Changing Cell Aspect Ratio
Cameras provide video in 4:3, 16:9 or custom format. Grid cells aspect ratio is changed dynamically per item's aspect
ratio to occupy Scene space.
This feature is used to occupy Scene space efficiently: cell aspect ratio should be equal (or similar) to Camera aspect
ratio.
Additionally, the aspect ratio of cells can be changed manually. To proceed, use Change Cell Aspect Ratio Context
Menu item (invoke Context Menu on any empty space on Scene).
Zoom Windows
DW Spectrum provides a great feature that allows users to create an unlimited number of digital Zoom Windows for a
single Camera. These windows can be placed on Layouts and saved for future use.
IMPORTANT. It is not possible to use Zoom Windows on Locked Layouts.
To configure Zoom Window for Camera:
1. Open Camera.
2. Click on to drag a rectangle on an item. A new item will appear on Scene.
3. Move Zoom Window or resize it by dragging its edges. Zoom Window can be moved between Cameras on Scene.
4. To close Zoom Window, close the corresponding item.
Note: it may be very convenient to use Zoom Windows of fish-eye Cameras. See "De-warping Fish-Eye Cameras"
for more information.
