Pixverse V4.5 T2V | Powerful Text-to-Video API

PixVerse V4.5 — Text-to-Video

PixVerse V4.5 Text-to-Video is a high-quality text-to-video generation model with support for resolutions up to Full HD 1080p. Generate detailed, cinematic videos from text descriptions with flexible aspect ratios and multiple resolution options.

Why It Stands Out

Up to 1080p Full HD: Generate crisp, high-resolution videos for professional use.
Multiple resolutions: Choose from 360p, 540p, 720p, or 1080p based on your needs.
Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
Flexible aspect ratios: Wide range from 16:9 widescreen to 9:16 vertical.
Negative prompt support: Exclude unwanted elements for cleaner outputs.
Reproducibility: Use the seed parameter to recreate exact results.

Set duration — choose 5 or 8 seconds.
Add a negative prompt (optional) — specify elements to exclude.
Click Run and wait for your video to generate.
Preview and download the result.

Best Use Cases

Cinematic Content — Generate 4K-style cinematic shots and scenes.
Social Media Content — Create platform-optimized videos for any channel.
Marketing & Advertising — Produce high-quality promotional videos.
Sci-Fi & Fantasy — Generate detailed, imaginative scenes.
Rapid Prototyping — Use lower resolutions for quick concept testing.

Pricing

Resolution	5 seconds	8 seconds
360p	$0.25	$0.50
540p	$0.25	$0.50
720p	$0.35	$0.70
1080p	$0.70	$1.40

Pro Tips for Best Quality

Be detailed in your prompt — describe subject, action, environment, lighting, and style.
Include quality keywords like "4K," "cinematic shot," or specific visual descriptions.
Use 360p or 540p for quick iterations, then generate final version at 1080p.
Use negative prompts to reduce artifacts like blur or distortion.
Match aspect ratio to your target platform before generating.

Notes

Processing time varies based on resolution, duration, and current queue load.

Pixverse v4.5 T2v API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/pixverse/pixverse-v4.5-t2v with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Pixverse v4.5 T2v below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/pixverse/pixverse-v4.5-t2v" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "aspect_ratio": "16:9",
    "resolution": "540p",
    "duration": 5,
    "negative_prompt": "blurry, low quality, distorted",
    "seed": 0
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].

Node.js example

// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("pixverse/pixverse-v4.5-t2v", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "aspect_ratio": "16:9",
        "resolution": "540p",
        "duration": 5,
        "negative_prompt": "blurry, low quality, distorted",
        "seed": 0
});

console.log(result.outputs[0]); // → URL of the generated output

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "pixverse/pixverse-v4.5-t2v",
    {
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "aspect_ratio": "16:9",
    "resolution": "540p",
    "duration": 5,
    "negative_prompt": "blurry, low quality, distorted",
    "seed": 0
}
)

print(output["outputs"][0])  # → URL of the generated output

Pixverse v4.5 T2v API — Frequently asked questions

What is the Pixverse v4.5 T2v API?

Pixverse v4.5 T2v is a Pixverse model for video generation, exposed as a REST API on WaveSpeedAI. Pixverse v4.5 turns text prompts into high-quality videos with multiple resolutions, aspect ratios, and motion modes. 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 T2v 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-t2v.

How much does Pixverse v4.5 T2v cost per run?

Pixverse v4.5 T2v 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 T2v accept?

Key inputs: `prompt`, `aspect_ratio`, `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-t2v.

How long does Pixverse v4.5 T2v take to generate?

Average end-to-end generation time on WaveSpeedAI is around 65 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 T2v 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.
