Is this the window regulator?

So put the driver's window down to get at the mailbox. Went to put the window back up and it only made it halfway when it jammed (I think) and started making this noise (in the video).


Took off the panel expecting to see broken clips in the rails, but they look okay. I could "help" the window go up with my hand and it would operate normally. Now, after taking the video to record the sound, there is no attempted movement of the window. You can hear the motor click with the switch operation, but that's all it does. (Edit: 1/2 hour later when I tried it again and gave it some more "help", it did do the same as the video shows and I was able to get the window all the way closed.)

Is something just jammed, are the gear teeth ground off (then why wouldn't the motor still run?), or is the whole regulator just shot? Anyone run into this kind of noise before? Winter is coming, I need the window to close!
