Vidu Q3 Pro Text to Video: Scenes with Sound and Cuts
Last verified: October 19, 2026
Vidu Q3 Pro is strongest on short narrative scenes: comic-drama beats, cinematic shots, episodes of a short series and story-led ads, where continuity and timing matter as much as the look of the frame. In text-to-video, Q3 Pro generates sound in sync with the picture and can split a clip into separate shots. That means a written scene can come back with its voices, effects and cuts already in place.
What you gain is fewer steps between script and edit. Vidu Q3 generates sound and picture together inside the model instead of adding audio afterward, and ShengShu positions it for animation, short drama, film production and other narrative formats. So your prompt works less like an image caption and more like a shot list with a sound column.
The form sticks to the settings that shape a scene: the prompt, the clip's length, its resolution and frame shape, and whether sound is generated. Write the scene, set those, and play each result with its audio before you download it. The soundtrack is part of the take, so check it as carefully as the picture.

Prompting Tips for Better Vidu Q3 Pro Videos
Write Camera Moves and Shot Sizes into the Prompt
Vidu Q3 is built for cinematic camera control, so treat the camera as part of the script. Name the shot size, the move and where it ends, for example 'low-angle medium shot, slow crane up to a wide of the valley', and give each shot one main move so the directions don't compete. Pick Aspect Ratio with the move in mind: a sideways track suits a wide frame, and a tilt up a standing figure suits a tall one.
Time the Action to the Clip Length
Vidu Q3 supports detailed control over camera language and rhythm. To use the rhythm side, say when things happen. Write the action in order (first, then, finally) and match the number of beats to the Video Duration you chose: one clear action for a short clip, a build and a payoff for the longer settings. A pause in the prompt, such as 'she waits a beat before answering', is part of the timing too.
Describe the Visual Style in Words
Vidu's separate style preset has no effect on Q3 models, so describe the look in the prompt itself. Start with the medium and finish (live action on 35mm film, manga-style cel animation, paper-craft stop-motion), then add lighting and palette. If several clips need to match, repeat the same style wording in every prompt.

Choosing Between Vidu Q3 Pro and Vidu Q3 Turbo
How Q3 Pro and Vidu Q3 Turbo compare on the points Vidu documents for both text-to-video models.
| Criterion | Vidu Q3 Pro | Alternatives | Best For |
|---|---|---|---|
| Generation speed | In Vidu's own comparison of its two Q3 text-to-video models, Q3 Pro is the slower one to generate. | Vidu Q3 Turbo is documented as generating faster than Q3 Pro. | If turnaround matters more than anything else, Vidu Q3 Turbo is the documented quicker option; if you are working with the controls here, Q3 Pro is the model they run, so allow a little more time per take. |
| Sound generated with the video | With Generate Audio on, Q3 Pro returns video with sound that includes dialogue and sound effects. | Vidu Q3 Turbo accepts the same audio-video generation setting, which Vidu documents for its Q3 models. | Sound is no reason to pick one over the other, since both Q3 models are documented to generate it with the picture, so decide on speed instead. |
| Output resolution | Q3 Pro's Resolution setting offers the same three tiers Vidu documents for the model, up to full HD. | Vidu Q3 Turbo is documented with the same three tiers, also up to full HD. | Picture size is the same for both models, so it shouldn't drive the choice; pick the tier based on where the video will be shown. |

Frequently Asked Questions
Can Vidu Q3 Pro handle a conversation between two or more characters?
Yes. Vidu Q3 supports natural conversations between several people. Give each speaker a short visual description the first time they appear, attach every line to one of them, and keep lines short so each has time to land within the clip.
Which languages can characters speak in Vidu Q3 Pro videos?
Vidu lists English, Japanese and Chinese as the languages for Q3's video output. Write each spoken line in the language you want to hear and name the language next to the line. Keep Generate Audio on so the line is voiced.
Does Vidu Q3 Pro add music, or only dialogue and sound effects?
Vidu lists background music among Q3's capabilities, along with sound effects and multilingual dialogue. Here, the whole soundtrack comes through the Generate Audio switch, so shape it in the prompt: name the kind of music and when it should come in, or ask for no score if you plan to add your own.
Does Vidu Q3 Pro render full HD natively?
Yes. Vidu lists native full-HD rendering among Q3's capabilities, and the top option in Resolution is full HD.
What makes one generation cost more than another?
The credit cost of a run is calculated from the options you choose and shown above the Generate button once you're signed in. Three settings change it: Video Duration, Resolution and Generate Audio. Enhance Prompt suggestions don't use credits.
