Speed up movie clip

Hello,

Is there a way I can speed up one particular movie clip in my project? I’ve tried changing the frame rate, but obviously this changes the frame rate for the whole project which isn’t what I want.

The current project frame rate is 20fps, and I need this one movie clip to be running faster at say 30fps.

Is there a way I can perhaps achieve this using Actionscript 2.0?

Thanks,
Cined.
