DescriptTry it →Watch full video →Danie JayDanie Jay·

Demo summary

The creator demonstrates prompting the Underlord AI assistant to make a video more engaging, which automatically adds B-roll and text overlays.

Step-by-step

  1. Open the Underlord section in Descript
  2. Enter a prompt asking for creative suggestions to make the video more engaging
  3. Provide context including the video topic, target audience, platform, and goal
  4. Review the list of recommendations generated by the AI
  5. Select specific recommendations or choose 'Implement them all'
  6. Wait for Underlord to automatically add B-roll, import video, and create text overlays

Options

  • Ask for five 30-second clips from the most engaging moments
  • Request specific additions like captions and music
  • Go back and forth with the AI to refine ideas before implementing

Watch out for

  • Underlord works best when treated as a creative partner rather than just a command tool

Tips

  • Tell the AI what to do rather than what not to do (e.g., use 'make this more conversational' instead of 'make this less robotic')
  • Get specific with your prompts to improve energy, pacing, or visual appeal
  • Provide the AI with the specific platform and audience context for better results

Highlights

“Descript is a powerhouse now... How wild is this?”
