I'm trying to get my anaglyphs (red/cyan) to display correctly/better on Vimeo. As Vimeo doesn't support the anaglyphing (is that a word?) at the player level like youtube, I'm finding the color shift from encoding is causing ghosting in the red channel. Currently I export my stereo Cineform files to Anaglyph H.264 from Premiere, the resulting file is acceptable, both in terms of Anaglyph quality and file size for uploading, then Vimeo has another crack at the file encoding it into whatever format the viewer sees via Vimeo, at each re-encoding stage there is a slight color shift. The left eye (red eye) seems to be the problem.

Anyone got any tips?

In the mean time I'll email Vimeo for player level support.

One thing you might try is using MPEG Streamclip to pull the video down. It would be interesting to compare it on vimeo to playing on your desktop. Not necessarily a help but at least you'll know more.
