Slider

What this is about

The slider exists for the move that would not survive a dolly conversation. Travel is short, so the effect is a slow reveal or a gentle parallax past a foreground object rather than a journey through a room. In exchange it goes up in minutes, needs no track and no extra grip, and fits on a kitchen table or a car bonnet. On narrative sets it is the B-camera and insert tool, and the choice between slider and dolly usually comes down to how many metres the shot needs.

A term only helps when everyone on set means the same thing by it — so what follows is how it is used, not a dictionary definition.

What runs differently here

In planning terms, that means:

• Travel is typically well under two metres, which sets the ceiling on what the move can express.
• On two tripods a slider needs both levelled, or the camera drifts downhill along the rail during the move.
• Motorised versions repeat a move exactly, which matters for time lapse and for VFX plates that must match.

With TillyGen

In TillyGen a slider shot carries a short setup time in the schedule, so small moves stay affordable where a dolly would not fit the day.

Change one constraint and the consequences travel through the whole plan: affected shots are flagged, the call sheet is regenerated, and nobody keeps working from yesterday's version.
