Camera Language: Utilize standard cinematography terms to define camera movements. This gives you precise control over the final output.
Pan left/right: Horizontal camera movement.
Tilt up/down: Vertical camera movement.
Dolly in/out: Moving the camera closer to or further from the subject.
Orbital arc: A camera movement that circles the subject.
Crane up/down: Vertical camera movement on a crane.
Motion Modifiers: Use descriptive language to guide the flow and depth of motion.
Speed: Slow-motion, Whip-pan, Time-lapse.
Parallax: Create a sense of depth by describing the relative movement of foreground and background elements (e.g., "Foreground grass sways while mountains remain still").
Aesthetic Tags: Define the visual style of your video with precise descriptors.
Lighting: Volumetric dusk, harsh noon sun, neon rim light.
Color Grading: Teal-and-orange, bleach-bypass, Kodak Portra.
Lens/Style: Anamorphic bokeh, 16mm grain, CGI stylized.
Audio Elements: Describe the desired audio components of your video.
Dialogue: Include spoken words in quotation marks.
Sound Effects: Describe ambient sounds and specific sound events.
Music: Specify the genre or mood of the music.
Negative Prompting: Use negative prompts to exclude unwanted elements or characteristics from your video.
4. Example Prompts
Text-to-Video (T2V) Examples
Mountain Biking Scene
Prompt: A mountain biking trail through dense forest portrayed in a photorealistic 1:1 format. The POV follows a cyclist descending; leaves crunch, tyres hiss and friends shout encouragement off‑screen while birdsong and wind fill the soundscape.
This prompt generates a dynamic and immersive video that showcases Wan 2.5's ability to create realistic motion and a rich, layered soundscape. The model successfully interprets the POV camera instruction, creating a sense of speed and immediacy. The audio generation is particularly impressive, with a clear distinction between the different sound elements described in the prompt.
Anime Cliffside Scene
Prompt: A stylised anime cliffside scene shot vertically 9:16 where a samurai girl stands under a full moon; wind whips her cloak and ethereal choral music swells. She murmurs, “The journey begins,” as cherry‑blossom petals swirl in slow motion.
This example highlights Wan 2.5’s proficiency in generating stylized content. The model accurately captures the anime aesthetic, from the character design to the atmospheric elements like the full moon and swirling cherry blossoms. The lip-sync feature is also demonstrated here, with the character's mouth movements synchronized to the spoken dialogue.
Cyberpunk Hacker's Lair
Prompt: A stylised cyberpunk hacker’s lair shot in 9:16 vertical format. Glowing code and screens illuminate a figure; a robotic voice counts down “Initiate sequence…three…two…” while atmospheric synths drone and the hacker’s fingers blur.
This prompt demonstrates Wan 2.5's ability to create complex, futuristic scenes with intricate details. The model successfully generates the glowing code, multiple screens, and atmospheric lighting described in the prompt. The audio generation is also noteworthy, with the robotic voice and synth drone creating a tense and futuristic atmosphere.
Tranquil Forest Scene
Prompt: A slow dolly-in captures a tranquil forest at sunrise, dew glistening on mossy rocks as mist gently drifts between ancient trees. Sunlight beams pierce through the branches, casting moving shadows that dance with the shifting light. A gentle breeze stirs the leaves, causing subtle waves of motion in the canopy above. Tiny insects hover and flit near the forest floor, accentuating the sense of depth with parallax movement. Cinematic soft lighting and warm golden color grading enhance the peaceful atmosphere. The shot maintains smooth camera motion and natural scene dynamics, avoiding overexposed highlights or artificial motion artifacts.
This 10-second video showcases Wan 2.5's ability to generate longer, more narrative-driven content. The model accurately interprets the detailed instructions for camera movement, lighting, and color grading, resulting in a visually stunning and photorealistic scene. The subtle details, such as the glistening dew and hovering insects, demonstrate the model's advanced rendering capabilities.
Image-to-Video (I2V) Examples
Military Tactical Scene
Prompt: A modern soldier in full camouflage gear and helmet aims his rifle with precision while moving cautiously through a dense forest. Sunlight filters through the trees, creating shifting shadows on his uniform. His eyes focus intensely through the scope as he prepares to engage a target. Sound: faint rustling of leaves in the wind, footsteps crunching on dry branches, the metallic click of his rifle being adjusted, his steady breathing inside the helmet, and distant bursts of gunfire echoing through the forest.
This I2V example demonstrates Wan 2.5's ability to animate realistic military scenarios with exceptional attention to detail. The model successfully brings the static soldier image to life with natural movement, realistic equipment handling, and immersive environmental audio. The synchronized sound design creates a compelling tactical atmosphere that enhances the visual narrative.
Futuristic Android Interface
Prompt: A sleek female android with glowing blue eyes and silver armor stands in a futuristic laboratory. Suddenly, glowing holographic menus and data screens materialize in front of her, floating in the air. She raises her hand and interacts with them, her fingers moving quickly as she swipes through data and taps glowing symbols. Neon blue light reflects on her metallic body as the holograms shift and expand around her. Sound: soft electronic beeps and chimes with each touch, the faint hum of holographic projections, mechanical servo movements as she gestures, and her calm synthetic voice saying, "Accessing mainframe… data transfer in progress."
This example showcases Wan 2.5's capability to animate complex sci-fi scenarios with interactive elements. The model successfully generates holographic interfaces that respond to the character's movements, while maintaining consistent lighting and reflections on the metallic surfaces. The synchronized dialogue and sound effects create a convincing futuristic interaction.
Post-Apocalyptic Urban Scene
Prompt: In a post-apocalyptic abandoned city street, with broken windows, rusted cars, and overgrown weeds, a motorcycle speeds across the scene from left to right. The rider passes quickly, leaving behind the echo of the engine as dust and small debris scatter in its wake. The camera stays fixed on the ruined street as the motorcycle zooms by, adding life to the desolate environment. Sound: loud motorcycle engine revving, tires screeching lightly against cracked asphalt, the rumble echoing between empty buildings, and the faint rattle of loose metal as the bike speeds past.
This I2V example demonstrates the model's ability to add dynamic action to static environmental scenes. The motorcycle movement creates a compelling narrative moment while the detailed sound design enhances the post-apocalyptic atmosphere. The model successfully maintains the desolate mood while introducing kinetic energy through the passing vehicle.
Martial Arts Training Scene
Prompt: A fierce martial artist woman with long dark hair in a ponytail, wearing a white gi with golden dragon embroidery, standing inside a traditional Japanese dojo at sunset. She clenches her fists with focus, her stance shifting into a combat-ready pose. The camera slowly circles around her from waist-up to full body, capturing her determined expression. Dust particles float in the warm light beams coming from the windows.
This example highlights Wan 2.5's proficiency in animating character-focused scenes with cultural authenticity. The model successfully captures the martial arts movements and the serene yet focused atmosphere of the traditional dojo setting. The camera movement and lighting effects create a cinematic quality that enhances the character's presence and determination.
