600D - Start Rack Focus with "Q" doesn't work while recording
The problem is, i've an actor and a background. I set the start and endpoint. Without recording the "Q" button works fine and i can exactly start the rack focus when needed. But if i press the record button and go to rack focus, the focus beginn to work after 2 sec. If i press "Q" at the time i needed, nothing happens. If i press "set", the focus comes after two sec. when i press"play" the focus comes also after 2 sec. But i need the rack focus by pressing "Q" while recording. Is this possible ?
