Change embedded video framerate

I have several embedded video clips, they are all at 36fps and look good. however, there is one section that I’d like to play faster.

How would i set actionscript or something to play just that part faster?

I am trying set interval stuff, but its not working right. Maybe there is a way to turn it into a movie clip and then apply script to that?

i just cant figure it out.

thanks for any help!
