I'm pretty sure that filming ahead of schedule was not allowed. The idea was to see what people can get together at the time of the round, otherwise you could just trawl the the archives, pick a snippet of something you like from whenever and throw that into the mix.
Who's to know when a piece of video was shot ? Thus you couldn't determine if it pre-date the start of the VF round or not.
Obviously videos should be original works, not just some cut of a previously released video. We probably need to make that explicit in the competition rules.http://virtualfreestyle.com/about-vf/competition-rules
