Turn a Shop Photo Into a Cinematic Promo Video With Google Flow: 3 Prompts to Try

A photo of your shop that is already sitting on your phone can become a drone-style reveal, a build-it-piece-by-piece animation, or a smooth walk through your front door. Creator Marketing Yatra shared a 30 second video showing three short prompts that do exactly that in Google Flow. This post turns that video into a full tutorial, adds the setup steps it skips, and tells you honestly where this approach will let you down.

Credit where it belongs: the three prompt ideas below come from the original video by Marketing Yatra. Go and subscribe if you like quick, practical AI tips for small businesses.

What the Video Actually Shows

The goal is simple: make a short, scroll-stopping clip of your store without hiring a videographer or flying a drone. You upload a photo, type a few words, and the AI does the camera work.

Here are the three prompts, in the order the video shows them:

Prompt	What you get	Photos needed
`City FPV to storefront`	A fast drone-style flight through a city that ends at your shop	1 exterior
`VFX architect assemble`	Your shop built piece by piece, like an architectural animation	1 exterior
`Walk in push through`	A smooth move from the street through the door and inside	1 exterior + 1 interior

One note on the caption. It writes the first prompt with a slash in front of it. That looks like a label, not a command, and I found nothing in Google’s help pages describing slash commands in Flow. Just type the words.

What You Need Before You Start

A Google account and access to Flow. Flow is Google’s AI video workspace, and you can open it here. Availability depends on your country, and one review of Flow found that Google’s own pages disagree on whether a paid plan is required. Check what your account shows.
Credits. Several trackers, including DIYAI, report 50 free credits a day and 1,000 monthly credits on the $19.99 Google AI Pro plan. Google’s own credits page has the current numbers.
Two clean photos. One of your storefront from the outside, one from inside.

Here is how to shoot those photos so the AI has something good to work with:

Stand across the street at eye level and capture the whole front of the shop, sign included.
Shoot in daylight. Avoid harsh glare on the windows.
Move parked cars and clutter out of the frame if you can.
For the interior shot, stand just inside the door and capture the main aisle or counter.
Keep both photos in the same orientation, either landscape or portrait, to match your final video.

Step-by-Step: Your First Storefront Reveal

This follows Google’s own guide to creating videos in Flow. Menus change often, so if a label looks different, trust what is on your screen.

Open Flow on a desktop and start a new project.
Click the model name in the prompt box, then choose Video, then Frames.
Drag your exterior photo into the start frame slot.
Type the first prompt: City FPV to storefront
Pick your preferences. Choose the aspect ratio (9:16 for Reels, Shorts and TikTok), the number of outputs and the clip length.
Click Generate and watch what comes back.

If the result is close but not right, change one thing at a time. Swap the model, ask for another output, or add detail to the prompt. Google suggests using Gemini to brainstorm better prompts if you get stuck.

Prompt 2: Watch Your Shop Get Built

Keep the same exterior photo as the start frame. Replace the prompt with:

VFX architect assemble

The video says this makes your shop appear to assemble piece by piece. It works well as a hook for a grand opening, a renovation or a rebrand, because the story writes itself: look what we built.

Prompt 3: The Walk-Through Transition

This is the one that needs both photos, and it is the most useful for selling an experience.

In the same Frames mode, drag your exterior photo into the start frame.
Drag your interior photo into the end frame.
Type: Walk in push through
Generate.

Google describes frames as a way to create transitions, animate images, or make a video that starts and ends on specific images. That is precisely what a walk-in shot needs. The video itself does not say which slot each photo goes in, so using exterior as start and interior as end is my reading of how Flow handles it.

Make Short Prompts Work Harder

Three or four words can get you a decent first draft. Specific details get you something you would actually post. Luma’s guide to AI video prompts suggests a simple formula: camera movement, subject, action, environment, lighting, mood. Google’s help page says the same thing in plainer terms: be specific about subject, action, environment, lighting and style.

Here are fuller versions I wrote using that formula. I have not tested them on your shop, so treat them as starting points:

Reveal: Fast FPV drone flight over a busy city street at golden hour, slowing down to stop in front of the storefront in the photo, warm light, energetic mood
Assemble: The storefront in the photo assembles piece by piece with clean architectural animation, bricks and signage sliding into place, soft studio lighting, satisfying and precise
Walk in: Smooth forward push from the street through the open door into the shop interior, steady camera, natural daylight, welcoming mood

Two more rules from Google’s tips: make sure your text agrees with your images, and keep the look of both photos consistent. If your outside shot is bright and your inside shot is dim, expect an awkward blend.

Turn Clips Into a Post People Share

A clip on your hard drive does nothing. Here is how to get it in front of people:

Download your best clips and trim any weak seconds.
Stitch them in order: reveal, then assemble, then walk-in. You can do this in Flow’s scene builder or any phone editor.
Add the real stuff on top: your shop name, opening hours and one clear offer.
Post it with a hook in the first line, something like: We turned a photo of our shop into this.
Run a mini challenge. Ask followers to share their own storefront reveal and tag you. People love a before and after, so show the original photo next to the result.

If you want to compare Flow with other AI video tools, my Higgsfield AI review and my post on Perplexity Computer video generation are good next reads.

Honest Limitations

The AI invents what it cannot see. The city, the street and the interior details between your two frames are generated. Do not use a clip to imply your shop looks or sits somewhere it does not.
Signs and text can warp. AI video often garbles lettering. Check that your shop name looks right in every frame, or add it as a text overlay instead.
Credits run out. Higher quality costs far more. Per Luma’s Veo pricing breakdown, one Veo 3.1 Quality clip costs about 100 credits, so test with the cheaper model first.
Results vary. The video shows polished outcomes, but I could not test these exact prompts on a real shop. Expect a few rerolls.
Disclose when you should. Google says Flow outputs carry invisible SynthID watermarks, and many social platforms have AI labelling rules. Check yours before you post.
Access differs by country. Not every feature or plan is available everywhere.

Who Should Try This Today

If you run a cafe, salon, boutique, gym, studio or any shop with a front door, you can test all three prompts in under an hour with two photos. Start with the walk-in transition. It shows what it feels like to step inside, which a still photo cannot do. If you only have budget for one clip, make that one.
