RED Metadata for ASA

[StephenMurphy]

Im going to be shooting some tests and a short project on the RED next week and i just wanted to get some clarification on a few points re. the REDs metadata.

1. If the RED sensor is rated natively at 320 asa 5000K is there any value in shooting at a lower asa setting? Will the image be any sharper or any less noisy? Given that my highlights will start clipping sooner i cant see the value myself but please correct me if im wrong.

2. In trying to wrap my head around the idea of metadata would i be correct in saying that the Color Sub Menu is effectively a tool i could use to create a basic LUT for monitoring and dailies?
If thats the case and i was shooting at 320 asa could i use the Exposure range in the color sub menu to create a LUT for what a "push one stop" or "pull one stop" might look like?

4. If i was sending a heavily processed image to the monitors is it possible for the viewfinder to see a lightly processed image at the same time?

5. Is it possible to switch off the gain sub menu altogether?

6. Shooting 4K at 24/25fps to flash cards am i still limited to RedCode 28 or i can i shoot 4K 24/25fps redcode 36 to flash cards?

Thanks,
S

1. AFAI have understood it is 5600. And there's no real value in changing these settings as you shoot (you may need to push them to see in the dark, though)
2. Yup
3. ???
4. Nope, not yet
5. No, but it doesn't gain @ its default
6. Seems some people have problems, others not. TRY!. Limit yourself to 2:1 as of now. Lots of people having problems when shooting 4k 16:9 (to disk or flash)

Steve - Can't comment extensively on the low asa setting but Gary in Screen Scene noticed that the "white" clip was happening at around 80 percent on low ASA shots (now this was build 13 - which I also noticed in the finder - the blown highlights in clouds went "grey") - At 320 all was normal in terms of white clip - Build 15 may be different (testing with Big Des tomorrow so will check that).

Also Build 15 4k at 16x9 has a QT proxy error (garbled lower half) - R3D files okay though but just FYI. All okay at 4k 2:1

Not sure on the others - i think the camera outputs one kind of image only though. I'll check gain sub menu tomorrow.

ps - Hope that shoot went well for you guys.

Later
