or optional.
