It would be something like this:

A theme is made and everyone will make a video based on the theme with a song of their choice. And then we will vote for our favorite! :)

i was thinking maybe we could have a youtube channel were the videos would be posted and everyone could see them there! ;-D

I wouldn't necessarily say that it sounds boring, I'm just not sure how practical it is.

A) It sounds like a lot of work, for a contest
B) I'm not sure how many video makers we even have here

...so for mainly those two reasons, I'm not sure how active a video-making contest would be. But I guess it's worth a shot. I don't know how to make videos, but I'd gladly vote!

I am a video maker but I don't make so much videos lately
