PR Scripting QE .getItemAt() not working properly

Question

I am using the getVideoTrackAt and getItemAt methods to apply an effect to a clip. However it is only working when using the first clip on any given track. Also, the indices required seem to not be working, unless I am missing something simple. The videoTrack I am storing is working fine, but when I try to get any other item besides the first, it gives me undefined. Here is my simple project setup and code:  app.enableQE();
var clip; 
var thisTrack = qe.project.getActiveSequence().getVideoTrackAt(1);

clip = thisTrack.getItemAt(0);
// gives me undefined

clip = thisTrack.getItemAt(1);
// gives me the first clip in the track

clip = thisTrack.getItemAt(2);
// gives me undefined

Thanks for your help @Bruce Bullis ! The issue was that I was confusing the vanilla and qe ways of looping through items. With the normal way of looping through all the clips in a video track, it only counts the visible clips, but with the QE way, you must also take into account the 'empty clips' between any present imported clips!

QE example of looping through each item (0->numItems-1)

This will get you the second video track in the sequence; the first would be at getVideoTrackAt(0).

The success (or not) of the getItemAt() calls, will depend on what's in that track.
