Colour Key Problems

[Jen351916451msr]

Hi there,

Does anyone know why i can't access the colour key?  I have found it in the effects menu, but I can't use it to edit my video.  I drag it onto the clip but it doesn't do anything.

You are looking at the source monitor. Program monitor is the one you should be using.

Reset workspace to get the monitor.

Then try pressing Enter to render the timeline and turn the red line above the timeline to green.
