Arri DR Test...

[David Mullen ASC]

Sort of the whole point of the modular system, isn't it? You simply replace the whole brain, which contains the sensor and processor.

 

[Michael McVicar]

You always want to originate with more range than the projected image -- due to the need to create a solid black on screen, there has to be a lot more gamma in the projection format. But obviously in film we don't shoot color reversal, which has projection contrast built-in, because we need to be able to color-correct it, copy it, etc. Same goes for digital, we need some flexibility in color-correction to throw some information away, otherwise we have to shoot everything exactly for how it will look projected.

For some reason, I doubt you are going to run into an ASC member using those words in an advertisement for anyone's product....

I thought that push processing was a standard lab photographic procedure.

But it was pretty clever ...

Definitely. Maybe Red could do some TV spots with the tag "More cushin' for the pushin'..." with a Barry White song playing in the background. hmy:

With R1M or R1MX R3D files get Red Rcket card, Wave console and any of wide gamut LCD monitors

then with that set-up you can "play" PUSH & PULL GAME in REDCine-X using FLUT™ knob from Wave.

Just to have a feeling what is DR (13.5 with MX R3Ds).

 

[Andrew M.]

15.5? Yeah baby!!! YEAH!!! :sifone:

Jim, a few questions if you may. Does 13.5 come from a 2k down-conversion? Are you still pushing ahead on M-X? Think you can get an other hair out of it?

:emote_happyhappy: :emote_happyhappy: :emote_happyhappy:

Processed at full resolution. In theory, downscaling should be able to eek out a bit more.

Noise level is much more acceptable by about full stop after downsizing from 4K to 2K when it is done properly.

Takes a lot of fooling around with noise reduction though.

If only Graeme had some spare time to do NR 4K->2K button it would be fully automatic one extra stop of DR.

Doing NR after downscaling doesn’t give good results.
Sometimes I wish to have NR on 2K output with NR info from 4K original.

The decision of NR for single 2K pixel should come from 12 pixels of 4K original not from 8 pixels of 2K result.

To air during SuperBowl 2011 (shot on Epic and probably should be 3D).

You make a very good point. The NR step would have to be handled by the RED Rocket as a metadata setting, otherwise NR would have to be applied at full resolution by the CPU, making downscaling also have to be handled by the CPU... bye bye RT.

Unfortunately, it might be beyond the might of the RED Rocket's original hardware design...

Graeme? Are you planning on developing something like this? Is it possible off the RED Rocket?

Rocket is not my baby :-(

We don’t have to have it as a real time feature. I would be quite happy having it as a filter, like your famous Big Box of Tricks plugins. I will call it 4K->2K deep shadows filter.

Theoretically such arithmetic approximation should give us two extra stops of DR in blacks but if we get only one extra stop on top of 13.5 already there, looks to me like a free lunch.

Who's is it? I am sure they would love the idea of running some of your high octane sauce though their supercharger.

Same thing but for cleaning noise in deep shadows in 2K downers using info from 4K original.

Deanan and Rob look after the Rocket.

I'm sure the engineers would frown at me if I showed them the algorithm for that stuff.

[Andrew M.]

We could drop color information in deep shadows (not needed) and do geometric approximation instead of arithmetic.

Just an idea......

 

[Roberto Lequeux]

Deanan, Rob, is there any chance of running Graeme's NR on RED Rocket?

 

[Raphael Varandas]

Deanan? Rob?
Graeme's magic please...

 

[Graeme Nattress]

I think they're cracking more important nuts at the moment. Why don't we put that on the "we'll look at it when we have the chance" list.
