Blender 2.64 motion tracker and green screen keying need tutorial

Can anyone make a tutorial on this I’ve heard blender 2.64 motion tracking works completly different.


You can try this one. But I’m still a little stuck on getting the floor in blender to align with the floor in the camera picture.


I watched a blender cookie tutorial on tracking which helped a lot but my tracks are still not near where i want them to be. You could start there but it would be great help if someone could create a complete tutorial on tracking.
There seems to be enough differences for a new tutorial to be made so why isn’t there one?
