Note: The overlay appears as a black line if the clip is not selected and as a white line if
the clip is selected.
To adjust the opacity of a clip (with no keyframes) in the Motion tab:
1 Double-click the sequence clip you want to adjust to open it in the Viewer, then click
the Motion tab.
Note: When compositing clips in a sequence, make sure that you are always working
on sequence clips and not Browser clips. For example, if you do a match frame edit or
inadvertently open a clip from the Browser, you won’t be modifying a clip in the
sequence and so you won’t see changes in the Canvas.
2 Click the disclosure triangle next to the Opacity parameter.
The pointer changes to
the Adjust Line Segment
pointer when it’s directly
over the overlay.
