Head Turning Effect Slow Down and Saving [How To]

[rightonrva]

I would like to create a head turn effect by adjusting the horizontal slider as seen in this youtube tutorial video.

The effect works great when I move the slider manually, but I can't figure out how to move the slider very slowly so that it fills up a 15-20 second video clip from the parameters of horizontal displacement of -7 to 6. I'm a noob, so this is new to me. Thank you for your help.
