## Getting the best out of Kling 4.0 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.
