Kevin, some valuable comments indeed you've made about the Ursa Gold.

I don't know if the sophomoric backgrounds I generally get would
benefit. I understand what you mean; I've had visible quantization
with some backgrounds. What size transparencies are you transferring--
35mm stills (so aspect ratio is as Super35mm)?

Does this mean that you sometimes record the Ursa Gold's output
pre-color corrector? I would think you'd always go through the color

This I also heard about the original Ursa, particularly from New York
City operators & engineers. In Los Angeles, the Ursa's strengths
outweighed, and noise as an issue was swept under the carpet.

Hmmm. What sort of horizontal stabilization are you using: ceramic
skid plate, or spring-loaded roller? By "15 layers", I presume you're
talking about exacting composite work. I don't mind saying I find
your statement extraordinary...but maybe with a transport that's set up
absolutely right, along with Jumpfree...

Can you tell me what the Henry does now for stabiliz(s)ation? I
wasn't aware it had the capability. Flame, yes.

Me too. Chime in, others.
