Video is obviously going to be better than audio alone but not a prerequisite by any means. Audio alone is good enough .
New builds are highly encouraged but not necessary, use what you got.
Same for the media itself, new material is highly encouraged but if you have something that we haven’t seen or heard yet, it’s fair game as long as it fits the criteria? Minimum 2 track 1-4 minutes 4 minutes max… let’s raise it to 4 minutes if someone wants to to do a traditionally structured song.
We are refining the criteria for sure there will be hard lines but I don’t want to limit creativity too much just enough to make it challenging but

achievable.
You hit the nail on the head
2 tracks minimum do as may as you like.. is this you throwing your hat in the ring? Now this is getting good!
