Broadcast TV Act Breaks: Teaser, Acts, and Tag on the Page

You open a network drama PDF and see words that do not exist in your film school template. TEASER. END OF ACT ONE. TAG. You wonder if the labels are decoration. They are not. On broadcast television, those labels are how the script talks to scheduling, ads, and a room that has been breaking stories in act-shaped chunks since before your favorite streamer had a logo.

Teaser、acts、tag 绝不仅仅是行业传统或惯例，它们本质上是精确的timing modules——时间模块。Teaser 是正式contract of act one 开始之前投放的钩子(hook)，用来在观众还没坐稳时就抓住注意力。Acts 是一个个pressure chambers——压力容器，每一幕都有经过设计的出口(outs)，这些出口必须强到足以survive commercial interruption，让观众在广告插播后依然记得刚才发生了什么、想知道接下来会怎样。Tag 是climax 之后的button——收尾按钮，它提醒观众为什么他们愿意week after week 继续和你笔下的角色生活在一起。流媒体或许在屏幕上移除了广告，但这套page grammar——页面语法依然会出现在coverage、staffing samples、以及那些showrunner 在broadcast clocks 环境中学成出师的编剧室里。

This guide is how to format and write broadcast TV act breaks on the page: where labels go, what each module owes the story, and how to stop treating act breaks as empty white space. When you are building the beat spine that sits under those labels, the pilot beat sheet walkthrough on act breaks that earn their white space is the companion piece. For page bands and module length audits, use the TV pilot page count targets so your footer matches your format.

Broadcast format 本质上是a clock drawn in Courier——一座用Courier 字体绘制的时钟。那些标签告诉制作链条上的每一个人，时钟的指针必须在哪里落下。

What Broadcast Modules Are Actually Doing

The teaser is not always the first scene chronologically—it is the first scene the broadcast night needs: tone, stakes, a question, sometimes a flash-forward that jolts the viewer into attention. It tells the audience what kind of hour they bought, what emotional contract they just entered, and why they should stay through the title sequence.

Acts are story units that end with outs strong enough to survive a commercial break or a streamer's soft pause. An act break is not "we stop because ads need to run." An act break is "we stop because the story just turned," because a reveal landed, because a character made a choice that cannot be unmade, because the dramatic pressure spiked and the audience needs a breath before the next escalation.

The tag is short—often a single scene, rarely more than a page or two. It lands after the climax machinery has resolved, after the episode's central question has been answered. It can be a joke, a sting, a quiet image, a new question that tees up the next hour. It trains the series promise, reminds the viewer why they'll return. Skipping the tag is how pilots feel like closed movies instead of open invitations.

The Module Map Table (Typical Hour Drama)

Module	Typical page span (hour drama pilot)	Format on page	Story obligation
Teaser	2-5 pages	TEASER heading; may be all caps	Hook; question or spike
Act one	10-14 pages	ACT ONE; end with END OF ACT ONE	World, cast, disruption
Act two	10-14 pages	ACT TWO; act out turns obligation	Complication, commitment
Act three	10-14 pages	ACT THREE; midpoint or reversal	Plan breaks, truth shifts
Act four	8-12 pages	ACT FOUR; escalation, cost	Lowest point, forced choice
Act five	8-12 pages	ACT FIVE; climax, pilot resolution	Series question deepens
Tag	1-3 pages	TAG	Button; episode-two bridge

Spans flex by show and year. The obligation column does not flex as easily. If your act three span is fine but the act out is soft, the module failed regardless of page count.

Formatting Labels on the Page (Without Looking Amateur)

Broadcast headings are visible to the reader. TEASER may be centered or left-aligned depending on which competition lane and house style you are matching. ACT ONE appears on its own line. END OF ACT ONE marks the break. Some shows place "END OF ACT ONE" flush to the right margin instead of centered. Match the formatting convention of your specific competition lane and the shows you are targeting.

Do not bury act breaks inside invisible revision comments or hidden formatting layers if the reader expects traditional broadcast structure and pagination. You are not demonstrating sophistication or cleverness. You are forcing coverage readers and script coordinators to work harder to parse structure for no editorial reason, which risks confusion during notes and production prep.

Scene numbering may restart at the top of each act or continue sequentially through the entire script depending on production workflow and studio preference; spec scripts in the broadcast space usually continue numbering sequentially for clarity and readability during coverage. Ask your script coordinator or showrunner if you have one on staff. If you do not have a coordinator, follow the PDF formatting of a sold pilot script in your competition lane as your reference template.

Transitions at act breaks often include explicit "CUT TO BLACK" or a hard cut line to signal the commercial break or streaming chapter division. Do not stack five different fancy transitions in a row or over-format the break. Broadcast script pages favor structural clarity and production readability over stylistic flourish.

For fundamental element formatting before you debate act heading alignment or capitalization, keep your Courier (or Courier Prime) typeface, industry-standard margins (1.5" left, 1" right, and proper dialogue block width), and sluglines honest and consistent. Formatting drift or errors at the act label layer usually means the underlying template or software preset was configured incorrectly from page one, so audit your baseline setup first.

Writing the Teaser as a Module, Not a Short Film

The teaser owes a question or a spike. It does not owe full exposition. If you spend four pages explaining the world before anything moves, you borrowed pages from act one and called it style.

A workable teaser beat sheet line sounds like: "We see the bomb under the table; we do not see who planted it." Or: "The detective laughs at a crime scene; act one will show why that laugh costs her." The teaser should still make sense if act one starts in a different time order, as long as the tone contract holds.

Cold opens that hook without becoming gimmicks are a craft piece of their own. The broadcast teaser is the commercial-era cousin of that problem: you need urgency, not noise.

Act Outs That Survive Interruption

Commercial breaks train audiences to leave. Act outs fight that training. Strong act outs share traits: new information, irreversible choice, reveal, reversal, or a comic button that re-frames the scene you were in.

Weak act outs share different traits: arguments that could pause anywhere without consequence, characters walking down hallways lost in thought, or scenes that trail off with "we'll continue this discussion next act." If the scene could pause for a bathroom break without inflicting story damage—without leaving a question burning or a threat hanging—it is not an act out yet.

Write the act out as a single line in your beat doc, then read all act outs in sequence from act one through act five. Escalation should feel like stairs climbing toward a peak, not a plateau where every act out carries the same weight. A beat sheet builder for TV pilots keeps those act-out lines organized by module while you test the climb and adjust the rhythm.

The Tag: Small Space, Large Job

Tags are short. They are not throwaway. A tag can reframe the climax with new information, introduce a series villain shadow lurking at the edges, land a joke after grief to release tension, or show the world resetting wrong in a way that promises future conflict.

If your tag only repeats the emotional note of act five—triumph after triumph, or melancholy after melancholy—cut it or rewrite it. The tag should add information or promise, shift perspective, or complicate what came before, not echo.

Half-hour broadcast comedy tags often train the "sitcom clock" with a final joke or sting that lands after the credits roll. Hour drama tags might go quiet, holding on a face or a door closing. Match the show you are comping and the format expectations of your target slot.

Relatable Scenario: Labels Without Turns

Morgan formats a network pilot perfectly. TEASER. ACT ONE. END OF ACT ONE. The labels are correct. The act outs are "they keep talking about the case." Coverage says "broadcast shape, soft breaks."

Morgan rewrites act outs only. Act one ends when the witness refuses to testify. Act two ends when the witness is arrested for lying. Act three ends when footage proves the lie was to protect the protagonist's sibling. Same label structure. Different rent. The read upgrades without changing Morgan's voice.

Relatable Scenario: The Movie Pilot With Broadcast Stickers

Tessa writes a cinematic hour. Someone tells her to add TEASER and ACT headings for network submission. She pastes labels without reshaping beats. The result feels like a movie with commercial scars.

Tessa reverses the process. She maps act function first, then assigns modules. The teaser becomes a two-page heist image that act one explains. Act two's out becomes a commitment, not a mood. The tag becomes a quiet beat: the villain's glove left on the protagonist's porch. Labels now describe real pressure, not wallpaper.

Relatable Scenario: Streaming Room, Broadcast Reader

Andre pitches a streamer hour. His sample still uses broadcast labels because the showrunner is broadcast-trained. Andre worries the labels look old-fashioned.

The labels stay in place. The act outs get sharper precision because Andre stops assuming "no ads means no shape." His streamer cut might later remove on-screen breaks during post-production, but the clearly shaped pilot structure gets him the meeting with executives. Andre adds a cover line that reads: "Act-shaped hour; streamer pacing; breaks optional in production." That single sentence prevents the wrong argument about format conventions from derailing the pitch.

Granular Workflow: Mark Modules Before the Draft Sprawls

Outline your script in modules—teaser job, each act's dramatic turn, tag button—not in total page count. Write one sentence for each module to clarify its function.

Assign soft page budgets to each module before writing dialogue. Adjust those allocations after act two is outlined and locked, not after act four has already bloated beyond repair.

Draft the teaser and tag early enough in the process to know your narrative bridges and transitions. If the tag is treated as an afterthought written last, act five will absorb story work the tag should properly handle.

When exporting your final PDF, verify that act break pages align against your beat sheet. Mismatches between promised structure and delivered page breaks erode reader trust and signal lack of control.

Read aloud stopping at each END OF ACT line. Pause five seconds. If the pause feels dead, the out is dead.

Compare to two broadcast pilots in your genre from the last five years. Not from childhood. Mark their teaser length and tag length.

Half-Hour Broadcast: Faster Modules

Half-hours compress everything. Teasers may be one to three pages. Tags are often one page. Joke rhythm carries act outs in comedy. Emotional sting carries act outs in half-hour dramedy.

If you are writing half-hour broadcast, read multi-cam and single-cam format differences before you mark headings. The act labels may look similar while the page band and action grammar differ.

Streaming vs Broadcast on the Same Page

Many streaming hours still use broadcast labels in the spec because rooms think in acts. Production may merge acts. The writer still benefits from act-shaped pressure during drafting.

When a buyer says they do not want act labels, ask whether they mean "no labels on the PDF" or "no act thinking." Those are different requests with distinct implications for script structure. Act thinking is rarely optional for a pilot that must prove serial control and demonstrate command of episodic rhythm.

Coordinators, Coverage, and What They Scan First

Coverage readers often flip PDFs looking for module shape and structural signposts before they read your funniest line or most elegant dialogue turn. TEASER on page one tells them you speak broadcast format fluently. END OF ACT ONE on page fourteen tells them you understand interruption grammar and commercial break architecture. A missing TAG tells them you wrote a closing act without handoff logic, not a pilot built for serialized storytelling.

Script coordinators care about label consistency because production will break your episode into boards for shooting schedules and post-production workflow. If act four heading style differs from act one in font weight or capitalization, you look sloppy before anyone judges story content or character work. Sloppiness is not a moral failure or a creative flaw. It is a time tax on people who have to fix your PDF at midnight when the episode is prepping.

When you revise across multiple drafts, keep act labels stable across drafts even if scene numbers shift due to cuts or additions. Moving headings around to chase pagination or force a cleaner page break tricks readers who compared yesterday's PDF to today's and need to track changes efficiently. Fix dialogue turns and action description inside modules instead of renaming modules or shifting boundaries to hide structural problems.

Comedy vs Drama: Same Labels, Different Act Out Muscles

Broadcast half-hour comedy often ends acts on buttons that deliver a sharp punctuation point. The button might be a line, a look, a physical bit, or a callback that lands clean. Drama ends acts on information reveals or irreversible choice that shifts character trajectory. Dramedy must pick which muscle leads per act—comic release or dramatic stakes—or the tone wobbles and the episode reads confused.

If you write dramedy, mark your act out type in the beat sheet margin: "button" or "sting" or "reveal." When you read act outs in sequence, vary the muscle when possible. Three reveals in a row can work in a thriller hour. Three reveals in a row in a half-hour comedy room can feel like the same note wearing different hats.

Hour-long broadcast comedy exists. The module map still applies. The page band and joke density change. Do not import drama act outs into comedy modules without adjusting the last beat before the break.

Revision Pass That Only Touches Modules

After your voice pass and your dialogue pass, run a module-only pass. Read teaser alone. Read each act as a mini-story. Read tag alone. Do not fix sentences. Only fix missing turns.

If act two's last scene could be cut without changing act three's starting pressure, act two's out is not doing work. If the tag could be deleted and act five still feels complete, the tag is not doing work. This pass is fast and brutal. It saves you from sending a polished draft with unpolished architecture.

When production removes act headings later, you still benefited from the pass because the turns remain in the scenes. Format is the scaffold. Story is the building. Broadcast labels help you build straight before the scaffold comes down.

The Trench Warfare Section: Teaser, Act, and Tag Failures

Wrong: teaser that is only exposition—setup without forward motion. Fix: open with a question the audience wants answered, a tonal spike that unsettles expectation, or a contract that promises what kind of ride this will be.

Wrong: act breaks that are commercial scars without turns—structure inherited from ad pods, not from story pressure. Fix: rewrite the outs themselves so each one pivots tension or reveals a new stake, not just labels where the break falls.

Wrong: missing tag—the episode ends and the story stops cold. Fix: write the button that lands the theme or sets up the next move; train the series muscle so every episode knows how to stick its ending.

Wrong: tag that repeats act five—echoing the climax instead of building past it. Fix: add new information the resolution unlocked, or promise a consequence that will bloom later, so the tag earns its own space.

Wrong: act four bloat to fix act two—stuffing the penultimate act with catch-up because the middle sagged. Fix: strengthen the midpoint so it reframes the question, and make act two carry its obligation to complicate rather than delay.

Wrong: hiding labels to look cinematic. Fix: shape first; production removes later if needed.

Wrong: inconsistent heading style. Fix: pick a comp and match it.

Wrong: END OF ACT lines with no scene turn above them. Fix: move the turn into the last scene beat.

Wrong: treating teaser as act one. Fix: separate jobs; audit pages.

Wrong: page count panic before module audit. Fix: module lengths, then footer.

Broadcast format is not nostalgia. It is readable proof that you can run the clock—that you understand pacing as a structural commitment, not a post-production fix.

Handoff Notes for Coverage and Coordinators

Put module page ranges in your email when you send the PDF. "Teaser pp. 1-3; Act One pp. 4-14; ... Tag pp. 56-57." Coordinators bless you because it shows respect for their workflow. Readers trust you because the structure is already legible before they open the file.

External context helps when you explain why act-shaped specs persist in a streaming-heavy market. <a href="https://www.nab.org/show/become-a-member" rel="nofollow">NAB's industry resources on television production and distribution</a> are a grounded reminder that broadcast infrastructure still shapes how many shows are made even when your sample targets a streamer interface.

Teaser, acts, and tag on the page are how you show you understand the hour as machinery—not as a loose assembly of scenes. Labels are not decoration. Act outs are not optional. The tag is not frosting. Write the modules with turns, format them with clean headings, and let white space mean something happened: a beat landed, a question opened, momentum shifted.
