Alibaba Tongyi Wanxiang 2.7 video-edit edition. Purpose-built for video-rewriting workflows — feed in a source video plus a text instruction (and up to 4 optional style reference images), get back a new video with style transfer / content replacement / full rewrite. Unlike T2V/I2V, VideoEdit requires video_urls and operates on “reworking an existing video”. Billed by resolution, with linear scaling by source-video duration.
Other tiers in the Wan 2.7 family (T2V / I2V / R2V) are not yet available; please contact sales if you need them.

Pricing

720P$0.07055 / sec

VideoEdit is billed by output-video duration; when duration=0 follows the source video, billing is based on the source-video duration.
