  In your composition settings, “Advanced” tab.

  No. Motion blur is a composition property (as your composition represents the virtual camera). If you need to change settings individually, pre-compose. For the rest, read up on Wikipedia or the manula or wherever. It doesn’t hurt to know a little about shutter phases angles and exposure times and how they affect your stuff.

  ok so would it be perhaps better to manually do the effect with radial blur to zoom? for more control ?

  Depends on what you are trying to do. The quick way round would be to use CC Force Motion Blur on an adjustment layer on top of your other layer (assuming you have AE Professional), but of course Radial Blur would give a much more controllable and stronger result. It’s just not physically correct, so to speak.

  But like Mylenium said, you can just precompose the layer you want to have a different Motion Blur setting. Under the comp/advanced settings you are changing the virtual shutter angle from the default 180 degrees to something higher for more blur.

  AE’s MB, like Mylenium said is a virtual camera. And just like a motion film camera, the gate is spinning while the film is being pulled through. By default a film cameras gate is open half the time and closed half the time so that means that 180 degrees of the gate “Pie” is exposing light. Just like in a real camera you can change the shutter angle to be smaller for more choppy motion (less than 180) or more for smeary motion. For example a lot of music videos are shot with the shutter angle set to 45 degrees so it feels choppier and more “intense”.
