Veo 2 I2V

[Core Function] Veo 2 I2V is an older generation image-to-video model. [Strengths] Known for its distinctive cinematic style and fluid motion priors from the Veo 2 era. Maintained for backward compatibility. [Best For] Existing legacy integrations and workflows that strictly depend on this specific model version’s quirks. [Limitations] Do NOT use this for new creations. It is a legacy model maintained for backward compatibility. [Routing] Only use if explicitly requested; otherwise use Veo 3.1 I2V.
