I ' m not sure this is a smile <| sep |> There will be people who know this better than me , but I ' d do it this way . Read this like an AE TimelineLayer 4 Maybe another 3 D Text duplicate set to multiply or something to apply the text shading again . Maybe this is achieved by the Luma matte of layer 3 alreadyLayer 3 The dupliated 3 D Text for masking invisibleLayer 2 Your Video Track Matte Alpha or Luma I always forget masked to one letter maybe ? Layer 1 The 3 D TextYour video becoming fullscreen should best be achieved by moving the camera so close to the letter that it takes up the whole screen . If the video should move in 3 D space and not just be plain there you obviously need to make it 3 D and parent it to the Text . That would result in a problem if you choose to move the text really close to the camera , though , because your video will be zoomed in , too , then .
