serves the editor... (try to make the editors job easier)
As a composer, I can't really speak for editors. But if their job is like anyone else's on the planet, they want to work more efficiently. They want to get their job done better and quicker so they can move on to the next job.
At Dig It, we are always thinking about the cut.
FORMATTING
On our long-form trailer work, (especially the Fantasy & Adventure series; F&A I, F&A II, F&A III, F&A IV) the cues have an extra intro with an interesting stop. After that, the cue has an introductory section, the 1st Act, that sets the scene and stays at this level for a while with maybe a slight build into the section that builds tension; the 2nd Act. We like to provide material to make a complete change so in a lot of cues there are a couple of sections built at this level. But before we get to the 3rd Act, we like to provide another "wild card," section. This is just another groove for a change of scene, most likely cut out or used as an extra transition to or from one of the acts. The 3rd Act may just be a rising tension that builds to an end in a short time to cut to the big cue. Or it may have a full blown drive that goes to the end of the trailer.

The short-form trailer work is a little different. In these cues, we are just trying to set a tone and provide structure for cutting. Most trailers, especially action, need a cadence. A big part of the library are these kind of cues where structure is king; big hits and pauses, sound design or musical textures broken by ticking, pulsing and building tension. Expect these cues to set a tone with a deeply interesting stereo field that provides momentum towards an edit with a hybrid combo of music, sFx, sound design and percussion.
