Eric, I hope you don't mind me piping up, but I couldn't help notice that you
have Mediaspace/DVA4000.
I've never seen the capability of a Targa, an Amiga, or any of that stuff, so I
can't comment on that. I have read that these boards can do some really great
quality recording, but for making software demo tapes or training videos, I
think Mediaspace is definitely up to it.
I use Videologic Mediaspace & DVA/4000 too, and I have had some luck with it,
although I admit there was a steep learning curve in the beginning; it became
more of a case of building components around Videologic's boards as much as
building a system!
For what its worth, I have some insights for getting the best out of these
boards that you can while minimizing the cost of additional hardware. Also, I
have had good luck with Orchid's 1280 plus VLB SVGA card, but even that took
some fine-tuning.
I think that the output quality depends somewhat on the system's ability to
download video to begin with, as measured by Vidsnap's calibrate reading, as
well as the refresh rate. Another thing that's important is what device you
use to output the video to vcr. I use Videologic's Mediator LC; it's nice
because its external (has both red AND green lights)(perfect for Christmas -g)
and has controls on the side to adjust picture. And most importantly the
picture quality is good.
If you are going to do a lot of insets, then Mediaspace can be really good at
that, since most PCs tend do get a higher quality video recording rate using
Mediaspace at 320 X 240 where the hard-drive and CPU can work optimally to get
a really good quality "take" off your video source. 640 X 480 recordings need
pretty super-human (PC?) kit to manage the data transfer rates at that setting.
A Pentium/PCI system is out, sadly, because Videologic claim that the PCI buses
out there are not standardized enough to work with the VGA standard set forth
by IBM. It's a lame excuse, but there you are– The DVA/4000 won't display a
picture with a PCI video card. A DX4-100 with vesa local bus video and vesa
local bus hard drive is what I would suggest. I read about a Pentium 90
motherboard made with Vesa Local Bus that is now out of production because it
doesn't rate as a motherboad compared to the newer PCI boards, but for
Mediaspace, it could be perfect; after all, what you really want the Pentium 90
power for is non-linear editing in Windows.
As for your technique, have you considered attempting to use some sort of
software frame-grabber (like Hijaak or something) to convert your PC's screen
to bitmaps, turn that into a video, and then position your video clips on top
of that using Premiere?
Anyway, best of luck finding what you're looking for. If you do put together
the killer system, be sure and post it!
