Chris,
Have you actually used Rend24 to produce HAM8 anims? I have and found
that I had to lock the palette. The results were very much inferior to
HAM8s rendered by Imagemaster, or to DCTV pics for that matter. This could
of course be due to a user error on my part. BTW my current version of IM
also has problems with creating HAM8 anims.)
ViewTek is a GREAT viewer! But it was designed for speed and has no fancy
palette choosing algorythms. It was not designed for quality display, but
for quick views of your your files.
>Every DCTV animation I've seen was in actuality an IFF ANIM file.. If
your reference to JPEG-like compression meant the relative size of a DCTV
image to other 'true color' formats, then HAM8 is just as good.
Yes, yes, OK, you've got me there. DCTV anims are of course IFF. I was
referring to DCTV's method of seeing the image as an analog wave form and
storing that analog information in it's file format. I understood that
Jpeg compressions worked in a like manor. But you are wrong about file
size. I took a 24bit 736×482 full color image of one of my students and
converted it to DCTV 3 bitplane, DCTV 4 bitplane, and HAM8 formats:
DCTV 3BP –>106208
DCTV 4BP –>150706
HAM8 ——>323786
As you can see HAM8 files are over twice the size of DCTV 4BP files and
over three times the size of DCTV 3BP files. That means page flipping
anims of over three times the length by using DCTV. And keep in mind that
for the most part DCTV picture quality exceeds that of VHS tape.
>I suggest you start spending less time with DCTV and give yourself a
chance to acquire some AGA software. <G>
I believe I have gotten a hold of most of the AGA software that is
already out there. As I have said, as more AGA aware software (Brilliance,
Dpaint AGA, etc.) become reality I will use it and my DCTV will see less
use. But I'll also restate that if you have enjoyed making images by
pushing paint around with a brush you would love the look and feel of DCTV
