Choosing an AI Video Generator: Buy a Deliverable Workflow + Free Product Video Brief and Acceptance Sheet (Word)
For a real product campaign, judge whether the product stays accurate, mistakes can be corrected and the finished clip fits your delivery requirements. Generative footage can help explore scenes, mood and transitions. Use verified source assets for packaging, precise specifications and demonstrations of how a product actually works.
This is an official-information buying guide with an Allua trial framework, not a hands-on ranking of quality, speed or success rates. The comparison and ten-point template below are ready to use.
What to trial
Runway documents text-to-video and image-to-video in Gen-4.5. Test a simple camera move using an approved product image before attempting a complicated sequence. Firefly provides text- and image-led video generation with multiple model choices; record which model you select rather than treating every model as having identical terms. Luma separates Dream Machine subscriptions from API billing, so check the route you intend to use. Official sources: Runway documentation; Firefly video features; Luma subscription guidance.
Tool | Documented basis | Trial focus |
|---|---|---|
Runway | Text or image to video | Product consistency and camera control |
Adobe Firefly | Multi-model video workspace | Model, editing fit and terms |
Luma Dream Machine | Web subscription separate from API | Usage, generation cost and revisions |
Give every tool the same brief
Imagine a 500 ml insulated cup and a 15-second vertical advertisement for commuters. The desired action is a product-page visit. Supply front, side and detail photographs, with the cap, logo, colour and dimensions identified as fixed. Do not ask generated footage to prove leak resistance or insulation duration.
Allocate three seconds to the setting, eight to the product and a verified benefit, and four to branding and the next action. Hold the source material, shot objective and attempt limit constant. Record generation time, correction time and which outputs pass your criteria.
Example prompt: “Use the supplied product photograph as the sole reference. Preserve its proportions, lid, colour and mark. Move the camera slowly forward in a softly lit morning desk scene. Add no text, accessories or product features. Compose for a vertical crop.” Check the mark frame by frame; a prompt is not a guarantee.
Budget for usable shots
Cost per accepted shot = allocated software and generation spend plus correction labour, divided by accepted shots. For illustration, HK$300 in software and generation plus three hours at an assumed HK$250 per hour totals HK$1,050. Three accepted shots cost HK$350 each. These are hypothetical figures, not a vendor quote or measured result.
For a small 15-second product clip, Allua suggests planning HK$1,500–3,000 for briefing and storyboards, HK$2,000–5,000 for asset preparation and generation, and HK$2,500–6,000 for editing, captions, music and two revision rounds: HK$6,000–14,000 overall. Allow roughly 5–10 working days with usable photographs supplied. Filming, voiceover, additional rights and media spend are separate; do not count included package work twice.
