[Strengths] It excels at quickly animating a static portrait image into a speaking or moving digital human, syncing lip movements to provided audio with low latency. [Best For] Highly recommended for: rapid generation of talking head videos, quick virtual presenters, and responsive interactive avatars. [Limitations] Do NOT use this model for complex full-body motion, multi-character interactions, or videos longer than 10 seconds. [Routing] Use this model when the user wants to make a portrait 'talk' quickly. For higher realism and better quality, route to Q2 Pro Digital Human. ## OpenAPI ````yaml /model-api/vidu/vidu-i2v.json post /vidu/viduq2-turbo-digital-human openapi: 3.1.0 info: description: >- The image-to-video models API from Vidu.
