The documentation for apply LUT effect is pretty limited.
I was wondering if there were any AE compatible LUTs available for download I might be able to use for color grading.

[jim bachalo] "I was wondering if there were any AE compatible LUTs available for download I might be able to use for color grading."

LUTs are usually used to communicate color grades from one system to another (for example, a colorist could send a LUT to a compositor).

Some systems use LUTs for color management, but the After Effects color management system is built around ICC profiles -- a far more flexible and elegant system, in my opinion.

What exactly is it that you want to do with LUTs?

Was under the impression that you could use LUTs for color curve presets, to save certain looks.

There are certain looks I am trying to match using curves but having a difficult time.

[jim bachalo] "Was under the impression that you could use LUTs for color curve presets, to save certain looks."

You absolutely can -- with the proviso that a LUT is limited to translating one table of colors directly to another -- but I don't know of anyone sharing LUTs online as artistic presets. (Of course, that doesn't necessarily mean they're not out there.)

Again, though, I think LUTs are mainly used as technical, system-specific tools for working with particular cameras, displays, or film stocks.

If you want to save a LUT from AE, check out Red Giant Software's free LUT Buddy [link].


[jim bachalo] "There are certain looks I am trying to match using curves but having a difficult time."

Curves may not be the best tool for the job -- can you post some stills showing the look you're going for, and the footage you're working with? Maybe we can help.

Thanks Walter.
LOTS of looks I'd like to be able to match using only curves.

Here are 3 that spring to mind!

1-old Kodachrome from Library of Congress (I tried all the film presets in Color Finesse but none come even close)

here's 1 favorite

besides the obvious crushed blacks, not sure how to best approach this using curves.

love the look of a few of these Canon picture style presets
here's 2 I really like

I'm pretty sure its possible to approximate these looks using RGB curves only, but I could be wrong.
Perhaps in conjunction with another effect or setting in Color Finesse?

Why limit yourself to Curves in Color Finesse? I think the HSL controls are quite a bit more approachable for manipulating hue, and the CMY controls might be worth looking into for emulating older film stocks.

I think that these looks will be next to impossible to achieve with primary color correction alone -- secondaries will make this a lot easier.

You could set up a preset for the look you want.

Now, the problem comes if the underlying footage varies. This (old) tutorial [link] may help.
