Vimeo quality is low

Hello,

The EasyFancybox plugin automaticly detects my vimeo links, which is great!

But the quality of the video howerver is pretty low.
The original video in Vimeo is of a nice/high quality, but when viewing the video in the Fancybox ‘overlay’ there isn’t much left anymore.
We are using very graphical videos, so I understand that’s a bigger problem than ‘real-life footage’.

But is there a way to get a higher quality video in Fancybox?

This is the website; http://graficonnect.com/

Kind regards,
Matthijs
