Supported file formats
For a list of file formats that Microsoft Expression Media supports, see the Catalog Importers dialog box.
You can also import camera raw file formats if you install the appropriate codec, which you can obtain from the camera manufacturer's website.
To open the Catalog Importers dialog box
On the File menu, click Catalog Importers.
The Media list contains the media file categories that Expression Media supports. The columns on the right display the kind and type of file, according to the file category. To remove a Media listing from the Kind/Type columns, click the corresponding box to clear it. Note that removing a media category also prevents Expression Media from importing it.
