The Speed & Timing Prompt

Control the timing of this shot.

Shot: [DESCRIBE]
Duration: [SECONDS]
Pace wanted: [DESCRIBE]
Where the emphasis falls: [DESCRIBE]

Produce:
1. How to specify speed in prompt terms
2. Whether to generate at normal speed and retime in post, or
   specify the speed at generation
3. What slow motion does and does not do in generated video
4. How to phrase acceleration or deceleration
5. Where the shot's beat should land within its duration
6. The prompt text

Then:
7. Whether this timing is better achieved in the edit than in the
   generation — often it is
8. What to generate so the edit has room to work: extra duration,
   clean starts and ends, no motion at the cut points

A practical note worth including: generating at normal speed and
retiming in post gives you far more control than asking for slow
motion, and it costs nothing extra.
