# PixverseV6FirstLastFrameNode - ComfyUI Built-in Node Documentation

> PixVerse V6 First-Last-Frame to Video generates a video that transitions from a first frame to a last frame using PixVerse, optionally with native audio.

PixVerse V6 First-Last-Frame to Video generates a video that transitions from a first frame to a last frame using PixVerse, optionally with native audio. The two provided images are sent to the PixVerse API, which produces the transition video and returns it as a video file. The output keeps the aspect ratio of the first frame.
