Vidu Q3 Text to Video

Vidu Q3 Text to Video is a specialized SandBase endpoint built to translate a written scene into a complete video without requiring any source media. It is most useful when teams need prompt-led scene construction, integrated audio, cinematic camera direction, and up to sixteen seconds of continuous action, with the route’s inputs defining a repeatable production contract instead of leaving critical delivery choices to an ad-hoc manual workflow.

Use this exact route when its input mode matches the creative asset already in hand: describe the visual or spoken result clearly, set only the controls that support the intended delivery, and keep the subject, action, environment, camera or performance direction internally consistent. The result is returned asynchronously as a downloadable media URL suitable for review, automation, or downstream finishing.

Highlights

• Prompt-first world building. Define subjects, setting, lighting, action, and visual treatment entirely in text when no approved source frame exists.
• Long-form shot design. A 1–16 second duration range gives actions and camera moves enough room to develop beyond a brief loop.
• Native audiovisual storytelling. Generated sound can include spoken lines, environmental ambience, and action-linked effects alongside the picture.
• Broad framing control. Ten aspect ratios and resolutions through 1080p support cinematic widescreen, feeds, square placements, and vertical stories.

Pricing

Billing follows the selected duration and resolution. The standard rate is $0.0700 per second at 360p/540p and $0.1540 per second at 720p/1080p.

When to Use

Prompt Guide

Lead with the main subject or source asset, then describe the intended action or transformation, environment, composition, camera or vocal delivery, lighting and mood. Keep instructions concrete and compatible; use the route’s explicit fields for duration, resolution, ratio, quality, voice, or reproducibility instead of burying those settings in prose.
