I want to wrap the DV stream from the .dv files into Quicktime MOV (without
transcoding) so they can be imported into Premier Pro. FFMPEG rewraps the
stream but when played in Quicktime, VLC, and Premier Pro there are narrow
black vertical bars on the left and right edges of the frame. It looks like
the production aperture 720x480 is being displayed instead of the clean
aperture 704x480 but that’s just a guess. Can someone tell me an FFMPEG
command that will result in MOV wrapped DV that displays without the vertical
borders?

Thanks for your reply. A dv wrapped .mov file was created but it only
contained the first 17 minutes of the 39 minute source. The resulting file was
viewable and did not have the unwanted vertical bars but, ultimately, the
conversion failed.
