Bolt Cam

An industrial robot arm throws the camera along a path faster than any operator could, and holds it perfectly steady the whole way. The result is speed with no human error in it.

That combination does not occur in nature, which is why it reads as expensive. The audience sees violent motion and a frame that never wavers.

It also removes the sense of a person choosing. Nothing hesitates and nothing corrects, so the shot feels authored by the product rather than observed by a crew.

The arm is programmed rather than driven, so the path is exact and repeatable. It can accelerate hard, stop dead, and change direction in a way a dolly cannot.

The steadiness is the signature. There is no wobble at the ends of the move, no settle, and no operator correction anywhere in it.

It suits tight, curved paths around an object. Around a bottle, under a car, through the gap in a set, at a speed that makes the subject look immovable.

The move is often shot fast and played faster, or shot slow and sped up. Either way the final speed is decided after the take, which is part of why the path has to be exact.

Use it for product films, car commercials, food, and titles where the camera should look superhuman.

Skip it for anything meant to feel observed. The move announces a budget and a rig, so it cannot be invisible.

It also tends to be short. Two or three seconds is a whole bolt cam shot, because the move is the content and there is nothing to develop.

A crash zoom in changes the focal length in place, so nothing travels and every plane stays locked together. A bolt cam physically covers ground at speed, so the parallax is enormous.

Look at the background through the move. Sliding and separating planes mean the camera travelled. A flat, uniform rush toward the centre means the lens did it.

Models add shake to sell the speed, which destroys the look. Ban shake, drift and wobble, and ask for a dead steady frame through the whole move.

The second failure is a slow, smooth move with no violence in it. Name the acceleration and the hard stop, because the speed is half the shot.

A third problem is a path with no object to pass. The speed only reads against something close, so put the camera near a surface at some point in the move.

A fourth problem is a frame that never gets close. The arm exists to pass near things at speed, so give it a surface, an edge or a gap to travel past.
