DL not sure DL I agree about using the toaster for porting animation to NTSC
since DL> the PC has a very nice complement of hardware for broadcast quality.
No, not the Toaster. It has nothing going for it in terms of real-time
playback of animation.
DL> Talk to me. Why is the Amiga better DL> at porting to video vs. a targa+
system?
Don, a Targa+ is very nice, but how can it help you get 24 bit graphics to
animate in real time? Once you drop below 24 bits, you have palette and dither
processes to contend with and these lead to problems with images tearing.
Right now I have a VLB 24 bit card in my 486-33. I checked out a program
called F16 by Rainbow Technologies that enables you to play back 16-bit anims
in real time. What did I see? As long as the delta values are low, all is
well, but when large areas of the frame change between frames, the images do
not flow smoothly. To get it right at this point, you need a single frame
capable VCR like the Panasonic AG7750. (cost $4800 plus you need the TAO
editizer or some similar device (add another $1500). Plus the Targa card
($1400).
On my Amiga 3000, I use a little 24-bit display device that sells for (get
this!) $299 called DCTV. It is a device that is totally unique to the Amiga
platform and it works without any JPEG or MPEG compression. It uses a special
4 bitplane dispaly technology that enables huge amounts of video data to be
coded into very small files. A DCTV full oversan animation file that lasts 120
frames with a moderate level of change between frames might be as small as 4
megs. The best part of it is that you can playback from RAM in real time and
get over 30 fpsin anim7 format. It is a wonderful device. So, I record
something that looks a helluva lot like 24-bit animation on my $970 AG1960.
And they are good enough for most local TV and industrials. Get some Amiga
buddy to show you the DCTV in action. I have been using strictly clones for
the last 7 years and I was on the
