The Wan text-to-video models generate videos from text, images, and audio input. wan3.0-video supports up to 30 seconds, adaptive aspect ratio, smart duration, 480P/720P/1080P resolution, audio toggle, reference audio, and reference files and web links.
Shot 1 The sequence opens with an extreme long shot. The camera starts at a low angle near the ground and moves forward across the grassland while tilting upward. As the camera rises from ground level to a slightly elevated position, the cheetah enters the frame from the left. This shot establishes a clear spatial relationship by placing the cheetah and the fleeing antelope on the same path. Shot 2 The camera descends to a near-ground level and tracks to the right, parallel to the cheetah. The cheetah is kept consistently left of center, which creates a continuous lateral shift in the background. For a period, the camera movement remains steady to enhance the sense of speed and spatial continuity. Shot 3 While still moving to the right, the camera executes a slight arc along the inside of the cheetah's path. This movement creates a subtle orbiting effect in the frame as the camera continues to follow the subject. Shot 4 The camera gradually slows its lateral movement and becomes relatively stable while simultaneously zooming in. This action narrows the focus to the shrinking distance between the cheetah and the antelope. Shot 5 The camera again moves forward and slightly downward, hugging the ground to close the distance between the two animals. The shot stops at the critical point just as the cheetah's forelimbs are about to reach the antelope's hindquarters, which creates intense pressure and tension. This action is synchronized with a crescendoing symphonic score, a densifying drumbeat, and the sounds of wind and footsteps that drive the rhythm. In the final moment, the music volume drops, leaving only ambient and rhythmic sounds to create a brief pause.

Supported models: wan3.0, wan2.7, and wan2.6 series.Description: Automatically switches between shots — for example, from a wide shot to a close-up. Ideal for music videos and cinematic narratives.Parameters:
wan2.7: The shot_type parameter is not required. Describe shot structure in the prompt using natural language, such as timestamps to define shots. If the prompt does not contain shot structure descriptions, the model analyzes semantics and automatically determines whether to generate a single-shot or multi-shot video.
wan2.6: The shot_type parameter must be set to "multi", and the prompt_extend parameter must be set to true to enable intelligent rewriting to optimize shot descriptions.
Input prompt
Output video (wan3.0)
A vision of harmony between future technology and nature. Shot 1 [0-2s]: Wide shot of an aerial garden in a futuristic city, floating plants swaying gently in the breeze. Shot 2 [2-4s]: A robot gardener carefully trims plants with precise, graceful movements. Shot 3 [4-7s]: Sunlight streams through a transparent dome, illuminating the entire garden and showcasing the perfect fusion of technology and nature. Shot 4 [7-10s]: The camera pulls back to reveal the grand scale of the entire futuristic city, with the aerial garden as just one part of it.
This is a martial arts film clip centered on a hardcore duel. On a stone clearing under the midday sun, two men charge at each other. One strikes with his palm, but his opponent spins and blocks with his arm, the impact kicking up dust from the ground. They then exchange rapid punches and palm strikes in a tight space. One leaps into the air for a series of heavy kicks, forcing his opponent to cross his arms to block and slide back several meters, leaving clear white marks on the stone surface. Finally, they stand apart, breathing heavily and locking eyes. The scene presents a realistic action texture with sharp lighting, creating a tone that shifts from powerful explosion to a tense standoff.

Supported models: wan3.0, wan2.7, wan2.6, and wan2.5 series.Description: Characters in the video can "speak" or sing, with mouth movements matching the audio. For more examples, see Video audio generation.Parameters:
Provide an audio file: Set audio_url. The model synchronizes mouth movements with the audio file.
Automatic dubbing: Without an audio_url, the model automatically generates audio-enabled video by default — adding background sound effects, music, or voices based on the visual content.
Input example
Output video (audio-enabled video)
Input prompt: Shot from a low angle, in a medium close-up, with warm tones, mixed lighting (the practical light from the desk lamp blends with the overcast light from the window), side lighting, and a central composition. In a classic detective office, wooden bookshelves are filled with old case files and ashtrays. A green desk lamp illuminates a case file spread out in the center of the desk. A fox, wearing a dark brown trench coat and a light gray fedora, sits in a leather chair, its fur crimson, its tail resting lightly on the edge, its fingers slowly turning yellowed pages. Outside, a steady drizzle falls beneath a blue sky, streaking the glass with meandering streaks. It slowly raises its head, its ears twitching slightly, its amber eyes gazing directly at the camera, its mouth clearly moving as it speaks in a smooth, cynical voice: 'The case was cold, colder than a fish in winter. But every chicken has its secrets, and I, for one, intended to find them '.Input audio:

Q: What code changes are needed to upgrade from wan2.7 to wan3.0?
Model name: Change model from wan2.7-t2v-* to wan3.0-video.
Remove prompt_extend: wan3.0 does not support the prompt_extend parameter. Remove this field.
Extended duration: wan3.0 supports up to 30 seconds (wan2.7 supports up to 15 seconds). Set duration to an integer between 2 and 30.
New file and web input: wan3.0 supports passing type: "file" (docx, ppt, pdf, etc.) or type: "link" (public web URL) in input.media. The model automatically understands the content and generates a video. These two types cannot be used simultaneously.
Q: The videos generated in the console have a watermark. How do I remove it?
The video generation page in the Model Studio console does not provide a watermark switch, so you cannot disable the watermark in the console.
When you call the model through the API, set watermark to false to generate a video without a watermark.
If you omit the watermark parameter, the API adds a watermark by default. The sample code in this topic passes watermark=true; change it to false to remove the watermark.
