Well, I can ensure you that jury won't judge based on videos. I act as chairman and won't handle them the videos. Moreover, judges have great knowledge of the machine, their limitations, existing games and software and some of them even have collaborated on homebrew projects. As humans, they'll always be subject to their own preferences, but will have clear criteria to evaluate.
Anyways, I'm pretty sure that no single possible result will be agreed by everybody. That's live! It's tough!
