Forgot one thing.
After you drag the pick whip to the slider, you have to add another ) at the end of the expression. The final expression should be this:

wiggle(5,effect(“Slider Control”)(“Slider”))

wiggle(10,effect("Slider Control")("Slider"))

I do it another way. Using the Null layer is useful if you’re applying the same wiggle to multiple clips, but if you’re just doing one or two, try this:

Apply the slider control to your clip.

Add the expression “wiggle(5,” to position. (without the quotation marks. Change 5 to what ever number you want. It refers to the number to times a second your video will shake)

Drag the position expression’s pick whip to the slider control. If you don’t know, the pick whip is the spiral below the position coordinates.

Then all you have to do is set your keyframes for the Slider Control and away you go.
