DV Movie Export Component

The DV movie export component converts a file containing a QuickTime movie to a file containing DV data for the movie.

The input file must contain a video track; the DV movie export component cannot convert a movie that contains only audio.

If the video track in the QuickTime movie is already in DV format, the DV movie export component does not recompress the video. This makes it possible to edit DV video in QuickTime and then export it without any loss of video quality due to recompression.
