Red compression and matrix tests

[Muttondraw]

Geoff has posted the final set of images over on Cinematography.net... so that is everything posted.

Too bad the links aren't working.

 

[Muttondraw]

Other images 1, 2 and 3 seem to be linked at the moment, the others aren't yet.

Now I'm excited. It's like xmas!

 

[Justin_Kirch]

Starting to key now. I want that REDCODE image to be linked so I can see how I can key that. Also I want to mess with the color matrix grabs.

 

[Graeme_Nattress]

BTW, I've radically improved REDCODE since those were done

Graeme,

Any chance of giving Geoff Boyle new pictures? I hope the original materal still exists!

Graeme,
Radically is a lot. Tell us more!

 

[Graeme_Nattress]

The material exists, but as REDCODE is in rapid development, I don't see the point of keep posting up every little change I make. I'll be making more changes soon, so let's wait a bit.

And once the architecture is fixed, there's a large bunch of "magic numbers" that can be altered too....

Graeme is such a tease...:laugh:

 

[Graeme_Nattress]

Sure, but that's half the fun isn't it? Don't worry, it's not just you, it's Jim and the rest of the team that I tease too!

Was keying in AE in the 4k film comp settings and I just had to point and click, nothing was a problem. I saw all the detail in the mesh trash can and no color bleeding of the greenscreen. This is awesome!

On the side note and related to the RED's camera: If the matrix is change/modify to allow for more dynamic range, then would the gamma curve be more compressed as a trade-off?

 

[Graeme_Nattress]

We're not changing matrix or gamma curve to get more DR - we're doing some voodoo sensor magic. I think "matrix" was just a turn of speach.

Graeme,
Jim said you made a significant "discovery" today. Care to enlighten us??

Speach?? Is there a fundamental difference between modifying the matrix and doing some 'voodoo sensor magic'?

 

[Brook Willard]

This is fun. It's wretched and took about 4 minutes, but the key is stunning at 4K. One click, one slider and it's clean as hell. A little tweaking and color work [and a background that isn't old, poorly lit and matches] and some amazing stuff could be possible.

I'm so excited. I just threw a second green screen image into the same tree and got the second [coffee] image.

 

[inthemind]

WOW! Brook, that looks great.
I'm so excited to play with this new camera, but I doubt I can light things as nicely as a Pro gaffer.

Thanks for the e-mail help, you've been responsive and knowledgable. Whatever you or the RED's team do to the sensor, DR to me is very important, as I'm doing lots of scene that I have no control of the lighting.
