Wan 2.5
Alibaba's open-source AI video model that generates cinematic 1080p video clips with fully synchronized audio — including dialogue, ambient sound, and music — all in a single step.
Wan 
WaveSpeed Open-source video generation with synchronized audio
Wan 2.5 is an open-source AI video generation model developed by Alibaba's DAMO Academy. It produces video clips up to 10 seconds long at resolutions up to 1080p, and generates synchronized audio — including dialogue with lip-sync, ambient sound effects, and background music — alongside the visuals in a single generation step. The model accepts text prompts, still images, audio tracks, or existing video clips as input, and supports cinematic controls such as camera movement types, lighting styles, and depth of field specified directly in the prompt.
Wan 2.5 is designed for content creators, filmmakers, advertisers, and developers who need video output with accompanying audio without separate post-production workflows. It supports prompts and generated dialogue in at least 8 languages, and offers 480p, 720p, and 1080p as standard output resolutions with native 4K available in preview. Compared to its predecessor Wan 2.2, this version doubles the maximum video duration from 5 to 10 seconds, raises the standard resolution from 720p to 1080p, and introduces the audio generation system as an entirely new feature.
What Wan 2.5 supports
Image-to-Video
Animates a source image into a video clip up to 10 seconds long at resolutions up to 1080p. Accepts image URLs as direct input.
Text-to-Video
Generates video clips from natural language prompts, supporting cinematic controls like dolly shots, crane movements, and color grading specified inline.
Synchronized Audio Generation
Produces dialogue with lip-sync, environmental sound effects, and background music simultaneously with the video in a single generation step.
Multilingual Prompting
Accepts prompts and generates dialogue across at least 8 languages, enabling localized video content without separate translation workflows.
Seed Control
Accepts a numeric seed value to make generations reproducible, allowing consistent outputs when iterating on a prompt.
Resolution Selection
Supports 480p, 720p, and 1080p as standard output resolutions, with native 4K available in preview, configurable via numeric parameters.
