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

• DCI Spec 4096 x 1714 2.39AR

• Garbage in last line
• Solve by doubling and trimming to 1712
• Rendered out fix frames 2048 x 856

Dont Presume AR !!!

Tools Need to be as easy as video

Human errors too ?
