Rattle after start in engine bay?

I've noticed an audible rattle or noise right after the engine starts.
I used remote start for this video, do you guys have this rattle/noise when starting the engine?
It sounds like dice shaking in your hand

Yeah. A bit of clatter until something related to cam drive/valve hardware receives sufficient oil pressure.

Unless the noise persists nothing to worry about.

Thanks for the reply! When you say persists, you mean after the engine has started?
Or do you mean if this noise happens for months/years at startup?
I have a feeling this brief noise isn't going away

A bit of clatter at cold start is normal. But it should be very short lived.

If after engine start if the noise persists that can be a warning sign of a problem.

Over the years I have heard various noises from start that persist. One time the noise -- a low rumble sound -- was a bad water pump.

Another time a dry bearing sound was a bad accessory drive system idler roller bearing.

Then a hard to describe noise but a new noise proved to be a radiator fan motor which had suffered from a snapped shaft. The motor was happily spinning but without the spinning the radiator fan.

And one more: An intermittent chirp was yet another failed idler roller bearing.

But I have to stress I'm not a professional auto tech.

The noise bothers you. Be sure you can reproduce the noise and have the car and have a tech give a listen. If the tech says not a problem there you go.
