The Problem

AI Rap Video Generator is a web tool that creates a short rap clip by animating two uploaded photos. Users provide one front‑facing portrait per performer, select a stage layout, and either upload a rap audio file or let the Seedance model generate a short rap from a text topic for pets or cartoon characters. The system runs the Wan 3.0 model for real people, which follows the supplied audio and a built‑in motion clip to drive mouth movements and gestures, while Seedance 2.0/2.5 produces original lyrics and voice for non‑human subjects. Video length can be 5, 8, 10, 12 or 15 seconds and output resolutions range from 480p to 1080p depending on the model; aspect ratios include 16:9, 9:16, 1:1, 3:4 and 4:3. Credits are deducted before generation and refunded automatically if the job fails. The result is a downloadable MP4 without watermark, stored privately and accessible via short‑lived links.
