On the hand/brush clip the early footage has a light background because the camera is trying to show the dark velvet background. Pretty soon after I move the brush into the camera's view, certainly by the time my hand enters, the background darkens to almost black, which is what I want.
I cut, or split the clip to separate the light background from the dark, then made a mask and created a lower layer of black to darken the background on the light section.
So far, so good.
Then I wanted to reduce the size of the hand/brush through the entire video. I cannot figure out a way to link the clips so they are both reduced in size by the same amount. I've only been able to figure out how to reduce them one at the time, and am not certain they've been reduced equally.
Is there a way to lock clips together once they have been cut?
thanks,
Paz
(I have been able to unlink and re-link audio and video, but not two or more video clips.)
