There's no function for adding (or removing) tracks, in the PPro ExtendScript DOM.
Perhaps you could create a new sequence from a template?
Hey Bruce,
thanks for your reply 🙂
The problem was, that using the remove functions with QEDom was causing an audioTrack to be deleted, which was not empty.
I am not really sure why this happened, but after cleaning up my code a little the problem did not seem to occur anymore.
In this case, I am sending commands to AfterEffects via BridgeTalk, because I thought we do not need an extra AE-panel for the usecase.
This works pretty neat, but I forgot some simple things, like "do not import footage if

Is there a way to get a specific sequence with the qe dom rather than just the active sequence?
This might help when trying to find a sequence by id:
var removeEmptyAudioAndVideoTracksInVersionSequence = function removeEmptyAudioAndVideoTracksInVersionSequence(sequenceId) {
app.enableQE();
var bin = getBinFromQEDomByPath('mybin/sequences');
if (bin) {
bin.flushCache();
for (var index = 0; index < bin.numSequences; index++) {
sequence = bin.getSequenceAt(index);
if (sequence && sequence.guid === sequenceId) {
sequence.removeEmptyAudioTracks();
sequence.removeEmptyVideoTracks();
return 'true';
}
}
}
return 'error: bin not found!';
};
var getBinFromQEDomByPath = function getBinFromQEDomByPath(binPath) {
app.enableQE();
var qeProject = qe.project;
// remove last char if it is a slash
binPath = binPath.replace(/\/$/, '');
var binPathAsArray = binPath.split('/');
// start at root level
var bin = qeProject;
// go as deep as the binPath is
for (var binNameIndex = 0; binNameIndex < binPathAsArray.length; binNameIndex++) {
for (var currentBinIndex = 0; currentBinIndex < bin.numBins; currentBinIndex++) {
var binToFind = bin.getBinAt(currentBinIndex);
if (binToFind.name === binPathAsArray[binNameIndex]) {
// return it because it is the last bin of the path from binPath
if (binNameIndex === binPathAsArray.length - 1) {
return binToFind;
}
// it was the next bin of the path from binPath
bin = binToFind;
// stop inner loop, continue with outer loop...
break;
}
}
}
// not found
return null;
};
I still have a sporadic problem, that sometimes audioTracks are removed by ``removeEmptyAudioTracks()`` which are not empty 😞
Can anyone confirm this?
(at least in Windows, PPRO 2019 - did not test with other versions yet...)
