Shaking a Clip
This wmv
file is an example of how to make a clip shake / vibrate like a poorly mounted
camera was used. It was supplied by cwrig. It is posted in response to a
question on the Adobe Premiere forum.

The question was:
I have a still JPEG image of the cockpit-interior/dash of a car. I am trying
to create a realistic and intense vibration/shaking effect like that of a poorly
mounted interior camera. The still is only going to be used for maybe half a
second.
I have tried to use the motion settings in a variety of different ways but it
always seems to accelerate or decelerate
the clip causing a smooth undulation instead of causing a shake effect.
I need an absolutely unsmoothed, linear, movement from point to point. Anyone
have any advice ??
The answer from cwrig was:
I just gave it a try and came up with this method:
1. Drop your still image on to the timeline set to 8 frame resolution (or
similar)
2. Apply 120 zoom to the whole clip (beginning
and end)
3. Cut the image with a razor into 12 or so individual clips about 4 frames
long
4. Now; go into each clip and go back into motion settings. The zoom should
already be set, now set the X, Y coordinates slightly different on each clip. In
my example, I set Y to 4 at the beginning,
-1 at the end; then on the next clip I set Y at 2 at the beginning
and -3 at the end. Make each clip a little different to give it the natural
random shake appearance.
Don't over do the X, as you mostly want up and down movement. But throw
in a little subtle X movement also.
5. Now set camera blur filter to taste on each clip. This gives a little blur
as you would get in real life.
6. Now; the twelve 4 frame clips won't give you much time; so what I did is
render that much to an AVI; then just drop the same AVI 5-6 times to get the
length you need. I ran a couple in reverse for some more randomness.
