FLUX 3 Video
FLUX 3 Video is Black Forest Labs' multimodal foundation model for video generation with synchronized audio. It generates clips from 5 to 20 seconds across text-to-video, image-to-video, and video-to-video modes on one architecture, with keyframe control to pin an opening image or interpolate motion across pinned frames, chained continuations for arcs beyond 20 seconds, multi-shot sequences with hard cuts inside one generation, and native multilingual dialogue. A draft mode returns a fast low-resolution preview and a cache that a follow-up call enhances at full quality, tightening iteration loops. Style range spans candid camcorder footage, animation, motion design, and cinematic photoreal, character consistency holds across scenes within one generation, and in-video typography renders cleanly for titles and animated designs.
Audio and speech with FLUX 3 How to compose FLUX 3's synchronized audio: layering ambient and effects, directing music by instrumentation and tempo, directing speech delivery, and rendering multilingual dialogue with clean lip-sync.
Keyframes with FLUX 3 How to pin images to specific frame positions in FLUX 3 videos: opening on a source image, storyboarding across positions, ending on a packshot, morphing between two states, and using timestamps for beat-precise timing.
Multi-shot sequences with FLUX 3 How to build multi-shot video sequences inside one FLUX 3 generation: HARD CUT syntax, shot contrast, time compression, threading an audio bed across the cuts, and pacing shot rhythm.
Prompting FLUX 3 How to prompt FLUX 3 for text-to-video with synchronized audio: request shape, prompt rewriting, camera language, dimensions, style diversity, and the draft-mode iteration workflow.
Video continuation with FLUX 3 How to continue a source clip from its final frames with FLUX 3's video input: single-clip continuation, chaining across multiple generations, deliberate source design, and recovering shots that didn't land.
