Aloha,

What does the "color" button at the top left of Redcine do? It seems like this button turns off all the color settings in Redcine and shows what you really have. So far most of the footage I have played with looks best with this turned off. Can you output footage like this?

Dusty
 
Reset all seems to put me back to the camera settings.

With color turned off, I get a good waveform with all the data.

I am looking at the Silverado footage. Some of the footage is over exposed and clipping. If I turn off Color, all of a sudden I have no clipping and plenty of data above and below on the waveform.

Dusty
 
Turning 'Color' off gives you a 'Linear Light' image. This is everything that was captured on the sensor without a gamma correction applied.

Is this correct Graeme?
 
Color Off does not give a linear light image. It gives a no matrix and basic gamma curve decode. I'd suggest that if you see no clipping there, but that there is when it's on, that you drop the "exposure" at least 0.4EV and set ISO to 320.

Graeme, I was looking at the same footage and to me it is overexposed. But, if I remove the color correction I see an image I can't seem to recreate and it would be interesting to be able to start there as now with the color button removed--no color changes have any affect.

I did set the ISO to 320 and changed the exposure to -.4 but it didn't come close to the detail I was looking at with color off.

What is the best way to adjust the color to retrieve that hidden detail?

I sure would like to see an ungraded still and a perfectly graded still with a snapshot of what was done in RedCine to grade it.

Best Regards,

Thom
 
Well, you've removed white balance and colour space, and there's no REC709 (or redlog or...) gamma curve, just a very basic one.

If you have a more extreme white balance correction you may need to knock it back more than 0.4EV to see it all.

Graeme,

Since I noticed this I have checked all the footage I have and Color Off would be really great as an optional starting point. I can not recreate the look of Color off by changing every setting in Redcine.


Thanks,
Dusty
 
Set custom gamma to 1.0. Set Exposure to -0.4EV. Set Kelvin to 6502. Set tint to -2.3. Set Saturation to 0.94. And that's as close as I can get for now.

Graeme
 
They will give the same result as color off, or as close as I can quickly and easily get. There's still a subtle shift in saturation, but it's close enough that if you like that look you can grade from it.

Graeme
 
Just curious.

Which would be the best setting in RC for later grading, if one assumes that footage is exposed well with 320 ASA and a 10Bit codec is used?

Do you recommend REDlog as gamma, exposure set to 320 ASA and additionally -0.40 EV applied?

Hans
 
That would make sense for a 10bit DPX output.

Graeme
 
All depends on what you want to do with it. REC709 is nearly as good in terms of data precision.

Dusty,

That's what you get when you race up Hwy. 50, shoot three locations in Tahoe, and race back down in less than six hours.
