You can limit the files displayed in the open dialog to quickly access particular file types. In the dialog window, simply choose a file type to display in the Files of type area. For example, if I only wanted to view all the Vegas Project Files (.veg) I can choose that from the list of file types and only view those files.
In the Vegas Pro Project Properties window, you can automatically match the settings of any media file. To do this, simply click the Match Media Settings button in the Project Properties Window. You must then choose which file you’d like to match and click Open. Your Project Properties should now match the properties from the selected media file.
