Hello,

I have got a question that I hope one of you could answer,

I have a .mp4 movie which speed I would need to control by pressing a certain button, this speed would have to increase and decrease based on how quick you are tapping this certain button, but it would need to be smooth (it is real life footage), is this possible?

If so could any of you point me in the right direction?

Thanks in advance.

Also I use CS5.5, if that helps.
