Studio: Scene View and Matte

The scene view is the center region of Studio, showing you the visual result of rendering and compositing the layers of your presentation, and also allowing you to select and transform elements graphically.

Surrounding the scene view is the matte. The matte may not be visible if your presentation is larger than the available space. (This would be a shame, since it is rather useful; see below.)

Scene View

The content of the scene view depends on whether or not you are using an edit camera. Normally (without an edit camera) the contents of all layer - s seen through the camera for each laye - re composited in the scene view. When an edit camera is used, the contents of a single layer are seen as viewed through the edit camera.

Selecting Elements

In addition to displaying content, the scene view allows you to select and transform visible elements. Click on an element in the scene to select it in the Timeline palette and show its properties in the Inspector palette.

Clicking in empty space will drop the current selection. If you don't have any empty space to click on, you can alternatively click on empty space in the Slide palette to drop the current selection.

Showing and Hiding Bounding Boxes

When an element is selected its bounding box is drawn in the scene view, along with the bounding boxes of immediate children. If this is getting in your way, you can turn off bounding boxes in the bottom half of the View menu (keyboard shortcut: Ctrl-B).

Transforming Elements

When an element is selected, an interactive transform manipulator will be displayed in the scene view. Click and drag on portions of the manipulator to move/rotate/scale the element. (The manipulator displayed is controlled by the current manipulator mode).

Alternatively, you can click and drag on the element itself to affect the transform:

  • In Position mode...
  • left-mouse dragging on the element will adjust the position perpendicular to the camera's view axis. (That's a complicated way of saying that if you drag an item to the left, it will move to the left.)
  • right-mouse dragging up/down on the element will move it farther from/closer to the camera.
  • In Rotation mode...
  • left-mouse dragging on the element will tumble it.
  • right-mouse dragging up/down on the element will rotate it counter clockwise/clockwise within the view.
  • In Scale mode...
  • left-mouse dragging up/down on the element will proportionately scale it smaller/larger.
  • right-mouse dragging up/down on the element will affect the local Z scale.

Matte

Sometimes you need to select an item via the Timeline palette because other items are in front of it. However, when you attempt to transform it by dragging on it (instead of using the manipulators), you end up selecting a different item.

Clicking and dragging in the matte area when an element is selected is the same as clicking and dragging on the element itself. Using the matte for your dragging ensures that you will not accidentally transform the wrong element.
