I would like to speedup a video the same way that Enounce MySpeed can increase the speed of video playback without high pitch chipmunk sounds.
I would like to do this to my own .MP4 files that I have recorded.
This video demonstrates the problem and goal
Generally I have 2 goals, shorten the video length by 10-25% and speed up the tempo off my voice without loosing voice quality (pitchiness).
MySpeed works great for playback, but I have tried lots of video editing software (Windows Media Player, Camtasia) and others without ever coming close to the quality of MySpeed.

Yes, Change Tempo in Audacity. If you install the ffmpeg source plugin for Audacity it can read the audio directly from your A/V file. And save it with whatever compression you want. You'll still have to use another program to mux the new audio with the video.
Some players have the ability to do it while playing a video. VLC, for example.

I hear what your both saying about Audacity, but as that is just an Audio program, I have to split the sound of and add it back in.
Technically it is obviously possible to have a program work directly on an .MP4 and speed/slow that file whilst maintaining excellent Audio Pitch quality as the Makers of MySpeed (Enounce) have a product that does just that with a level of quality that I have never seen in any Video Editing software, which is really surprising.
So if technically it is possible to just work directly with the .MP4 then I'm wondering if anyone knows of a video editing tool that can achieve my goal?
I show an example of MySpeed in the video I originally posted.
I have tried Sony Vegas Movie Studio and Searched for Tutorials which I followed and still no Joy with this problem.
I don't understand why a Simple Video Playback system "Enounce MySpeed" can get it so right, but expensive video editing tools Pale in their ability to speed up a video while maintaining audio quality.
I included a video example that I sent to one of the Tutorial Experts.
Maybe this gives a clue and more understanding.

Hope u get this message. It is so easy to do in Vegas your head will spin. All you do is hold down the CTRL key they grab the edge of the video on timeline and drag it longer or shorter. It will slow down or speed as as you like and it will maintain the pitch perfectly.If you want to see what I've done with my videos,
check out my video work on youtube, http://www.youtube.com/user/duhmez/
@duhmez, you're right, but he's a spammer -- don't waste your breath.
