what's the max duration of video that can be uploaded?
Hi mikes, David
The video can be anything the contestant wants it to be. At a minimum it should show the design working and explain how the design works (high-level).
The community members will be viewing these videos and voting for them. So, you might want to think about what you would find interesting if you were a viewer.
Most videos is anticipated to be between 5 and 10 minutes.
