capture video no longer works in RTW after 1.3 (I think that was the patch that broke it). The easiest way to do it is to use a 3rd-party capture program to capture the film. The harder option, but the one that would give the best results quality wise would be to mod a RTW 1.2 to use EB units (I don't know if that would be allowed by the rules of the competition).
