Video Ads: what network to use to make the most money?

Hi guys,

I want to let the user watch a video and get rewarded with X number of my in-game virtual currency.
A lot of services do that : Sponsorpay (BrandEngage), SuperSonic, Tapjoy etc.

My question is : which network overall pays best?
Most importantly: is there a mediation platform that let me integrate 1 SDK which integrate all the previously mentioned network?

All your experiences are very welcome.

I think Tapjoy has less video ads. I have integrated tapjoy in couple of my apps, so I regularly check whether they have new CPI campaigns or videos. They mostly have 1-2 video ads for couple days, then again none for some more days (for Germany)

They pay 1 cent per video.

Don’t know about the rest
