If its a video over 15 minutes, created by 1 team, then it'll go with the regular full lengths. If There are 2 teams involved then it goes under "Big Collaborations" (Big collaborations can be under 15 minutes). If there is no team involved, just a bunch of randoms, then it goes under "Big Collaborations". If its a video under 15 minutes (but at least 5 minutes), created by 1 team, then it can be considered a short film. I would start a short films list, but I don't know too many.

And I hate wegame too. It's slow...
