You should share projects, not videos. All I can do with a video is watch it, shrug, and say that shouldn't happen.
It's a common mistake, so without any further evidence I can only assume it is a mistake in your project and it is doing something framerate-dependent by accident. You can still make behaviors work framerate dependently if you create incorrect events, like setting a speed to 500 * dt, which basically breaks it, since it makes a framerate-independent value become framerate-dependent.
