Typical timelines: 6–12 weeks for a studio trailer through a trailer house, 2–4 weeks for a scrappy independent cut, days for an AI-assisted pass on existing or generated material. The cut itself is a fraction of the calendar; approvals, music licensing, finishing, and versioning consume the rest.
Producers asking how long a trailer takes are usually asking a different question: why does something two minutes long need a quarter of a year? The answer is that a trailer is not an edit. It’s an edit wrapped in a negotiation wrapped in a licensing process wrapped in a finishing pipeline — and each wrapper has its own clock.
The traditional calendar
Weeks 1–2: ingest and concept. The trailer house watches everything — cut footage, dailies, script if the film isn’t finished — and pitches concepts: the structure, the tone, the music direction. Weeks 2–6: the cut. Editors build, the studio notes, editors rebuild. Three to six rounds is normal; double digits is not rare. Weeks 4–8, in parallel: music. The track everyone loved in the cutting room turns out to cost six figures or be unclearable, and the hunt for its legal twin begins — routinely the single longest pole in the schedule. Weeks 6–10: finishing. Conform, grade, mix, graphics, MPA rating card, deliverables. Weeks 8–12: versioning. TV :30s, social verticals, international texted/textless — the teaser/trailer family tree multiplied across every aspect ratio a platform demands.
Independents compress this to two to four weeks mostly by having fewer approvers and braver music taste. The mechanics don’t change; the meeting count does.
Where the time actually hides
Notice what the calendar is made of. The creative cut — the part everyone pictures — is perhaps a third of it. The rest is waiting shaped like process: approval layers, license negotiations, finishing queues, versioning matrices. Any honest acceleration strategy attacks the waiting, not the cutting.
What AI compresses — and what it doesn’t
An AI production layer attacks the calendar at three points. Material: when the film isn’t finished — or doesn’t exist yet — the missing shots can be generated to spec instead of waiting on production: establishers, inserts, world shots, the connective tissue trailers are starved for. Iteration: alternate structures stop costing a week each; three different trailers can compete for the same slot in the time one rough cut used to take. Versioning: reframing and reconforming across deliverable specs collapses from a week of conform work to a pass. What it doesn’t compress: taste, approvals, and music law. A studio’s seven layers of sign-off and a publisher’s licensing desk run at the speed of institutions, not inference. The realistic AI-era schedule for a marketing-grade trailer with cleared music: two to three weeks, of which the cut is days.
Planning numbers to keep
Working backward from a release date: lock the trailer brief 12 weeks out for a traditional pipeline, 4–6 weeks out for an AI-assisted one. Budget the music search from day one — it’s the schedule’s true boss fight. And if the campaign needs a teaser first, see our cost breakdown and start it earlier than feels reasonable; teasers forgive nothing.
