Three things to keep in mind
- Choose an input mode that matches your assets.
- Review the whole clip, not a thumbnail.
- Check this site’s current settings and availability.
Compare documented features before judging the result
Q4: image and reference video
Vidu’s Q4 page separates image-to-video from reference-to-video. It describes character, scene and style references, alongside voice guidance and scene effects. These are official Vidu features, not a statement that every option is integrated here.
Q3: scenes with native audio
Vidu presents Q3 around generating visuals and sound together, with narrative use cases and camera direction. If sound matters to a project, review speech, timing and ambient audio as well as the image sequence.
Access on the current ViduAI site
Choose Q4 or Q3 in the workspace, add text or image references, and adjust the clip settings for your project.
Start with the video you actually need
A useful Vidu AI review begins with an input and a deliverable. A product shot, character dialogue and moving illustration put different demands on references, motion and sound. Decide which details must remain exact before comparing a model name.
For a product scene, list the geometry, label and lighting that must remain recognizable. For a character shot, consider the face, clothing and expression. For a landscape, focus on camera drift, environmental movement and the ending frame. A generic beautiful example does not establish that your own material will behave the same way.
Use the same source assets and a short, unambiguous prompt for a comparison. Change one instruction at a time. Keep the first result and subsequent revisions so you can judge the whole process rather than selecting only a successful frame.
Q4 and Q3: compare their documented emphasis
The official Q4 page emphasizes visual references and image-led scenes, while the official Q3 page emphasizes audio and narrative direction. These are vendor descriptions, not benchmark scores from this website.
The Q4 page lists up to 15 image references, up to three voice references and a maximum of 16 seconds with 2K/4K options. The Q3 page describes integrated audio and video and a maximum of 16 seconds. Read the official workflow requirements before assuming the same setting exists on another website.
The current ViduAI workspace provides its own Q4/Q3 workflow entrances, 4–15-second settings, 480p/720p and optional generated audio. It accepts text, first/last frames or up to nine image references. Voice-file and video-reference uploads are not open here.
A practical quality-review checklist
Review the complete clip rather than a preview thumbnail. Continuity errors often appear between otherwise convincing frames, especially during contact, turns and camera movement.
- Does the subject remain recognizable from beginning to end?
- Are hands, faces, product labels and object proportions stable?
- Does the camera follow the requested movement without unexpected cuts?
- Is the action complete within the selected duration?
- If audio is present, are speech and scene sounds clear and appropriate?
- Can the clip be used in the intended edit without hiding major errors?
Prompt revisions that are easier to evaluate
A good revision explains one change. If the subject moves too much, reduce the gesture before changing the camera, lighting and duration at the same time.
For example, replace “dramatic cinematic movement” with “the character turns the head slightly toward the window; the camera stays locked.” The instruction identifies the moving element and the stationary one. When appearance is essential, use a clear image input instead of describing every feature from memory.
In reference mode, assign each picture a purpose. A product image, character design and environment reference should not compete to define the same object. Fewer coherent references can be easier to direct than a collection of contradictory examples.
Who this workflow can suit
Image-led preparation suits people who already have assets. Text-led preparation suits early ideas. Reference-led preparation suits a scene that combines a subject with a particular setting.
Marketing teams can prepare product-scene briefs, illustrators can plan restrained animation and storytellers can organize separate short scenes. A longer narrative still needs editing, sequencing and consistency review. Do not expect a short-video workflow to replace the entire production process.
Choose an entrance for your source material
| Your input | Workflow | Prepare first |
|---|---|---|
| A written idea | Text to video | Subject, setting, action and camera |
| An opening image | Image to video | First frame, motion and optional last frame |
| Several visual references | Reference to video | Reference roles and a coherent scene brief |
Frequently asked questions
Which is better, Q4 or Q3?
The official pages emphasize different workflows. Compare the exact input and output options available on your service, then test the shots your project needs. This overview does not establish a quality winner.
Where can I check the official specifications?
Use Vidu’s model pages and API documentation. Specifications on a third-party service may differ because it exposes a different integration.
Can I save a scene before generation is available?
Yes. Prepare the prompt, selected images and settings, then save the draft. Saving is separate from submitting a video-generation task.
Which settings does the current workspace offer?
The current video workflows offer 4–15 seconds, 480p or 720p, a supported aspect ratio and optional audio. Reference mode accepts up to nine images; first/last-frame mode is separate.
Are the displayed examples generated here?
No. Displayed media illustrates creative uses. It is not a tested result from this service or evidence that generation has been activated.
