Build-up
Also known as: riser, tension section
The section of a track that increases tension before a release, which an edit can use to accelerate towards its best moment.

What it means
A build-up is the stretch of music that climbs. Instruments are added, filters open, drums tighten, and the arrangement leans forward towards something that has not happened yet.
It is the half of the structure that makes a release work. A Beat drop with nothing before it is merely loud, while one preceded by sixteen bars of building is an event.
For editing it is a window with a direction. The footage placed there should get faster and more intense rather than merely being good, because the music is already telling the viewer where this is going.
How it works in practice
Shot lengths shorten through the section. Starting with three or four beats per shot and ending on one produces acceleration a viewer feels without noticing the mechanism.
The build is also the right place for approach shots. A rider climbing, a drone rising, a hand on a throttle all carry anticipation and would be dull anywhere else, which makes them ideal filler for a Story arc that needs a run up.
Matching the first cut of the build to a bar boundary matters more than matching the rest, because that is where the viewer notices the change of gear in the Beat grid.
What to watch out for
Filling a build with the strongest footage wastes both. The best moment arrives before the music has finished promising it, and the release then has nothing left to land on.
Builds also tempt over cutting. Shortening shots too aggressively produces a stretch where nothing is on screen long enough to read, which reads as panic rather than tension.
A build with no release at all is the worst outcome. If the track was trimmed before its drop, the edit accelerates towards silence, and no amount of Audio fade work disguises it.
How RawClip handles it
Approach shots and rising action are placed in the building section of the track and shortened as it climbs, so the strongest moment arrives exactly when the music releases. The track is never trimmed in a way that removes the release the edit was built towards, which is the single most common way an automatic cut to music falls flat.
