I have the same noise as in the video but not as loud. It happens if I do a restart when the engine is hot and then let it go to idle. Noticed it 10K miles ago but nothing more serious has happened.
The vacuum pump knock on the ATs is well documented. Only remember one guy that had any actual issue with it other than the noise though.
