About DMSM files
The .DMSM file is a proprietary VideoWave Movie Project File originally developed by Sonic Solutions and now managed by Roxio. It is used to save timeline sequences, visual effects, and file paths to local media assets. Users typically open and edit these files using Roxio Creator or Roxio VideoWave.
The main disadvantage of the .DMSM format is that it is strictly a project file. It contains zero actual video or audio data. Sharing a .DMSM file with colleagues results in broken links and missing media errors, as the original footage remains isolated on the creator's hard drive. Additionally, the format is completely proprietary. It requires paid software to open and cannot be uploaded to YouTube, played on mobile devices, or viewed in standard players like VLC.
To make the video viewable, users need to convert the project to standard target formats like MP4, AVI, or MOV. However, this file format is notoriously difficult to process outside of its native environment. Standard online converters fail because they look for video data that simply does not exist inside the file. Because it is a closed format, often only the original software can properly read or export the data into a playable video.
Despite this, convert.guru can still identify the file format, inspect the file, and show text or internal content. Just drag and drop your file to see what it is and convert it if supported. By analyzing the raw data, users can often recover the original hard drive paths of missing media, helping them reconstruct lost projects.

The DMSM Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DMSM converter.
