There are firms out there like Jukin Media, Storyful, Rumble etc that will pay you a fixed amount or a percentage of profit if you allow them to promote your video (and make money from it). They have a wider reach and so your video has a better potential to go viral that way.
An exclusive license is like a network, you give them the exclusive right (except for yourself) to post, promote and make money from your video. In return you get 60-80% of the money they make.
A non-exclusive license gives them the right to promote your video to their partners and make money, but you retain the right to do the exact same thing with other companies. For this they either give you a fixed amount or also a percentage.
In the first option they gain control over your youtube monetization for that video, in the second option they don't.
Hope this sums it up shortly and correct

[DOUBLEPOST=1459201363,1459201233][/DOUBLEPOST]These are only videos that have the potential to go viral, vlogs and the sorts won't work this way.
