Turn product photos into a video ad draft

A commenter used an ad agent to turn product photos and audience details into a rough video ad with script, b-roll, and voiceover.

What they did
They gave a dedicated ad agent raw product images and a short description of the target audience. The agent produced a first-pass ad by writing the script, making b-roll, and adding voiceover. It also returned scene-by-scene prompts, which let them repair only the weak clip and try that piece again.
How it went
They said this made the process workable and spared them from spending about 20 minutes arguing with a general-purpose LLM every time they needed a fix. They also noted that the output still felt generic unless they guided it closely, so they would not trust it to run without oversight.
Tips
Use it for a draft, not a final cut. Ask for the scene prompts too, so you can revise one part at a time instead of rebuilding the whole ad.

Try it yourself with Manus

I’m making a short video ad for [product]. Use these product photos: [files or links]. My audience is [who they are] and they care about [key needs or interests]. Create a [15-30]-second ad with a script, matching b-roll ideas, and voiceover in a [tone] style. Break it into scenes and show the exact prompt or instructions for each scene so I can edit one scene at a time. Before you send, delete, submit, publish, upload, or otherwise make anything final, pause and ask me to approve the full draft first. Return the draft as text plus any asset files you generate.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
