NTSC test pattern generator on VCD? - test-drb@ccmp.vtda.org

  Now I wouldn't mind a real colorbar generator, but
a
algorithmically-generated MPEG would be adequate for non-broadcast
use, surely.

Does anyone know of the existence of such a thing?  Theoretically, one
could perhaps generate a "proper" still image from a program like
GIMP/Paint/Photoshop, etc... then use a movie tool to generate
'frames' from it, then make an MPEG to play the image as long as one
would like (a VCD or SVCD is around 45 min on a CD-R blank) -
presto... el-cheapo color bars. 
I know there are DVD test discs out there that have test patterns on them.

This would actually be fairly trivial for me to whip up on my computer. I 
just did a quick google search and the first hit had a downloadable GIF 
of the standard color bar pattern. I could toss a 1 MHz tone (IIRC that 
is the right freq, I'll have to look it up to be sure) in the background, 
and loop it in Quicktime, then output to VCD.

If you really want one, let me know, I can build you a VCD this weekend 
and mail you a copy.
