RED Projector...

[Yannick Verry]

Any plan for an optional anamorphic lense ?

[Roberto Lequeux]

Agree with you 100% on this issue Aaron.

Existing lamp technologies are a major pain to deal with, both financially / operationally and from heat / environment points of view.

Stuart, roughly, how long and stable is the life of lasers in comparison to regular lamps?

[Richard Gale]

Did RED ever show off that projector yesterday? I had heard that they were just going to be using a Sony PJ, but I was crossing my fingers anyways just in case.

Edit: I see that just a couple posts above me, someone says it would be a Sony PJ. Is there any confirmation of this?

Yes, that was a Sony 4K projector at the Open House.

ambient light will always be an issue. Most people end up going with a higher gain screen like a dalite HP 2.4 gain screen.

The problem with going with high-gains screens is that they tend to introduce color linearity issues. To me, the E.J. Stewart StudioTek 130's are the way to go -- very flat field, no hot spots, perfect for a small-to-medium-sized grading or screening room (say, no more than 12 people). Ambient light is not an issue if you control the environment (i.e., enclosed room, dark fabric on the walls, no light spill, high ceilings, etc.).

3D is a separate issue.

I do agree that if Red could create a modestly-priced laser-based 4K projector, it would radically change the business, especially if they could do it for (say) 1/10th the price of competing projectors from Barco, Christie, JVC, and Sony. And even more, if they can come up with an economical solution for 3D brightness compensation. Lots and lots of companies are struggling with that right now.

The Main problem right now which is unknown is the bulb. Most of JVC 3d Projectors have issues with 3d after 400-500 hours of bulb use. As the brightness drops the active shutter glass become out of sync and 3d has to much ghosting crosstalk.

That is why in my post above if they build it modular and customers can add another light engine for brightness, then there are no issues with 3d.

What has lamp age and associated brightness loss got to do with staying in sync??

Brightness drop off and associated issues is exactly why we chose to build our light engine around lasers ....

For some reason with the JVC 3D Projectors as the Bulb Ages the ghosting/crosstalk get worse. There is no proof for right now why it happens. Brightness should not effect the Crosstalk.

The theory is that when the bulb is warmed up it heats the LCOS panels allowing the pixels to shift quicker. As the bulb ages the pixels do not shift as fast since the bulb is running at a lower temp. Which means more ghosting/crosstalk if the panels are moving at a different speed the the active shutter glasses.

If you visit the other projector forums you will see that everyone recommends a 30-45 minute warm up time with the JVC 3d Projectors. That is helps reduce Ghosting.

Is this exclusive to JVC or common to panel type?

[Aaron Fritz]

I have the JVC X3, and after 400 hours you could not watch 3D on it at all. I took it in for servicing and they gave me a new bulb. It seems to be the same case with most JVC users.

I don't know if its panel specific, or as the temp goes down of panels the active shutter and the panels get out of syn (just the Theory).

JVC just released there new 2012 Projector Lineup claiming better 3D performance. I had the pleasure of testing one out and being able to compare it side by side with mine. The 3D performance is the exact same. It has the exact same amount of ghosting/crosstalk.
