WAN 2.7 Video AI動画生成

WAN 2.7 Video is Alibaba Cloud's flagship text-to-video model and the most versatile single model on FlyAIgh in terms of mode coverage. It supports all four input modes — text-to-video, image-to-video (first or last frame), reference-to-video (up to 4 reference images) and video editing (modify an existing clip with a text instruction) — under one model id, with the platform routing automatically based on what you provide.

The headline capability is multi-shot narrative. Where most video models produce a single continuous shot, WAN 2.7 can compose multiple shots within a single generation — transitioning between camera angles, locations or story beats. This makes it particularly strong for ad concepts, short-form storytelling and scene-driven content where a single static framing isn't enough.

Clips run from 2 to 15 seconds in 1-second increments across five aspect ratios (16:9, 9:16, 1:1, 4:3, 3:4). Output resolution is 720p or 1080p — pick 1080p for hero shots and final deliverables. Pricing is 8 credits per second — 40 credits for a standard 5-second clip, 80 for 10 seconds.

WAN 2.7 Video sits in the same family as WAN 2.7 Pro (the image-side flagship). Both share Alibaba's underlying generation stack but specialize for their respective modalities. The video model adds a few unique parameters: `prompt_extend` (the model rewrites your prompt for better narrative coherence) and `audio_url` (drive the video to a supplied audio track for music-synced output, on the text-to-video path).

WAN 2.7 Video is particularly strong at multi-shot composition, narrative pacing and Chinese-cultural visual aesthetics. It is weaker than VEO 3.1 Quality for ultra-fine textural detail and weaker than Sora 2 Pro for photorealistic faces. Pick WAN 2.7 Video when you need narrative breadth or full mode coverage in a single generation; pick the specialists when you need maximum fidelity in a single shot.

On FlyAIgh, WAN 2.7 Video runs through Alibaba Cloud Bailian with no separate Alibaba account, API key or Mainland China registration required.
