Separate the two deliverables at kickoff
The story deliverable has a fixed sequence, chapter boundaries, version history and a continuity burden. The trailer has a conversion job: establish premise, emotion and a next action quickly. They can share footage, but they should not share an assumption that every exciting moment is safe to disclose.
Make one handoff sheet before picture lock. It should name the canonical episode version, approved trailer selects, spoiler tier, music and dialogue rights status, caption/subtitle status, platform owner, aspect ratio, title treatment and links to the current assets. WIPO’s clearance guide is useful general context for treating permissions as a distribution question; it does not confirm clearance for any asset. [World Intellectual Property Organization]
Use a spoiler budget
Label each possible trailer beat: premise, escalation, irreversible turn, answer, ending. The trailer may spend premise and escalation freely. It should spend an irreversible turn only if the episode sequence still has a meaningful earlier question. Answers and endings require an explicit sign-off because they can empty a chapter of its payoff.
The budget creates a useful conversation between marketing and editorial. “It performs” is not enough as a request; identify what story information the clip releases and what the campaign gains in exchange. A trailer can imply danger without displaying the precise evidence that resolves it.
Worked fictional exercise: the wedding video
Original exercise: The episode sequence reveals in Chapter 6 that groom Elias edited his own wedding video to erase a guest. Marketing asks for the reveal because it is visually legible. The handoff sheet labels the unedited frame “answer / no paid social,” but approves an earlier clip of Elias stopping the projector and a reaction from the missing guest’s sister.
The trailer copy asks, “Who was cut from the wedding?” It supplies premise and escalation without using the image that proves the answer. The editor receives the source timecodes and an instruction not to use the subtitle line naming Elias. This is a fictional campaign exercise, not evidence of a release strategy.
QC the campaign as media, not just copy
W3C notes that captions convey speech and meaningful non-speech audio, and that automated captions need accuracy review. [W3C Web Accessibility Initiative] Trailer captions deserve the same attention as episode captions: a wrong name, omitted scream or mistimed line can change the premise. Check title cards and on-screen text separately from dialogue captions.
Final sign-off should compare the exported campaign asset against the canonical story version and the approved spoiler budget. Record what changed after approval, who owns takedown or replacement, and where the current file lives. This does not guarantee platform acceptance or audience response; it makes the creative handoff traceable when either changes.
