The camera and projector have shortcut operations neither in the popup menu or represented in video overlays. These are accessed in the Tool window. Most operations in the Compositor window have a tool window which is enabled by activating the toolwindow.png question mark.

In the case of the camera and projector, the tool window shows x, y, and z coordinates. By either tumbling or entering text directly, the camera and projector can be precisely positioned. 9 justification types are also defined for easy access. A popular justification operation is upper left projection after image reduction. This is used when reducing the size of video with aspect ratio adjustment.

The Show tools button works only in conjuction with the other controls on the compositor.

The translation effect allows simultaneous aspect ratio conversion and reduction but is easier to use if the reduced video is put in the upper left of the temporary instead of in the center. The track size is set to the original size of the video and the camera is centered. The output size is set to the reduced size of the video. Without any effects, this produces just the cropped center portion of the video in the output.

The translation effect is dropped onto the video track. The input dimensions of the translation effect are set to the original size and the output dimensions are set to the reduced size. To put the reduced video in the center section that the projector shows would require offsetting out x and out y by a complicated calculation. Instead, we leave out x and out y at 0 and use the projector's tool window.
<p />
Merely by selecting left_justify.png left justify and top_justify.png top justify, the projector displays the reduced image from the top left corner of the temporary in the center of the output.
