>> transcoder for the ATvista to Betasp
A pretty good one is the Grass VAlley CV-22 retailing around $995.
Paul Lind just got one, Paul, how do you like it?

Will a good transcoder help a Targa+ using the RGB to transcoder to SVHS?

Always, the better the quality of the source, the better the images. A
better transcoder will help, but remember, with the Targa+ you are limited
to 512×486, it will never be a Vista (756×486)!!!
I'd recommend borrowing one first to test yourself to see if it helps
enough to spend the money on.

(Pardon my jump here)
Boy, now I'm REALLY confused. If you're going to SVHS, I didn't think
resolution (of the image) mattered, past 640×480. I've tried higher
res and I don't notice any difference — how can I, when the video
res itself is only 640×480?
Are you saying that when I render my TGA files (for ultimate dump
to video) that I should be rendering at a higher res than 640×480?
(NTSC video).
I your rendering out from an ATVista, as far as I know, an 640×480 image will
produce black bands on either side of your image because 3DSr2 won't rescale
the image to it's proper resolution (756×486) and aspect ratio (0.8571)(Release
3 I've heard will though). I use a service bureau to render out to BetaSP, so
I render everything to the null at 756×486, AR 0.8571. and dump everything to
SyQuests. At only $75 bucks an hour I can usually get 240 frames per hour
transfering to tape.

Sure it does! Anything you can do to get more pixels on the screen will
result in a higher quality image!
756×486 has 30% more pixels than 512×486! That translates to 30% higher
resolution!

You should render out to the highest quality that the equipment will take
advantage of. Vista resolution can take 756×486 out to video, Targa is
512×486. Depending on your board, or service bureau, go with the max!

I was just curious, it seems I had seen comments about the Targa+ encoder
leaving alittle bit to be desired.

What an understatement! <g> But it is a step above their VidI/O box!
The Targa+ going out straight RGB to a laserdisk or to a transcoder does
well for 512×486, though!

I have a VP procedure I want to do. It is a simple fade between two images,
then a wipe of a title across the bottom. The fade occurs over the first 20
frames and the wipe over the next 60. The wipe is done in the usual way with an
animated opacity map. Here's my problem. How do I get it so that the animated
opacity map doesn't start animating until fram 20! I mean, I know how to use
the sliders to start the procedure there, but it seems to have been counting
down the frames so that the first frame of the wipe is using the 20th frame of
my opacity animation. Does this make sense? Apparently, VP starts counting
animation maps from frame one, not when they are actually started according to
the sliders…
Doug – PMJI. I'm not a major expert on VP, but I'm pretty sure it starts all
your animations from the get go and just does the indicated process during the
frames specified. Presumably your animated opacity map is black and white
(Maybe w/shades of grey [or gray]). I'd say tack 20 frames of total black on
the beginning of your opacity map animation. Then it can use them all it wants
and there will be no effect. FWIW
David Taffet
I did that, thanks. It worked fine too. But since I use this same map in many
different animations, it is a pain to always be adjusting it…
>a pain to always be adjusting it<
agreed

Doug,
Try moving that sequences' dot with the shift key down then it will move the
whole sequence in time.
James
You mean the black dot instead of the red one? Thanks!
Doug,
Yes, the black dot determines where the first frame of the sequence goes.
James
Woah! Good tip! For those of us who didn't RTFM intently enuff…
David,
Geez, there are some who claim I don't even read the manual<g>. No, seriously
the user manual is a permanent addition to the room where the sun don't shine.

Seems like you got some pretty good responses here on ASOFT! If you need
anymore help, just holler!
