LUVI Creator is a web platform for generating video, images, audio and 3D with 223 AI models from 30 families, in one account paid in credits. It speeds work up with parallel runs, reusable references and workflows, and protects quality with prompting guides for 18 model families.
Kling 3 reads a shot as subject, movement and scene first, then camera, light and atmosphere: 60 to 100 words, one camera move, one action. The whole prompt is hard-capped at 2,500 characters and an overrun fails the submission before anything renders.
Write Veo 3.1 prompts camera first: cinematography, subject, action, context, style. Put dialogue, effects and ambience into the shot, and switch on Audio Generation, which is off by default on LUVI. Veo 3.1 Lite has no audio. Clips start at 800 credits for eight seconds at 720p.
Seedance 2.5 reads integer-second timestamps, typed audio channels and one camera move per shot. Most bad results come from prompting it like Seedance 2.0. Here is the structure that works, taken from the guide we run inside LUVI.
All three generate picture and sound in one pass, and all three read a prompt differently: H3 wants a fielded document, Omni wants a caption with a continuity clause, Wan wants an additive formula. Prices, limits and the one rule that breaks each of them.
A phone photo of a bottle becomes a clean studio still with Nano Banana Pro, then a five-second clip with motion and sound on Seedance 2.5 — wired as one workflow, estimated before it runs, from about 3,200 credits.
LUVI shows a credit estimate before every generation and charges you when the result arrives. Since September the charge is settled against the provider's real bill — capped at the estimate, never above it. What changed, what we measured, and why one model dropped from 15 credits to 7.
iPhone HEIC photos used to fail in Chrome, WebP confused half the models, and one library's browser decoder took 27 seconds on a 12-megapixel shot. So we moved the conversion to the server and made one rule: every image is stored as JPEG or PNG, colour profile and orientation intact.
