Average shot length
Also known as: ASL, mean shot length
The running time of an edit divided by its number of cuts, a single number that describes how fast a finished sequence feels to watch.

What it means
Divide the duration by the cut count and one figure comes out. It says nothing about any individual shot and a great deal about the whole piece. Nothing else summarises an edit so compactly.
Action edits live low. A Supercut of landings runs under a second per shot, while a surf film that wants to breathe sits several times higher. The same material supports both, which is the point worth remembering.
It is a description rather than a target. Two sequences with identical figures can feel completely different depending on where the long shots sit. The average hides the shape.
How it works in practice
The useful version is per section. An opening at one rate, a middle that accelerates and an ending that holds gives a Story arc something to climb, and a flat average hides exactly that.
Music sets the floor. Cutting faster than the Beat grid allows produces shots that land between accents, which reads as sloppy rather than as energetic. The grid is a floor, not a suggestion.
Platform matters too. A YouTube Shorts audience tolerates a far lower figure than a long edit does. Total Edit length and the average pull in opposite directions, and both are chosen per destination.
What to watch out for
Chasing a low number produces incoherence. Shots cut before a viewer has read them leave an impression of speed and no memory of what happened. Recognition takes longer than attention does.
Long averages have the opposite failure. Dead time inside shots is what pushes the figure up, and trimming the dead frames usually improves the edit and the number together. The cause and the symptom are the same frames.
The figure also distorts when one long shot dominates. An uninterrupted two-minute run raises the average while the rest of the sequence is cut rapidly, and no single rate describes it.
How RawClip handles it
Pacing is decided while the sequence is assembled, with cut density following the music and the strength of each moment rather than a fixed figure. Sections tend to come out faster where the action is dense and slower around the shots that establish a place.
