Noisy blacks

What???
Scarlet also has low compression,
as in, low as 3:1 just like the EPIC-X.

???

Can only get as low as 6:1 on Scarlet at 24fps in 4K.
I suppose if you wanted to shoot less fps you could get down to 3:1.

Well it seems most users agree that 800 ISO is the best to shoot at, even outside.

So when you guys are shooting with daylight balanced LED's, what are you doing to combat the green spike? I know most sill use minus green filters, but that didnt really seem to help all that much. I have never seen my Rosco LED's look so green before on any other camera.

I really do appreciate all the opinions and feedback. This is just one of the many reasons why I chose RED.

Great thread. So this is effectively a bump to keep it rolling.

+ 1 on the Gunleik book btw.

If they are daylight balanced, they shouldn't have a green spike, right? i have a couple 6500 K lights (prototypes) and use a minus green to get them down to 5600 and they look right at that temp. The final versions, they got down to 6500 by more precisely binning the LEDs.

Like fluorescence, LEDs are a discontinuous spectrum light source - which means they do not output the entire visible spectrum of light and have spikes in certain wavelengths (green being one of them). This green spike is more prominent with the RED camera system. I am not sure why, but it is something about the image sensor that makes some LEDs (and my LitePads) look even greener than they actually are.

Ahhh, yes. I forgot.

However, 6:1 is not so bad.

TGWDT was at 5:1, and lots of other major features.

[Evin Grant]

We haven't seen much diffference in noise character till 10:1 and even then nothing bad till 12:1. I tend to shoot at 6:1 on the Epic simply because it gives me the record time I'm comfortable with on the 128GB SSDs.

[Florian Stadler]

If you look at the blue channel only you can see an appreciable difference in noise characteristics between 5:1 and 8:1. I'm sure 6:1 is a solid size/benefit compromise...

Gunleik,

When are you going to write a book?

Hm... LOL!!!!

When it's commishioned and I can ask for articles from those I would like to have with me, maybe... But I guess really: Never.

Which would mean that I would ask for articles by Graeme, Michael Most, Gary Adcock, Michael Cioni, David Mullen, Nick Shaw as a start, in addition to myself.

If I should write a book, I think I would prefer the general theme being Digital Cinema, and Digital cinema cameras in TV productions, rather than a RED specific theme.

BUT with specified subchapters for the most relevant cameras, being (methinks)
The RED lineup, Arris cameras, C300, and Sony F65/F3

I would not spend time on the DSLRs, except maybe for a small chapter explaining the differnce between digital cinema cameras, and the DSLRs...

So...

But seriously:

Currently trying to de-geekify myself a bit and get back to mainly shooting and directing.
That's where it started and is at for me, really...

Artiocles and tests take so muuch time and focus away from what it is really all about.

Good to have that knowledge when you shoot, though...


LOL

Gunleik, great article!!!
So what is your recipe on shooting with MX? Do you prefer 320 or 800 both in 3200 and 5600 enviroment? Do you advice to use 80C on lens? Please, share your best practice.
Thanks,
Alex
