Create an AI Explainer Video

Quick answer

To create an AI explainer video without filming, define one audience question, write a short narration, assign one visible job to every sentence, generate or record the audio, create the visuals, assemble the scenes, correct the captions, and verify every claim and interface step before publishing.

AI can replace the camera step. It does not replace the decisions that make an explanation accurate, easy to follow and useful.

Choose the right no-camera format

  • Screen recording: best when the viewer must click, configure or verify something in software.

  • Diagram or motion graphic: best for systems, processes, numbers and ideas that cannot be filmed directly.

  • Generated scenes: best for concepts, environments and illustrative examples that do not need to reproduce a real interface.

  • Avatar or talking photo: best when a visible narrator adds orientation or continuity. Use an approved identity and label synthetic media where required.

  • Hybrid: combine screen capture, diagrams, generated b-roll and a short presenter segment when each has a clear job.

1. Write the explainer brief

  • Audience: who is watching and what do they already know?

  • Question: what single problem will this video answer?

  • Outcome: what should the viewer understand or do afterward?

  • Proof: what demo, source, calculation or result will show the explanation is correct?

  • Next action: what is the one relevant step after the video?

If the brief contains several unrelated questions, split it into separate videos.

2. Write narration that can be shown

Use this order: answer → why it matters → essential steps or mechanism → proof → next action. Keep each sentence short enough to pair with one clear visual. Replace vague claims such as “faster” or “better” with the exact behavior, measurement or limitation you can demonstrate.

Read the script aloud before generating anything. Fix names, numbers, transitions and pronunciation in the copy rather than trying to hide them with visuals.

3. Turn the script into a shot list

For every sentence, write four fields: narration, visual job, source or asset, and approval condition. Example: “Select Export” → close screen recording of the real Export control → current product build → reviewer confirms the label and result match the published interface.

Use the AI storyboard generator for a visual draft when helpful, then replace generic frames with the exact product, diagram or evidence the explanation requires.

4. Create and approve the voice track

Record a narrator when the speaker’s identity or expertise matters. Use text to speech when a synthetic voice is appropriate and permitted. Generate in sections so a pronunciation or claim correction does not require replacing the full track.

  • Pronunciation: check names, acronyms, numbers, URLs and product terms.

  • Pacing: leave room for the viewer to inspect each visual and complete multi-step actions.

  • Consistency: preserve voice, volume and tone between regenerated sections.

  • Rights: use only voices and source audio you are allowed to use.

5. Create visuals for the explanation

  • Real interface: record the current product when the viewer must follow exact controls. Generated UI can misteach the workflow.

  • Conceptual scene: use the AI video generator for illustrative shots whose purpose and limitations are clear.

  • Visible narrator: use a talking photo for a short approved presenter segment, then inspect lip sync and identity.

  • Diagram: label the elements and animate only the relationship the narration is explaining.

  • Evidence: show the actual output, source, calculation or before-and-after state rather than decorative b-roll.

6. Assemble one idea per scene

Place each visual at the moment its idea is spoken. Remove shots that repeat the narration without adding evidence or orientation. In the AI video editor or another timeline, check the sequence once with sound, once muted for visual comprehension, and once audio-only for narration clarity.

7. Add and correct captions

Generate a draft with the subtitle generator, then proofread it against the approved script. Correct names, technical terms, punctuation, numbers and speaker changes. Keep captions clear of interface controls, disclosure labels and other required text.

8. Run a factual and visual review

  • Accuracy: every claim, number, price, policy and interface step matches the cited current source.

  • Comprehension: a reviewer from the target audience can state the answer and complete the next action.

  • Continuity: terminology, styling, speaker, audio level and visual conventions remain consistent.

  • Synthetic artifacts: inspect hands, faces, text, logos, geometry, cuts and temporal consistency.

  • Rights and disclosure: confirm input rights, approved identities, commercial-use terms and destination labels.

  • Versioning: store the script, sources, assets and publish date so changed facts or product UI can be replaced later.

A compact 60-second explainer template

  • Opening: “[Answer]. Here is the shortest way to understand or do it.”

  • Context: name the constraint or decision that makes the answer matter.

  • Steps: show two to four essential actions or parts.

  • Proof: demonstrate the result or cite the authoritative source.

  • Close: state the limitation and one next action.

Treat 60 seconds as a production constraint for this template, not a universal optimum. Use the duration needed to complete the promised explanation clearly.

A red ceramic mug sits on a wooden café table beside a window. Steam rises slowly while the camera makes a gentle push-in. Soft morning light, realistic materials, one continuous shot, no people or readable text.

Create the first explainer scene

Start with one approved scene: one sentence of narration, one visual job, and one measurable result. Build the remaining explainer only after the scene is clear and accurate.

Frequently asked questions

Yes. Use screen recordings, diagrams, generated visuals, narration, captions or an approved avatar. Choose each format by what the viewer needs to see.

Approve the script first, then create the voice track and time visuals to it. For a product demo, capture the current workflow before writing narration that names exact controls.

Long enough to answer the promised question and verify the result. Remove unrelated context and repeated visuals rather than forcing every topic into a fixed duration.

Specific claims, current sources, real demonstrations, legible graphics, corrected captions, consistent audio and an explicit boundary between evidence and illustration.
