Vidu Q3 Pro treats a single generation like a short film, cutting between scenes on cue while keeping characters lively and their motion tied to synced, fitting audio.
With Vidu Q3 Pro on Pollo API, developers can add text-to-video and image-to-video generation to their products, controlling scene flow, clip length, and start-to-end framing per request.
Key Features of Vidu Q3 Pro API
Intelligent Scene Switching
Move between distinct settings within one clip, changing location, angle, or moment while keeping the same subject and narrative thread consistent across cuts.
Synchronized Generated Audio
Generate natural-sounding audio matched to on-screen action, so footsteps, ambience, and motion land in time without a separate sound pass afterward.
Start and End Frame Control
Feed a first and last image to build the motion between them, creating predictable openings and endings for transitions and transformation shots.
Human-Like Character Motion
Maintain believable gestures, gaze, and weight shifts so conversational and performance clips feel alive rather than stiff or floaty across the sequence.
Extended Range and Detail
Generate clips that run well past a single beat and render at up to 2K, providing room for longer story sequences and detail-heavy shots in one generation.
Use Cases of Vidu Q3 Pro API
Multi-Scene Story Clips: Generate short narratives across two or three settings in one clip for storytelling and trailer-style tools.
Talking Character Content: Produce expressive characters with natural gestures and synced audio for explainer, mascot, and conversational video tools.
Transformation Sequences: Use a first and last frame to animate a controlled change, such as a sketch resolving into a finished illustration.
Audio-Synced Shorts: Create short videos with synchronized sound and motion without manually pairing footage with a soundtrack.
Image-Led Animation: Turn a single still into motion, optionally ending on a chosen tail image to steer where the shot lands.
Localized Ad Variants: Render the same concept in widescreen, vertical, and square formats for different ad placements.
Longer Narrative Sequences: Build extended clips that maintain subject and story continuity across scene changes for episodic and serialized content.

Generate and Retrieve: Submit the task, poll the returned task status, and download the finished video once processing succeeds.
Prompting Best Practices for Vidu Q3 Pro API
Write prompts like a shot list. Name each scene in order, describe what changes at every cut, and note the character action and mood so scene switching stays coherent.
A Simple Prompt Formula
Scene 1 subject and action + transition or cut + Scene 2 setting and change + character gesture or emotion + audio cue + framing and style
What You Should Notice
Order Your Scenes: State scenes in sequence so the model knows when to cut and what carries over between them.
Anchor The Character: Describe the same subject in each scene to keep identity stable across switches.
Direct The Motion: Name gestures, gaze, and pace so character movement reads as intentional, not idle.
Cue The Audio: Mention sounds you want, since fitting audio is generated alongside the visuals.
Set The Endpoints: When using start and end frames, describe how the shot should travel between them.
Example Prompts
Two-Scene Narrative
"A street-food vendor flips noodles over a roaring wok as steam rises, then the shot cuts to a customer at the counter taking the first bite and grinning. Sizzling and market chatter fill the audio, warm handheld framing."
Sketch-to-Art Transformation
"Begin on a rough pencil sketch of a koi fish, then animate ink and color flooding in until it becomes a finished watercolor that ripples gently. Soft brush sounds and quiet ambience, steady centered framing, illustrated style."
Expressive Character Moment
"A puppet-shop owner leans over the counter, eyes lighting up as she winds a tiny music box and holds it out, mouthing a few words with a warm smile. The music box melody plays, cozy shop lighting, medium shot."
Scene-Switching Travel Beat
"A quiet harbor at dawn with boats swaying, then a cut to the same coastline at midday with gulls circling above the pier, ending on lanterns glowing at dusk. Water, wind, and distant bells in the audio, wide framing."
