FLUX 3 Text
FLUX 3 is Black Forest Labs’ video model on TheFluxTrain. Prompt for motion, pick 720p or 1080p, and generate with synchronized audio in one pass.
Quick answer: FLUX 3 generates up to 20 seconds of video with native audio from text, a still, start/end frames, or an existing clip on TheFluxTrain.
