Okay, I got completely lost looking through your blend file, especially since there were no textures included. You’re probably ten times better at blender though, because half the time, I didn’t know what the stuff you were using did. So it was easier just to redo the whole thing. I tried to keep the basic scene the same, and jazz it up a little. Well, I didn’t have any textures, so you might want to add those too. Anyways:
-Background torus stuff has not been animated yet. Just add some random rotation. It’ll always render behind the pillar thingy, so don’t worry about it getting in the way.
-Textures, as I said before, need to be added.
-Should render in a minute or less on your machine.
-Camera movements aren’t animated, just import your curve path from your original file.
-The video screen things have a trackto constraint, so if you want it like it was originally, just take that off.
I don’t know about the green color scheme though. Not very sport-like. You might want to change up the materials a bit. And my style of stuff isn’t really sporty in general either, so you might consider toning it down a bit too. Anyways, hope that helps.
