How to make a slow motion Jump back movie in QuickTime Pro

I've just worked out how to do this, makes upgrading to Quicktime Pro worthwhile.

1. Take your Quicktime Jump back movie and open in Quicktime Pro (£20 upgrade from regular Quicktime). We'll call the screen that opens Screen X
2. Click window then Show movie properties from the drop down menu
3. Click soundtrack and then click delete
4. Click the Video track and click extract (this will open the video again in a new screen which we will call screen Y)
5. Click edit, select all, copy. then click on the movie screen and click paste.
6. Drag the right half triangle on the time bar at the bottom to the end so that the whole time bar is highlighted.
7. Go to the original movie screen X and click edit, select all, copy and then you can close this screen X as you wont need it anymore, no need to save changes.
8. Go to back to the other screen Y, click edit then click Add to selection and scale.
9. This Screen (Y) should now play a slow mo version of your original jump back movie.
10. Save as Jump back Slow mo

Love this, just done a slow-mo version of my rolling GARBHA PINDASANA, funny.

PS. Anyone recommend anywhere to practice in Manchester UK?
