C1 I2V

[Core Function] PixVerse c1 I2V animates a single starting image into a video guided by a text prompt. [Strengths] Smooth, prompt-guided motion from one frame; optional audio. [Best For] Bringing a photo/illustration to life, product showcases, quick cinematic motion from a still. [Limitations] Do NOT use this for two-frame transitions (use First-Last-Frame), multi-subject fusion (use Reference-to-Video), or text-only generation (use Text-to-Video). It requires exactly one starting image, does not support multi-clip, and supports up to 1080p and a maximum of 15s. [Routing] Use when the user provides one starting image. The c1 variant matches v6 inputs but does not support multi-clip generation; choose c1-i2v when the user requests the c1 model and multi-clip is not needed.
