I think Google is a better option. Tell me which facebook user really needs your product while using Facebook? I mean there is maybe a VERY small of group (too small) who are interested in video templates and who would actually click on the ad.
First I think, you don’t need any ads. Sometimes VH is just luck. The people who are actually ready to buy something, are already here. The question is, if the ad clicks increases your sales or just traffic.
If you really want ads, I would prefer Google.
