I made an object and created a 'path' around it using the line. Then, going to Animation- Constrains- Path constrains I clicked to the path and the object appeared on it. I went to the time line Frame 50- Auto key and selected Follow. I changed the number so the object go fast and then slowly.

Then, I created a box in the middle of the path and created a camera ( Create-Cameras). I went to Animation- Constrain- Path constrain and clicked on the camera so it appeared on the road. Changing the direction it started to move around the object and 'film' it.
