Run Wan 2.5 on Pollo API
Wan 2.5 can generate video with matching audio or use uploaded audio as guidance. This makes it useful for clips where sound, motion, and timing need to work together.
With Wan 2.5 on Pollo API, developers add text-to-video and image-to-video generation to their apps, with native audio, negative prompts, and every aspect ratio available at 480P, 720P, or 1080P.
Key Features of Wan 2.5 API
Native Audio Generation
Wan 2.5 produces synchronized sound with the video by default, so ambient noise, effects, and scene audio arrive together instead of needing a separate scoring pass.
Audio-Driven Video
Feed an audio track and Wan 2.5 shapes motion and timing to it, aligning a character's movement or a scene's rhythm to the sound you supply.
Improved Motion Physics
Movement follows more believable physics, so limbs, cloth, and moving objects travel with weight and continuity rather than sliding or jittering between frames.
Sharper Prompt Awareness
The model reads described subjects, actions, and staging more closely, so what you write lands in the shot and reduces the number of rerolls per idea.
Flexible Framing
All aspect ratios work across every resolution, so square, portrait, and widescreen outputs come from one model without cropping or reframing later.
Negative Prompt Control
State what to leave out, and Wan 2.5 steers away from it, giving cleaner results when a scene keeps pulling in unwanted objects, colors, or artifacts.
Use Cases of Wan 2.5 API
- Sound-Synced Explainers: Generate short how-to clips where narration or effects match on-screen action, letting product tools ship video with audio in one call.
- Audio-Led Character Clips: Upload a voice or music track and let Wan 2.5 drive a character's movement and pacing to it for talking or performing shots.
- Ambient Scene Loops: Produce nature or environment clips where generated sound, like rushing water or crackling fire, completes the atmosphere without extra editing.
- Image-to-Motion: Feed a still image and animate it into a short moving shot that keeps the original composition while adding motion and sound.
- Vertical Social Content: Build 9:16 clips at full resolution for short-form feeds, using native audio to skip a manual sound step in the pipeline.
- Multi-Ratio Ad Variants: Generate the same concept in square, portrait, and widescreen from one model to cover different placements at once.
- Rhythm-Matched Montages: Supply a beat or music bed and let the model time cuts and motion to it for music-reactive creator tools.
- Prompt-Faithful Prototyping: Preview a described scene quickly, trusting tighter prompt adherence to reflect the brief before committing to a longer production.
How to Use Wan 2.5 API
- Get an API Key: Create a Pollo API account and generate your API key from the developer dashboard.
- Choose the Model: Send your request to the Wan 2.5 endpoint at
/generation/wanx/wan-v2-5-preview. - Add Your Inputs: Provide a
promptfor text-to-video or animageURL for image-to-video, then setresolution(480P, 720P, 1080P) andlength(5 or 10). PassaudioUrlfor audio-driven generation or keepwanAudioon for generated sound. - Generate and Retrieve: Submit the task, poll the returned task status, and download the finished video once processing succeeds.
Prompting Best Practices for Wan 2.5 API
Write for both picture and sound. Name the subject and action, then describe the audio you expect, the framing, and the mood, so the model can align motion with the track.
A Simple Prompt Formula
Subject + specific action + audio or sound cue + camera and framing + setting and mood
What You Should Notice
- Describe The Sound: Name the audio you want, such as footsteps, waves, or a spoken line, so native audio has a clear target.
- Match Motion To Audio: When supplying a track, describe how movement should follow it, like steps landing on the beat.
- Pick The Ratio Early: Choose square, portrait, or widescreen up front so composition is framed for its final placement.
- Use Negative Prompts: List what to exclude when a scene keeps adding clutter, harsh light, or unwanted elements.
- Keep One Clear Action: Focus each 5 or 10 second clip on a single motion so picture and sound stay coherent.
- Set A Seed To Repeat: Reuse a seed when you want to iterate on a result without losing the framing you liked.
Example Prompts
Ambient Sound Scene
"A cast-iron pan sizzles as sliced onions hit hot oil, steam rising, a wooden spoon stirring slowly. Generate matching sizzle and stir sounds. Overhead close-up, warm kitchen light, realistic style, unhurried motion."
Audio-Driven Performance
"A street accordion player sways and pumps the bellows in time with the supplied music track, foot tapping the pavement. Medium shot at dusk, soft streetlamp glow, movement synced closely to the audio rhythm."
Nature Atmosphere
"A narrow forest waterfall drops into a clear pool, mist drifting, ferns trembling from the spray. Generate flowing water and birdsong. Slow push-in, dappled morning light, portrait 9:16 framing, calm realistic tone."
Image-Led Animation
"Animate the provided photo of a lantern-lit night market: steam curling from food stalls, string lights swaying, a vendor waving. Add gentle crowd murmur and ambient audio. Keep the original composition, slow lateral camera drift."

Wan 2.5 API FAQs
What is Wan 2.5?
Wan 2.5 is a video generation model from wanx that supports text-to-video and image-to-video with native audio, audio-driven motion, improved physics, and sharper prompt awareness.
Does Wan 2.5 API generate audio?
Yes. It produces synchronized sound with the video by default, and you can also upload an audio track to drive the motion and timing of the clip.
What inputs does Wan 2.5 support?
You can generate from a text prompt, animate an image URL, and optionally supply an audio file, making it flexible for idea-first, asset-first, and sound-first workflows.
What resolutions and lengths are available?
Wan 2.5 outputs 480P, 720P, and 1080P at any aspect ratio, with clip lengths of 5 or 10 seconds selected per request.
How does audio-driven generation work?
Provide an audio URL and Wan 2.5 builds the video's motion and pacing around that track, aligning movement to the sound instead of generating its own audio.
Why run Wan 2.5 through Pollo API?
Pollo API gives one integration for Wan 2.5 and 300+ other models, with documentation, task tracking, webhooks.
