Would it be possible to have an export for the .recs in marbleblast?
My Idea is this:
The game would go and start playing the demo you recorded. It would stop (pause the video) 30 (this could be changed) times a second to take a screen shot. It would save these screen shots and put them together into a video at the end.
I think this would be possible because (don't quote me on this) .recs record which keys you pressed at each time, so all it would have to do is be able to count time later to know when to pause and take a screen shot.
this is just an idea, so it doesn't really matter if it doesn't work, it would just be good for us people with bad computers that can't record due to the badness of our frames.
