DW Spectrum 3.0
Rev. 072017 Page | 167
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:
Note: 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. These settings are not applied for the EXE format.
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.
 MP4 is another advanced format as well, but may not be played back on some devices (ex: home media players). It
does not restrict video and audio content.
 EXE is used for distributing videos to the users who do not have any codecs or media players installed. As soon as
this executable is started, new Client instance is run and plays back the exported video. In this case, the data on
motion and recorded fragments is also exported.
Note Following warning will appear if the file is larger than 4GB.
IMPORTANT. Files produced with the x64 version of software will only be viewable on Windows x64; however, x86
can be viewed on any architecture.
As soon as export is finished, the video will be available in Local Files in Resource Tree.
Note: 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.
Also, see the "Viewing Videos Exported from a Single Camera" section for more information.
