One Intent, Three Aspect Ratios: Board Once for Reel, Feed, and Deck
Board one teach intent for 9:16, 1:1, and 16:9 with a shared beat spine plus per-ratio crop and title rules—no three rewrites.
One Intent, Three Aspect Ratios: Board Once for Reel, Feed, and Deck
Plan one teach intent across 9:16, 1:1, and 16:9 with a shared beat spine—then add per-ratio crop and title rules instead of writing three separate scripts.
Marketers and agencies burning cycles on triple rewrites usually change the wrong layer: the intent. Freeze the teach claim and the beat order first; only framing, title safe-zones, and end cards should flex. This builds on choosing 9:16 vs 16:9 vs 1:1 before you lock the storyboard—here the goal is one master board that fans out cleanly.
What stays frozen vs what must change
| Layer | Freeze across ratios | Adapt per ratio |
|---|---|---|
| Teach intent / claim | Yes | No |
| Beat order and jobs | Yes | No |
| Proof facts / UI version | Yes | Crop tighter or wider |
| Hook promise words | Yes (same meaning) | Line breaks / size |
| Host framing | Character lock | Headroom / side room |
| Captions | Same text spine | Safe-zone placement |
| End card / CTA | Same ask | Layout density |
If the 16:9 deck version teaches a different claim than the Reel, you no longer have one campaign—you have three. Intent drift is how "multi-format" becomes three unpaid scripts.
Shared beat spine (master board)
Write the master as ratio-agnostic beats:
- Hook — promise the outcome in one line
- Problem — specific failure
- Mechanism — transferable step
- Proof — UI or metaphor evidence
- Soft CTA — next step
Example spine for "export last month's PDF from Billing":
| Beat | Claim words (frozen) |
|---|---|
| Hook | "Month-end PDF without spreadsheet export" |
| Problem | "CSV dump → broken formulas" |
| Mechanism | "Billing → Export → Last month PDF" |
| Proof | Cropped export dialog + dated file |
| CTA | "Save the export path" |
Approve this spine once. Ratio notes attach underneath; they do not rewrite the spine. Weekly batches still benefit from one approved style lock.
Master-board fields worth freezing
- Intent one-liner
- Audience assumption (who already knows what)
- UI version date for proof crops
- Host / character ID
- Words that must appear on screen (claim spine)
- Words that must never appear (overclaims)
Everything else is presentation.
Per-ratio crop and title rules
9:16 (Reel / Stories)
- Subject in center third; UI crops favor vertical stacks
- Titles ≤2 short lines in upper safe zone
- Captions avoid bottom UI chrome and platform buttons
- Host: medium shot; leave chin-to-bottom breathing room
- Prefer single-column proof; avoid side-by-side that becomes postage stamps
1:1 (Feed)
- Prefer centered subject; avoid ultra-wide UI that needs pan
- Titles can sit as a top banner card
- Proof UI: square crop of the control cluster, not the whole app chrome
- CTA cards can sit center-bottom without fighting Stories chrome as hard
16:9 (Deck / LinkedIn / YouTube)
- Side-by-side allowed: host or card left, UI right
- Titles can be fuller (still one claim)
- Do not invent extra beats just because you have width—pad with proof, not new claims
- Useful for webinar cut-downs; see also from one webinar to a week of vertical explainers when the source is long-form
| Element | 9:16 | 1:1 | 16:9 |
|---|---|---|---|
| Title lines | 1–2 | 1–2 | 1–3 |
| UI crop | Tall cluster | Square cluster | Wide or split |
| Host | Center | Center | Left or PiP |
| CTA | Bottom card | Center card | Right/end slide |
First-frame rules still apply on every ratio; see thumbnail and cover frames that match the hook beat.
Workflow: master → notes → three renders
- Approve master spine (intent + beats + claim words)
- Attach crop boxes and title placements for each ratio on each beat
- Generate or shoot stills for the riskiest beats (usually hook + proof) in all three crops
- Stakeholder sign-off on stills, not on finished videos
- Render per ratio; if one ratio fails QA, regenerate that ratio only
This is the opposite of "render 9:16, then stretch." Stretching is how illegible chrome ships on LinkedIn.
Anti-patterns
- Rewriting VO for each ratio while keeping the same messy crop notes
- Three different hooks that promise three outcomes
- Stretching 9:16 into 16:9 without re-cropping UI
- Adding deck-only "agenda" beats that never appear in the Reel (intent drift)
- Separate style locks per ratio without a reason (visual brand muddle)
Filled multi-surface package example
Intent: "Invite with Viewer role, not Admin."
Master spine (frozen):
| Beat | Claim words |
|---|---|
| Hook | "Viewer invite ≠ Admin invite" |
| Problem | "Everyone gets Admin → audit mess" |
| Mechanism | "Invite → Role → Viewer" |
| Proof | Cropped role picker + confirmation |
| CTA | "Screenshot your invite path" |
Ratio notes (abbreviated):
| Beat | 9:16 | 1:1 | 16:9 |
|---|---|---|---|
| Hook | Center host + 2-line title | Banner title | Split: title left, still right |
| Proof | Tall crop of role list | Square around Viewer | Wide dialog + pointer |
| CTA | Bottom card | Center card | End slide |
Same intent. Three crops. Zero rewrite of the teach claim.
Naming and delivery
Use filenames that encode ratio without renaming chaos:
invites-viewer__master-board.jsoninvites-viewer__9x16_v1.mp4invites-viewer__1x1_v1.mp4invites-viewer__16x9_v1.mp4
Captions file can be shared (invites-viewer__captions.srt) if timing matches; if proof crops change timing, maintain per-ratio caption pulls from the same text spine.
Stakeholder one-liner
"Same teach. Three crops. One approval of the spine." Put that sentence at the top of the review invite so executives do not ask for a new script per channel.
Soft close
Approve one master board, then ratio-specific frame notes, before any render. Storyboard-first tools like Scro make that master-plus-notes workflow concrete for multi-surface teach campaigns.
