Vidu Q4 Preview (Reference to Video)
Vidu Q4 Preview reference-image to video. Supply 1-15 reference images via image_urls and refer to them in the prompt as @1, @2, … in array order; the model keeps those subjects consistent across the video. Optionally add up to 3 reference audio clips via ref_audios to guide voices and dialogue. Output includes a native audio track and goes up to 4K.
This model only accepts image_urls. For first-frame image-to-video use viduq4_preview — passing image_url or image_end_url here returns an error.
Pricing — per second of generated video, in tokens (USD at $0.02/token):
| resolution | tokens/s | USD/s |
|---|---|---|
| 540p | 2.925 | $0.0585 |
| 720p | 6.175 | $0.1235 |
| 1080p | 7.8 | $0.156 |
| 2K | 12.35 | $0.247 |
| 4K | 25.35 | $0.507 |
The price is the same for both Vidu Q4 Preview models and does not depend on the number of reference images or audio clips, or on generate_audio.
Example: an 8s 720p video costs 49.4 tokens (= $0.988).
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated video.
