You don't need a camera. You don't need editing software. You don't need video production experience. What you need is a text prompt, a browser, and about 30 minutes.

This tutorial walks through every step of creating and posting your first viral AI video — from choosing a model to uploading to TikTok or YouTube Shorts. By the end, you'll have at least one clip ready to go live.

What AI Video Generation Actually Does

Before diving in, a quick mental model: AI video generators take a text description (your prompt) and produce a short video clip — typically 5–15 seconds. The AI has been trained on massive amounts of video data and can render photorealistic scenes, animations, and transformations from pure text.

No timeline editing. No keyframes. No rendering queues that take an hour. You type → you wait 30–90 seconds → you get a video clip.

The current top models — Sora 2 (OpenAI), Veo 3.1 (Google), Kling 3 (Kuaishou), Seedance 2 — all work on this principle but have different strengths, which we'll cover below.

Step 1 — Choose Your Platform (5 minutes)

Before writing any prompt, decide where you're posting. The ideal clip length, aspect ratio, and hook style differ by platform.

Platform	Ideal clip length	Aspect ratio	Hook style
TikTok	6–15 seconds	9:16 portrait	Hook in first 1–2 seconds
YouTube Shorts	15–30 seconds	9:16 portrait	Hook in first 2–3 seconds
Instagram Reels	7–20 seconds	9:16 portrait	Aesthetic-first or hook in 2s
X (Twitter)	10–30 seconds	16:9 or 9:16	Either works

For your first post, pick TikTok or YouTube Shorts. Both have strong discovery algorithms for new accounts, and 9:16 portrait format is the universal starting point.

Step 2 — Open aicut and Pick a Model (5 minutes)

Open aicut's AI video creator. You'll see a model selector at the top of the creation panel.

For beginners, here's a simple model guide:

Veo 3.1 — Google's model. Exceptional at cinematic quality, natural environments, and atmospheric scenes. Great first choice if you want beautiful, landscape-type clips.

Kling 3 — Handles movement and dynamic transformation well. Good for clips where something changes or moves in an interesting way.

Seedance 2 — Fast generation. Good for iterating on multiple prompt variations quickly when you're not sure which direction to take.

Sora 2 — Strong at photorealistic scenarios, especially unusual or "impossible" scenes that require physical plausibility.

Beginner recommendation: Start with Kling 3 or Veo 3.1. They're forgiving of imperfect prompts and produce reliably strong results.

Step 3 — Write Your First Prompt (5–10 minutes)

This is where most beginners get stuck. The good news: you don't need a perfect prompt. You need a specific one.

The Beginner Prompt Formula

[Surprising subject] + [One clear action] + [Visual style or mood]

Examples:

A golden retriever in a business suit gives a PowerPoint presentation. Photorealistic. Office lighting.
A tiny medieval castle inside a mason jar. The moat ripples as someone lifts the jar. Macro lens.
Cherry blossoms falling upward into a golden-hour sky in slow motion.

All three follow the formula: surprising subject → clear action → visual direction.

5 Prompts You Can Use Right Now

If you're completely stuck, copy one of these verbatim:

A school of glowing jellyfish slowly drifting through an underwater forest. Bioluminescent light, slow motion, cinematic.
A snowglobe falls in slow motion. Inside, a tiny city survives the blizzard. Macro lens, bokeh background.
A person blows dandelion seeds off their hand. The seeds transform into tiny glowing stars. Soft golden light.
An ancient stone wall cracks apart. Ivy and wildflowers explode through every gap simultaneously. Time-lapse.
A cat in a chef's hat carefully plates a gourmet dish. Serious expression. Fine dining kitchen.

Step 4 — Generate and Review (5 minutes)

Paste your prompt into aicut, set the duration (8–12 seconds is a good starting point), and hit generate.

Generation typically takes 30–90 seconds depending on the model and server load.

What to look for when reviewing:

Does the hook (first 1–2 seconds) have a visually interesting frame?
Is there a clear subject that the eye goes to immediately?
Does the motion look smooth, or are there obvious artifacts?

If the output has problems, try one of these fixes:

Problem	Fix
Blurry or muddy result	Simplify the prompt — remove 50% of the descriptors
Action happens too late	Add "OPENING FRAME:" before your subject description
Subject moves weirdly	Switch models (Kling 3 handles motion better than some models)
Too many subjects	Remove all but one subject from the prompt

Generate 2–3 variations before giving up on a prompt. Different seeds produce dramatically different results.

Step 5 — Add a Text Overlay (5 minutes)

Most AI video clips perform better with a simple text overlay. Here's why: roughly 60% of TikTok and Instagram users scroll with sound off. Text tells them what they're watching before they decide to watch with audio on.

What to add:

A one-line concept description: "Prompt: A cat who takes his job extremely seriously"
A hook question: "Would you quit your job to live here?" (for atmospheric clips)
A "wait for it" directive: "Watch til the end" (for clips with a late payoff)

Keep it to one line. Bottom of the frame. Large enough to read without zooming.

You can add text overlays natively in TikTok or YouTube Shorts after upload, or use a free mobile editing tool like CapCut.

Step 6 — Write Your Caption and Post (5 minutes)

TikTok caption formula: [Hook that teases what's coming] [2–3 relevant hashtags]

Example: My AI generated this from a 12-word prompt. #AIvideo #SoraAI #TikTokAI

YouTube Shorts caption formula: [Descriptive title with the keyword] + #Shorts

Example: A Cat Who Takes His Job VERY Seriously — AI Generated #Shorts

Post time: For your first post, time doesn't matter much. Get it live and observe the first 24-hour performance data before optimizing timing.

Beginner Mistakes to Avoid

Writing vague prompts. "A beautiful nature scene" gives the model no direction. "A waterfall surrounded by glowing autumn leaves at dusk, slow motion" is specific enough to produce a coherent output.

Giving up after one generation. The first output is rarely the best. Generating 3–5 variations of the same prompt and picking the best takes 3 minutes extra and usually produces a dramatically better result.

Using too many hashtags. 2–4 focused hashtags outperform 30 generic ones. More hashtags doesn't mean more reach — it means your caption looks spammy.

Waiting for perfection before posting. Post your first clip even if it feels rough. The algorithm rewards publishing history, and you'll learn more from actual data than from pre-posting analysis.

Posting once and expecting growth. Consistency is the primary growth variable. Set a goal of posting 3x per week for 60 days before drawing any conclusions about whether AI video content works for your account.

What to Expect: Growth Timeline

For realistic expectations as a beginner:

Days 1–14: Minimal views. The algorithm needs 10–15 posts to calibrate what your content is and who to show it to.
Days 15–30: You'll start seeing some posts outperform others by 5–10x. These are your early data points — double down on that format.
Days 30–90: If your hook rate (viewers who watch past 3 seconds) is above 30% and your completion rate above 60%, distribution starts compounding.

These are averages. Individual posts can outperform this timeline by orders of magnitude if they hit an engaged audience or get shared by a larger account.
