Dear JesusFish,
Instead of following the character, use an angle inside the room, in the hallway, and outside. Cameras following a character is difficult and can only be done with real movies. An example would be 0:15 - 0:17. Notice that instead of following the jeep, the camera is stationed in an area at a certain angle. Please apply this tip into your videos next time.
Sincerely, Wing Zero.
