letterbox mode.

downconverting HD video to SD, the video will be exported as anamorphic
(horizontally compressed 4:3) video.
Select Recompress if you're exporting using the same compression format,
9
frame size, and frame rate as the source material in your sequence, but using
a different data rate, scanning mode (interlaced or progressive), or bit depth
(8-bit or 10- bit). For example, you'll need to select Recompress if your
sequence is NTSC MPEG-2 I-frame at 50 Mb/sec and you want to export to
an NTSC MPEG-2 I-frame 20 Mb/sec file.
¦ Note In most cases, it's recommended that you do not select Recompress .
This retains the quality of your video. It also optimizes the speed of the export
because realtime video segments that have no effects will be copied directly
to disk without recompression, assuming that the compression and video
format of your video clips matches the format to which you're exporting.
Click the Matrox Export tab.
