John,
It's not that easy to discuss the IV24 well, since it's true impact
(pardon the pun) is visual. The board does have this strange habit of
having a few pixels that sparkel for the first 10 minutes that the machine
is powered up. I'm not sure if it is a problem configuring some of the
boards software controlled fine tuning controls or a matter of the board
warming up a bit and coming up to full specs. After the ten minutes there
is no visual artifact present, and the flicker fixer is just as good as my
A3000's one. One of the great features of this board is both that you can
render the 24 bit graphics to the computer monitor and you can still have a
flickerless non-interlace display (unfortunately if you wish to output to a
composite monitor/recorder you have to shift back to interlaced/flickering
mode (a very simple procedure – just hit alt-F2 and it toggles it on/off).
The two problems I have is the need to reboot to shift into and out of
"Genlock Mode". From the docs, it indicates that this is due to the
Amiga's requirements, rather than the IV24 board. The second problem is
the erratic computer video quality, while in "Genlock Mode" (which is why
it isn't a satisfactory solution to the first problem, to default always to
the board's "Genlock Mode"). Using a video camera, the image is locked in
well, but using my VCR's video output (fed from it's tuner) causes my
monitor to jump about every few minutes (nothing terrible, just a bit
annoying), and that's not even when it is actively genlocking with the
signal. I am hoping that when I acquire a RGB converter (ordered today)
that this problem will go away (I doubt it, but hope springs eternal).
The image from the board is fantastic. Unfortuantely the simple
software that loads the IFF24 images, distorts these images somewhat, and a
fix is in the works. MacroPaint is far more buggy, and it is very easy to
crash things by using this software for more than ten minutes. MacroPaint
is VERY picky about
