Cam break in check list

You need at least 2 people, one to maintain rpm's and one to monitor the engine.

You may also want a fan to put in front of the radiator blowing air into it, or at least have one set up handy if needed.

Double check all connections, electrical hoses etc.

Before starting check and double check all fluids, prime. Get it running and smooth it out as quickly as possible.

And yes by all means video.
