Another possible way is to create a Null layer, and make it the parent of your camera. Offset the position of the camera from the centre of the null, and then rotate the null.

If you have illustrator, you could check out this tutorial:

Also, since you mentioned Photoshop, if all else fails, it is possible to output an image series from AE, run it through a batch process in Photoshop and then import it back into AE.

This tutorial uses batch processing to resize a series of photos, but it could also be used to apply any photoshop filter:

Of course, it’s a lot nicer if there’s a way to do the filter in AE itself, but I can’t think of an AE filter that does the equivalent of that.

Whoops. I forgot step 1.5, learn how to keyframe the position of masks.

Now, whether you want to do a four point track like DeaditteX said or something simpler depends on how unobtrusive you want this to be. If you’re willing to have people notice, “Oh, they blurred out that license plate!” you can do it much simpler by just keyframing the position value of the adjustment layer, then you need to only track one point instead of four.

Things you might want to play around with are:
Burn Film
Roughen Edges
Fractal Noise

Or maybe shoot some hand-held random crap. Run some filters on it, up the contrast, maybe invert it, add a solid white layer on top of it, masked with heavily feathered edges, so we only really see the outside edge. Then add an adjustment layer and up the contrast then blur. Take that composition and layer it on top in darken mode.

[Ryan Hill]

The steps are:
1) Learn about masks
2) Learn about adjustment layers
3) Learn about the blur filter
4) Create an adjustment layer with a blur filter applied, then mask out the license plate

There is an “Audio Waveform” filter. If you import the sound of a sine wave, you might get what you’re looking for.

Also, you could take a dot, apply a sin expression to its vertical position. Then use particle playground to get it to emit particles that float to the left, maybe? Or echo is another approach.

Or, you could create a whole image of the wave form in photoshop, import it, apply a track matte that keeps the right half hidden while you move the layer to the left. Then duplicate the layer and show only a thin vertical stripe of it and apply glow, so you have the glowing dot.

Or, you could apply a sin expression to something’s vertical position and a constant horizontal motion; convert the expression to keyframes, then copy the keyframes into a mask and apply stroke to the mask, then use that as above instead of a photoshop image.

Of course, it’s quite likely they also had white contact lenses in Xmen. Back in the old days, they would do a similar effect with the skin of a boiled egg.

If you really want a computer solution, and the shape isn’t matching up, you’ve got a lot of rotoscoping to do.

In what way do you want to animate it?

[Ryan Hill]

What you want to look for is how to keyframe the position and scale.

Step 1. Get a picture of a sine wav.
Step 2. Animate its position value.

Could you explain your question better as to what you are having difficulty with?
