The first time Ori “saw” the luxury bag photos, she did what most AI does when it’s bored: she tried to get creative. A zipper multiplied. A pocket teleported. A mysterious extra logo appeared like an uninvited party guest.
My client was selling luxury bags, and we were building ecommerce video from a static product image library—clean, premium, Apple-like minimal. The goal wasn’t cinema. It was conversion: high-quality product demos that feel expensive, consistent, and trustworthy.
So we treated every prompt like a contract. We added hard constraints. We removed ambiguity. We refined until the bag stopped shape-shifting.
This article is the proof: the exact workflow and the well-crafted prompts that turned product photos into scalable video marketing—without redesigns, random items, or weird brand accidents.
What I Learned:
Here’s the uncomfortable truth about ai video generation: the model doesn’t “know” your product is sacred. If your prompt is vague, it will “help” by improvising—changing stitching, inventing pockets, “improving” materials, or tossing in recognizable logos on props. In ecommerce, that’s not creativity. That’s a return request.
So I started thinking of a prompt as three layers:
- Creative direction (what the viewer should feel)
Premium, professional product, minimal, high-impact. Your target audience should immediately clock: luxury, clarity, confidence. - Shot plan (what the camera should do)
One motion per shot. Stable frame. Controlled camera angles. Defined video length. Defined aspect ratio. Defined visual style. This is where a good prompt becomes repeatable video production. - Hard constraints (what must never change)
This is the anti-chaos layer. The “don’t redesign my bag” clause. In our case, the hard constraints were the difference between “nice” and “usable.”
That’s why I now build every ai prompt with a workflow:
The Ecommerce AI Video Prompt Workflow
Step 1: Choose a single goal per video
“Engaging video” is not a goal. A goal is: Show compartments clearly, sell the zipper quality, prove it fits a laptop, make a 30-second video for TikTok, create a Reel montage for retargeting, or generate a promotional video for a product or service launch.
Step 2: Anchor with references (your product image set)
Static images are your guardrails. If you feed [REF_1] [REF_2] [REF_3] (hero angles + detail close-ups), you’re basically saying: “Don’t guess. Match this.” That’s how we kept a professional product consistent across frames.
Step 3: Write the prompt like a spec sheet
A good prompt names:
- background (white seamless / neutral gradient)
- lighting (softbox, soft shadow)
- motion (slow push-in, slide, match cuts)
- pacing (editorial timing, hold last 1 second)
- deliverable (aspect ratio, duration)
Step 4: Add the constraints block every time
This is the single biggest best practices move. It prevents brand damage and reduces iteration.
Step 5: Iterate and refine with intention
When the output is wrong, don’t just “try again.” Diagnose:
- Did the model redesign the bag? Strengthen constraints.
- Did it add props? Ban props and logos.
- Did it warp? Add “no morphing/warping.”
That’s how you refine without burning hours.
Step 6: Don’t stop at video—finish with caption + CTA
A video marketing strategy isn’t complete until you can ship it. I always generate a high-quality caption, subtitle ideas, and text overlays (when allowed) in the same pass. That’s how you make it actionable for marketing campaigns and content marketing.
This is where ChatGPT prompts become the glue: you use ChatGPT prompts to create scripts, product demo structure, and seo-optimized captions that match brand voice.
Applied SMB Use Case
Let’s recreate the exact use case: luxury bags + product photos → ecommerce ai video + caption + CTA.
The setup
You have:
- 6–10 product photos (hero angles, close-ups, interior shots)
- a clear target audience (commuters, business travelers, gift buyers)
- one offer (free shipping, warranty, limited drop, etc.)
Your objective:
- create video assets for TikTok, Instagram Reel, product pages, and ads
- keep visuals high-quality and consistent
- boost conversion with clear product demos
Step-by-step prompt package (copy/paste)
Below are the detailed prompts I used (templates). These are video prompts designed to prevent the two failure modes: bag redesign + random items/logos.
Use placeholders:
- [REF_1] [REF_2] [REF_3] = your product shots (anchors)
- [DURATION] = 8s / 10s / 12s
- [ASPECT] = 9:16 / 1:1 / 16:9
Universal “Hard Constraints” block (paste at end of every prompt)
CONSTRAINTS:
“Backpack must remain identical across all frames: same shape, stitching, zipper count, pocket layout, logo placement, materials, and color. Camera stable: no rotation, no angle drift, no zoom unless specified. Pure white studio background. Softbox lighting + soft shadow. No people, no hands, no text, no watermark. No logos on items (no Apple). No warping/melting/morphing. No added/removed pockets or zippers.”
1) Luxury Hero Rotation (8–12s)
PROMPT:
“[DURATION] luxury studio product video of a black KNOMO backpack on a pure white seamless background. Premium ecommerce style, Apple-like minimal. Create a smooth turntable rotation illusion (3/4 → front → side → back) with subtle parallax. Gentle highlight sweep across zippers and fabric, soft shadow under bag. Bag centered, constant scale, no cropping.”
Paste CONSTRAINTS
NEGATIVE (if supported): “no extra straps, no new pockets, no pattern changes, no background props”
2) Feature Callout Tour (10–15s)
PROMPT:
“[DURATION] studio product video on white seamless. Start with hero shot of the backpack, then cut to close-ups that showcase features. Add minimal animated callout lines and short labels (max 2–4 words each): ‘Laptop sleeve’, ‘Organised interior’, ‘Dual compartments’, ‘Trolley sleeve’. Camera moves are slow push-ins only. Clean editorial pacing.”
Paste CONSTRAINTS
(If you don’t want text overlays: remove callouts and say “no text overlays.”)
3) Packing Demo (Most reliable) — Open bag + items appear (8–10s)
PROMPT:
“[DURATION] premium tabletop packing demo on white seamless, slight top-down angle. Start matching [REF_EMPTY_INTERIOR]. End matching [REF_FULL_INTERIOR] exactly. Only the items change: they appear/settle step-by-step into the correct compartments with gentle easing (no flying). Hold final packed layout for the last 1–1.5 seconds for readability.”
Paste CONSTRAINTS
Optional add-on: “Items must be plain/unbranded and match the final arrangement.”
4) Stop-Motion Fill (Super safe) — Pop-in steps (10s)
PROMPT:
“[DURATION] stop-motion style video on white seamless, locked camera. Start matching [REF_EMPTY]. Items appear in discrete pop-in jumps (2–3 jumps per item), not smooth motion. Step order: laptop → notebooks → sneakers → bottle/cable. End matching [REF_FULL] and hold.”
Paste CONSTRAINTS
If the model freelances: make 3 intermediate images and add them as anchors.
5) Commute → Travel Proof (8–12s)
PROMPT:
“[DURATION] mini story in clean studio style. Shot 1: hero backpack (confidence). Shot 2: open interior with laptop (work ready). Shot 3: trolley sleeve on suitcase handle (travel ready). Use match cuts or clean wipes (not morphing). Subtle push-ins, softbox lighting, white seamless.”
Paste CONSTRAINTS
6) Catalogue Montage (6–10s)
PROMPT:
“[DURATION] rapid premium catalogue montage. Each shot lasts 0.7–1.2 seconds with one simple motion (push-in or slide). White seamless background, consistent scale, crisp cuts. End on hero shot for 1 second.”
Paste CONSTRAINTS
7) “Floating Product” Gradient Ad (8–12s)
PROMPT:
“[DURATION] modern floating product video. Cut out the backpack cleanly from the background and place on a soft neutral gradient. Add subtle floating motion + soft shadow ‘breathing’. Slow highlight sweep on zippers. Keep it minimal, premium, no props.”
Paste CONSTRAINTS
8) “Macro Material ASMR” (6–10s)
PROMPT:
“[DURATION] macro close-up sequence of premium details: zipper pulls, stitching, fabric texture, interior lining. Cinematic softbox lighting, slow push-ins, shallow depth-of-field look. No scene changes, no hands, no text. End on hero shot.”
Paste CONSTRAINTS
The finishing move: generate captions + CTA with ChatGPT
Once your ai video output is solid, use ChatGPT prompts for video marketing to generate on-brand copy.
ChatGPT prompt (caption + CTA + subtitle ideas):
“Write a high-quality caption for a luxury backpack product demo. Brand voice: minimal, confident, premium. Target audience: commuters + frequent travelers. Include 1 subtle CTA and 3 subtitle options (short). Mention: laptop sleeve, organised interior, trolley sleeve. Keep it TikTok/Reel friendly.”
Example AI output (what you want):
- Caption: “Designed for the commute. Built for the gate. A place for everything—without the bulk. Tap to explore.”
- Subtitle options: “Work. Travel. Repeat.” / “Packed, but polished.” / “Luxury meets function.”
- CTA: “Shop the drop.”
That’s leveraging video + writing effective prompts to create content that ships fast—and looks expensive.
Closing Reflection
After the fifth round of iteration, Ori stopped trying to “improve” the bag. The silhouette stayed locked. The stitching behaved. The product image anchors finally acted like gravity.
And that’s the real lesson: video marketing isn’t about magic tools like Sora or Veo. It’s about control—clear direction, constraints, and a repeatable workflow that turns product photos into video content you can actually run in ads.
Next experiment, I’m teaching Ori to generate UGC-style testimonial scripts (without getting cringe), then pairing them with clean product demos for a split-test: premium polish vs. human voice. Same product. Two worlds. One conversion scoreboard.
