Tell me if I'm wrong on any of this:
1. You are knitting continental (German) style.
2. You can see in the video how she gets the "bridge" up onto the left needle.
3. You can't tell what happens after that, that is, how she then actually knits the stitch she's just created with the "bridge".
If all of the above is correct, then this is the answer: she puts the tip of the right needle into the BACK of the stitch (the one created by the bridge, which is now on the left needle). It is hard to see because her hands and the knitting drop to the bottom of the frame of the video picture.
If this isn't helpful and doesn't answer your question, yell!
