Color – The Men of Black Magic Color space P7v2 ≠ P3 ≠ P3 Corpse Bride

– US release P7v2– Realized color didn’t match exactly,

but not obvious due to stylized movie Harry Potter 4

– US release P3– Projector/Master white points not a match– LUTher box used on external DI

Compression – easier, but…. Kakadu software encoder on 100CPUs

– A few glitches on write-out to SAN Batman Begins

– “black frames”– 24-bit quantization of 4K layer– Chip firmware change coming

10

Tools – Need to be as easy as video VDC/Pogle render out on HP4

– DCI Spec 4096 x 1714 = 2.39AR• Rendered out 2048 x 857• Garbage in last line • Solve by doubling and trimming to 1712

– Rendered out fix frames 2048 x 856• Slightly zoomed-out (shrunk) image

(PS – BB scan = 4096 x 1712)

Don’t Presume AR !!!

11

Tools – Need to be as easy as video Test playout

– Tools to check amidst color/compress/encrypt/wrap/project

– Pause, step forward/back• DCI spec requires restart on reel boundaries• Created 2000 frame reels

12

Human errors too Render out color timing

– 6 frames off Conflict on equipment

– Accessible by both US/Japan– Insufficient space

But fun with a great team
