I use Sony Vegas Pro and it has a playback option called Velocity Envelope. This tool allows me go anywhere from -100% to +300% of the normal speed of the clip. It also lets me change speed instantly or over a desired period of time. For example, playing back at 25% speed and then, over a period of 1 second, ramp it up to 100%. This is easily accomplished with the Velocity Envelope tool.
