Specify the desired settings and click OK. It is possible either specify the target speed or target video length. See
Initial Video Length and Frames Interval for reference as well.
4. Choose the desired file name, format and location and click Save:
IMPORTANT. If Image Enhancement, Forcing Aspect Ratio, Camera Orientation or De-warping were applied to
the exported source, it will be suggested to the user to keep these settings (may be disabled if needed). Additionally,
it is also possible to render date and time on the video (Timestamps dropdown list). However, these settings will
require transcoding on client, so may take a longer period of time with slightly decreased quality and increased
processor load up to 100% during export.
File and folder operations are performed in the same manner as in Windows Explorer.
The following formats are supported:
 AVI is more widely used, but the codec remains intact (H264). To view exported videos in other players may
require additional codecs. Additionally some codecs are not allowed in AVI format. A warning message will appear.
This is a default format.
 MKV is a more advanced format, but may not be played back on some devices (ex: home media players). It does
not restrict video and audio content.
As soon as export is finished, the video will be available in Local Files in Resource Tree.
IMPORTANT. This resource will be available until Client restarts. To make it available permanently, save the
exported video to DW Spectrum Media Folder (see “Configuring Media Folders”) or create and save a Layout that
would contain this video.
Checking the Validity of Exported Videos
Watermark allows Users to check for validity of footage to determine whether or not any modifications were ever
performed to the native footage. Any videos exported by DW Spectrum (either single Cameras or Multi-Videos) can be
checked for validity.
To check the validity of exported videos:
1. Bring the desired video onto the scene
2. Open Context Menu and select Check File Watermark (or press Alt + C)
