Apple Final Cut Pro 7 - Manual (Page 1772)

• Fit within dimensions: Changes the shortest dimension of the exported movie (usually
the height) so that the source sequence or clip fits within the exported movie
dimensions when scaled. For example, if your sequence dimensions are 1280 x 720
(16:9) and the exported movie dimensions are 320 x 240 (4:3), the exported movie
dimensions are changed to 320 x 180 (16:9) and the exported sequence is scaled to
these dimensions. When the “Preserve aspect ratio using” checkbox is not selected,
the sequence or clip video is stretched to fit the export movie size.
