Video 1: The official has a much better angle than the camera. There are two options from what I can see.

1. The defender leaned into the path as the dribbler was about to go around him.
2. The official holds to the myth that a player must be "set" to draw a charge.

I'd say the odds of both are about 50/50 given the video I'm watching.

Video 2.
The dribbler is barely phased by this, so it's generally a good no-call. From the camera angle, I can't even tell if contact is made. If there's no contact, there's no foul. If there's contact, but the dribbler isn't affected, there's no foul.
