I have 2014 Toyota Corolla LE 1.8L CVT, with 74,500 miles and the oil light flashes briefly on startup beyond the normal idiot light check. I found footage from about a year ago, but just noticed this recently. This happens on startup, cold or hot, and it comes BACK ON after the idiot-light-system-check thing is finished. Have had oil changed since then, no alteration. The engine makes no strange noises.
Worth noting this engine has always revved up to 2,000 RPM briefly when starting, especially cold, then immediately drops to 1,000 RPM, where it holds for a few minutes until the engine warms up and idles at the normal 700 RPM. As far as I can tell, the oil light flash tends to correspond with that initial rev-up, but that may be splitting hairs. Car runs perfectly fine. I'm in Texas, if that's relevant.
The light does NOT flash back on if I stop the car and start it again. If the car sits for even a few minutes, and I start it, it does so. It can't be more than half a second. Sometimes it just doesn't happen at all for whatever reason, but it happens more than it doesn't.
Footage below shows it not happening, then it happening:

Oil light is located in the left pod right above the check engine light. The car always beeps a ton on startup, that's just the seatbelt warning, so that's not part of it. Forgive the briefness of the footage, it was a camera test. Thanks for any help!
I don’t think there’s any issues (the light came on for less than a second). Unless the light comes back on for longer or your hearing any weird sounds should be fine. If anything maybe it’s a sensor or something. I would hook up a pressure gauge (at least temporarily) and see if you notice anything weird (whenever the light is acting up).
