How to add speed to the animation?

[rfribiapina]

I generated a sprite image based on an animation made in After Effects, which lasts 2 seconds, based on 30 fps.

mtAnimacao = new Motio ($ ('.animation') [0], {fps: 30, frames: 75});

I need to increase the speed of this animation dynamically, so try to leave the fps option with 120, but the animation was not faster.

How do I get this speed increase?
