- pixverse/c1-t2v: [Core Function] PixVerse c1 T2V generates a video purely from a text prompt, with no input image. [Strengths] Strong prompt adherence and smooth motion; optional audio. [Best For] Turning an idea or script into video, concept visualization, story beats, social clips from text. [Limitations] Do NOT use this when the user provides a starting image, two frames, or reference images; route to Image-to-Video, First-Last-Frame, or Reference-to-Video instead. c1 does not support multi-clip. [Routing] Use for text-only generation. The c1 variant takes the same inputs as v6 except it does not support multi-clip generation; choose c1-t2v when the user requests the c1 model and multi-clip is not needed.
- pixverse/c1-fl2v: [Core Function] PixVerse c1 first-last-frame generates a video that transitions from a start frame to an end frame, guided by a prompt. [Strengths] Controlled start/end composition with smooth interpolation. [Best For] Morphs, scene transitions, before/after motion. [Limitations] Do NOT use this if you only have a single image (use Image-to-Video) or lack an end frame; it requires exactly two images (a first and a last frame) and supports up to 1080p and a maximum of 15s. [Routing] Use when the user provides a start image AND an end image. For one image use Image-to-Video. The v6 and c1 first-last-frame variants accept identical parameters; choose the version the user requests.
- pixverse/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.
