Missing B-roll kills pacing. Here is how to generate short AI cutaways inside After Effects (and Premiere) so you are not hunting stock at midnight.

Why generate AI B-roll inside After Effects?

External AI video sites add friction: export prompt → wait → download → import → colour match. An AI B-roll plugin for After Effects keeps aspect ratio, credits, and import in one place. Superconductor does that for AE and Premiere Pro.

Step-by-step: AI B-roll with Superconductor

  1. Install Superconductor from Keyweaver Manager (After Effects tab).
  2. Open your edit comp and launch Window → Extensions → Keyweaver - Superconductor.
  3. Write a prompt, pick aspect (active comp, 16:9, 9:16, 1:1), length, and quality.
  4. Confirm credit cost → generate → import from the library onto the timeline.

Prompt tips that look like real editorial plates

  • Describe camera move (slow dolly, gentle orbit, static with light shift).
  • Specify lighting (softbox, neon night, morning window).
  • Say no text, no logos when you need clean compositing space.
  • Match the grade: "charcoal studio", "warm lifestyle", "cool cyber night".
