Importing Older DVD Studio Pro Subtitles
Because of the way they are created, you cannot directly import subtitle files created with
the Subtitle Editor in earlier versions of DVD Studio Pro. These subtitle files have an “.SPU”
extension.
However, you can import older DVD Studio Pro projects that contain subtitles into
DVD Studio Pro 4. Each subtitle entry is converted to a TIFF file and placed on the timeline
at the correct location. Because the subtitles are TIFF files, you cannot edit their text within
DVD Studio Pro 4.
