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.
