Front end version and ads

I am interested in getting this plugin but I have a presale questions.

I want to use this plugin on my contest website which allows people to upload videos from their phones to enter into competitions on my website.

This will mean that for one page, there might be about 30 different videos. My first question is, does this plugin have a front end part to it which allows my end users to be able to upload videos themselves without needing to go into admin?

My second questions is that adverts. I will be having different competitions and I want to put different adverts at the start of all the different videos that will be entered into the different competitions. Does your plugin have the capability to do that?

Please let me know soon as I am quite interested
