Vidu Start End to Video Q2 Turbo | Fast Image-to-Video API

Vidu Q2 Start-End to Video Turbo

Vidu Q2 Start-End to Video Turbo creates a coherent video from just two images: a start frame and an end frame. Turbo accelerates bi-frame interpolation with optimized inference for faster turnaround and smoother motion — ideal for scene transitions, bridging shots, and rapid storytelling.

Why Choose This?

Bi-frame guidance Anchors identity, layout, and lighting from both start and end frames.
Turbo temporal smoothing Reduces flicker and popping while preserving subject integrity at higher throughput.
Object and human-aware motion Protects faces, hands, hair, and thin structures while animating garments and props.
Layout-smart interpolation Respects depth, occlusion, and parallax for clean foreground/background motion.
Adaptive camera pathing Natural pans, push-ins, and dolly moves without warping.
Speed-optimized pipeline Faster than Pro at the same settings, perfect for rapid iteration.

Best Use Cases

Storyboarding and Concept Animation — Animate between keyframes to preview beats in seconds.
Scene Interpolation — Seamless bridges between shots with consistent style.
Before/After Visualization — Visualize transformations with smooth, controlled motion.
Film Pre-visualization — Explore blocking and camera moves early and often.
Transitions — Create smooth video transitions between key moments.

Pro Tips

For large pose or layout jumps, try shorter durations or insert intermediate keyframes.
Use consistent lighting and style between start and end frames for smoother interpolation.
Turbo generally returns faster than Pro at the same settings.
Add a prompt to guide the motion style and camera movement between frames.

Notes

Maximum duration is 10 seconds per generation.
Actual processing time depends on resolution, duration, and current queue load.
Ensure you have rights to all uploaded images.
For complex transformations, consider using intermediate keyframes.

Start End To Video Q2 Turbo API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/vidu/start-end-to-video-q2-turbo 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 Start End To Video Q2 Turbo below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/vidu/start-end-to-video-q2-turbo" \
  -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",
    "duration": 5,
    "resolution": "720p",

Start End To Video Q2 Turbo API — Frequently asked questions

What is the Start End To Video Q2 Turbo API?

Start End To Video Q2 Turbo is a Vidu model for video generation from images, exposed as a REST API on WaveSpeedAI. Vidu Q2 Turbo Start-End to Video creates smooth Image-to-Video transitions between start and end images with fast high-quality results. 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 Start End To Video Q2 Turbo 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/vidu/vidu-start-end-to-video-q2-turbo.

How much does Start End To Video Q2 Turbo cost per run?

Start End To Video Q2 Turbo 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 Start End To Video Q2 Turbo accept?

Key inputs: `prompt`, `image`, `resolution`, `duration`, `seed`, `bgm`. 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/vidu/vidu-start-end-to-video-q2-turbo.

How long does Start End To Video Q2 Turbo take to generate?

Average end-to-end generation time on WaveSpeedAI is around 184 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Start End To Video Q2 Turbo outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (Vidu). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
