Ride the authored move like a dolly grip.

A flight is an authored camera move, with a planned route, framing and pace from departure through landing. Some moments do not keep to a plan. A baptism runs long, a speaker walks into the aisle, an encore arrives that nobody scheduled. Jog is the hand on the move: take a stick or a wheel and ride the prepared flight forward or backward, quick or slow, for as long as the moment lasts.

The camera stays on the route you composed the whole time. A stick cannot steer the shot off that route, so the person riding it supplies timing and nothing else. Every frame on the way is a frame somebody already approved, in daylight, at a desk.

That is what makes it safe to hand to a volunteer. There is no framing to find under pressure, no way to end up somewhere nobody would cut to, and no need for the one person who can drive a joystick smoothly to be in the building. Let go, and the shot is where the production expects it.

The same hand works on every prepared move, so a team learns one habit and applies it everywhere. The judgement stays in the composed move; the timing stays with the person watching the room.

Jog works from the controller your team already has. A VISCA joystick panel on the desk, or a USB joystick or gamepad plugged into the computer, can ride the move, and both run today. The same stick axis does the same job on every flight.

Use a cue when the moment keeps to plan and jog when it does not. Either way the camera stays on a route somebody composed, so the choice is about timing and never about where the shot goes.
