A practical library of vertical video prompts, episodic outlines, and microdrama character arcs for data-driven creator workflows.

Hook: Stop gambling on one-off prompts — build a reusable library for vertical-first series

Creators and publishers in 2026 face a familiar but costly problem: scattered, inconsistent prompts that produce hit-or-miss concepts for short-form vertical video. You need predictable ideation that maps to attention metrics, discovery algorithms, and rapid iteration. This article delivers a practical, production-ready library of vertical video prompts, episodic outlines, short-form scripts, and character-arc templates optimized for microdrama, Holywater-style platforms, and algorithmic discovery.

The context in 2026: why vertical-first AI ideation matters now

By late 2025 and into 2026 the streaming landscape pivoted fast: mobile-first platforms (Holywater among them) closed funding rounds and announced scaling plans focused on serialized microdrama and algorithmic IP discovery. Creators aren’t just making standalone TikToks — they’re building episodic franchises for vertical feeds. Meanwhile, improvements in multimodal LLMs and cheap analytics pipelines let teams optimize content against real-time discovery signals.

“Holywater is positioning itself as ‘the Netflix’ of vertical streaming,” — industry reporting on Holywater's Jan 2026 funding round.

That combination—publisher-grade distribution + AI ideation + data feedback—makes a reusable prompt library essential for teams who want reliable concept-to-pilot pipelines.

What you’ll get in this blueprint

Ready-to-use prompt templates for series ideation, episode breakdowns, and microdrama short-form scripts
Character arc and beat-sheet templates tuned for 15–90 second vertical episodes
Data-driven prompt patterns to integrate performance signals into ideation
Versioning, governance, and workflow tips to scale prompts across teams and APIs

Core principles for vertical-first AI ideation

Before prompts, codify the constraints and signals your platform values. Use these as fixed inputs to every prompt so outputs are consistent and measurable.

Hook-first storytelling: The opening 1–3 seconds must promise conflict or curiosity.
Beat economy: Fewer beats, clearer stakes—design for 15/30/60/90-second runtime profiles.
Discovery signals: Include algorithmic goals like completion rate, early watch-through, and rewatch potential.
Data-in loop: Seed prompts with trending tags, audience cohorts, and keywords from analytics exports.
Reusability: Author prompts with modular slots for genre, tone, and CTA so teams can A/B quickly.

How to structure a production-ready prompt

Use a 5-part pattern for every prompt. This enforces clarity and versionability.

Intent: One-line goal — e.g., "Create 8-episode microdrama concept optimized for 30s episodes."
Constraints: Runtime, style, platform, and required tags (e.g., #microdrama #relationship).
Inputs: Audience cohort, trending keywords, seed analytics (JSON/CSV excerpt).
Output format: Clear structure: title, logline, episode beats, key hook, CTA, export metadata.
Evaluation metrics: Suggested A/B test variables and measurement KPIs.

Template 1 — Series Ideation Prompt (Vertical, 8–12 episodes)

Use this as your baseline series generator for pitch-ready concepts.

Intent: Generate an 8-episode vertical-first microdrama series optimized for 30s episodes and high early watch-through.

Constraints:
- Runtime per episode: 25–35 seconds
- Tone: tense but empathetic
- Target platform: vertical streaming / mobile-first
- Include 3 searchable tags and 2 hook variants

Inputs:
- Audience: 18–34, urban, loves short-form romance/mystery
- Trending keywords: ["neighbor mystery", "secret note", "urban soprano"]
- Performance goals: completion rate >= 65% first 7 days

Output format (JSON):
{
 "title": "",
 "one_line": "",
 "series_logline": "",
 "tags": [],
 "episode_breakdown": [
   {"ep":1, "hook": "", "beat1":"", "beat2":"", "cliff":""}
 ],
 "character_arcs": [ {"name":"","throughline":""} ],
 "hook_variants": ["",""],
 "test_variants": [{"variable":"thumbnail","options":[]}, {"variable":"endcard","options":[]}]
}

Evaluation: Suggest A/B variables: thumbnail, hook line, music bed intensity.

Example output (short)

Run the prompt and expect a titled concept, a tight logline, tags, an 8-episode micro-beat sheet, and 2 hook variants ready for thumbnail/CTA tests.

Template 2 — Episode Outline for 15–60s Microdrama

Episode outlines for short-form need to be ultra-specific. Use this beat-sheet for each episode.

Intent: Create a 30s episode outline for episode {n} in series {title}.

Constraints:
- Total run: 28–32 seconds
- Visual direction: close-ups, single-location, minimal set changes
- Dialogue budget: 4 lines max

Output structure:
- Timestamped beats (0–5s: Hook; 5–15s: Complication; 15–24s: Escalation; 24–30s: Mini-cliff)
- Camera note per beat (e.g., "tight over-the-shoulder")
- Subtitle text (short) and suggested SFX/Music cue
- CTA/endcard note (1–3 words)

Example:
0-3s Hook: POV close-up of protagonist reading a folded note; subtitle: "It says: don't answer." SFX: paper rustle
3-12s Complication: Protagonist debates; neighbor knocks; cutaway to suspicious text message
12-20s Escalation: She opens door; reveals unexpected face; music swell
20-30s Mini-cliff: Door closes; camera lingers on note now on the floor; endcard: "Find out why"

Template 3 — Short-Form Script (Dialogue + Stage)

Convert the outline into a 30–60s script with clear shot directions and subtitle-ready dialog.

Intent: Render stage directions and subtitles for a 30s vertical microdrama episode.

Format:
- Shot 1 (0-4s): INT. APARTMENT - TIGHT - Morning
  Action: [ALEX] reads a folded note. Close-up. Subtitle: "Don't come back."
- Shot 2 (4-12s): Tight two-shot - Alex and neighbor
  Dialogue: NEIGHBOR: "You okay?" Subtitle: "You okay?"
- Shot 3 (12-22s): Insert - Phone buzz; text preview: "We saw you." Music: low synth
- Shot 4 (22-30s): Close-up - Alex drops the note, camera lingers
  Endcard: "Episode 1/8 — Tonight"

Notes: Keep audio ducked under dialog; use hard cuts; avoid exposition longer than 3 lines total.

Template 4 — Character Arc Microtemplate (3-episode arc)

Short arcs must accelerate—use a three-episode micro-arc template for mini-payoffs that keep viewers returning.

Intent: Define a 3-episode arc for a supporting character to create an emotional bite.

Structure:
- Episode A (seed): Reveal a secret habit or motive (hook)
- Episode B (escalate): Secret impacts main conflict, small personal choice shows change
- Episode C (payoff & twist): The character's choice recontextualizes past scenes; leave a question for future episodes

Deliverables:
- Name, core desire, blindspot, inciting detail, 3-episode micro-arc summary (one line per episode)
- Suggested single-shot visual motif (e.g., "cigarette lighter click")

Example: Holywater-style pitch using the templates

Below is a condensed example you can copy into your prompt manager or prompt SaaS to generate pitch decks and episode files programmatically.

Intent: Create an 8-episode vertical microdrama titled "Quiet Floors" for 30s episodes.
Constraints: See Template 1.
Inputs: Audience 18-34, trending: ["apartment drama","missing note"], KPI: completion >= 65%

Output: JSON with title, logline, 8 episode outlines, 3 character arcs, 2 hook variants, thumbnail copy.

Data-driven ideation: feeding analytics back into prompts

By 2026, the advantage is not just generating ideas but coupling them with performance signals. Here’s how to operationalize data-driven ideation:

Export sample analytics: Pull top-performing video metadata (title, tags, retention curves) weekly as CSV/JSON.
Seed the prompt: Include the top 5 performing tags and the retention shape (e.g., "high drop at 3s, spike at 20s").
Prompt directive: Ask the model to prioritize hooks that address the 3s drop and to design a 20–25s escalation to match the spike.
Automate iterations: Use an API workflow that re-runs ideation prompts after 7 days and compares predicted vs actual CTR/completion.

Data-seed snippet (JSON)

{
 "top_tags": ["microdrama","neighbor mystery","romance"],
 "retention_pattern": {"drop_at_s":3, "spike_at_s":20},
 "audience_cohort": "GenZ-urban",
 "recent_keywords": ["secret note","stairwell","siren"]
}

Prompt instruction: "Use the above data to create 3 hook-first loglines prioritized to mitigate the 3s drop and exploit the 20s spike."

Testing matrix: what to A/B and why

Short-form performance gains come from rapid, narrow tests. Prioritize:

Thumbnail + Text Tag: 20%+ variance in impressions to watch-through. Use a small studio setup or tiny-studio shooting checklist for consistent thumbnail composition.
First 3 seconds: Two hook variants (question vs action) — directly impacts drop at 3s.
Music intensity: Low vs. high bed to test emotional engagement spike at 20s.
Endcard CTA: Follow vs. next-episode tease — measures retention across episodes.

As prompt libraries scale across teams, use these operational rules to avoid entropy.

Semantic naming: Use prefix conventions: series.idea/v1, episode.outline/v2, arc.supporting/v1.
Change logs: Store the prompt, the output snapshot, and the performance summary together. Keep immutable outputs for audits and follow the guidance in governance playbooks.
Access control: Writers get edit rights; data engineers get parameter inputs; legal sees tags and IP notes.
Template hygiene: Have a review pipeline every 2 weeks to retire outdated constraints (platform APIs and feed rules change fast in 2026). For lightweight tool audits, see how to audit your tool stack in one day.

Security & IP notes for creator prompts

Prompt reuse makes IP questions urgent. Protect your prompt library and the value encoded in it.

Internal prompt registry: Centralize prompts in a private repo with access logs.
Attribution metadata: Tag prompts with origin, author, and paid model used (some outputs may be restricted by model TOS).
Content ownership: For commercial use, include a line in your prompt workflow that enforces original-author checks and flags near-duplicate outputs.

Operational workflow: from ideation to episode asset (fast lane)

Run Series Ideation prompt -> select top 3 concepts
For chosen concept, generate 8 episode outlines -> prioritize first 3 for pilot
Convert outlines to short-form scripts -> generate visual shot list + subtitles
Render test cuts (use micro apps or quick-edit templates) -> run A/B on thumbnail/hook
Collect analytics -> feed back into Ideation prompt weekly

Case study (brief): Fast pilot loop for a microdrama brand

In late 2025 a mid-size publisher used a prompt library and automated data seeding to launch a three-concept pilot slate. They produced 24 episodes (8 per concept), ran two A/B tests per episode, and within 6 weeks identified one concept with a sustained completion rate increase from 48% to 71% after iterating hooks and endcards. The secret: consistent prompt constraints and tight test matrices that targeted the 3–6 second drop point.

Advanced strategies: multimodal prompts & micro apps

2026 tools let you supply images, audio snippets, and short clips as inputs. Use multimodal prompts to tune cinematic language and thumbnail composition. Pair ideation prompts with micro apps (vibe-coded workflows) to auto-generate test edits for TestFlight or private feeds.

Supply a thumbnail image + retention pattern to generate three hook copy variants matched to visual cues.
Feed a 5-second loop of the intended music bed and ask the model to recommend cut points for beats.
Integrate with low-code micro apps to push rendered drafts directly to private test channels for rapid feedback. For strategies around edge visual authoring and observability, see edge visual authoring.
