Is this a brake or engine issue?

This issue occurred 3 times over 2 months. I am on the brakes at a stop light and the car will suddenly jump. The car doesn't move but it feels like if u accidentally lift off the brakes and immediately step on the brakes.

I initially thought this might be a brake problem but could it be an engine issue with it jumping? I am on OEM brakes and rotors. The system says I need new brakes in 10k miles.

Another completely different issue that might be related? I drove off about maybe 1000 yards to a stop sign and the car was randomly reving with my foot on the brakes. I assume it's just the cold start but this was a one off experience.
