HATVista/Illuminator?

Ihope someone can offer a little advice as to which framebuffer I should get. I currently have a Targa+ 16/32. I have ordered a Diaquest DQ-422+ and a Sony UVW-1800. I am considering either an ATVista (with a PAR for previewing); or a Matrox Illuminator Pro with the Animation Express option to accomplish the same thing. I'm leaning towards the Illuminator because it offers (Y,R-Y,B-Y) color difference output to match the UVW-1800. However, I have been told that the Illuminator exhibits some color banding (something about the encoder/decoder). Also I learned the Animation Express is an EISA board. I guess I needed another machine anyway. Any suggestions? Todd

Todd, This may be another issue: I thought that Diaquest did not support the Matrox board, but do support the Truevision cards (Targa, ATVista, & DVR series). Kevin Krell – Computer Support Associates

According to Diaquest the DQ-422 will support the Illuminator Pro, Quick Pass, however will not. Thanks for your response. Todd Dunbar

Todd, OK, it was the non-QuickPass support that must have triggered my alarm. Kevin Krell – Computer Support Associates

Thanks for the info. Someone else suggest that maybe I should forget the ATVista/DQ-422 combination and use the PAR for all output. What do you think? Todd

Todd, It's doable, so long as you don't need the ATVista for any RGB input, or for use with ATVIsta applications (Hi-Res QFX, TIPS, Lumena, RIO, etc.). Ultimately, an ATVista with an appropriate encoder/decoder/transcoder will give you better quality in a broadcast setup. The PAR output seems to be acceptable for all other circumstances. Indeed, you could probably start with the PAR & add a Vista board later if you wished. Kevin Krell – Computer Support Associates

Kevin, Thanks for the swift reply. I have already ordered the ATVista, DQ-422 and a transcoder; so I guess I'll be set for just about anything that comes my way. I've been talking with Don Landis. He uses the PAR for all his output and thinks that it works fine. I'll probably do the same for most jobs (and keep the frame accurate hours down on the UVW-1800). I just wish there was at least one vendor in the southeast who had actual experience with the PAR and could have at least mentioned that I could record "acceptable" video from it before telling me that I should go with the framebuffer/diaquest combination! Oh well, I guess a plane trip west and a couple of nights in a motel to find a dealer with experience would have cost the same. Thanks again for you help, Todd Dunbar

The Illuminator Pro has banding, but only in the Y-C and composite outputs, and there is a chip upgrade coming out shortly to cover that. I believe the CAV output is flawless… at least it appears that way on my Illuminator Pro. And yes, the MAX requires an EISA MB, plus an adaptec 274x or 174x scsi controller with seagate barraccuda hard drive. I'm getting pretty impressive @ 4.7 megs per second write and 5.6 megs per second read times with the MAX and my setup. John Tissavary (LUNA cie)

Use the PAR for all your output to the UVW-1800. Dump the diaquest bd. and get a TBC IV for frame grabbing real time. The AT Vista will still have some uses as a good quality frame buffer even with a PAR. The PAR has betacam component out.
