A real line test! Finally!

So I've finally managed to get into a studio and capture my frames for the first proper line test of the animation. Normally I would prefer to get this done earlier than 629 frames in, but whatcha gonna do...? Luckily, my instincts seem to have served me pretty well whilst drawing and I've only got a few timing discrepancies that I need to sort out. 
The start of the grid formation in the beginning of the film and some transitional sections are far too fast for my liking but they can be easily solved by drawing in extra frames and taking double captures of the frames where necessary. 
The parts I'm happiest with are the meteor at the start of the film and the hand at the end. I like that the arc in my meteor's trajectory worked out well and didn't just look like I couldn't draw in a straight line, because meteors apparently never come straight at the Earth because of the gravitational field <(Fun Fact) I think the hand worked out well because I really had to research how a hand moves by filming my own and studying it frame by frame. I feel the extra time invested there has paid off. 
The only thing that worries me about my animation is that after connecting two line tests together on Final Cut, the length was only 33 seconds. 629 frames caught at double capture in iStopMotion ought to create 52 seconds worth of film... Where have my other 19 seconds gone???? My only explanation for this is that perhaps iStopMotion was not capturing the frames as doubles. Need to investigate this, as it might affect my timing problems in the animation.
