But I do want to say: the cost/benefit analysis needs to consider the quality of the viewers and not just the quantity. 

Even if we only consider the quantity, I wonder how the cost of  making the videos compares to the cost of bringing people here. For someone living in a remote part of the globe, the cost of participation at Wikimania is something like $1500-$2000 (plus whatever costs it incurs on the organizers). Multiply that by a few hundred and the number you get is way higher than the video production costs.
