Native Ratio 2K/4K Delivery
Image-to-video keeps the source frame's proportions while rendering at 2K or 4K across 3–16 second durations.

Answers to Common Vidu Q4 Questions
Quick answers on reference limits, clip length, resolution and audio sync when you generate with Vidu Q4.
How many stills can one render take?
Up to fifteen. That lets you mix people, environments and visual styles inside a single generation.
Can I add my own voice recordings?
Yes — attach between zero and three clips to reproduce a character's voice with natural emotion and matched lip movement.
What is the maximum clip length?
Image-to-video produces 3 to 16 seconds, while reference-driven generation can build a sixteen-second sequence with multiple shots.
Which resolutions and ratios are available?
Renders arrive in 2K or 4K, and image-to-video preserves the aspect ratio of the picture you upload.
Is audio synchronized with the picture?
It is. Sound and video stay aligned, and mouth shapes follow any voice clip you supply.
