Official examples from the model vendor: Alibaba.

Wan 2.7 Video is Alibaba's April 2026 umbrella video model, which picks its mode from the inputs you send. It covers text-to-video; image-to-video from a still, a first and last frame, a clip to continue, or audio that drives the motion; and prompt-based video editing. Output is 720P or 1080P in five aspect ratios, 2 to 15 seconds long (up to 10 for editing). Alibaba also offers a reference-to-video mode with separate subject images, clips and voices, but Jantaris does not expose it yet.

Best for

  • Animating a character in time with a voice or music file
  • Continuing a clip you already have
  • Editing a video by instruction, such as changing weather or outfits
  • Transitions between a first and a last frame

Prompting tips

  • Pair audio_url with one image to animate a still in time with the sound.
  • Sending video_url switches the request to editing; keep duration between 2 and 10 seconds.
  • Use negative_prompt for recurring problems, like "warped hands, flicker".
  • The default resolution is 1080P; drop to 720P for drafts. Prompts can be up to 5,000 characters.
