A product photo shows the item. An ad still has to do a little more: sit in a 1:1 feed, a 9:16 story, or a 16:9 banner, leave room for a line of type, and feel like a designed frame rather than a raw packshot dropped into a template. You can build that frame from a prompt, and you can use the real product photo as a reference so the bottle or the jar stays recognizable.
The AI ad generator on CanvaPro takes an optional reference image — JPG, PNG, or WEBP up to 8 MB — and a required prompt. A Generate AD Prompt helper can draft that sentence for you. You pick Square 1:1 (the default), Portrait 9:16, or Landscape 16:9, then click Generate Ad and wait about a minute. The result is a draft creative, not a finished, legally reviewed campaign. If the product still is too tight for the ratio you need, the AI image extender can add Height or Width, from 0 to 2,000 pixels, on a JPG or PNG up to 5 MB, so you have a wider or taller still to use as the reference or as a clean base.
Write a prompt that is specific and honest
Name the product, the surface, the light, and the placement. “Square ad still of this amber honey jar on a wooden table, soft window light, a small spoon of honey beside the jar, plenty of quiet space at the top for a short headline, no invented claims on the label” is easier to review than “best luxury ad ever.” If the helper writes a glowing slogan, edit or delete claims you cannot stand behind.
Do not ask the tool to invent a certification, a discount, or a review quote. Those belong in a layout you control, after you have checked the facts. Generated typography is also easy to misspell. Prefer a quiet still, then add the real headline in your own editor.
If the packshot itself is still a hallway photo, make a clean white background product photo first, then use that still as the reference.
A practical sequence
- Choose the ratio for the placement: 1:1 for many feed units, 9:16 for stories and some reels, 16:9 for a wide banner or a video cover.
- Extend a tight packshot if the jar already fills the frame and you need margin for type, then save a JPG under the reference limit.
- Upload the product photo as the reference, write or tidy the prompt, and generate the ad draft. Wait for the preview.
- Check the jar, the label, and the scene against the real product. Add your own headline and a truthful line of copy in a separate step.
A slightly flat packshot is worth cleaning first with the image enhancer so the jar or the label reads clearly in the ad frame.
What to review before anyone else sees it
The bottle should still be your bottle. A shifted label, a new lid color, or a honey that looks darker than the real jar will confuse a shopper and can become a claim problem. Look at hands, spoons, and props the model invented; remove or avoid anything you would not put on a real set. And look at type, if any appeared: a misspelled word in a 1080-pixel ad is still a misspelled word.
Rights matter. Use a product photo you own or are allowed to advertise with. Do not drop a competitor’s still in as the reference. If a person appears in the draft, you need a right to show them. Drafts are starting points; a live campaign still needs your usual review for claims, music, and likeness.
For a prompt-only draft with no product still, the walkthrough on how to generate an ad creative from a prompt is the closer starting point.
A short checklist
- Pick 1:1, 9:16, or 16:9 first, and extend the packshot if the frame is too tight.
- Use a reference photo under 8 MB, write a clear, modest prompt, and treat typography in the generate as something to verify or replace.
- Compare the draft to the real product, and only add claims you can support.
- Keep the original product photo, and review rights before you run the still as an ad.
When the prompt and the reference still are ready, open the ad generator again, pick the ratio for that placement, and generate one draft at a time.
Variants for each placement
One reference jar can support more than one ratio, but each ratio is its own generate. Do not crop a 1:1 draft into a 9:16 story and hope the jar still sits well; run a 9:16 generate, or extend the packshot to a tall frame first so the helper and the model see the real shape. Keep a short note of the prompt that worked, and change only the placement line when you make the next size, so the set looks related.
If you need three variants for a test — a clean table, a breakfast setting, a tighter hero — change one thing at a time and keep the label honest in all of them. A test that also changes the lid color is no longer a test of the scene. And when a draft is close, it is often faster to add your headline on that still than to generate again in search of a perfect built-in slogan.
A single, honest draft that still looks like your jar is more useful than a folder of dramatic scenes that no longer match the product. When you are ready, start with one placement and one reference still, generate a quiet frame, and add the real words yourself.
When you need a short motion version of the same hero still, turn the product photo into a short video after the static ad is locked.
