# Layout Management

Navigation: Working with Nx Witness > # Layout Management |

Layouts are a powerful and flexible way to view video data in Nx Witness. A Layout can contain up to 24 items for x86 architecture or 64 items for x64 architecture – including c amera streams, local video files, web pages, or images, which are not restricted in terms of location, size, or orientation.

Initially, a layout is created and configured by an Owner or Administrator. It can then be assigned to Viewers. Viewers can also create their own layouts based on the resources (devices, local files) available to them.

If running on a multi-machine System, c hanges to shared layouts are activated immediately on all machines. Refer to “Opening and Closing Saved Layouts” for more information.

The following layout controls are described in this section:

•Tabs for Layout

•Creating and Assigning New Layouts

•Adding a Background to Layout

•Saving Layouts

•Opening and Closing Saved Layouts

•Locking Layouts

•Deleting Layouts
