Exporting Layout in Multi-Video Format
DW Spectrum provides a powerful feature to perform Export in a proprietary format, which has many benefits in
comparison to standard Export (see "Exporting Recorded Region from Camera"):
 It is possible to export several videos simultaneously (for instance, it is possible to export the last hour of
recording from five cameras). The exported files are saved as regular Layout and can be opened in DW Spectrum.
The exported Multi-Video can be navigated through as any other layout (see "Navigating through several cameras
synchronously"), perform Smart Motion Search, etc. It is possible even do Multi-Video Export from Multi-Video.
 It is possible to export additional information (recorded chunks and motion).
 It is possible to prepare a bundled version that can be run and viewed on clean Windows systems.
To do Export in proprietary format:
1. Place the desired Items on Scene. A user cannot export Local Video Files into Multi-Videos.
2. Select the export region on Time Scale:
 Use Right Click Drag
 Open Context Menu on Time Scale and click Mark Selection Start (or press “[”), then Mark Selection End (or
press “]”)
 To clear selection, use the corresponding Context Menu item
 Adjust the export region by dragging edges
 For easier zoom, scroll Mouse Wheel on Time Line.
3. Open Context Menu and choose Export Multi-Video:
If the selection contains empty archive on Camera, it will be exported and NO DATA will be shown when viewing
the exported clip.
Note: if a long period of time is selected for export, it may cause delays. In this case, the following warning
message will appear:
You are about to export a long video. It may require over a gigabyte of HDD space and take several minutes to
complete.
In this case, it is possible to continue working with DW Spectrum while exporting.
4. Choose the desired file name, format and location and click Save (Cancel will close the dialog and no exported
data will be saved):
File and folder operations are performed in the same manner as in Windows Explorer.
The following formats are supported:
 NOV – a proprietary format. Can be opened by DW Spectrum Client only. Can be changed if needed (see "Changing
Multi-Video after Export").
 NOV (Read-Only) – a proprietary format. Should be opened by DW Spectrum. Cannot be changed.
 EXE – an executable bundle (platform dependent – x86 or x64). Can be opened without DW Spectrum installed on
the computer. Can be changed in the future if needed (see "Changing Multi-Video after Export").
 EXE (Read-Only) – a proprietary format (platform dependent – x86 or x64). An executable bundle. Can be opened
without DW Spectrum installed on the computer. Should be opened by DW Spectrum. Cannot be changed.
