Direct Answer
The short answer
An explainer should be written around one audience change: what the viewer should understand, believe, compare, or do after watching. The script controls message and timing; the storyboard controls visual meaning; the animatic tests whether voice, text, images, and transitions work together before full animation begins.
Evidence boundary: The public motion-graphics portfolio verifies finished visual output. This guide describes a production method and does not claim a specific script, campaign result, or client approval history for linked work.

- When should voice, music, captions, and localization be planned?
Practical Takeaways
What to decide before production
- Write for one viewer and one next decision.
- Assign one visual job to each section.
- Read the script aloud before approval.
- Use the storyboard to verify meaning, not decoration.
- Approve an animatic before full animation and final audio.
Begin with the audience gap
A useful brief states what the audience knows now, what they misunderstand, and what should become clear. That gap is more actionable than a request to make an exciting explainer.
Choose one primary viewer. Secondary audiences can still benefit, but the script should not switch unpredictably between an engineer, a customer, an investor, and a new employee.
Build a message hierarchy
Separate the essential statement, supporting points, proof, context, and optional detail. The viewer should understand the core idea even if a short edit removes supporting sections.
Every number, comparison, product statement, and promised result should come from an approved source. A script can make evidence easier to follow; it cannot manufacture evidence.
Write for speech and time
A script that reads well on a page may sound dense when spoken. Read it aloud, time it, remove repeated setup, and leave space for the viewer to inspect important visuals.
On-screen text should reinforce the message rather than duplicate every spoken word. If the piece will play silently, create a deliberate sound-off version instead of assuming captions alone solve visual pacing.
Storyboard visual meaning
Each frame should explain what the viewer sees and why it supports the line. Useful visual strategies include product demonstration, diagram, comparison, sequence, hierarchy, transformation, data relationship, or restrained metaphor.
Avoid filling every second with unrelated motion. Movement should guide attention, establish cause and effect, or support the transition to the next idea.
Use the animatic as a comprehension test
The animatic combines storyboard frames, rough motion, temporary narration, labels, and approximate transitions. Reviewers can evaluate whether the audience has enough time, whether a graphic appears before it is explained, and whether the ending earns the call to action.
Changes here are much cheaper than changes after illustration, 3D, simulation, voice, and compositing are final. Approval should cover sequence and pace, not only visual taste.
Plan audio, accessibility, and versions early
Voice talent, pronunciation, music, sound design, captions, audio description, localization, platform crop, and runtime affect the structure. Identify these needs before final animation.
Deliverables should state which files include narration, music, captions, clean picture, alternate language, square or vertical framing, and thumbnail art. Confirm the relevant licenses and usage terms.
Decision Table
Plan the decision before production
| Artifact | Question it answers | Approval focus |
|---|---|---|
| Message brief | Who needs to understand what? | Audience, objective, evidence, action |
| Script | What is said and in what order? | Meaning, claims, tone, runtime |
| Storyboard | What does the viewer see? | Visual logic, hierarchy, feasibility |
| Animatic | Does the sequence work over time? | Pace, comprehension, transitions |
| Style frame | What will the finished piece look like? | Brand, typography, material, color |
| Final edit | Is every approved asset usable? | Picture, sound, captions, versions |

FAQ
Questions buyers ask about this topic
How long should an explainer video be?
Long enough to complete one communication job without unnecessary setup. Audience, placement, complexity, viewing context, and available evidence matter more than a universal runtime.
Should the script or storyboard come first?
A message outline and working script usually lead, but visual thinking should influence revisions. Do not lock language that cannot be explained clearly in the available screen time.
Can an explainer work without narration?
Yes. The piece can use visual sequence, concise labels, captions, and sound design, but sound-off comprehension must be tested deliberately.
Who should approve the script?
Assign owners for factual accuracy, claims, brand voice, accessibility, and the final communication decision. One project owner should consolidate their feedback.
