Image-to-video models can now turn a single product photo into a convincing few-second clip. That is not yet an ad. An ad needs to stop a thumb in the first seconds, show the product in a context the buyer recognises, justify the price and end with a clear next step — while fitting around the buttons and captions each platform overlays on vertical video.

Know the canvas before you generate anything

The 9:16 safe zone

Vertical placements overlay the profile name and “Sponsored” label at the top and captions, CTA and engagement buttons at the bottom and right. Widely used guidance for Meta’s vertical placements is to keep text and essential visuals out of roughly the top 14%, the bottom 35% and about 6% on each side. On a 1080 × 1920 canvas, that is about 270 px at the top and 670 px at the bottom. Always confirm in Ads Manager’s placement preview, which reflects the current interface.

Generate frames with the product in the middle of the frame, not near the bottom. Price tags, offers and logos placed in the lower third will be covered.

A structure for a 15–30 second product ad

Workflow: photos to finished ad

1. Write the storyboard in one line per shot

Describe what the viewer sees, not the camera technique. “Family placing coffee cups on the table” is clearer than “lifestyle shot”. An AI storyboard tool can draft the shot list from product details; edit it so every shot has a job.

2. Generate a still frame for each shot

Create each frame from the real product photo so the product stays identical across shots. Generate the frames in 9:16 from the start rather than cropping a landscape image later. On Stuv, frame images cost about ₹15–₹50 each.

3. Write one motion per clip

Weak motion promptBetter motion prompt
“Cinematic video of the table”“Slow push-in toward the table edge, soft sunlight moving left to right”
“Camera moves around dynamically”“Smooth 30-degree orbit from left to front, table stays centred”
“Make it look premium”“Shallow depth of field, focus pulls from cup to wood grain”

Keep clips at 5–8 seconds; you will trim them. Complex prompts with several simultaneous movements are the most common cause of warped products.

4. Check product fidelity

  • Does the product shape stay constant through the clip?
  • Do logos, prints and hardware stay legible and unchanged?
  • Would a customer receiving this product feel misled? If yes, regenerate — accuracy matters more than a dramatic move.

5. Edit

  • Trim each clip to its strongest 2–5 seconds
  • Add on-screen text for the key message — many viewers watch without sound
  • Add music at a level that doesn’t overpower voice-over if you use one
  • Place all text inside the safe zone and check in the platform preview

Test hooks, not whole videos

Once you have context, detail and end shots, create three to five versions with different first three seconds — a texture close-up, a before/after room, a price reveal, a problem statement. Run them against the same audience and keep the winning hook for the next product.

What it costs with AI

On Stuv, video uses 150 credits per second at 720p and 300 credits per second at 1080p. A five-shot ad made from 6-second 720p clips is 4,500 credits of video plus five frame images. Credits come from your plan, which starts at ₹9,900/month (excl. GST).

Tools to do this in one place: Video Storyboard for shot planning, frames and clips, AI product video for individual clips, and the Video Editor for trimming, captions and music.

Frequently Asked Questions

What size should an Instagram Reels ad be?

How long can YouTube Shorts be?

Since 15 October 2024, Shorts can be up to three minutes long for square or vertical videos.
