Javascript API for premiere pro

Hey Nehru,

As has been explained, there is no "JavaScript API" there is an ExtendScript API for interacting programmatically with Premiere, and the functionality for getting and setting keyframe values within Effect components is demonstrated in the PProPanel sample

Javascript API to change Premiere Pro Lumetri color

Basically, you have to navigate through the active sequence to select the target clip, within the clip to select the target component (eg Lumetri Effect), and within the component to select the target property (eg Exposure etc)

so a particular property (eg Exposure, Contrast, Highlights ect) would be referenced using something like:

myEffectProperty = app.project.activeSequence.videoTracks.clips.components.properties

where 'i' is the target track's index number (within the sequence)

where 'j' is the target clip's index number (within the track)

where 'k' is the component (effect) index number (within the clip)

where 'l' is the property index number (within the effect)

A quick scan of a targetted clip (using code derived directly from the PProPanel sample) reveals the following parameters (properties) for a Lumetri Color effect.

var clipComponents = clip.components; if (clipComponents){       for (var cc = 0; cc < clipComponents.numItems; ++cc) {             $.writeln('component ' + cc + ' = ' + clipComponents[cc].matchName + ' : ' + clipComponents[cc].displayName);             var componentProperties = clipComponents[cc].properties;             for (var cp = 0; cp < componentProperties.numItems; ++cp){                   $.writeln('param ' + cp + ' = ' + componentProperties[cp].displayName);             }       } }
