Chris,
The quality problem with REND24 only happens when rendering an anim,
which I found required a "locked palette". Which brings up another
question. There are NO palette concerns with DCTV. I would think that
unless the next generation animation software supports palette changes on
the fly, then HAM8 anims would suffer if they were forced to conform to
the palette of the first frame. There is also the issue of compositing
images with very different base palettes. Since DCTV seems to work with 24
bit internally, and there are no palette concerns, compositing in DCTV
paint is a pleasure (aways save in 24bit format and you'll have no NSTC
artifacts in you pics). I've heard that Brilliance also maintains 24 bit
accuracy internally. I don't no about Dpaint.
Yeah, you got me again! ( I hate when this happens 😉 ) The HAM8 file
was hires since I converted directly from a 736×482 24 bit file. But
saying that DCTV is also lores is true, but not the whole story. From what
I understand DCTV take all the image data of say a hires 24 bit file
rendered in Imagine and displays as an NSTC analog picture. This analog
information is what is stored in each DCTV file. So since NSTC video is by
nature lores – so are DCTV pics. That is not the same as actually
converting a hires bitmap to lowres bitmap where choices have to be made
as to what pixels to leave out. Will a lores HAM8 look as good as a hires
pic displayed by DCTV? I don't know – I'll try some!
BTW I've heard that Dpaint AGA is shipping. I'll try to order mine next
week!
