First, enable the shift option by checking the check box below the Distance Back: setting. Refer to Figure 20-14. Then, select either Shift left or Shift right from the drop-down list. Finally, enter a distance in the text box next to the drop-down list. The camera will be shifted left or right for the distance specifi ed in this text box, resulting in the view shifting in the opposite direction. This shifting option is available for both “crane” motion types. When Crane up is selected, the camera drop-down list is automatically set to Starting point. This means the preview image shows the beginning of the shot before the move- ment is applied. If the Always look at camera pivot point check box is not checked, and depending on the movement settings, the model may move off the screen in the shot. Crane Down When Crane down is selected in the Movement type: drop-down list, the camera will move from top to bottom and then forward. This results in the view moving from bottom to top and zooming in. This movement type has the Duration: text box and the Always look at camera pivot point check box described previously. The Always look at camera pivot point check box is checked by default. This movement type also has the left/right shifting option described in the previous section. Instead of Distance Up: and Distance Back: settings, this movement type has Distance Down: and Distance Forward: settings. The value in the Distance Down: text box is the distance the camera cranes down in the shot. The value in the Distance Forward: text box is the distance the camera is moved forward in the shot. When Crane down is selected, the camera drop-down list is automatically set to Ending point. This means the preview image shows the end of the shot after the move- ment is applied. If the Always look at camera pivot point check box is not checked, and depending on the movement settings, the model may start off the screen in the shot. NOTE NOTE All distance values related to the Crane up and Crane down movement types repre- sent how far away from the view the camera must begin before the cinematic shot is started. For example, a large Distance Back: value means that the camera may have to begin at a point beyond or even around the view in order to travel the distance back to display the current view (when Ending point is selected in the camera drop-down list). It is always good practice to make a single change to the movements, and then preview the shot. This is especially true for the Crane up and Crane down movement types. Look When Look is selected in the Movement type: drop-down list, the camera pans based on the values for left/right and up/down to display the view, Figure 20-15. For example, if the movement is set to look up 45° and Ending point is selected in the camera drop-down list, then the camera begins at a 45° angle below the view and looks up to display it.
