Re: filmscanners: Scan for television screen

Thank you and a follow-up:

Scan 640 by 480 at what resolution?  96spi as for the web?  More or less
than that?  The 640, then, would stretch across the screen or would it fill
only a part of the screen?

My son said they can scroll the screen so the 480 height should work out
fine one way or another.

| It may depend on how you display the image on an NTSC monitor.  For
| example, if I send my 2nd video out to my TV, it somehow compensates for
the
| TV having fewer lines vertical, and what should be square is actually
| square.  On the other hand, if pixels were converted to lines, then the TV
| would be missing top and bottom lines.  I remember the Amiga which was
| designed for NTSC having a pixel resolution of 640 by 400, but since a
| normal TV's aspect ratio is 4:3 like a computer monitor, I believe you
| should scan 640 by 480 ... if this provides too many vertical lines for a
| TV, then change its image size to 640 by 400 with the "keep aspect ratio"
| turned off ... this should make squares true on a TV ... hopefully.
