Are you serious or joking?? That would be awesome if you were there.

Saturday December 9th at my new home in St. John, Indiana.

We will have JUST moved in so the house will be in disarray, but drink will be plenty.

The SmX has a perfect off axis performance so this should help if I am understanding the problem with blending on a gain screen correctly. You can go 80 degrees off axis and it looks the same.

Im not sure the gain numbers on the SmX are pure science or if there is such a thing, two differnet people can come up with two different results and have, one said 0 gain and the other guy said 1.16, regardless, it looks darn good up against a Stewart Studiotek 130 without perfs. We had people that knew nothing about screens or could care less pick their favorite and it was about 50/50 with most saying " is there a difference?"

heres a pic with the SmX hanging in front of the Stewart the way we tested and we had black fabric behind the SmX to duplicate the open black space behind




heres a couple videos of the original material before it was improved with a tighter weave (much better results) but they give you an idea of how good it performs, remember its shot with a camcorder so the results have bloomed whites that appear blue, this is the nature of this camera not Stewart or SmX, it also had troubles focusing sometimes but what can you expect shooting a 14' screen

I expect that the rating of 240 ANSI of one M9500 is about doubled to the 480 ANSI range, and I did not exceed 50 on the contrast to have it...... :-)

Mark,

That is one hell of a theater you have there. I remember following your thread.

SMX I truly feel is the material of choice for my stack when I do it and I think it will make for a GREAT example for the Blendzilla meet.

Thanks much for the info!

Dave,

It would be nice if you could make it! Much has changed in the area.

Although the conditions surrounding the screen at the meet will not be ideal, I think it will be ignored once the demo's start.

I wasnt aware DVX could do 1600x1200 @ 72?? Did I miss a firmware update Tim? I thought at that resolution it was limited to 60Hz?

You could try 1400x1050@72 though

Cliff, try all 1024p, 1050p, 1200p... I found that I couldnt really see a difference with any of these... also, will you have an external video processor also? I find using the VP50 to the DVX really improves on PQ

Gino,

I was under the impression that it will do 1600X1200@72hz per projector? I guess Tim will have to chime in on this one. If not, I can stick to 60hz. Anything under 1200P at 4:3 on a G90 will reveal visible scanlines on a 12ft wide screen hence me wanting to use the G90's "sweet spot".

Guys!

Here is what the controlware allows one to click on:

1280 x 1024 at 50 60 72 and 75 hz refresh

1400 x 1050 the same

1600 x 1200 at 50 or 60 hz

1920 x 1080 at 50 or 59 hz, not sure if blend capable need to try some stuff

I'd go with 1280x1024 @ 72 Hz for NTSC film-sourced material.

If the DiVentix does not support IVTC for HD sources, use an external processor to do that and feed the 1080p24, 1080p48 or 1080p72 signal into the DiVentix for blending only.

The two new tubes came in last for the 8500 (thanks Tim). I've been way too busy to get them in the unit, but can't wait..

This is one setup I'm really looking forward to doing a screenshot session of..

Got ruby?

It's all about the performance... Got Marquee!

So Mike, you really should fly out with Clarence when he comes for the meet. You really need to get your hands on a G90 so that you can see first hand why he is KING.

Tad disappointing to hear that Gino is getting his best results when using processing from VP-50 prior the DVX 8022. What is going on with that?

There were many questions a few months ago about how DiVentix did de-interlacing, but not many answers. Sounds like the VP50 simply does it better, which is not too surprising as it's the state of the art. The better Crystalio, Lumagen, Optoma or Vantage processors would probably do a good job too. An expensive hardware blender can't keep up with those sorts of developments.

That's why I think switching/de-interlacing/scaling/noise reduction/picture control etc should be kept in the VP, and splitting and blending just left to the blender.

If the DiVentix is just bobbing or scaling 1080i video (like the VP30 for example) then it may not give you a better picture than say, a VP50 driving a stacked pair.

We asked Analogue to tell us a bit about their technology and they declined. Multi-box systems are quite cumbersome so a one-box solution running one firmware controlled by one PC is the friendliest solution in my opinion. 480i sources have their inherent limits so if some other scaler handles that better then so be it. My base DVD player here is an HTPC and looks fabulous for that use so I cannot grumble about Gino's setup!

One comparison I will be able to make though is between the deinterlacing between the DVX and VP50. Once my projectors are back up and running (Tim - do you have those 2/4/6 pole magnets for me?), I'll be able to hookup the XA1 at 1080i60 direct to DVX, and also compare it to 1080i60 deinterlaced to 1080p60 by the VP50.

Tim,

What is your suggestion for me at this point with things getting closer?

I REALLY DONT want to run the G90's at 1024P. They will spit that up, eat it again, and then crap it on the floor. It's really not the optimal resolution for a G90.

If I run 1200P in 4:3, the picture will be the bomb. Albeit, there will be scanlines, it will not be NEARLY as bad if 176 lines of information were taken out of the equation.

Can we do this and the deinterlacing be within spec of what the demanding videophiles coming to the meet will expect or do I need to put the VP50 in the mix........ ????????

Why 1080p60? The VP50 will output 1080p48 (dunno about 72).

Gino - do you see that increase on PQ when using HD-DVD? I would suspect that if you output 1080p24 to the DVX and then output 72 Hz to the PJs there is no deinterlacing in the equation.
