Choose the Right Vidu API Workflow for Video Generation

Compare Vidu endpoints for reference guided video, start and end frame generation, and single image animation, including each model’s standard Atlas Cloud base price.

ModalityDescription
Vidu Reference-to-Video Q1 API (Reference to Video)Reference imagery guides the Q1 endpoint as it generates video output. Atlas Cloud lists a standard base price of $0.40, making this model suitable for reference guided concept clips and visual storytelling workflows.
Vidu Reference-to-Video 2.0 API (Reference to Video)For reference driven production with Vidu 2.0, supply reference imagery and receive generated video. Its standard base price is $0.20 on Atlas Cloud, which suits recurring character, product, and scene visualization tasks.
Vidu Start-End-to-Video 2.0 API (Start and End Frames to Video)Provide opening and closing frames, and this Vidu 2.0 endpoint generates the video between them. Atlas Cloud records a standard base price of $0.075, positioning it for planned transitions, visual reveals, and storyboard sequences.
Vidu Image-to-Video 2.0 API (Image to Video)A source image becomes generated video through the Vidu Image-to-Video 2.0 endpoint. With a standard Atlas Cloud base price of $0.075, it fits product image animation, social content, and still image motion workflows.

Inside the Vidu API: Consistency, Sound, and Cinematic Control

From four image reference consistency to native audio and sixteen second 1080p clips, the Vidu API on Atlas Cloud puts Shengshu's entire Q series behind one pay-as-you-go endpoint.

Subject Consistency with the Vidu API

The Vidu API accepts one to four reference images and holds characters, products, and scenes visually consistent across every frame. That reliability makes serialized storytelling and brand safe product videos practical at scale.

Start and End Frame Interpolation

Upload a start frame and an end frame, and the model builds the smooth transition between them on its own. Motion designers use this for morphs, reveals, and precisely timed scene changes.

Native Audio in a Single Pass

Why render silent clips and score them later? Every Q3 endpoint can generate synchronized sound effects and background music in the same pass, so dialogue scenes and ads arrive ready to publish.

Sixteen Seconds, Up to 1440p

If a scene needs room to breathe, run clips up to 16 seconds at 540p to 1080p, with super resolution upscaling to 1440p. Fewer stitched shots means smoother stories and lighter post production.

Tunable Motion and Style

A movement amplitude setting shifts output from subtle cinematic drift to large dramatic action, while text to video endpoints switch between general and anime styles. Directors get shot level control without rewriting prompts.

Vidu vs Other Models - One Prompt

The same prompt, generated by Vidu and other leading video models

Prompt

A lone stunt driver drifts a matte black muscle car through a neon-lit night market in the rain. Open on a low tracking shot skimming wet asphalt as the car slides around a corner, sparks flying off a guardrail. Whip pan to vendors yanking their stalls back, paper lanterns swinging wildly. Cut to a drone shot spiraling overhead as the car threads between two buses with inches to spare, then a hard cut inside the cockpit: hands snapping the wheel, eyes flicking to a mirror filled with flashing police lights. End on a slow-motion 180 degree spin into a steaming alley, engine roar and rain hiss filling the soundtrack. Photorealistic, cinematic lighting, 10 seconds, 16:9 aspect ratio.

Seedance 2.0

Vidu Q2 Pro

Prompt

Anime style: a young swordswoman faces a colossal storm dragon above a shattered floating shrine. Start with a fast dolly-in on her eyes as lightning splits the sky, then a whip pan following her sprint across a crumbling stone bridge, debris lifting around her feet. The camera orbits as she leaps, her blade igniting with blue flame, while the dragon's jaws crash down where she stood a frame earlier. Pull back to an epic wide shot as her strike cleaves a lightning bolt in half and the shockwave ripples through the clouds. Crisp 2D cel shading, dynamic speed lines, thunder and a swelling choir in the score. 8 seconds, 16:9 aspect ratio.

Vidu Reference Images Power Repeatable Visual Stories

Vidu uses reference images to anchor consistent characters, products, and visual worlds across episodic storytelling, branded campaigns, preproduction concepts, social series, and educational content through one pay-as-you-go API on Atlas Cloud.

Episodic Characters with Vidu

Reference images help Vidu preserve a character’s identity while prompts place that subject in new scenes and actions. Series creators can build episodic shorts, character campaigns, and connected story chapters with stronger visual continuity.

Product Stories from Shared References

Use product reference images to keep shapes, colors, and details present as the setting and camera direction change. Commerce teams can produce campaign concepts, catalog motion clips, and launch stories around the same item.

Reusable Brand Worlds

Logos, mascots, and signature environments can serve as references, guiding Vidu toward consistent brand elements across fresh scenes. Marketing studios gain reusable visual foundations for seasonal campaigns, localized variants, and multi-shot brand storytelling.

Preproduction Concept Testing

When a script needs visual proof, combine reference subjects and written direction to generate coherent concept clips before production. Directors can evaluate casting, blocking, scene continuity, and campaign ideas without committing to a shoot.

Recurring Social Personas with Vidu

Could one recognizable persona anchor a whole social series? Vidu uses reference images to maintain that subject across prompted situations, helping creator tools produce recurring hosts, virtual personalities, and serialized short-form content.

Vidu for Connected Learning Stories

Anchor educational narratives with reference images of artifacts, settings, or recurring guides, then prompt new actions while helping preserve their visual identity. Museums and learning teams can create explainers, cultural stories, and lesson sequences.

Vidu API FAQ for Consistent Video Generation

Vidu is a family of AI video generation models developed by ShengShu Technology in collaboration with Tsinghua University. It supports text to video, image to video, reference to video, and start and end frame workflows, including models designed to preserve subject identity across a clip.

Use reference images to place recognizable characters, products, objects, or environments into a generated video. This workflow is useful for recurring characters, branded product scenes, short narratives, advertisements, and other projects that need visual continuity.

Reference to video uses supplied images to guide subject identity without treating them strictly as the opening frame. Image to video animates a source image, while start and end frame generation creates the motion connecting two specified frames.

Create an Atlas Cloud API key and send a POST request to /api/v1/model/generateVideo with Bearer authentication. Include the selected model identifier and its required inputs, such as a prompt and reference images. The response provides an ID, status information, and output URLs when available.

Accepted reference formats include PNG, JPEG, JPG, and WebP, supplied through accessible URLs or valid Base64 data. Limits depend on the endpoint: Reference to Video 2.0 accepts one to three images, while Q3 Mix accepts one to four. Check the selected model schema before constructing the request.

For better consistency, use clear reference images and describe each subject, action, setting, and camera movement explicitly. Keep identities and clothing visually compatible across inputs, and avoid combining conflicting scene instructions in one prompt.

Atlas Cloud lists standard per generation prices of $0.40 for Reference to Video Q1, $0.20 for Reference to Video 2.0, and $0.075 for either Image to Video 2.0 or Start and End to Video 2.0. Other models have their own pay as you go rates, so review the selected endpoint before submitting a job.

Generation runs asynchronously, so retain the task ID returned after submission and monitor its status. Once processing succeeds, retrieve the generated video from the output URL in the result. Store completed media promptly if your application requires long term availability.

First verify the API key, model identifier, required parameters, image accessibility, file format, and endpoint specific limits. If identities drift, try clearer references with consistent lighting and fewer conflicting details, then simplify the prompt. Use the returned error information to diagnose rejected or failed requests.
