Try this:

    var myComp = app.project.activeItem;

    if ((myComp != null) && (myComp instanceof CompItem) && (myComp.selectedLayers.length != 0)){

        app.beginUndoGroup("Convert 3D Orientation to Rotation");

        var myLayer;

        var myVal;

        var t;

        for (var i = 0; i < myComp.selectedLayers.length; i++){

            myLayer = app.project.activeItem.selectedLayers[i];

            myOrientation = myLayer.property("Orientation");

            if (myOrientation.numKeys > 0){

                for (var j = 1; j <= myLayer.property("Orientation").numKeys; j++){

                    t = myLayer.property("Orientation").keyTime(j);

                    myLayer.property("xRotation").setValueAtTime(t,myVal[0]);

                    myLayer.property("yRotation").setValueAtTime(t,myVal[1]);

                    myLayer.property("zRotation").setValueAtTime(t,myVal[2]);

                    myLayer.property("orientation").setValueAtKey(j,[0,0,0]);

                }

            }else{

Subject: Re: [AE] Converting animated camera Orientation to Rotation?

 

No... i just want to manually adjust some of the keyframes of the rotation, eg. smoothing some areas, but that is really hard to do with the orientation keyframes when it jumps from 359.9 degrees to 0, making huuuge visual jumps in the graph editor.

Sounds like you want to use an expression rather than a script then?
