Looking to create filming in the wing mirror effects - vibrations

I really like the look when during car chases they show the pursuing car in the wing-mirrors and the image is vibrating very quickly. Can this be accomplish in AE?

Never thought about making this effect - I figuerd it's always been done live.. but yeah - I think it's possible...
get footage of the mirror..
you're gonna wanna motion track it. then get your "reflection" footage and size/crop until it fits in the mirror (apply a mask the shape of the mirror on the "reflection" footage).
Color correct it...
turn on motion blur for it and comp and the original "mirror"
once it looks good - there's some sort of "turbulent displace" effect I've seen in there.. never used it but I hear it makes it look like its vibrating. apply that to the "reflection" footage and it *SHOULD* be exactly what you're after....
Hope this helps - if you pull it off let me know I wanna see :)

I don't think Turbulent Displace is what you want, that distorts the image, doesn't shake it.
I'd add a Black solid above the layer with the shaking in the mirror footage. Mask the solid in the shape of the mirror. Then wiggle the position on that footage (not the solid). Something like this:
wiggle (20, 10)
Copy the expression, Altclcik the Position Stopwatch, Paste.
Now the footage chatters in the masked are.
Select the solid and footage and Layer>Precompost (Move all Attributes, open comp). Now you cna change how often it shakes, the 20 (Frequency) and how much it shakes, the magnitude, the 10. If you want highlight the 20 or 10 and pickwhip to a slider you put on the footage, then you can keyframe the changes in frequency and magnitude. Ask if you need a walk through.
Now take that precomp back in the main comp and add the tracking data, or parent it to a Null that has the tracking data applied, easier to tweak any flaws in the tracking data that way.
