Is your AC on? I get that when my AC is on for some reason. Along with RPM dropping.

After reading this my guess is a blown motor mount.

But wouldn't that happen every time I turn the car on? I seem to only get it to make the noise when it's been off overnight, and cold.

Also, wouldn't I feel it while driving? It runs like butter besides that one noise. I'll try to get a video today.

Yes it would, my bad. Although my old corolla drove pretty good when a mount was bad, it shook on every start up.
