Nx Witness offers many possibilities when working with Multi-Videos. A user can do almost everything as with regular Layout:
•Add or remove items. For instance, if Multi-Video was exported from 10PM to 11PM and a new camera was added, it would get synchronized with other cameras and be displaying in the same archive (10PM – 11PM). See "Adding Items to a Layout" and "Removing Items from a Layout".
Note: Local Files are not allowed in Multi-Videos.
•Adjust layout appearance (move, swap, resize, rotate). See "Arranging Item Display in Layout".
•Save modified Multi-Video. One restriction is applied: it is not possible to mix Local Videos and Cameras in a single Multi-Video. Same as Layouts (see "Saving Layouts"), but can be performed by Viewers.
Note: Multi-Video can be saved with a read-only flag (modifications will not be saved).
