This one has lots of negative comments. So maybe the video in combination with the comments might be helpful.

Hey Jim,
I'm not impressed with that video. Guy is putting too much heat on the tube. You should put 95% of the flame on the lug and the heat will spread to the tube. Finished shots of the lugs show his feed points. Messy. It's okay to feed and pull the filler into the joint but this one just doesn't look right.
