Digital projectors

All digital cinema class projectors will do a minimum of 120fps at full frame and 144fps in a reduced picture size (with the lens zooming up to full frame). Some models with newer boards will do 144fps full frame. The issue is that there is no standardised way of feeding them more than 24fps in 3D stereoscopic 2k resolution. The DCI forum are working on it, but right now no server supports decoding of JPEG 2000 at more than 48fps (24fps x 2).

Looks like another round of server upgrades for cinemas (~$15k per screen). And very likely there will also be a 24fps deliverable for those who don't upgrade.
