The dmss file format is associated with Roxio Creator VideoWave, a video editing and slideshow tool from Roxio for Microsoft Windows. A project can contain images, background audio, effects, transition information and other slideshow properties.
The file belongs to the VideoWave project workflow and is intended to be reopened in the Roxio Creator software that supports it. It is a proprietary project format, so it is not generally suitable for use as a video file in other media players or editors.
Open a dmss file with Roxio Creator VideoWave or the compatible VideoWave component of Roxio Creator NXT on Microsoft Windows.
Use the software's Open or similar project command and select the file. If the project uses source images or audio stored separately, those files may also be required.
Open the dmss file in Roxio Creator VideoWave and use the software's export or production options to render the slideshow to a supported video format.
This produces a new video file; it does not convert the dmss project into a standard, independently editable media format.
