So I got word today that my local theatre will be showing a music video I directed for the artists CD-release party. I shot the thing on RED-MX and am wondering if there is a place I can find the standards for DLP theaters. I'm particularly curious as to what format, codec, and bit-rate I should finish with.
Does anyone have any idea?

Check with the theater manager to see what they have installed. Most projectors have multiple input options, HDMI/DVI digital, RGBHV/VGA analog PC, YPbPr/YCbCr component, S-video, and composite video. Best option would be Blu-Ray or Laptop HD format via HDMI/DVI if possible. Interfacing to the audio system may be more of an issue. You need to find out what the input options are there too. Pre event site visit to figure out what you need is mandatory.

Cool. Ideally, I'd like to export this to a flash-drive or harddrive as I don't have a blu-ray burner.Originally Posted by David Rasberry

A lot of digital theaters have DVD players installed or interface points for computers to support rental functions. Some have servers for ads that you may be able to load your video onto.

But note, they usually also have a separate projector for these sources (which is generally a consumer grade projector used for local advertising). The only way to to play to the DLP's is from a DCP

It really depends on the particular projector installed and what input options are included. The big DLP's all have modular input options. A DCP server outputs standard dual-link HDSDI format digital video to the projector. But the projectors can accept multiple input formats. Connecting a laptop to one via RGBHV analog or DVI is usually not a problem. Access to an audio interface to the house system may be more of an issue than the projector.

every cinema is different, as David suggested in his first post you really need to talk to the manager of your theater. From my experience, most local theaters only have DCP servers on the 2K or 4K projectors and you must use their smaller projectors for "other" content.

Getting a file into their server will be extremely difficult. Don't even go down DCP path. It's not worth it. Bring your own player of some type. Lots more ways to make it work that way. All of the high end cinema projectors I have worked with have a variety of useful inputs like HD-SDI, DVI and RGBHV. But the controls may be locked out and require a password. The local projectionist may not know the password or what even to do since they never change any of these settings. I like the WDTV as a cheap 1080p 24fps player of like 25Mb Mpeg files or 20Mb h.264 files. Look for the WDTV version that has component video as well as HDMI. This player is a great $130 backup plan. Bring an HDMI to DVI adapter as well. I've also seen several film festivals use mac-mini's as video servers. Your laptop might work.
Blu-ray could be an option as well.
As others said, sound could be tricky. Having a small audio mixer with balanced XLR outputs, unbalanced 1/4 inch jacks, and RCA outs could help.
Test everything days before the event at the theater if possible.
My bet is that the cinema projector will take just about any signal type you have, it's just that the theater management won't let you touch the thing since they don't have a clue how to set it up and are afraid you'll change a setting and they will not know how to get their movies back.
That being said, I had a friend use his RED via HD-SDI to a cinema projector to playback RAW R3D files to show a producer what RED footage could like in a theater setting.

In most cases the theater is not the exclusive owner of the projector, distributors are involved with special financing and contracts.
That´s the reason why nearly all "consumer" inputs from a cinema DLP are restricted and deliver in best 720p. The only HD SDI input delivers FullHD.
But as others said get in contact with the manager, all is different...
The small tiny WDTV also was my first thought, H264/30Mb/s should look impressive, but was disappointed because of only 720p. Finally had to play out with HDCam

Some time ago I use a MBP and esata drive via DVI to DVI and woks fine, the hell is to calibrate this output but if you have time you can put it really close to your FCP sequence.
With an AJA or matrox solution you can calibrate more accurelly. If you never encapsulate a DCP, much better do this way. A well laptop gives you more advantages, think about the end of the reproduction with a media player...
good luck!
Vico.
