# FLUX.3 Extend

> Video AI Model by Black Forest Labs — available on Layer

Extend an existing video clip with FLUX.3, continuing motion and native audio from the source ending.

FLUX.3 Extend continues an existing clip using Black Forest Labs FLUX.3, generating new frames from the source video's ending with optional text direction. It produces 720p or 1080p output with native synchronized audio, making it ideal for lengthening takes, building multi-beat sequences, and iterating on cinematic game trailers without restarting from scratch.
