Video Ad Networks?
 

Does anyone know of any ad companies that pay to have video ads played before the user can view the content? I'm trying to come up with an alternative for a survey based content locker.

there are... if you use jwplayer checkout LongTailVideos (mainstream)

don't know if there are adult ones...

Thanks, I'll check that out. It's mainstream so that works but the videos aren't mine, they're embedded megavideo/vimeo/etc links (meaning that they use whatever player the scraper takes them from).

Anybody else?

Use vadplayer.com and you can put ANY kind of ads to the player. Pre roll, post roll, invideo text. It can handle any html codes, adserver scripts, or adnetwork scripts.

Exoclick in-Video ads can be set to Pre-roll, Post-roll, Inline(text or banner) or on Pause. Hit me up if you have any questions.:pimp

we have developed something for this using our content.
Have not had any users though..just something we wanted to make.

So it is perfect for content locking. Make them fill out a survey then give them access? We can help with that.

Black Label Ads has pre-roll available as well. Please feel free to hit me up directly. My contact info is below. :thumbsup
