I've read this, but Pirazzi is referring to uncompressed SD codec for 13.5-MHz sampling rate standard.
Per Final Cut Pro 7 User Manual: "Most SD video devices actually use 704 or 708 pixels for picture information but stretch these pixels to 720 when recording to tape. ..."
I think born digital DV may be different from 13.5-MHz sampling rate.
How do you set the source movie to Encoded pixel mode from Compressor 4?
There is no similar option like in QT7.
Does it do this automatically from Compressor settings "Add clean aperture information"?

It depends on YOUR source and YOUR device.
See exact (preferred) settings for your final display target.
My DV-NTSC encoder uses 720x480 for digitized area, 704x480 for display area, and 4:3 for final display aspect ratio.

Under QuickTime, PixelAspectRatio is calculated from clean aperture rectangle.

Yes, uncompressed SD is 10:11.
But when I look at a .dv file with DV Analyzer, I see:
PixelAspectRatio: 0.889
And when I look at a Quicktime file with DV with DV Analyzer, I see:
PixelAspectRatio: 0.909
PixelAspectRatio_Original: 0.889

8:9 is incorrect. It should be 10:11 for SD video.
search wikipedia with /Pixel_aspect_ratio.

I thought the pixel aspect ratio of DV-NTSC is 8:9, not 10:11. Am I wrong?
