A storyboard turns an explainer video script into a sequence of planned visual moments. Think of it as a comic-strip production plan: each panel shows what viewers will see while the narration, dialogue, or sound plays.

The storyboard connects the script to production by telling an animator, filmmaker, editor, or designer what to create and when it should appear. It also specifies how the scene should move and which details matter. You do not need polished drawing skills. Rough sketches, screenshots, arrows, simple shapes, and reference images work when they clearly communicate the intended scene. Adobe’s storyboard guidance treats the board as a planning document rather than finished artwork.

A reliable workflow is:

Brief → script → storyboard → animatic or review → production

An animatic is a timed slideshow of storyboard panels with temporary narration, music, transitions, or motion. It helps you judge pacing before investing in animation or filming.

Start with one message

Before you draw, decide what the video must accomplish. Write a one-sentence brief using this structure:

For [audience], this video will explain [topic or problem] so viewers understand [single takeaway] and then [desired action].

For example:

For new remote managers, this video will explain how a shared task board prevents handoff mistakes so they will try the weekly planning template.

This sentence keeps the video focused on one goal. A short explainer cannot fully cover a product’s history, every feature, and every benefit. Choose the one problem the viewer recognizes and the one next step you want them to take.

Finish and time the narration

For an explainer led by narration, write the script before you create detailed panels. The narration sets the order of ideas, the length of each explanation, and the visuals needed to support it.

Read the script aloud and record how long it takes. The National Center for Voice and Speech gives about 150 words per minute as an average speaking rate for U.S. English speakers, so that figure provides a rough starting point. Pauses, emphasis, screen demonstrations, captions, and unfamiliar concepts require additional time. A real read-through gives you a better estimate than word count alone.

Mark each meaningful change in the script. A beat is one small unit of meaning or action, such as introducing a problem, showing a new screen, explaining a cause, or demonstrating a step.

Create a new panel when the viewer needs to see something materially different. The Government of Canada’s video guidance also recommends dividing scenes when the location, subject, or camera placement changes.

Give every panel one clear job

Each panel should answer one question:

What exactly is the viewer looking at while this line is spoken?

Useful explainer visuals include a character facing a problem, a before-and-after comparison, a simplified product screen, a process diagram, or a close-up of an action. Choose the visual that helps viewers understand the spoken point.

A visual that does not explain, compare, demonstrate, or emphasize anything is decoration. Research summarized in The Cambridge Handbook of Multimedia Learning supports removing irrelevant material and using cues such as highlights, labels, and arrows to direct attention.

Keep early drawings rough. A stick figure can show a character’s position and action. A rectangle can represent a video player or interface. Arrows can show movement. Add detail only when it changes the production decision.

Record the details a producer needs

You can keep the storyboard in a spreadsheet, slide deck, or document. The format matters less than the information in each panel.

Field What to record
Panel number A precise reference for feedback
Time range When the panel appears and disappears
Narration and audio Exact voiceover, music, or sound-effect cues
Visual Sketch, screenshot, reference image, or UI mockup
On-screen text Labels, key phrases, data, or call to action
Movement Character action, screen interaction, reveal, or transition
Camera Close-up, wide view, pan, zoom, cut, or screen recording
Assets and rights Source link, stock ID, owner, or original-asset note
Accessibility Caption, description, contrast, or readable-text requirements
Status Draft, revised, or approved

The Adobe production tutorial recommends connecting visuals, audio, text, notes, and production information. NASA’s storyboard worksheet also includes media sources and credits, which helps prevent asset problems later.

Use precise instructions. “Make this engaging” does not tell a producer what to build. “Zoom into the task card, highlight the due-date field, then reveal the notification” does.

Plan accessibility during storyboarding

Plan accessibility in the board because it affects composition, narration, and editing. W3C guidance recommends planning accessibility during scripting and storyboarding.

Check that:

  • Captions and a transcript are planned.
  • The narration communicates information that would otherwise exist only in a chart, label, or visual action.
  • On-screen text remains readable against its background.
  • Instructions do not rely only on color, position, or appearance.
  • Important content will not sit beneath a possible sign-language overlay.
  • Flashing effects are reviewed against the limit of more than three flashes in one second.
  • Background music will not compete with speech.

Captions should remain in the plan even when large blocks of repeated text would distract from the visuals. Learning research warns against unnecessary duplication, while captions provide access to spoken words and meaningful non-speech audio. Use concise emphasis text for labels, key terms, and calls to action rather than displaying the entire narration as decorative copy.

Review the board before production

Read the narration aloud while moving through the panels. Look for rushed explanations, missing visual steps, and panels that remain unchanged for too long.

Then review the board with the sound off. Without narration, can someone follow the basic sequence of problem, solution, demonstration, and outcome? The answer does not need to be complete, but the visual logic should be visible.

Finally, give the board to someone unfamiliar with the project. Ask what they think each panel shows and what needs to be created. Misunderstandings at this stage cost less to fix than misunderstandings during animation or filming.

Create an animatic when motion or pacing remains uncertain. It is especially useful for strict runtimes, complex screen demonstrations, frequent transitions, or stakeholders who struggle to imagine movement from still images. Adobe’s animation guidance describes animatics as rough animated versions of storyboards that can include audio and transitions.

Common mistakes to avoid

Most problems start before you draw:

  • Starting detailed panels before the narration is stable
  • Packing several unrelated ideas into one panel
  • Prioritizing polished artwork over clear instructions
  • Omitting timing, movement, transitions, or asset sources
  • Using visuals that merely repeat the narration
  • Leaving captions and visual descriptions until the final edit
  • Approving the board without testing it against the voiceover

A useful rule is simple: rough image, precise instruction.
