I've recently created a little widget that opens an image adjustments menu on top
of the playing video (thank you Muli Dayan for your help with this one!).
The widget allows video image manipulations using these CSS3 filters:
Chrome and Safari except CSS filers by defining the "webkitFilter" property.
FireFox requires definition of the "filter" property.
IE is not supported as it lacks support for CSS3 filters.
