AI product videos for ecommerce — a three-shot commercial recipe
Turn one product photo into shop-ready video and listing stills on eroq, with the right format per channel and the credit math for a full product page.
You have one product photo, a listing that needs stills, and three placements that each want a different shape. The job is not "make a video" — it is turning a single reference into a small, consistent set of assets, then doing it again for the next SKU without renegotiating the look. This is the recipe we use for that, with the arithmetic at the end. The short version is on the product videos use case.
The product goes in as an Element
Before you write a prompt, put the product into Elements — the library of reusable places, objects and styles, up to 50 per account, each one @mentionable in any prompt. A product Element holds a name, a description and reference photos.
That last part is the whole article. The photos are used as references, so the engine works from your actual product instead of inventing a lookalike; with a single photo the render becomes image-to-video and the engine animates the real thing. Customers do not consciously read a label in a 5-second clip, but they notice when it is wrong.
Set the Element up once and every ad this quarter is @mention plus a sentence.
A three-shot commercial
Three shots cover almost every product. Shoot them at 5 seconds each and cut hard:
- The reveal — the product alone on a clean surface, slow push-in, wide-ish framing, deep focus.
- The detail — macro lens at f/1.4, slow pan across the material, the shot that sells the texture.
- The use — handheld, hands in frame, daylight, the shot that sells the life around it.
The director's rack does most of the styling for you and folds into the prompt server-side. For a commercial look, set Film type "Commercial", Tempo "Dynamic", Camera gear "35mm film", Palette "Warm film" and Lighting "Window light", then change only the Lens and Aperture between shots — Macro at f/1.4 for the detail, clean and sharp at f/11 for the reveal.
Here is shot one, complete, for a ceramic pour-over dripper:
A matte white ceramic pour-over dripper sits alone on a pale oak counter, slow push-in from three quarters as a thin ribbon of steam rises past it, soft window light from the left with a warm bounce card on the right, clean sharp lens at f/11, dust in the air, calm tempo, commercial look on 35mm film, wide frame.
Build the three shots as one storyboard in Cinema mode rather than three separate renders. Scenes are added one at a time and each renders immediately, up to 12, and you can re-render, edit, reorder or duplicate any of them, shoot 1 to 4 takes per scene, and watch the whole thing in the assembled player. Drafts save as "My films", so next season's version starts from this one.
One shape per channel, not one crop
Video runs 16:9 wide, 9:16 vertical and 1:1 square; images add 21:9, 4:3 and 3:4. Shoot the hero shot in each aspect ratio you actually publish to rather than cropping one master, because a crop throws away the headroom you composed for. Vertical for TikTok and Reels, square for feed placements, wide for the product page and YouTube.
Ads mode in the video tool is worth a pass here: it ships ad templates such as "UGC testimonial" with the brief already shaped, and your product Element drops straight into them.
Listing stills with Image One
The product page needs more stills than clips. Image One is the photoreal model at 1024×1024 for 10 credits an image, with batches of 1 to 4, reference photos to hold the product, a negative prompt and CFG control.
Two habits: keep "text, watermark, logo" in the negative prompt so you are not cloning out invented packaging copy all evening, and reuse the same palette wording as the video prompts so the stills and the clips look like one shoot. For listings, generate at 1:1 and 3:4. If the brand is illustrated rather than photographed, Image Art handles painterly and prose-faithful work and Image Anime handles stylized.
What a product page costs
One product, three 5-second shots on Motion One (100 credits per 5 seconds), a second take on the reveal, and six listing stills:
- Clips — 3 × 100 = 300
- Second take on the reveal — 1 × 100 = 100
- Stills — 6 × 10 = 60
Total 460 credits, about $4.60 at the entry pack rate of $10 for 1,000 credits. A twenty-product catalog is 20 × 460 = 9,200 credits, which fits inside Studio ($149 for 20,000 credits) with room for a second pass, or takes two months of Creator ($49 for 6,000).
Want 1080p for the hero shot? Kling 2.5 Turbo is 120 credits for 5 seconds on Creator and up, so the same three shots become 3 × 120 = 360, and the product page lands at 360 + 120 + 60 = 540 credits. Want the spot to carry its own sound? Veo 3 Fast renders a fixed 8-second clip with native audio for 256 credits, so a three-shot spot with sound is 3 × 256 = 768 credits before stills.
Failed renders refund themselves automatically, so a bad batch costs time, not money.
Iterating without starting over
Every render is saved in your library with its full recipe. Remix reloads that recipe into the tool, which is how you re-shoot one product in a new palette without rewriting anything, and Animate turns a still you like into the source for an image-to-video clip. When the catalog gets big enough that clicking becomes the bottleneck, the same renders are available through the API — videos/generations is an async job you post and then receive on a signed webhook, which is exactly the shape a catalog pipeline wants. The video docs have the parameters.
FAQ
Do I need a studio photo of the product to start?
One clean photo is enough. Attach it to the product Element as a reference; with a single photo the render runs as image-to-video and animates the product you actually sell. More photos from more angles make the reveal shot steadier.
Which image model for listing stills?
Image One for photoreal product shots at 10 credits each. Image Art when the listing wants an illustrated or painterly banner, Image Anime when the brand is stylized. All three take negative prompts, CFG control and reference photos.
How long can a product clip be?
It depends on the engine and the plan. Motion One renders 5 or 10 seconds, Seedance 1.0 Lite 3 to 12, Seedance 2.5 from 4 to 30 on Creator and up. Your plan caps it too — 10 seconds free, 15 on Hobby, 20 on Creator, 30 on Studio and above. For ecommerce, 5 seconds per shot is usually the right answer anyway.
