If the car isn't throwing any codes I wouldn't worry about it to be honest. The engine does make some additional noises upon startup. My understanding is it's something out of the fuel purge (fumes) system.
The only one to be concerned about is a worn timing chain, but that one sounds like metallic rattling, which I don't hear in your video.
