Feeding A Projector Question

[Troy Smith]

Hi All,

I'm wondering what people feed a digital projector with,
if a laptop for example, which format, qt h.264? or something else?
Would need a beast of a laptop to playback h.264 in anything more then
HD res.

Does anyone know what red used to feed the digital projecter at 2k and 4k
at nab?

Any info or insight into this would be appreciated, thanks.

Depends what laptop and what source but 1080p H.264 is pretty solid over DVI from a MacBook Pro for example... I suspect the NAB demos were fed with an 8-core Mac from an AJA Kona 3 but that's just my guess.

I use a DVI to HDMI cable to my Sony SXRD projector. File format meanings nothing.

FYI 8-bit is the best color depth you'll get from a Laptop.

I'm just guessing, but Quvis is linked in "gear we use" on red.com

Probably this is what they used:
http://www.quvis.com/?Action=Products&SubAction=cinemaplayer

Again, just guessing, so very likely wrong.

Thanks for the responses,

What do you mean by File Format meaning nothing?

Which format do you use on your laptop Dane?

Thanks

At NAB we use a KG DPX player over Quad HD-SDI playing DPX files to the Sony projector.

Ted on the road usually projects ProRes out over various links when needed.

Next NAB though... RED RAY will steal the show.

There are many players (pun intended) in the digital cinema playback space. As most of you know the DCI spec for digital cinema projection is only 2k, so there are lots of companies that support that level of playback, most if not all are PC based though. QuVis, Doremi/Dolby, Qube Digital Cinema are some of the bigger players and then Sony has something called the LMT-100 4K Media Block, which is specifically made to playback 4k files.

this area evolves quickly and the best is yet to come...redray should be an interesting addition to the mix.
