Viral AI video is no longer an experiment — it's a repeatable production system. The accounts generating millions of views monthly on TikTok, YouTube Shorts, and Instagram Reels are not relying on luck. They're following a set of principles that consistently produce high-performing content.

This guide covers the complete workflow: choosing the right model, writing prompts that produce strong hooks, structuring your content for each platform's algorithm, and building a posting cadence that compounds over time.

The Viral AI Video Stack

Before getting into tactics, a clear mental model. Making viral AI videos has three layers:

Production — generating high-quality clips with the right model and prompt
Hook engineering — structuring the clip so the first 2–3 seconds demand attention
Distribution strategy — posting the right content on the right platform at the right cadence

Most tutorials cover Layer 1 only. Layers 2 and 3 are where the difference between 500 views and 5 million views actually lives.

Layer 1: Production — Models and Prompts

Choosing the Right AI Video Model

The AI video model you choose shapes what's possible. Each current top model has a specific strength:

Model	Best for	Access via
Sora 2	Photorealistic impossible scenarios, physics-based "what if"	aicut
Veo 3.1	Cinematic quality, environmental detail, atmospheric scenes	aicut
Kling 3	Dynamic motion, transformation, physical interaction	aicut
Seedance 2	Fast iteration, batch production	aicut
Grok Imagine	Stylized visuals, creative scenarios	aicut

The most common mistake beginners make: using one model for all content. Different viral formats need different models. Use aicut to access all of these from one dashboard and match each prompt to its optimal model.

Writing Prompts That Produce Viral Output

The viral prompt formula:

[Unexpected element] + [Clear action] + [Camera/lighting direction] + [Physical or aesthetic detail]

Example: A cat in a three-piece suit [unexpected] argues with a lobster at a conference table [action]. Medium shot, two-camera dialogue setup [camera]. Warm mahogany office lighting [aesthetic].

The four most consistently viral AI video formats:

1. Impossible physics — something that can't happen, rendered photorealistically. Rain falls sideways. Water flows upward. Shadows have volume. Sora 2 is the model for this.

2. Transformation — something changes dramatically in under 10 seconds, creating a natural loop. A concrete wall becomes a garden. A figure dissolves into birds. Kling 3 handles these best.

3. Surreal humor — an absurd scenario played completely straight. A golden retriever in a business suit presents a quarterly report. Penguins run a sushi restaurant. Kling 3 or Seedance 2.

4. Cinematic atmosphere — a visually stunning environment clip that earns saves and re-watches. Cherry blossoms fall over a lit Tokyo alley. A lighthouse beam sweeps across a rough sea. Veo 3.1.

Prompt iteration workflow:

Write the core prompt (subject + action)
Generate once
Add specificity where the output felt generic (camera angle, lighting, physical detail)
Generate 2–3 more variations
Pick the best output from the batch

Three total generations per prompt is the realistic sweet spot. More than five and you're over-engineering; fewer than two and you're not extracting the model's full range.

Layer 2: Hook Engineering

Hook rate — the percentage of viewers who watch past the first 2–3 seconds — is the single most important metric for algorithmic distribution. Below 30%, the algorithm throttles your clip. Above 50%, it distributes aggressively to new audiences.

Designing the Opening Frame

The opening frame is your thumbnail equivalent in short-form video. Because platforms auto-play in the feed, the first frame appears before the viewer has made any decision about watching. If it's a low-energy frame — an empty scene, a slow buildup, anything that doesn't immediately register as interesting — viewers scroll before the action begins.

How to engineer the opening frame in your prompt:

Add "OPENING FRAME:" before your prompt and describe the most visually interesting static composition you can imagine for this scene. The model will use this as an anchor for the clip's opening.

Example: OPENING FRAME: A perfectly still mountain lake at dawn, the entire orange sky reflected in glassy water. Then: a single raindrop falls and shatters the reflection into a million rippling arcs.

The opening frame (still lake + perfect reflection) is designed to earn a 2-second hold before anything happens. Then the raindrop event extends the watch.

The Hook Pattern That Works Across Platforms

The opening 2 seconds should create a question in the viewer's mind — something they need to see resolved. This can be:

A visual tension that demands resolution (rain frozen in mid-air — what happens when it moves?)
A scenario so absurd the brain needs 2 seconds to process it (a knight in full armor in a coffee shop line)
A physical event that starts mid-action (the clip opens on something already happening, not building to it)

The worst hook patterns: slow pans, establishing shots, gradual buildups, nature b-roll with no event. These all reduce hook rate below the distribution threshold.

Layer 3: Distribution Strategy

Platform-Specific Format Rules

The same clip optimized differently for each platform performs significantly better than a generic cross-post.

TikTok:

Hook in frames 1–2 (not 1–5)
Surreal humor and impossible physics drive shares and re-watches — the two strongest virality signals
Caption: 1 line + 2–3 hashtags maximum
Optimal length: 6–15 seconds

YouTube Shorts:

Slightly more tolerance for a 3–5 second build if the opening frame is strong
Cinematic atmosphere performs well — YouTube renders at higher quality and surfaces content in search
Title with keyword matters: YouTube is a search engine. "A city where gravity works sideways — AI generated" beats "cool ai video #shorts"
Optimal length: 15–30 seconds

Instagram Reels:

Saves and shares are the primary algorithmic signals — aesthetic content (cinematic atmosphere category) earns saves; shareable content earns shares
Silent viewers are a higher proportion than TikTok — text overlay is essential
Optimal length: 7–20 seconds for loop performance

Building a Posting Cadence That Compounds

Algorithmic distribution on all three platforms rewards:

Posting frequency and consistency
Viewer return rate (subscribers who come back)
Individual clip performance metrics

The account-level strategy that compounds:

Pick one format series (e.g., "Daily What If?" or "AI Realities") and post it consistently. Viewers who enjoy your "impossible physics" clips subscribe expecting more. This builds viewer return rate, which multiplies distribution on every subsequent post.

Batch production is the unlock. Generating 15–20 clips in a single 2-hour session is realistic with aicut. You batch-write 20 prompts, generate them in parallel across models, review and select the best 12, add captions, and schedule the week's content. Daily posting without daily production effort.

The 90-day rule. Short-form algorithms typically take 30–90 posts to calibrate your content and identify your audience. Don't evaluate your growth strategy before 90 days and 90+ posts of consistent posting.

What Actually Goes Viral vs. What Should Go Viral

A few counterintuitive observations from accounts that have cracked viral AI video:

Technical quality matters less than hook quality. A slightly lower-fidelity clip with an exceptional opening 2 seconds outperforms a photorealistic clip with a weak hook. Get Layer 2 right before optimizing Layer 1.

Humor outperforms beauty at sharing. Aesthetic clips get saves. Funny clips get shares. Shares drive the fastest growth because they reach audiences outside your existing follower base. If your goal is velocity, lean toward the surreal humor format.

The re-watch mechanism is more important than length. A 7-second clip that naturally loops and earns 3 re-watches per viewer outperforms a 30-second clip watched once. Build for re-watch by engineering loop points into your prompts (clips that end where they began, or end on a visual tension that sends the viewer back to the start).

Key Takeaways

Making viral AI video is a three-layer system: production (models + prompts) → hook engineering (first 2–3 seconds) → distribution strategy (platform-specific format + consistent cadence).
The four most reliably viral formats are impossible physics, transformation, surreal humor, and cinematic atmosphere — each has an optimal model.
Hook rate (viewers past 3 seconds) is the primary algorithmic signal. Engineer the opening frame explicitly in your prompt.
Daily posting through batch production is achievable: write 20 prompts, generate in one session, schedule the week.
Allow 90 days and 90+ posts before evaluating your growth strategy.
