Alibaba WAN 2.5 — Video Extend Model

Alibaba WAN 2.5 is an advanced video extension model available on Alibaba Cloud DashScope, designed to extend or complete video clips while maintaining perfect motion continuity, style consistency, and A/V synchronization. It supports custom durations from 3 to 10 seconds and resolutions up to 1080p.

✨ Why it’s special

• Seamless extension: Extends videos naturally — no abrupt cuts or looping artifacts. The motion flow and scene lighting stay coherent frame to frame.
• Flexible duration control: Choose any target length from 3 s – 10 s (3, 4, 5, 6, 7, 8, 9, 10 s all supported).
• One-pass A/V sync: Automatically aligns audio and mouth movements, ensuring natural speech and rhythm without manual editing.
• Multilingual friendly: Supports prompts in Chinese and English for synchronized video generation with accurate lip-sync.
• Custom audio option: You can upload your own audio (music or voice) or let the model generate one for you — plug-and-play.
• Lightweight and affordable: Built for creators and teams who need fast, consistent, and cost-effective video outputs.

• Marketing teams: Produce multiple ad variations from a single core clip — faster, cheaper, consistent.
