I totally understand what you're saying, but I still disagree, at least for a service where you can upload arbitrary video. Framey is a bit different, because you can reasonably assume an upper limit to the amount of time a user will record themselves on a webcam in a browser (or restrict them to a max # of minutes).

I know you were just using it as an example, but music just isn't a good comparison for this conversation. Video is simply much more expensive than audio in just about every way, from storage to encoding.
