it wouldn't take that long to just have the lovely lady say the list of shit that you would otherwise have to write out on white cards anyway. Then just cut and export. Probably wouldn't really take all that much longer. Just don't offer to host the video for them or even make them that big. And you can watermark it. Its a good idea. a little more daunting than fansigns. You could just offer it internally via an email instead of a board full of weirdos
