With multi-video export it is possible to export video and audio from the archives of several cameras simultaneously (for instance, the last hour of recording from five different cameras). You can also export multiple local video files. However, it is not possible to mix both local videos files and cameras in a Multi-Video export.

The exported files are saved either in a proprietary format that can be played by Nx Witness, or as an executable bundle that can be viewed on any Windows computer. The proprietary format has many benefits in comparison to standard single camera export. The exported multi-video layout can be navigated, manipulated, and searched like any other layout (see "Navigating through several cameras synchronously" and "Smart Motion Search"). It is even possible to perform Multi-Video Export on a multi-video export.

IMPORTANT: An exported video will only be available until the client restarts. To make it available permanently, save the exported video to the Nx Witness Media Folder (see “Configuring Media Folders”).

To export multiple videos into one file

1.Select the desired item in layout and region in Timeline and open the Export dialog "see Exporting for details".

2.Click on the Multi Video tab and enter these required parameters: Folder, name and file format.

3. Optionally, you can check Make read-only to prevent the exported video from being edited.

4. Click Export.

If the selection contains empty archive on a given camera, it will be exported and no data will be shown when viewing the exported clip.
