9 Compression – easier, but…. n Kakadu software encoder on 100CPUs –A few glitches on write-out to SAN n Batman Begins –“black frames” –24-bit quantization of 4K layer –Chip firmware change coming
10 Tools – Need to be as easy as video n 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 n (PS – BB scan = 4096 x 1712) Don’t Presume AR !!!
11 Tools – Need to be as easy as video n 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 n Render out color timing –6 frames off n Conflict on equipment –Accessible by both US/Japan –Insufficient space But fun with a great team
