    I have a shot of a few seconds duration. I want to trim one side of the image (feathering the edge) so as to make that edge tranparent to the layer below.

    How do I do this?

    [Dave LaRonde] “Double click on the rectangular mask icon AGAIN to make another full-screen rectangular mask in a different color. Do NOT move this one. Go to the switches in the timeline and change this mask’s mode from Add to Intersect. “

    Dave,

    What’s the purpose of the second mask? I was going to suggest the same solution as you except only using one mask set to add (the first one, in your example). I would have thought that would work fine. Why does the second mask help?

    Thanks Dave and Ben, both. I do only need the one mask. Maybe it would help to explain my specific need.

    I have old Hi8 footage with a black edge on one side where picture scanning did not extend. This edge does not concern me so long as it IS on the edge. But I had to steady this drifting footage. But this meant that the footage edge drifted a fair bit left to right.

    Fortunately, the background was static, so I took the first frme of the sequence portion being processed and placed it in the layer below. The effect worked perfectly, except that the black edge of the steadied footage in the top layer intrudes over time into the frame.

    It is just this black edge of the steadied layer that I need to remove.

    I’m a little wobbly about the terminology. Is ‘layer window’ the same as ‘layer panel’?

    Will I need to pre-rendeer my steadied footage before accessing the layer window?
