The camera rotates around the frozen figure as their clothing slowly melts into animated paint strokes
A woman warrior with her hammer walking with his glacier wolf.
The character in the image starts singing emotionally on a small spotlighted stage, camera slowly zooming in on her face
The image transitions into a cinematic tracking shot through a futuristic subway with the character looking around in awe
The person in the image begins to dissolve into liquid chrome, reflections warping around a moving camera
The character dissolves into flower petals that spiral upward into the sky, surreal and magical ambiance
The character in the image throws a punch in slow motion, sweat flying off in cinematic detail, gym lights glowing
The girl in the image begins to run joyfully across a blooming meadow, arms outstretched, birds flying in background
A slow motion shot of a woman walking through a street market at sunset, soft golden light reflecting off fresh produce and colorful textiles, vendors chatting and people smiling in the background. The camera gently tracks her from behind as her hair sways.

Example Prompts
- "The camera rotates around the frozen figure as their clothing slowly melts into animated paint strokes"
- "Flowers bloom and unfurl in timelapse, petals transforming into butterflies that flutter away"
- "Portrait dissolves into swirling particles that reform into an abstract geometric pattern"
- "Slow zoom out as the scene transforms from day to night, lights gradually illuminating"
- "Liquid metal flows across the surface, reflecting rainbow colors as it moves"
Pro Tips for Best Results
- V4.5 excels at transformation effects — describe morphing, melting, flowing, dissolving motions.
- Use artistic language: "paint strokes", "particles", "liquid", "flowing", "morphing".
- Combine camera motion with subject transformation for more dynamic results.
- Include environmental changes: lighting shifts, color transformations, atmospheric effects.
- Use negative prompts to avoid "static", "frozen", "still" if you want more motion.
- Start with 5-second videos to test complex transformations before generating longer versions.
Notes
- If using a URL for the image, ensure it is publicly accessible. A preview thumbnail confirms successful loading.
- Processing time varies based on resolution and duration.
- This model is optimized for artistic and dramatic motion — perfect for creative content.
- Best results come from images with interesting textures or subjects that lend themselves to transformation.

What is the Pixverse v4.5 I2v Fast API?
Pixverse v4.5 I2v Fast is a Pixverse model for video generation from images, exposed as a REST API on WaveSpeedAI. Pixverse V4.5 I2V Fast converts images or text into high-quality videos with multi-resolution, aspect-ratio and motion-mode control. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
How do I call the Pixverse v4.5 I2v Fast API?
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/pixverse/pixverse-pixverse-v4.5-i2v-fast.
How much does Pixverse v4.5 I2v Fast cost per run?
Pixverse v4.5 I2v Fast starts at $0.50 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
What inputs does Pixverse v4.5 I2v Fast accept?
Key inputs: `prompt`, `image`, `resolution`, `duration`, `seed`, `negative_prompt`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/pixverse/pixverse-pixverse-v4.5-i2v-fast.
How long does Pixverse v4.5 I2v Fast take to generate?
Average end-to-end generation time on WaveSpeedAI is around 56 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.
Can I use Pixverse v4.5 I2v Fast outputs commercially?
Commercial usage rights depend on the model's license, set by its provider (Pixverse). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
