[Bf-funboard] VSE code

[Knapp]

Don't forget that with blender but not the VSE but the compositor you have
a LOT of very powerful tools to manipulate the video plus tracking can be
done in another section and the Green screen tools are there. On top off
all that you can use video as textures on the 3d side with animation
together.
