[Dan Edwardson] “I want to have some shots come up at the top and move along, kinda like a moving Picture in Picture”
Just put each of these shots each in its own track above the “green” in the timeline. Select the first of these in the timeline and position the CTI over the first frame of that shot…(page up or page down).
In the Effects Controls palette click on the word “Motion”. Twiddle open Motion to expose the parameters of Scale and Position. Click the small “Toggle animation” buttons for scale and position.
You will see a white bounding box around that clip in the Program Window. Moving and scaling is just like Photoshop…set the position and scale for the beginning of that shot. Page Down and then Arrow back to position the CTI at the last frame of that shot. Reposition your shot for the last frame.
