LookOut | Zoom
Video Information
In these videos, the user is given control over star camera focal length changes. Due to limitations of our current star camera, the zoom range is discretized to three levels (1x, 1.5x, and 2x). In the illustrated footage, the star camera frame is
outlined with a blue rectangle.
For Consistent Zoom and Area Based Zoom, user defined required points are modified to keep star camera framing consistent even when zoom changes. For Consistent Zoom, the user has
requested that the actress remain on the 1st and 2nd thirds both vertically and horizontically respectively. In Area Based Zoom, LookOut changes zoom based on the size of the actress on screen. The script info panel shows the modified required point that keeps star camera framing consistent under zoom.
For the other two other videos, the behavior is different; LookOut has been instructed to keep the actor required point unchanged regardless of zoom.
For Area Based Zoom, the zoom level is determined automatically based on the size of actors in screen space; for the other videos, the user has chosen zoom levels for each behavior in mini-scripts that they can then fire using voice commands.
