C1 Text-to-Video
[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.
