Happy Horse Prompts for Explainer Videos

Explainer videos have a different job than ads or UGC. They need to be clear first, then compelling. Every visual should support the verbal narrative - not compete with it. That constraint actually makes happy horse prompts explainer videos easier to write than ad prompts, because you're optimizing for focus and coherence rather than surprise and scroll-stopping energy.

Happy Horse 1.0 - Alibaba's 15B-parameter text-to-video model, currently #1 on Artificial Analysis - is well-suited to this task. Its joint audio+video architecture means scenes sound like they look, and its coherent motion across the full 5-second window prevents the distracting drift that breaks viewer focus.

All four prompts below are ready to run at VIDEO AI ME, which gives you Happy Horse 1.0 alongside Seedance 2 under one subscription.

Prompting Strategy for Explainer Footage

Explainer video b-roll needs to do one thing: illustrate the point the narrator is making. That means your prompt must be legible and precise.

Two rules matter more here than anywhere else:

Single action per prompt. If your narration says "open the app and see your dashboard," your video prompt should show one thing: a hand unlocking a phone, OR a face looking at a screen. Not both. Cut on the edit.

Avoid movement complexity in the subject. Explainer footage works best when the subject holds mostly still and the camera does the moving, or vice versa. Two independent moving elements (subject walking + camera panning) introduce attention split.

For lighting: "overcast diffused daylight" and "single soft key from camera-left" are your two reliable defaults for explainer footage. They're readable, they don't create distracting shadows, and they read as professional without looking like a studio.

4 Ready-to-Copy Happy Horse Prompts for Explainer Videos

Prompt 1 - The Product in Use (20-word, clean)

The most common explainer cutaway: a person using a product, clearly visible, no distractions.

A woman at a clean white desk types on a slim laptop, morning light from a window camera-left, static medium shot, calm and focused.

What's doing the work: "clean white desk" removes visual clutter, "morning light from a window camera-left" is a real, soft light source, "static medium shot" prevents camera movement from pulling focus.

Prompt 2 - Concept Illustration: Growth or Progress (20-word)

For abstract concepts like growth, scale, or momentum, ground the metaphor in a physical action.

A time-lapse of seedlings pushing through dark soil toward overcast morning light, camera static, tight medium shot, no movement in frame except the plants.

This is the kind of cutaway that works over narration about "your business growing" or "building a foundation." The constraint "no movement in frame except the plants" keeps the model focused.

Prompt 3 - The Talking-Head Explainer Setup (Markdown sections)

For an on-camera presenter or AI actor segment, the markdown section format gives you the most control over the composition and performance cues.

## Subject
A man in his late 30s, clean-shaven, wearing a medium-blue button-down shirt. Relaxed, authoritative posture.

## Action
He gestures with one hand toward camera-right, as if pointing to a screen or whiteboard. Then returns his hand to the desk. He speaks directly into the lens.

## Setting
A minimal home office: plain off-white wall behind him, a bookshelf softly out of focus at frame edge.

## Camera
Static medium close-up. Lens slightly longer than 50mm - mild background compression.

## Lighting
Single soft key from a large window camera-left. Gentle fill from the wall camera-right. No hard shadows.

## Mood
Professional but approachable. Conversational.

This is the template to pair with VIDEO AI ME's AI actor feature. Generate this clip, then use the multilingual AI actor to voice the explainer in English, Spanish, French, German, or any supported language. The lip-sync maps to the generated face with no re-shooting.

Prompt 4 - The Before/After Scene Pair (Shot list)

The most persuasive structure in explainer video is contrast. This shot list builds it directly into a 5-second clip.

Shot 1 (wide establishing, 0-2s): A person at a desk surrounded by papers and sticky notes, harsh overhead light, slightly hunched posture, multiple browser tabs visible on a blurred monitor behind them.
Shot 2 (mid tracking, 2-4s): The same desk cleared, the same person sitting upright, single document open, soft window light from camera-left.
Shot 3 (slow push-in close, 4-5s): Close-up of their hands on the keyboard, relaxed grip, the light catches the surface of the keys softly.

Shot 3's specificity - "relaxed grip, the light catches the surface of the keys softly" - adds tactile realism that makes the transformation feel earned rather than theatrical.

Structuring a Full Explainer With Multiple Clips

Happy Horse generates 5-second clips. A 90-second explainer video needs roughly 18 of them. Here's how to structure your prompt set efficiently:

Map the script first. For each sentence or idea in your narration, write one prompt. One prompt = one visual idea.
Keep environments consistent. If your explainer takes place in one setting (a home office), keep the same environmental descriptors across prompts: same desk surface, same window direction, same light quality.
Vary only the action. The subject's action should change clip to clip. The environment and lighting should not drift.
Use markdown sections for your presenter clips. The format produces the most consistent look across multiple clips.

VIDEO AI ME lets you run Happy Horse and Seedance 2 side by side. For explainer content, Happy Horse's photorealism tends to win on human subjects; Seedance 2 may perform better on certain stylized or abstract concepts. Testing both is fast.
