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

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 !!!

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

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
