Why CGI Ad Prompt Are Important
Before we start, let’s talk about why prompts are so important. Veo 3.1 and other AI video generators only understand what you tell them. If you write vague instructions, the video will look random or unrealistic. If you write clear, step-by-step instructions, the AI can create videos that look like they were made by professionals.
Think of a prompt as a mini script for a movie. You tell the AI:
- What the product is
- Where it is
- What time of day or lighting
- How the camera moves
- What sound plays
- Any human emotion
- The final logo or tagline
The better you are at describing, the better the final video. That’s why learning to write Veo 3.1 CGI ad prompts is one of the most useful skills today.
Step 1: Start With the Product or Main Focus
Every prompt must begin with the main object or product. Don’t start with extra details yet. Keep it simple and clear.
Example:
“A matte black electric scooter rides on a wet city street at sunset.”
This one line tells the AI: the main object (scooter), the location (city street), and the mood (sunset).
Tip: Always describe only one main object per scene. If you add too many objects, the AI might not know which one to focus on.
Step 2: Add Visual Mood and Lighting
After stating the product, tell the AI about visual mood. These include lighting, weather, or general feeling. Use simple words like: sunset, dawn, night, soft glow, neon lights, warm light, soft shadows.
Example add-on:
“Warm orange light reflects on the wet street, neon signs glow softly in the background.”
Why this works: Lighting makes the scene realistic. Even if the AI can make objects, it needs cues for the environment.
Extra Tip: Words like “soft,” “gentle,” or “warm” give a realistic cinematic feel.
Step 3: Specify Camera Angles and Movements
Next, tell the AI how the camera should move. You can describe angles, zoom, and movement.
Example:
“Start with a wide drone shot from above, then slowly zoom to a side close-up of the scooter and rider.”
Why it’s important: Camera movement makes your video look like a real ad. Without this, AI may create static or awkward shots.
Extra Tip: Keep it simple. One or two camera movements are enough. Too many instructions can confuse the AI.
Step 4: Add Human Action or Emotion
Even one small human action can make your video relatable and emotional. AI videos look flat if no human presence is included.
Example:
“The rider is a young person in casual smart clothes, smiling with calm pride.”
Why: People connect to emotions. One small action like a smile, nod, or hand gesture makes the ad more appealing.
Tip: Keep it short. One action or one emotion per scene works best.
Step 5: Add Sound and Voice Lines
Sound is key to realistic videos. You can include background music, ambient sounds, or a voice-over.
Example:
“Soft ambient city music and a low electric hum. Voice-over in Hindi says, ‘Agla padav — shuruaat apki.’”
Why: AI will understand the mood and timing better. Voice-over adds a call-to-action or a tagline naturally.
Extra Tip: Keep voice lines very short. Three to six words are enough.
Step 6: Add the Ending Logo or Tagline
Always include a final frame with the logo or tagline. This gives your video a professional finish.
Example:
“End shot: Scooter parked in front of a glass office building. Fade in logo: ‘EcoDrive – Future is Now.’”
Why: Ads need a clear ending to feel complete. AI will follow this instruction if you include it in the prompt.
Step 7: Keep Sentences Short and Clear
AI reads better short and clear sentences. Avoid long, complicated lines. Stick to simple words.
Extra Tips:
- You have to use everyday words only.
- You have to avoid poetic phrases.
- Just Focus on one detail per sentence.
- You can Test one change at a time if the output is not perfect.
