Preparing Your Script for AI Video Creation and Script to Storyboard AI

A good script is key for AI video production. Knowing how to turn a script into visuals helps.

Understand Script Formats

When prepping your script for AI:

  • Break it into scenes so AI matches the video flow.
  • Add notes on visuals to guide the AI.
  • Mark different speakers for correct voices.
  • Keep scripts under about 1,500 characters for best results.

Adjust Scripts for AI Tools

Make scripts clear and simple. Keep sentences short to help AI process them better. Specify your preferences like language and voice style.

Write Effective Scripts

Great scripts tell stories well:

  • Use about 150 words per minute of video.
  • Write like you talk for a natural feel.
  • Say your main points clearly.
  • Tell a story to keep viewers interested.
  • Use descriptive words to help AI pick fitting visuals.
