the fb video is a low resolution one
Yeah, low res video, by a single unmoving camera up in the stands at the net. I imagine a fan cam. I don't know who would pay for a dozen HD cameras and the people to operate them. And even though it rubs my sense of entitlement the wrong way, I understand that, after all, it is just a group of teenage girls playing volleyball on the other side of the planet (from me). I would have been happy with watching replays, in the name of research, uploaded after the fact, but I doubt these games are even being broadcast anywhere to be uploaded later. I dunno.
It may be easier for fans of other nations whose players have more diverse body types and hairstyles, but with the Japanese I can't even tell who is who outside of Kurogo (because she wears pants, is tall, and I recognize her jumping style).
I think someone mentioned at least the finals may be broadcast/streamed for us to enjoy. That would be cool, especially if Japan is in them I think they will be.
