A file with the dmsm file extension is a Roxio Creator VideoWave movie project file.
It stores a movie project's editing information rather than a finished video.
File type category:
Digital video and movie file
Date updated: October 6, 2026
The dmsm file is used by VideoWave, the video-editing component of Roxio Creator NXT from Roxio. Roxio Creator NXT runs on Microsoft Windows.
The file contains movie project settings and other editing data, including effects, transitions, and references to the video and audio files used in the project. The referenced media files may also be needed to reopen the project correctly.
After opening the project, Roxio Creator NXT can export the finished movie to supported video formats. The resulting movie can also be used with Roxio's disc-authoring tools to create DVDs or Blu-ray discs.
Open a dmsm file with Roxio Creator NXT on Microsoft Windows. Use VideoWave within the application to open the movie project.
If the project refers to source video or audio files, keep those files available in their original locations or relink them when prompted.
Open the dmsm file in VideoWave within Roxio Creator NXT, then use the application's export or output options to render the project in a supported video format.
The project file itself is not a finished video and cannot be meaningfully converted without its referenced media. The completed movie can also be sent to Roxio's disc-authoring tools for DVD or Blu-ray creation.
