Re: filmscanners: Scan for television screen

[Steve Bye]

While it's true that the resolution of NTSC (American standard) is 720x480,
the pixels are not square - they are about 1 high and 0.9 wide. This means
that, though the resolution is 720x480, the aspect ratio of the image is
actually 640x480, or 4:3.

The answer when all the math is done is that, for NTSC, you want to scan to
end up with an image that is 640x480 pixels. Whichever program is used to
convert the image to a signal viewable on an NTSC monitor will take care of
converting 640 square pixels to 720 rectangular pixels. Programs like Adobe
Premier and Apple's Final Cut Pro do this automatically.
