DLP Projection Standards

It sounds to me like he's talking about this: http://en.wikipedia.org/wiki/Digital_Cinema_Initiatives

You would need to create a DCP, if that is what he's talking about. Learn more here: http://en.wikipedia.org/wiki/Digital_Cinema_Package

Honestly, it's not particularly easy to do, though it can be done yourself. I think someone did a huge writeup here on REDUSER.

The bigger issue you'll have is that the color will be wrong, unless you're already using the P3 color space to do your color correction (and have an appropriately calibrated DI system to do it on). So, this is probably not the route you want to go down if you're not already doing a DI...

Wow this sounds ridiculously confusing! lol What format would I use? .mov with jpeg 2000 compression?

and as far as the XYZ colorspace goes...i've exported an uncompressed 10bit 4:2:2 file, will a new color space destroy my current color grade?

Based on the questions you're asking, I can tell you with certainty that you should NOT go down the flash drive route.

What you need is a video playback device you can plug into the projector. Talk to him about that instead. He may already have something (e.g. a blu-ray player), or he can tell you what input you can plug something of your own into (a DVI, HDMI or HD-SDI input).

Laptop, BluRay, WDTV, all nice and valid solutions for a range of applications. But if you're going for top-quality these are simply not good enough. Look at your gradients/sunsets in an 8bpc cage.

Usually external playout devices would connect to a scaler, not directly to a projector. So in addition you/a projectionist need to deal with setting that up -- which could be painful and need not necessarily lead to the best possible results.

The beauty of the digital cinema platform (in the form of DCPs): Send it anywhere and let someone hit Play. Also it's not rocket science as has been suggested.

You could probably get a good quote for a music short from a facilty near you and hence preserve the quality your red material deserves.

I agree it's not "rocket science", but it's also not at the level of "export a .mov", which is where the OP is at.

100% agree. Please don't try to make a DCP yourself.

P3 is the Dolby 3D color space. Everything 2D or on another server in 2D or 3D is in XYZ color space.

As far as making your own DCP its very doable. A friend of mine over at Warner Bros. made a DCP of some of my timelapse that he just downloaded from Vimeo. I saw it projected a couple days ago and it didn't look bad considering the source. He made the DCP using all those open source codes and such. The color also looked pretty close to what I remember seeing.

I know that over at Warner Bros. we have a FCP system up in some of the screening rooms that are connected to the projector through an Aja card and that works great. But I believe most digital projectors have a DVI input and if that's the case at the place your going to be screening at I would say just bring in a computer to do the playback. You should be able to set the projector up as a second monitor. Granted getting sound to playback might be a problem using this method.
