iMovie09 How to change the speed of a clip to achieve an accelerating effect

[Snookerman]

I have a clip of a background moving to the right that will be projected in the background of a play in order to give the feel of motion in a train. I want the clip to start off with a still shot and then accelerate as if the train first is still and then accelerates until reaching full speed (which is the normal speed of the clip).

I know how to change the speed of a clip by going to "Clip adjustments", but I don't want to change the pace of the whole clip, I want the speed to increase gradually. I tried to mark short parts of the clip and then change their speed to increase gradually, but that is too rough. Isn't there any "acceleration effect" built-in? I appreciate quick answers Thanks!

Perhaps you could split the clip in the timeline into smaller clips and the increase gradually.

As I said, that was too rough, I want a smooth acceleration.
