you can create a function like this:

```auto
fps = function() {
	this.nextFrame();
}

```

to speed up your movie you’d set an interval

```auto
fpsinterval = setInterval(fps, milliseconds);

```

and to restore the normal fps you just need to clear the interval

```auto
clearInterval(fpsinterval);

```

just use the milliseconds you want to the function to wait between every execution and that’s it 🙂

by the way … there are a few threads about this. i’d recommend a search 😉

it’s not that hard 😉

in the first frame of the movie or a movie clip paste the function

let’s say that you want the first 120 frames to go at 48 frames per second. that would be something like 20 milliseconds … a little more i think.

in the first frame you’d have the interval

```auto
fpsinterval = setInterval(fps, 20);

```

then at frame 120 you clear the interval

```auto
clearInterval(fpsinterval);

```
