Need Link

Anyone have a good link to a knot passing video?

I assume you mean for toproping.
With an ATC, you cram the rope above the knot into the second hole of the ACT when the knot gets to the device of the first hole. If the climber is in a good stance that helps so they don't fall while doing this. You will need a foot or so of slack to do this.
Or if you have a third person to take the rope above the knot and put it into the their belay device and they take over from there until the climber is lowered. Then you switch back to the original belayer when you get to that part of the rope.
It is an advanced belay technique. Be careful
Sorry no video footage for you.
Good luck on those long routes.

If you're on toprope, there is usually no need to pass a knot.

If you're doing some emergency rap, then *sorry no video* but this Supertopo thread has rgold's recommendation at the bottom of the first page and Chongo's method on the second.

Hope that helps.

It occurred to me that you were talking about Rappelling.Sorry.
Just go to You tube.There are a bunch out there. This is the link to the page and there is like at least ten.I'm not sayin this video will deliver the best info. It was just the longest.
Seek an experienced teacher for this. A climbing class or something.
Practice on the ground to be safe also.

Thanks guys. I figured it out. DOINK. (DOINK is my sound for feeling stupid).
