To manually control the fixtures, first select the video panel, and go to the 'Parameters' section in the side bar. Here you can control the DMX channels of the fixture.
So for the video panel, we set the fader to 100%, so it is on, and apply a video to it,
as is explained in the Media Feeds section.
Then select both of the Martin MAC Encore Performance WRM fixtures, so you can set then parameters of both of them at the same time, and set the shutter channel to 20, to open the shutter, an the fader to max (100%), and zoom to 50%.
Your scene should now look something like this:
(We changed the environment settings a bit, lowering the ambient and the background color to make the fixtures more visible.)
We can now try to focus the 2 fixtures at the feet of the girl, by using the 'Focus' operation 
, by clicking and dragging the mouse in the scene. (As you can see, in this case the fixtures can not fully reach the desired focus location due to the fact that they reached the limit of the tilt movement of the fixture.)
