C1 First-Last-Frame to Video
[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.
