To have the video not move and have the Text layer move in 3D space place the Text and Video in two different groups. Make the Video group a 2D group. Make the Text group a 3D group. Then you can animate the text with the camera and the video will not move.
Or you can have both the text and the video in a group and just change the Text layers Rotation independently of the video.
Is this what you are looking for?
