whats the logic for changing track matt key effect values for Matte: how to set the track index , as it is not straight up entering track index!! i tried entering multiple index but the index is not representing the track and also it is not changing sometime

 

var clip = app.project.activeSequence.videoTracks[0].clips[0];
var effect;
for (var i = 0; i < clip.components.length; i++) {
    var component = clip.components[i];
    if (component.displayName == "Track Matte Key") {
        effect = component;
    }
}
if (component) {
    var prop = effect.properties[0];
    prop.setValue(5);
    var prop = effect.properties[1];
    prop.setValue(2);
}

    also if  someone is not able to change the values for the "Matt:" property and looking for a solution check that your main sequence track names are not changed , that is :- like you manually renamed the track names in such cases also the value will not change even if you rename the track name back  to normal (not in my case"didnt tryed restart after rename method") , a workaround  way is to copy all the clips and paste in a new sequence and not to forget to use the "updateUI" param ......

    Please provide a .prproj, and a snippet of ExtendScript, that make the problem plain. [Send to me directly, if you like.]

    I notice you're not passing the second "updateUI" param to setValue; that can't be helping. 🙂

    Also if you are using qe dom to add video  tracks then such video tracks are named incorectly and wont be recognised as a correct track index  by the api and will be hard to debug this slight overlook .....
