AI Explainer Video Generator: Explain Anything in 30 Seconds
Turn a process, product, or concept into a short visual clip — without a $5,000 studio quote or an animation timeline.
Describe what needs explaining and Pellucida plans it into a segment-by-segment storyboard you edit before rendering. The output is a narrated 15-30 second MP4 with subtitles — real scene footage, not a template animation.
See it on a real example
Treadmill intro for new gym members: clip the safety key to your clothing before starting, begin at a walking pace, hold the side rails only when stepping on or off, and press the red stop button if you lose your footing.
How it works
Describe what to explain
Write two to five sentences: what it is, who it's for, and the steps or ideas to cover. The AI plans it as a sequence of short visual segments.
Edit the storyboard
Each segment has a keyframe, a scene prompt, and a narration line. Adjust the explanation, reorder scenes, or cut a segment — all before rendering.
Render the finished clip
Segments render into scene footage, AI voiceover and subtitles are added, and you download one 15-30 second MP4 ready to embed or post.
What can an AI explainer video generator do?
An explainer used to mean two options: pay an animation studio $5,000 or more and wait weeks through scripting, storyboarding, and revision rounds — or learn a DIY animation tool and spend evenings dragging keyframes. Pellucida takes a third route. You describe the process, product, or concept in plain language, and the AI plans a 15-30 second clip as a sequence of real scenes: a member stepping onto a treadmill, a safety key clipping onto a shirt, a hand pressing the red stop button. Every segment has an editable prompt and narration line, so you steer the explanation before any rendering spends credits. The result is scene-based footage with AI voiceover and subtitles, delivered as a finished MP4. It fits the places long explainers never reach: a product page above the fold, an onboarding email, a lobby screen, the first minute of a demo call.
Why make explainer videos with AI
- Studio explainers run $5,000+ and take weeks; here the storyboard appears in minutes and a revision is a text edit, not a change-order email.
- DIY animation tools have a real learning curve — layers, easing, keyframes. Here the input is sentences, and the output is already a finished MP4.
- Viewers give you about 30 seconds before deciding whether to keep watching. A clip built to that length beats a 3-minute video watched to 20%.
- Products and processes change. Re-rendering an edited storyboard costs minutes; re-engaging a studio for version two costs another invoice.
- At this cost per clip, you can make one explainer per feature or per FAQ instead of cramming everything into a single overloaded video.
How to get the best results
Pick one idea per clip. 'How our gym works' is a series; 'how to start the treadmill safely' is one explainer. Write the brief in the viewer's order: what they see first, what they do next, how it ends. Use concrete nouns — 'the red stop button', 'the clip-on safety key' — because those become the actual scenes; abstract phrasing produces abstract footage. Mind the narration budget: 15 seconds carries roughly 35 spoken words and 30 seconds about 70, so if your explanation runs longer, split it into two clips rather than rushing the voiceover. In the storyboard review, read each segment's narration line out loud — anything you stumble over, a first-time viewer will too. Finally, match the aspect ratio to the placement: vertical for social feeds and phone-first audiences, horizontal for websites, demo calls, and screens in your space.
What makes a good explainer video
- One clear takeaway — the viewer should be able to repeat the point in a sentence.
- The thing being explained is visible in the first scene; no logo intro eating three of your thirty seconds.
- Real objects and environments on screen, not abstract stock metaphors like handshakes and lightbulbs.
- Narration in words a first-time viewer already knows — no internal jargon.
- Subtitles throughout, because most feeds and lobby screens play muted.
- An ending that shows the completed state or the next action, not a fade to a slogan.
