Generate video from a text prompt alone with the Vidu Q3 Pro API — no image input, flagship quality, up to 1080p, 1-10 seconds.
The Vidu Q3 Pro API (video_generate.vidu_q3_pro_t2v_novita) is the flagship text-to-video mode: you supply only a text prompt and the Vidu Q3 Pro API renders the whole clip from scratch, no image asset required. Describe the subject, motion, mood, and camera, then optionally set an aspect ratio and duration. The Vidu Q3 Pro API supports 16:9, 9:16, 4:3, 3:4, and 1:1, a variable 1 to 10 second duration, resolution up to 1080p, and an optional generated audio track per request.
Pricing on the Vidu Q3 Pro API is $0.425 per generation — 15% below the official rate of $0.500. It uses one RouterBase key, no separate SDK or account, and the same JSON shape covers 200+ other models. Because the Vidu Q3 Pro API is async and OpenAI-compatible, you POST /v1/images/generations with the model and a prompt, then poll GET /v1/images/generations/{id} until status=success. Teams reach for the Vidu Q3 Pro API for no-asset prototyping, storyboards, and ad variants, where the 15% saving compounds at scale.
