[OT but not too much] What video streaming solution for HIGH quality ?

Julien Bayle's icon

Hi there,
I'm trying to release some video including visuals with an high density of thin objects (lines/mesh)
I pushed it to youtube from screenflow and it destroys completely the texture by adding a lot of artifacts.

https://www.youtube.com/watch?v=QOvQcb-iiBg is the video, but the artwork (which is just a screen capture) reveals a lot of details .. of course.

JWplayer + flv can help but it isn't really a streaming and probably require huge bandwidth server.
currently trying on vimeo.

any opinions/experiences ?
