How to use a driver to pan and zoom an image I am trying to follow this answer: Pan or zoom in the VSE (accepted answer)
After I right click on x offset and select Add driver, the x offset turns purple. I am not sure how to see the graph screen or how to add keyframes as suggested in the answer.
How does one see the graph screen, and add keyframes (So I can animate the x-offset of a photo to get  a pan and zoom effect)? Could someone please provide some more detail?
Either you should be using a driver OR you should be using keyframes - not both since one will override the other. It sounds like you should actually be using keyframes - so right-click and Remove Driver.
Using keyframes the field should be yellow/orange/green to indicate the keyframe. Move to your frame, set the value, then hit ‘i’ to insert keyframe. No need for driver.
