How do I create such a file?
Can I edit both video streams in cin?

It is extra work that results in a video that makes me sea sick. maybe with
enough work it could be done so that it both looks nice and you don't loose any
detail. Before I did that much work I would increase the res of the camera
footage and cut back and forth between the two. This might make a considerably
bigger file (how much bigger, and how big is too much is to be seen) but it is a
more acceptable work/results ratio.
But putting both streams into one file and having the player deal with it is
much more preferable.
