If you are trying to complete the 'fly by' video of your 3D model, for extra credit, and are having troubles with it, the issue is the default video codec. A codec is basically the algorithm used for the compression of the video. YouTube doesn't seem to like the default Microsoft RLE codec. I had to change the codec that I used to by Cinepak Codec by Radius. Then it worked like a charm.
I have attached two screen grabs for your review. If/when you get it to work, email me a link to the video. See you all bright and early tomorrow. I will bring donuts.
