Key Features

One Pass Audio Video Sync

Wan 2.5 Preview generates voice, lip sync, and ambient sound together with the video in a single run. Everything stays aligned from start to finish, cutting out the entire post production audio step.

Multilingual Voice Generation

The model handles voiceover in English, Chinese, and several other languages without losing sync quality. It supports dialect variations and accent styles so characters speak naturally in the language you choose.

Video Extend for Longer Clips

Take a short clip and stretch it with the video extend feature. Wan 2.5 keeps motion, style, and audio consistent as it adds new frames, so there are no visible cuts or quality drops.

Smooth Wide Range Motion

From subtle facial expressions to fast action sequences, movement stays stable and realistic across every frame. Large camera sweeps and quick subject motion look fluid rather than jittery.
