Getting the best out of FLUX 3 Edit

  • Describe one continuous camera move and where it ends. The model renders motion, not a shot list.
  • Attach the real product photo as a reference and ask for it matched exactly. Never describe a lookalike.
  • Name colours in words. A hex code turns into text on screen.
  • Keep spoken lines short. Roughly two words per second is what a clip can carry cleanly.
  • Ask for the placement's ratio up front (9:16 for Reels and TikTok) instead of cropping afterwards.

Frequently asked questions

What does FLUX 3 Edit do?

FLUX 3 Edit changes a video you already have from one instruction: a new look, setting, season or colour, while the shots, motion and timing stay. It does not make a video from scratch.

How long a clip can FLUX 3 Edit edit?

Clips up to 15 seconds. The result keeps the source clip's length and framing.
