Sealed MPG movie
File type: Digital video and movie file
Files with the smpg file extension are sealed, rights-managed movie files used by Sealed software.
They contain protected MPEG video and may require authorization before playback.
File type category:
Digital video and movie file
Date updated: November 4, 2026
The smpg file format is associated with Sealed, digital rights management software from SealedMedia. SealedMedia technology is now known as Oracle Information Rights Management 11g.
An smpg file contains protected MPEG-1 or MPEG-4 video. The associated MIME types are video/vnd.sealed.mpeg1 and video/vnd.sealed.mpeg4. The protection is intended to control access to the movie rather than provide a general-purpose video container.
Open an smpg file with compatible Sealed software or an Oracle Information Rights Management client. The file may also require permission or credentials from the organization or distributor that supplied it.
If the required software is unavailable, contact the file provider for an authorized viewer or access instructions. Renaming the file or opening it in a regular media player will not remove its protection.
An smpg file cannot normally be converted with a standard video converter because it is a protected SealedMedia movie file.
If you have the necessary rights, contact the file provider about an authorized conversion or an alternative copy in another video format.
