Why Choose This?

Start-to-end frame transitions Generates a coherent video that naturally bridges two distinct images with smooth, believable motion.
Prompt-guided transformation Describe how the transition should unfold — scene changes, camera movements, environmental shifts, and more.
Eight aspect ratio options Supports 16:9, 9:16, 1:1, 4:3, 3:4, 3:2, 2:3, and 21:9 for any platform or format.
Four resolution tiers Generate from 360p up to 1080p to match your quality and delivery requirements.

Best Use Cases

Scene transitions — Bridge two distinct environments or visual states with a natural cinematic transition.
Before & after content — Create compelling before-and-after reveal clips for social media.
Seasonal & atmospheric changes — Shift between seasons, times of day, or weather conditions from the same scene.
Marketing & advertising — Transition between product states or campaign visuals for polished ad content.
Creative storytelling — Connect two visual moments with a smooth, motioned narrative bridge.

Pro Tips

Use images of the same scene or subject from different states for the most natural transition results.
Be specific in your prompt about what changes between the two frames — lighting, season, atmosphere, or subject state.
Use 360p to test your transition concept before committing to a 1080p final render.
Enable audio for transitions with strong environmental context like nature scenes, city environments, or action sequences.

Pixverse C1 Transition API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/pixverse/pixverse-c1/transition 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 C1 Transition below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/pixverse/pixverse-c1/transition" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "aspect_ratio": "16:9",
    "resolution": "720p",
    "duration": 5,
    "generate_audio_switch": false
}'

# 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-c1/transition", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "image": "https://example.com/your-input.jpg",
        "aspect_ratio": "16:9",
        "resolution": "720p",
        "duration": 5,
        "generate_audio_switch": false
});

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

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "pixverse/pixverse-c1/transition",
    {
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "aspect_ratio": "16:9",
    "resolution": "720p",
    "duration": 5,
    "generate_audio_switch": false
}
)

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

Pixverse C1 Transition API — Frequently asked questions

What is the Pixverse C1 Transition API?

Pixverse C1 Transition is a Pixverse model for video generation from images, exposed as a REST API on WaveSpeedAI. PixVerse C1 generates smooth transition videos between two images with flexible duration (1-15s), multiple resolutions up to 1080p, and optional native audio generation. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Pixverse C1 Transition 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-c1-transition.

How much does Pixverse C1 Transition cost per run?

Pixverse C1 Transition starts at $0.10 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 C1 Transition accept?

Key inputs: `prompt`, `image`, `aspect_ratio`, `resolution`, `duration`, `end_image`. 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-c1-transition.

How do I get started with the Pixverse C1 Transition API?

Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.

Can I use Pixverse C1 Transition 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.
