James,
The way I made this happen was similar to that, but rather than copy and paste, I created a Pan Preset.
I wanted a consistent Pan, same speed and distance. However, where the move took place on the timeline was not as precisely critical, within +- a second or so was accurate enough for starting location.
The way I made this work, since I had about 200 of these moves to make, was to create a Preset Pan/Crop, named it “Move Left”.
I would place the cursor on the timeline approximately where I wanted the move to occur. Then I would zoom in so that each Grid Mark was 1 second in length. I would scrub to the nearest Grid Mark and create a Key. Then I could easily scrub to the next Grid Mark, exactly 1 second further along the timeline and use the Pan Preset “Move Left”. This made my Pans exactly 1 second in length, nice and easy, without fumbling around on the timeline.
When I needed to move the talent back to the center I reversed the process. The trick was zomming in so that the Grid Marks were 1 second in length, that made for very simple timing control.
I put a “Move Left by Grid” and “Move Right by Grid” on my ShuttlePro, so it worked in just a few key strokes.
Simply get close on the timeline, zoom in until 1 second Grid Marks appear, click ShuttlePro to move the cursor to the next Grid Mark, create Key, click to the next Grid Mark (exactly 1 second apart), click “Move Left” preset, voila, 1 second Pans all the same time and distance.
I got pretty fast after about 10 or so of these moves.
