Actually, SVHS is terrible in either standard, it's not just the poor colour reproduction accuracy in NTSC, in either format SVHS (and to a much greater degree VHS) suffer from very low spatial resolution and very low signal to noise of the colour information in a picture (chrominance). SVHS video has been likened to carefully drawing a picture in black biro (luminance) and then colouring it in with crayon (chrominance), while wearing boxing gloves. VHS replaces the biro with a magic marker, and the crayons with 4-inch house-painting brushes. > > Modern broadcast video cameras have a horizontal resolution of > > about 850 lines. > > And VHS is still limited to 200...

At last I can distribute videos to clients on a medium that won't throw away 75% of my efforts -- C. -- Craig Harding crh@outpost.co.nz "I don't know about God, I Outpost Digital Media Ltd crh@inspire.net.nz just think we're handmade" http://www.outpost.co.nz ICQ# 26701833 - Polly To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
