SetFootageFPS

Quick After Effects script to change the frame rate of selected footage items or layers.

What it does

SetFootageFPS lets you instantly change the conform frame rate of footage without diving into interpret footage dialogs:

1. Prompts for new FPS (defaults to 23.976)
2. Applies to selected items - works on both footage in Project panel and layers in Timeline
3. Batch processing - handles multiple selections at once
4. Smart detection - automatically finds the source footage for timeline layers

Perfect for quickly conforming footage to match project settings or fixing frame rate issues.

Installation

1. Copy SetFootageFPS.jsx to your After Effects Scripts folder:

   Windows: C:\Program Files\Adobe\Adobe After Effects [version]\Support Files\Scripts\
   macOS: /Applications/Adobe After Effects [version]/Scripts/
   

2. Restart After Effects

• Common mistake: Remember this changes interpret settings, not composition frame rate
• Decimal precision: Use 23.976, 29.97, 59.94 for broadcast standards
• Multiple selection: Select all footage first, then run once
• Layer workflow: You can select timeline layers instead of hunting for footage in project
