What Is Wan 2.5? Unlock Audio-Visual Synced Video Magic

At the 2025 Hangzhou APSARA Conference, Alibaba introduced the Wan 2.5 Preview model series, marking the first realization of audio-visual synced video generation and further empowering cinematic-level video creation.

Accurate Audio-Visual Sync

Wan 2.5 delivers precise audio-visual synchronization, generating sound effects, background music, ambient audio, and even ASMR based on prompts.

Wan 2.5 seamlessly aligns voice with on-screen visuals, perfectly matching lip movements and facial expressions while blending into the scene’s atmosphere. It also supports using audio as a reference input, enabling more accurate and context-aware video sound generation.

Native Multimodal Architecture

Unlike traditional models that handle only text or images, Wan 2.5 natively supports text, images, video, and audio as both inputs and outputs. This means creators are no longer limited to a single content format.

Through this multimodal approach, Wan 2.5 is able to understand and merge multiple content types seamlessly. Wan 2.5 processes all of these together, generating coherent audio-visual synced videos that align with the creative intent.

Longer Duration, Higher Quality

Wan 2.5 takes AI video generation to the next level with up to 10 seconds long at 1080p resolution and 24 frames per second, providing a cinematic feel in short-form content.

With this upgrade, the generated videos feature finer details and more complete content, allowing creators to produce scenes with richer storytelling, smoother motion, and more immersive visual experiences.

Enhanced Image Editing

Wan 2.5 offers powerful and versatile image generation and editing capabilities,including:

• Bilingual charts and tables: create clear, professional charts in both Chinese and English.

• Complex layouts: design multi-element graphics with precise arrangement.

• Artistic text effects: generate stylized typography for posters or banners.

• Flowcharts and architecture diagrams: visualize processes, structures, and systems seamlessly.
