LCD format
I was wondering if anyone knew what the ideal/recommended file format would be to project with an LCD projector in a cinema, via a network. We are looking to implement a new system within a few months that allows us to show content from a server, but aren’t positive yet what format(s) will yield the best results, and don’t have an estimation of filesize (for, let’s say, 10-15 min of high quality content).
“The projectors are higher end 3 chip LCD ( not digital but having an HD palette ). They are high resolution multimedia types we are looking at. They are going to be state of the art so I would assume that SVGA or DVI or HDMI inputs as well as component and composite inputs are going to be available.
The cpu should have a high end stereo or 5.1 – AC-3 output sound card and of course a very nice video./ capture card as well. As far as format, that would be user defined. ( Its up to them )” -

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

Why are you installing “multimedia” projectors in a cinema environment? Multimedia projectors are optimized for computer presentations (PowerPoint, etc.), not video playback. If your application is a multipurpose convention center type environment, then so be it, but if you are mainly going to use the systems for the projection of video material, I would strongly suggest you rethink using general multimedia LCD projectors and instead research native 1080p digital cinema projectors, even if they are higher end home theater models.
You don’t state what video format you’re going to be primarily showing – will it be SD or HD material? If it’s mainly SD, then a multimedia projector would be adequate. HD however, would be much better served by a native 16:9 1080p projector.
Most multimedia projectors are native 4:3 and top out at SXGA resolution, which is 1280×1024. That would allow you to play letterboxed 720p at native resolution, but any 1080p footage would be downscaled by the projector.
H.264 is a great codec for low-bandwidth delivery at a high level of quality.
