Tutorial: Split Screen AI in After Effects

Split Screen AI in AEJuice Pack Manager builds a split screen composition from your video and a background gameplay clip, with captions generated for you.

1. Set the caption options

Open the dialog and set what the captions should look like:

  • Language: Auto
  • Grouping: Word by word
  • Capitalization: ALL CAPS

Brand, Output and Advanced hold the rest of the settings.

2. Pick a gameplay category and import

Choose a background category from the list — Minecraft, Subway, Trackmania, Slime, Soap, Circle Video — then hit Import. A “Processing, it can take a few minutes” notice appears while it works.

3. The composition is built

Your video and the gameplay clip end up in one finished Split Screen composition, ready to preview on the timeline.
