# AI Explainer Video Generator

> An AI explainer video generator turns a topic or a script into a short video that explains one idea, product or process, with visuals, a narrator, captions and music. On Kenerate AI, Director's Explainer Quick Start drafts the script and shot plan, renders each shot, voices the narration with ElevenLabs and exports one MP4 that you caption in Auto Subtitles — a 60-second explainer starts at about 1,000 credits on Wan 3.0 at 480p. Director and Video Studio need a paid plan; a talking-presenter explainer in Avatar Talk works on credits alone.

## Steps
1. Open the Explainer Quick Start — In Director, choose Explainer and say what you want to explain and who it's for. Pick a look (Minimal, Whiteboard, Illustrated or Cinematic), a length (30–180 s) and 16:9, 9:16 or 1:1. Add up to 4 diagrams, screenshots or brand images.
2. Check the script — Director drafts a hook, the idea in one sentence, 3–5 points and a recap — about 150 words for 60 seconds. Read it and fix any fact, name or number before the shots render.
3. Approve the shot plan — Every point gets its own visual or title card. Pick the shot model: Wan 3.0 for value, Seedance 2.0 for richer motion. Render, look, and redo only the shots that miss.
4. Pick the narrator and music — The narrator is an ElevenLabs voice (Eleven v3 or Multilingual v2); the music bed is Ken Music, ducked under the voice automatically.
5. Export, then add captions — Export one MP4 at 480p, 720p or 1080p (15 credits per started minute). The export has no captions: press Subtitles on it to open Auto Subtitles, pick one of 10 styles and burn them in — 20 credits per started minute at 720p, 40 at 1080p, for videos up to 4 minutes.
6. No paid plan? Use a presenter — Voice the script in Voice Studio, give it a face in Avatar Talk (Kenerate Avatar, 7.5 credits a second at 720p) and add captions with Auto Subtitles.

### What is an AI explainer video?
An explainer video is a short video that makes one thing clear: what a product does, how a process works, why an idea matters. The classic shape is a hook, the idea in one sentence, three to five points, and a recap — narrated, with a simple visual for each point and captions underneath.
An AI explainer video generator does the production work: it drafts the script, makes the visuals, voices the narration, adds music and captions and assembles the video. You still own the substance — the facts, the order of the points and the final check.

### What's automated, and what isn't
Honest split for Kenerate's Director:
- Automated: the script draft, the shot plan, each shot's render, the ElevenLabs narration placed per shot, the Ken Music bed (ducked under the narrator) and the final MP4. Captions are not in the export — Auto Subtitles adds them in one more pass.
- Yours: the topic and audience, checking every fact and number, approving or redoing shots, choosing the narrator voice and pressing Export.
- Not included: screen recording of your own software — add real screenshots as references (up to 4) or record your screen separately.

### Product, how-to and training explainers
The same tool, three different jobs:
- Product explainer: 60–90 seconds, one problem and how the product solves it; Minimal or Cinematic look; end with one call to action.
- How-to: one task in numbered steps; Whiteboard or Illustrated look; on-screen text for each step.
- Training: 2–4 minutes, calm narration, captioned in Auto Subtitles (4 minutes per video at most); split longer courses into one video per topic so updates stay cheap.

### Captions aren't optional for training
W3C's WCAG 2.2 success criterion 1.2.2 asks for captions on all prerecorded audio in synchronized media — which covers almost every narrated explainer [2]. Many people also watch with the sound off. Director's export has no captions, so run it through Auto Subtitles — one pass for videos up to 4 minutes, the same as for any other video.
On YouTube, AI-written scripts, auto-generated captions and cloning your own voice for a voice-over are listed as not needing a synthetic-content label; realistic scenes that didn't happen, or real people appearing to say things they didn't, do [1].

### What other AI explainer tools offer
From each vendor's own page, read on 22 October 2026 [3][4]:
- HeyGen: start from a script, PDF, slides, URL or prompt; an avatar presenter or animated scenes; 300+ voices; synced captions; HD or 4K MP4. It suggests 60–90 seconds for marketing and 3–5 minutes for training; the page lists no prices or maximum length.
- invideo AI: pick an actor, describe the video, then edit the script, music, voice-over and subtitles; 50+ languages and a large stock library. No length, price or watermark details on the page.
- Kenerate: a credit price before every render, four explainer looks, ElevenLabs narration, burned-in captions through Auto Subtitles (up to 4 minutes per video), up to 10 minutes per film, no watermark — and a presenter route that works without a paid plan.

### Explainer briefs and prompts to copy
The first three are briefs for Director's Explainer Quick Start; the next is a title card for Image Studio; the last is a 60-second narration script for Voice Studio.
- 1. Product explainer (Director brief): A 60-second explainer about how our invoicing app sends automatic payment reminders, for freelancers who hate chasing clients. Cover: why late payments happen, how reminders are scheduled, what the client sees. Friendly, clear narration. Minimal look, 16:9.
- 2. How-to explainer (Director brief): A 90-second how-to on setting up two-factor authentication on any account, for non-technical adults. Cover: what 2FA is in one sentence, choosing an authenticator app, scanning the code, saving backup codes. Calm narration. Whiteboard look, 16:9.
- 3. Training explainer (Director brief): A 2-minute training explainer on the three fire exits on our office floor, for new staff. Cover: where each exit is, the assembly point, what not to take with you. Calm, steady narration. Illustrated look, 16:9.
- 4. Title card (Image Studio, GPT Image 2.5 Sunburst): A clean 16:9 title card on an off-white background with the words "How 2FA keeps you safe" in large dark navy rounded sans-serif type, a simple flat padlock icon to the left, generous margins, no other text.
- 5. A 60-second narration script (Voice Studio): Ever wondered why your password alone isn't enough? Here's the idea in one sentence: two-factor authentication asks for something you know and something you have. First, you type your password, as usual. Second, your phone shows a six-digit code that changes every thirty seconds. Third, you enter that code, and only then are you in. So even if someone steals your password, they still don't have your phone. Set it up once, save your backup codes somewhere safe, and you're done.

## FAQ
Q: What is an AI explainer video generator?
A: A tool that turns a topic or script into a short video explaining one idea, product or process — visuals, narration, captions and music. On Kenerate, Director's Explainer Quick Start drafts the script and shot plan, renders the shots, narrates them in an ElevenLabs voice, adds a music bed and exports one MP4; captions are added afterwards in Auto Subtitles.

Q: How much of the explainer is automated?
A: In Director: the script draft, the shot plan, rendering each shot, the narration, the music bed and joining it all into one MP4. What stays with you: checking the script's facts, approving or redoing shots, pressing Export and running the export through Auto Subtitles for captions. No AI tool knows your product or subject better than you, so the review step matters.

Q: How much does an AI explainer video cost?
A: A 60-second explainer on Wan 3.0 at 480p is about 1,000 credits: 900 for the video, about 54 for 150 words of Eleven v3 narration, 30 for a Ken Music 1.5 bed and 15 for the export, plus a few credits per title card and 20 to caption it in Auto Subtitles at 720p. On Seedance 2.0 at 720p the video alone is 72 credits a second, or 4,320 for a minute. Retakes add to it. One-time packs start at $15 for 1,300 credits.

Q: Is there a free AI explainer video generator?
A: Not for generated video: Director and Video Studio need a paid plan, and a new account's 25 credits don't cover a full explainer. Without a paid plan you can still make a talking-presenter explainer — Voice Studio, Avatar Talk and Auto Subtitles run on credits alone — and nothing carries a watermark.

Q: How long should an explainer video be?
A: Most land between 60 and 90 seconds; training and how-to videos can run 3–5 minutes. Director's Explainer Quick Start offers 30–180 seconds and a film can run up to 10 minutes. Budget about 150 words of narration per minute.

Q: Can I add captions to my explainer?
A: Yes, as a second step. Director's export is an MP4 without captions; press Subtitles on the export (or upload any video) and Auto Subtitles transcribes the speech and burns in captions in one of 10 styles, for videos up to 4 minutes and 100 MB: 20 credits per started minute at 720p, 40 at 1080p. A longer explainer needs splitting into parts of 4 minutes or less first.

Q: Can I use my own voice for the narration?
A: Yes, outside Director: clone your voice from a 3–15 second sample in Voice Studio and use that clip in Avatar Talk or a Kenerate Agent montage. Director's narrator uses ElevenLabs preset voices. YouTube's own help says cloning your own voice for a voice-over doesn't need a synthetic-content label.

Q: Can I make a whiteboard explainer video?
A: Yes. Pick the Whiteboard look in the Explainer Quick Start — hand-drawn black line art on white with simple colour accents. The other looks are Minimal (the default), Illustrated and Cinematic.

Q: Can I make an explainer with a presenter on screen?
A: Yes, in Avatar Talk. Write the script, voice it in Voice Studio, then add a presenter photo and the voice track: Kenerate Avatar lip-syncs up to 10 minutes at 7.5 credits a second (720p). A 60-second presenter explainer is about 450 credits plus the voice and captions — and it doesn't need a paid plan.

Q: Which format should I use?
A: 16:9 for YouTube, websites and training platforms; 9:16 for Reels, Shorts and TikTok; 1:1 for feeds. Set it in the Quick Start before rendering — shots are made in that frame.
