Filming - Alana moving around

Last week Alana and I took the cameras after school and did some filming by her house, we found a street lamp that she could stand under and then took a 4 second clip, we then moved her but didn't move the camera so it looked like she was moving. We played back all the footage and it looks really creepy. We also filmed Alana outside some garages and did the same thing again where the camera doesn't move but she did, we moved her in front of all the garages and then again played the footage back and it looks really creepy, I think if we have this flashing on and off really quickly on screen then we can scare our audience.
