Javascript API to change Premiere Pro Lumetri color

[nehrus86783659]

Is there any Javascript API available to change the Premier Pro Lumetri Color programatically.

While not JavaScript, PPro's ExtendScript API can be used to manipulate effect parameters, including Lumetri.

Hi Bruce Bullis​,

Thank you for your comment on the above topic. Please let me know the link to the Extended script API to change the Premiere pro Lumetri programatically.

Thanks,

Check the PProPanel sample Nehru,  it demonstrates how to get/set keyframes.

Andymees,

I cannot able to see any javascript API related to Premiere Pro Lumetri color change. Please let me know where I can find a link to javascript API to change the Lumetri parameters like (Exposure, Contrast, Highlights, Shadows, Whites, Blacks and Saturation etc.)

Thanks

Nehru

You can access the details of most parameter types, for effects.

Looking for an update on this question.  Wasn't able to get any clues to an answer from the links above.

Are there ways to view & control Lumetri parameters using ExtendScript?

Following up: one of the above links has since gone dead, and didn’t see clues in the one that works.

Any Lumetri options in the API?

Yes; This link works.

Thanks Bruce,

That link cues to the onPlayWithKeyframes method and gets into manipulating Gaussian blurs.

Didn't see anything specific to Lumetri and a word search of entire page for "Color" and "Lumetri" didn't reveal anything relevant?

Is the clue, by chance, in the clipComponents array?  The AE.ADBE Lumetri : Lumetri Color

What I'm looking for is a way to get programmatic control over RGB and Hue/Saturation curves.

Is that possible?

[Bruce Bullis]

The parameters for any effect are components. Apply some instances of Lumetri, then fiddle with the components.

Have vacation -- will fiddle.  Thanks

Sadly, I may also be a scripting nerd, in my off-hours.

Hey. I have created a bit of documentation on the accessing Premiere's effects (and properties of the effects), if you are still interested.

Premiere Pro / Extendscript API Effect Component Reference Book

It doesn't help you with how to change each property, but at least points you in the right direction when compared with the "onPlayWithKeyframes" example. This way you don't have to search through to find the correct property index.
