Vidu 2 Reference

Zhipu AI Vidu 2 Reference β€” 4s 1280Γ—720 video conditioned on 1+ reference images. Pricing/reference-count details pending ops re-verification against docs.bigmodel.cn.

Vidu 2 Reference is Zhipu AI's reference-image video generation mode in the Vidu 2 family. It accepts one or more reference images plus a text prompt, then creates a short video that preserves subject identity and visual style across the generated motion. The official guide positions Vidu 2 as the speed-and-cost balanced generation, with 4-second 720p output and stronger consistency for multi-reference inputs.

Use the TheRouter model id zhipu/vidu2-reference when you need a lower-cost 720p reference-video route rather than Vidu Q1's higher-resolution generation. The upstream Zhipu API names the model vidu2-reference; TheRouter exposes the same reference-video capability through its routed video-generation surface, with auth, pricing, and supported parameters taken from the live model catalog.

Best for
  • β€’ Character, object, or product clips where reference images must anchor the generated subject identity
  • β€’ High-volume advertising and e-commerce variants that need 4-second 720p video at lower cost than the Q1 generation
  • β€’ Anime shorts, IP spin-offs, and UGC effects where several static assets should share one visual style
  • β€’ Rapid concept tests before spending on higher-resolution or longer video models
Reach for something else if
  • β€’ Pure text-to-video prompts with no reference assets β€” route to a text-to-video model such as zhipu/viduq1-text
  • β€’ First-to-last-frame interpolation where both endpoints are fixed β€” route to zhipu/vidu2-start-end or zhipu/viduq1-start-end
  • β€’ Deliverables that require 1080p output β€” Vidu 2 is documented for 720p; choose a Q1 route instead
  • β€’ Tasks requiring verified snippets today β€” examples stay unproven until a human approves a funded verification run

How TheRouter serves this differently from the vendor

As the vendor operates it

Zhipu's native MaaS API exposes Vidu 2 Reference at /api/paas/v4/videos/generations using upstream model name vidu2-reference and accepts image_url as an array of reference images.

On TheRouter

TheRouter serves the same reference-video capability under public id zhipu/vidu2-reference through its routed video-generation surface with unified TheRouter auth, model catalog pricing, and supported-parameter metadata.

Zhipu documents Vidu 2 Reference for 4-second 720p reference-video generation

The Vidu 2 guide describes image-to-video, start-end-frame, and reference-video modes. Reference mode accepts multiple images plus a prompt, with Vidu 2 positioned as a faster, lower-cost 720p generation tier for entertainment, e-commerce, anime shorts, and advertising production.

Frequently asked

How is Vidu 2 Reference different from Vidu 2 Start-End?

Reference mode uses one or more images as identity or style references while generating a new short video. Start-End uses exactly two endpoint frames, where the first image is the opening frame and the second image is the final frame.

re-authored by TheRouterdocs.bigmodel.cn β†—
How long and what resolution are Vidu 2 Reference outputs?

The official Vidu 2 guide lists Reference output as 4 seconds at 720p. The TheRouter catalog default for this route is 1280Γ—720, with duration fixed at 4 seconds.

Are the snippets on this page verified against the live API?

No. This scheduled curation loop has no paid API budget, and snippet verification requires an operator-set approval flag. Treat the snippets as integration-shaped examples until a human funds and approves verification.
