The missing option…

[Jeremy Garchow]

Bring it.

Sent him about R3D option.

Hope it works 🙂

SLog2 and S-Gamut would be nice as well!

I wonder what the performance is like. Usually LUT filters are fairly atrocious.

The top item in the list of LUTs was “External File.”

Wasn’t it playing in real-time on the video? Scaled video, sure, but still promising.

OK, so what exactly is LUT? I know it’s Look up table but is it a LOOK that is applied instantly to the clip but can’t tweak it or what is it? Is it like using MB’s Quick Looks or something?

I saw that, and those are the ones that usually don’t perform as well.

Mmm, kind of clever editing there.

As you said, a LUT is a look-up table. LUTs describe a fixed transformation from one color space to another. For each pixel in the image, you look up the value of the input in the table and set it to the corresponding output value.

LUTs are not traditionally used for creative looks, but rather for technical color transforms — like moving from a specific camera’s acquisition color space to a display space like Rec. 709.

In what context? It shouldn’t make a difference.

LUTs can be easily GPU-accelerated [link].

Thanks for info – wondered.

But for whatever reason it does, at least with FCP7.

Take Glue Tools. Glue Tools allows a sweet Color and Gamma transform from LogC to Rec709.

It plays in mostly real time.

But Lut Buddy, is slow. Sure, there’s giant price point between free and Glue Tools, but you see what I’m saying. All filters are not created equal, and LUTs aren’t always simple drag and drop operations.

Sure, they can be GPU accelerated, but this is Apple we are talking about here.
