Windows Media Video is a popular video format used in Windows. If you are looking for a tool to edit the attributes of .WMV files, then Windows Media Stereo Attribute Editor is a nice pick. This freeware tool is a handy utility designed to enable you to add metadata to a stereoscopic Windows Media video file. Simply select the file and you can edit the attributes from a simple interface.
The portable application has three tabs- Stereo, General and Movie Disk. You can set the Stereo parameters in the first tab. The general tab allows you to set the author and copyright information of the file.
Embedding metadata into a file avoids that the Stereoscopic Player asks for the stereoscopic format when the user opens the file.
