Thanks Chris and Kris and Daniel.
I’ll research further. Multiple VBR passes is likely only the beginning. When I shot the explosions for the train sequences in Ghost’s of Mars, we really did shoot a shallow depth of field. we were afraid the flash from the explosions would light and expose the seams in the black cyc. as a result we did get a grainy dark negative. But that’s what John wanted.
I’ll let you know if I make any headway with this compression issue.

Hey Daniel,
Thx for responding. I’m a VFX Supervisor and have full ap scans of our finished negative for Ghost’s of Mars as well as TIFF HD frames for lots of my Showtime Projects. I’m trying to create a demo reel in QT.

I’m wondering if they selectively reduce the bit depth for each sequence before compressing, similarly to log to lin conversion with Cineon files. Dunno… But I GOTTA get a handle on this.

Yesiree Bob.

Weird, but this update didn’t show up for me till I went looking for it… Thanks for your help! 🙂
