Fix a failed take / FLUX / prompt ignored

FLUX 3 video drops details or loses coherence: how to fix it

Later details in the prompt never show up, or the motion gets muddled.

Why it happens

• An over-stuffed prompt where later clauses compete with earlier ones.
• Several events in one shot.

Fixes, in order

1. Keep the brief short (one to three sentences) and build each shot around one clear event; lengthen only to lock the details that matter.

   “A shot brief is five slots in one to three sentences: subject, motion, setting and light, camera, audio cue.”— Morphed, 2026-08-07

   “Shots built around one clear event are the most reliable”— fal, 2026-10-12
