>> with the MAX slightly higher quality (3.5 MB/sec vs. 3.0 MB/sec). FYI, I am getting 3.6 MB/sec using a Seagate ST 3655A with the PAR. It doesn't invalidate anything you said, just gives some feedback as far as the PAR goes.

Gus, >> I am getting 3.6 MB/sec using a Seagate ST 3655A with the PAR Cool! Sounds like we are getting a lot of good options. BTW, how much of the disk (how many MB's) can is "rated" by the PAR for that performance?

I was told 2/3 (of any disk). I never got that far. It's also good to point out that very rarely a scene takes the full bandwidth. Unless you have a terribly busy scene. Most of the stuff I've been playing with resulted in files so small (with maximum QFactor or greater quality) I haven't reached the drive limits (by a long shot). That, however, changes very quickly when you record live video. Specially a shot from a camera attached to the helmet of a guy running cross country with a BMW Paris-Dakar.

Glad you're back. You can correct all the erroneous stuff floating about the forum re the PAR and what it will and won't do. BTW I ordered mine last week and I guess I'll order the HD, a Micropolis 2210A tomorrow. I also ordered the TBC4 and remote, for full frame grabbing. Do you have the TBC4 and if so how does the frame grabbing work for you?

Don: I captured the LucasFilm THX demo disk on the TBC4 to the PAR. Almost five minutes of action, looks beautiful! Alan Iglesias and I A/B'd it and were absolutely amazed! Greg Pyros

It's refreshing to get response from those who actually have hands on experience with this stuff. I'm still without specific information on the resolution problem but maybe after tomorrow's meeting I'll get some answers. Sunday's session was a waste of time for technical info. I have a feeling that someone in their organization has commited software specs they can't deliver. The claim was 640x480x24 bit at 15 frames per second from a CD-ROM. I don't think it's possible. I'm getting a little impatient and so are the investors on this project. The technical guy keeps showing up with missing information.

Really! My eyeballs are still hurting from trying to find some sign of lossiness in the frame/field play back of the grabs<g>…The dang thing certainly seems to work well… -Alan

>> Do you have the TBC4 and if so how does the frame grabbing work for >> you? All I've done with the TBC is grabbing color bars or random noise (aside from some shots of a couple of CG Laser Disks). The stuff I wrote has nothing to do with the TBC. All I needed was a way to create huge files in order to dissect them. I really haven't had much time to do "normal" work. Greg, on the other hand, has used his TBC it a lot more than me. The one thing I did was to record some live video and run the scene through some of my IPAS'es. Just get one frame at a time, run the process and save it back. It's pretty cool. I can't wait to see the Xaos stuff.

I recently read a message here that the PAR can't do output at 30 frames per second without tearing. That only the MAX has this capability. I'm sure if the picture was tearing then you would still be in development, right? Thanks for the facts.

Don: Don't know where you saw it, but the PAR has NO TEARING whatsoever at 60 fields per second at 24 bit at 752×480 resolution! (Did I make that clear enough? <g>) Greg Pyros

A message from a somewhat crazed 3DS user: When! When! When! When! When! When! When! When! When! WHEN! All this talk abot the PAR is driving me CRAZY! I want it RIGHT NOW! –Nat'n:-) ->Sigh<- (I just needed to get that off my chest….)

Nathan: I heard February 1st. The TBC-IVs came in today, so things are happening! Greg
