The video below is 100% AI-generated — from the visuals to the audio. Watch it to see what's possible, then scroll down to learn every step of the process.

By the end of this guide, you'll know exactly how to:

• Set up a monetizable YouTube channel
• Find low-competition, high-growth niches

• Edit everything together into a viral-ready video

A bad niche = wasted effort. A great niche = consistent growth. Use this winning formula to find yours:

Two Essential Tools for Niche Research

Winning Niches for 2026

Before you create a single AI video, you need a place to publish it. Here's the fastest way to create a YouTube channel directly from your mobile device:

Create Channel on Mobile

1. Open the YouTube app on your smartphone
2. Tap your profile picture in the top-right corner
3. Select "Your Channel" from the menu
4. Click "Create Channel"
5. Enter a channel name that matches your chosen niche (more on this below)
6. Tap "Create" — your channel is live!

The entire AI video creation process follows a clean 5-stage pipeline. Each stage uses a specific tool, and the output of one stage becomes the input for the next:

We'll now walk through each stage in detail, starting with the foundation of every great AI video — the prompts.

AI video generators like Google Veo 3 work best with highly detailed, structured prompts. Instead of trying to generate one long video, we'll break your content into 8-second scenes and get ChatGPT to write a unique prompt for each one.

The 4-Step Process

Make an AI video prompt for an 8-second AI video about a Lay's chips production from start to finish. Give each section 8 sec video prompt separately. The video should look natural and real. Make sure each section has detailed prompts and clear thoughts. Since it is for Google Veo 3 video, it needs very clear and detailed instructions.

Scene 1 (8 sec) — Potato Harvest

Ultra-realistic cinematic documentary footage of a large potato farm at sunrise. Farmers operate modern harvesting machines that gently lift fresh golden potatoes from rich brown soil. Potatoes roll onto conveyor belts attached to the harvester while dust softly rises in the morning light. The camera begins with a wide aerial drone shot, then smoothly transitions to a low-angle tracking shot beside the moving harvester, showing potatoes falling into collection bins. Warm golden sunlight, realistic shadows, natural wind moving the crop leaves, highly detailed soil texture, authentic farming equipment, subtle camera shake as if filmed by a professional cinema camera. Photorealistic, 8K quality, HDR, shallow depth of field, natural colors, no text, no logos, no watermark.

Now comes the magic. You have 8 polished prompts — time to turn each into an 8-second video clip using Google Flow, the mobile app powered by Google's Veo 3 model.

Step 1: Install Google Flow

• Open the Play Store (Android) or App Store (iOS)
• Search for Google Flow or Google Veo
• Install the app and sign in with your Google account

Step 2: Configure Settings

Step 3: Generate Each Scene

1. Open the app and tap "Create" or "Generate"
2. Paste your first scene prompt (Scene 1 from ChatGPT)
3. Hit "Generate" and wait 5–10 seconds
4. Repeat for all 8 scenes

Understanding the Free Credit System

You have two paths for audio, and the right choice depends on your video style:

Step 1: Get Voiceover Scripts from ChatGPT

Return to the same ChatGPT conversation and paste this prompt:

Generate a text to audio prompt for this video for each section. Give me short voiceover scripts for each 8-second scene that I can convert to audio.

ChatGPT will return a script for each scene:

Step 2: Generate Audio Files

You have two excellent free options:

Step 3: Convert WAV to MP3 (Critical Step!)

Solve this instantly with our free converter tool:

Step 4: Repeat for All 8 Scenes

Generate script → Create audio → Convert to MP3. Do this for every scene. You should end up with 8 MP3 files, one per scene.

Your thumbnail is the first impression. A bad thumbnail kills even the best video. Let's create one that stops the scroll.

Step 1: Generate Thumbnail Prompt with ChatGPT

In your same ChatGPT conversation, ask:

Write a small prompt to make an attractive thumbnail for this video about Lay's chips production.

ChatGPT will return something like:

Close-up shot of crispy golden potato chips flying in the air with a factory background. Bright yellow and red colors, text "LAY'S PRODUCTION" bold. High quality, professional look, eye-catching, 4K.

Step 2: Resize to YouTube Thumbnail Size

YouTube thumbnails must be 1280×720 pixels (16:9 ratio). Our free tool does this instantly:

Time to bring everything together. By now you have:

Step 1: Install & Set Up CapCut

1. Download CapCut from the Play Store or App Store
2. Open the app and sign in
3. Tap "New Project"
4. Set aspect ratio: 16:9 for long videos, 9:16 for Shorts

Step 2: Import & Arrange Videos

1. Tap "Import"
2. Select Scene 1 video, then add it to the timeline
3. Add Scene 2, Scene 3, and so on in order
4. Arrange them sequentially (1 → 2 → 3 → ... → 8)

Step 3: Add Voiceover Audio

1. Tap the "Audio" tab at the bottom
2. Click "Import" and select your first MP3
3. Drag it directly under Scene 1's video
4. Repeat for all 8 scenes, matching each audio to its scene

Step 4: Add Text Overlays

Text helps viewers follow the story and boosts engagement:

1. Tap the "Text" tab → "Add Text"
2. For each scene, add a descriptive label: "Potato Collection", "Washing Process", "Peeling & Cutting", etc.
3. Use bold fonts (30–40 size)
4. Color: white or yellow for dark backgrounds
5. Position: bottom center or top center
6. Add fade in/out animations for polish

Step 5: Add Stickers (Anti-AI Detection)

How to add stickers the right way:

1. Tap "Stickers" tab
2. Search for: "Subscribe", "Like", "Bell", "Arrow", "Question mark", "Fire", "Star"
3. Place stickers at random moments throughout the video
4. Keep each sticker visible for 2–3 seconds
5. Rotate some stickers for variety
6. Set some to 50% opacity for subtle effects

Step 6: Add Background Music (Optional)

1. Open the "Audio" tab → "Sound"
2. Search for royalty-free music (CapCut has a library built-in)
3. Add the track as a background layer
4. Keep volume at 10–20% so voiceover stays clear

Step 7: Export Your Final Video

Tap "Export" and wait for your video to render. Once ready, upload it to YouTube and add your custom thumbnail from Stage 4!

Pro Tips for Maximum Success

• Generate unique prompts for each scene — never reuse the same one
• Always use VE 3 in Google Flow, Not Omini will cut more credits
• Every video clip must be exactly 8 seconds
• Add stickers to avoid AI detection and boost engagement
• Always convert .wav to .mp3 before importing to CapCut
• Invest time in thumbnail design — it determines your CTR
• Use text overlays and stickers in your final edit
• Only use royalty-free music to avoid copyright strikes
• Record voiceovers in a quiet environment if using your own voice
• Target ~1 minute total length (8 scenes × 8 seconds)

Common Mistakes to Avoid

• Using the same prompt for all 8 scenes
• Importing .wav audio directly into CapCut
• Forgetting to add stickers (risks AI detection)
• Uploading unedited clips without assembly
• Publishing videos without a custom thumbnail
• Selecting "Omini" instead of Veo 3 in Google Flow
• Using copyrighted music without licensing
• Skipping audio sync checks
