Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response

API README

Vidu Q2 Image to Video Pro

Teams can place this named operation inside review, asset preparation, and publishing pipelines while keeping the original request attached to every result. Vidu Q2 Pro by Shengshu - animate still images into dynamic videos with AI. Transform photos into cinematic clips with natural motion, camera movement, and optional audio generation. Vidu Q2 Image to Video Pro is designed around the vidu/q2/image-to-video/pro workflow for pro work in video production. Because vidu/q2/image-to-video/pro is a separate catalog entry, evaluations should use this route’s own inputs, output expectations, and billing behavior. The endpoint is especially useful when a project has a defined transformation goal and needs a repeatable request contract instead of an ad-hoc desktop step. This capability boundary is specific to the endpoint named above.

bgm controls whether to add background music to the video (only for 4-second videos); seed controls random seed for reproducibility. If None, a random seed is chosen; image controls uRL of the image to use as the starting frame; prompt controls text prompt for video generation, max 3000 characters; duration controls duration of the video in seconds; duration accepts 2, 3, 4, 5, 6, 7, 8; end image controls uRL of the image to use as the ending frame. When provided, generates a transition video between start and end frames; resolution controls output video resolution. The mandatory portion is image, prompt. Vidu Q2 Image to Video Pro exposes bgm, seed, image, prompt, duration, end_image, resolution as its documented request surface. For example, the route documentation includes “https://static.sandbase.ai/examples/shengshu/vidu/q2/image-to-video/pro/input_image_0.webp”. Applications can submit that exact shape asynchronously, retain the chosen arguments in job metadata, and collect the resulting media URL for review or publishing.

Highlights

Coherent motion. Vidu Q2 Image to Video Pro is built to turn the route’s text or reference media into a temporally connected sequence rather than unrelated frames.
Shot direction. Prompts can describe subject action, camera movement, pacing, and atmosphere so Vidu Q2 Image to Video Pro has a concrete motion plan.
Reference-aware generation. When this route accepts source media, Vidu Q2 Image to Video Pro uses it to anchor identity, composition, or the clip boundary throughout generation.
Production variants. Declared duration, resolution, framing, or inference controls support repeatable video options for review and selection.

When to Use

Scenario	Why it fits
Choose Vidu Q2 Image to Video Pro	Use it when the job specifically calls for pro and the route’s documented input contract matches assets already available in your workflow.
Keep the request reproducible	Use the required `image`, `prompt` explicitly, then record optional choices alongside the prompt for repeatable reruns.
Build controlled creative variations	Change one declared control at a time when comparing framing, format, duration, resolution, style, or other route-supported output decisions.
Integrate asynchronous delivery	Use this endpoint when an application can submit work, track completion, and collect the returned media URL instead of requiring an immediate inline artifact.
Validate before a large batch	Run representative prompts and source assets first, confirm the visual or audio behavior, then lock the successful request shape for scaled production.

Prompt Guide

Lead with the subject or transformation, then add the composition, environment, style, lighting, motion, voice, or fidelity details relevant to this route. Keep every parameter inside the documented schema; the example below uses only fields declared for vidu/q2/image-to-video/pro.
