- Start with 540p to test concepts — it offers great quality at the base price.
- Describe the emotional tone: "confident", "playful", "elegant", "dramatic".
- Keep the same seed when upgrading resolution to maintain consistency.
Notes

What is the Pixverse v4.5 I2v API?
Pixverse v4.5 I2v is a Pixverse model for video generation from images, exposed as a REST API on WaveSpeedAI. PixVerse V4.5 I2V creates high-quality videos from text or image prompts, offering multiple resolutions, aspect ratios, and motion modes for versatile cinematic output. 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 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.
How much does Pixverse v4.5 I2v cost per run?
Pixverse v4.5 I2v starts at $0.25 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 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.
How long does Pixverse v4.5 I2v take to generate?
Average end-to-end generation time on WaveSpeedAI is around 22 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 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.
