Vidu Q3 is useful to investigate when a shot needs sound as well as movement. Searches written as viduq3 refer to that model name. A short scene becomes easier to direct when the image, speaker and sound requirements are written together before you spend on the first generation.
What the official Q3 page documents
The official Q3 page describes combined video and audio, clips up to 16 seconds, camera and pacing control, multi-person conversation and English, Japanese and Chinese output. These are documented capabilities, not a measured guarantee of synchronization or continuity in every output. We did not run a paid Q3 test.
Vidu's homepage now also presents Q4. Keep the version recorded with your scene notes. A Q4 example or third-party plan cannot establish the limits of the Q3 operation you selected. Check whether your interface supports text, an initial image or additional references for that exact route.
| Requirement | Plan before generation | Review after export |
|---|---|---|
| Dialogue | One short line per named speaker | Words, pronunciation and correct speaker |
| Action | One legible event | Continuous movement and stable props |
| Camera | Framing and one planned move | No unintended cut or lost subject |
| Sound | Ambience and deliberate effects | Timing, intelligibility and unwanted music |
An original cafe scene with a timed brief
Use two fictional adults in a quiet cafe: Mara wears a rust coat and Jules wears navy. Keep both seated, with one plain mug each. The action is simply Mara sliding a folded note across the table. That gives the scene a visible event and two short lines without asking for a chase, costume change and camera cut in the same clip.
Landscape cafe shot at dusk, two original adult characters at a small table beside a rainy window. Mara in a rust coat sits left; Jules in navy sits right. First beat: Mara places a folded note on the table. Second beat: she slides it toward Jules and says, “You left this at the station.” Final beat: Jules looks at the note and says, “Then we still have time.” Keep the mugs stationary. Slow restrained push-in, no cut. Quiet rain outside and gentle room ambience, no music or subtitles.
This is an untested editorial prompt, not a supplied Q3 result. Choose a duration supported by your current settings and leave time between lines. If you use the full documented 16-second window, plan a short opening, a central exchange and an ending hold. The written beats are direction, not a promise of frame-exact compliance.
Separate the visual reference from speaker instructions
If your selected operation accepts an image, approve that image before animating it. Check which character sits on each side, what they hold and how much table space is available for the note. Record reference roles separately from dialogue so a wardrobe instruction does not accidentally become spoken text.
Keep lines short enough to hear once. Use speaker names consistently rather than switching between “the woman,” “character one” and a name. For a multilingual deliverable, choose one documented language for the initial test. Have a fluent reviewer check words and pronunciation instead of accepting speech because it sounds plausible.
Download the original cafe shot and audio review sheet
Review native audio through the whole clip
Listen with headphones and watch at ordinary speed before stepping through problem frames. Inspect where the voice starts, which character speaks, whether words overlap and whether the mug or note makes an unintended sound. A silent preview can hide the main reason a dialogue clip is unusable.
If the motion is good but a line fails, preserve the accepted visual reference and shorten that line. If the note changes shape or a hand passes through it, simplify the contact action. Change one constraint at a time so you know whether the revision solved the original failure.
Budget by the selected interface
Check the current Vidu plans and the charge displayed for your chosen operation. Website subscriptions, API billing and a reseller's credits are separate offers. We do not publish a universal Q3 price based on a testimonial or a different provider's allowance.
For a longer episode, prepare several short shots with a continuity sheet. Match coats, seat positions, prop placement and the previous shot's ending. Leave enough editing time to balance audio between shots. A 16-second generation limit does not define the length of the finished episode you assemble.
