I've seen different sizes across the internet. AdWords has one size that they seem to be pushing: "970x90...This ad format expands to 970x415....This size is ideal to showcase High-Definition content such as videos, photos, animations, and applications."
1) I have my own CDN setup to serve videos. Is that how the video gets served in the ads? Or do you have to upload the videos to AdWords? Or do you have to upload them to YouTube?
2) Is there a maximum length the videos can be?
3) My developer and I could create the ads. But as I'll want a designer to work on it also. So, how would I go about finding a designer who knows what he's doing with these things? Or should I just talk my After Effects guy into doing it? Does anybody know of any one stop shop for these things?
4) The niche is foreign language education. Is there another ad network besides Adwords that would be good for getting these video ads in front of the the right audiences?
Thanks in advance
