FLUX 3 Audio and Dialogue
Name each layer separately: speech, voiceover, ambience, effects, music, or deliberate silence. One blurred description gives up control of all of them; every sound needs a physical source or narrative role.
Speech. Quote the exact line, name the visible speaker (or label the line
voiceover/narration so it is not searching for a mouth to belong to), and add
no on-screen text, no subtitles when text is unwanted:
textA weather presenter on camera in front of a stylized storm map, speaking directly to the lens: "Storm season is here, and this time, we're ready." Confident delivery, clean studio lighting. No on-screen text, no subtitles.
Voice anchors: age range, accent when relevant, register, energy, recording distance. Reusing the same direction preserves a kind of voice, not the same performer across generations.
Speakability. Write for the clip's real duration: short sentences, one thought per line, room before and after the payoff; spell unusual names phonetically; shorten the line before speeding the delivery. A line that cannot finish comfortably needs a shorter script or a longer clip.
Effects are causal, not a detached list:
textAs the cup hits the tile, it cracks with one sharp ceramic snap.
Mix. Say what leads and what stays under it. Keep background voices out when one line matters:
textHer line is foreground and fully intelligible. Café chatter and espresso hiss remain low and diffuse. A restrained piano pulse enters beneath the final words without masking them.
Silence and post. Set generate_audio: false for a deliberately silent source
clip. Reserve for deterministic post: final loudness, EQ, ducking, and fades;
guaranteed wording or speaker identity; frame-accurate sync; subtitles and captions;
continuity across separately generated clips.
When a take misses, change one dimension at a time: speaker ownership, line length, delivery anchors, competing layers, action-to-effect causality, or generation versus post.
