Its not too hard at all in after effects at least. You just import image sequence and when you load the first image it pulls the whole set for one eye. You just make a square canvase after that and put the left eye on top and right eye on the bottom. You can render it from here, but you have to use mp4 type formats for Googles metadata injector to work. Just go through the process once with a few frames, and the next time around will only take you like 10 minutes from AE to Youtube or FB.
