Create Professional Promotional Videos with AI: A Step-by-Step Guide

Promotional videos have become one of the most effective ways to communicate a message. They're easy to understand, memorable, and capable of reaching massive audiences. Here's what's interesting: with artificial intelligence now accessible to everyone, creating these videos has shifted from a specialized skill requiring expensive equipment to something virtually anyone can do in an afternoon.

Today's AI tools make producing promotional videos faster and more straightforward than ever before. You need three basic ingredients: a solid script, some visual references, and access to the right AI platforms. The result? Professional-quality videos with smooth animations, natural-sounding voiceovers, and polished effects—all without hiring a production crew. This approach saves tremendous time while delivering impressive multimedia content suitable for educational campaigns, public awareness initiatives, or information sharing.

How to Create a Promotional Video: A Complete Walkthrough

Step 1: Generate Your Script

Start by crafting a promotional script about your topic. Try using this prompt template with ChatGPT:

I'm an elementary school teacher. I need to develop a promotional script about [your topic]. The content should be approximately 5 sentences—concise, easy to understand, and appropriate for elementary-age students.

Wait for ChatGPT to generate a short, focused script. For example, if your topic is traffic safety, the AI will tailor the message to that theme.

Next, generate a visual reference image using this detailed prompt:

Step 3: Break Down Your Script Into Video Scenes

Now you'll convert your script into individual scene prompts for video generation. Use this master prompt:

Use the image created above as a reference.

Analyze the Vietnamese script below and break it into multiple Veo 3 commands.

Mandatory Requirements:

• Each command generates exactly one scene lasting 8 seconds.

• Maintain 100% consistency with the Vietnamese teacher character from the reference image, including face, hairstyle, skin tone, clothing, posture, facial expressions, and voice.

• Keep the same modern school broadcasting studio with professional microphone, blue LED screen, cinematic lighting, and educational television aesthetic.

• Character looks directly at camera, natural hand gestures, smooth movements, realistic expressions, and perfect lip-sync with Vietnamese dialogue.

• Camera angle: frontal view, medium shot, subtle cinematic movement.

• Background screens display only icons and illustrations related to the topic.

• Style: Premium 3D cinema animation, cinematic lighting, ultra-realistic texture, volumetric lighting, depth of field, highly detailed, 4K Ultra HD.

• No Vietnamese text on screens.

• No subtitles.

Formatted output table with columns:

1. Scene Number

2. Main Content

3. Complete Veo 3 Command

4. Vietnamese Dialogue (8 seconds)

5. Character Consistency Notes

Each Veo 3 prompt must meet these requirements:

• Ready to copy and use immediately.

• Complete description of character, setting, actions, camera angle, lighting, emotion, and dialogue.

• Faithful to the original script.

• Scenes transition logically so they assemble into a complete, cohesive educational promotional video.

Scene-by-scene video generation commands

ChatGPT will now generate individual scene commands based on your script. Copy each scene prompt and paste it into Veo 3 or Google Vids to produce the actual video footage. Reference the poster image you created earlier for consistency across all scenes.

Generating video for each scene

Log into Veo 3 or Google Vids, then input each scene command to generate video clips. Once you have all your scenes, stitch them together into a finished video.
