The Problem
Your project file is out of control.
Over time, AE projects accumulate junk. Reducer cleans the mess safely.
💾
Bloated File Sizes
Projects balloon to hundreds of megabytes with unused footage, abandoned comps, and orphaned solids. Saving takes forever, sharing is impossible.
✓ Reducer: Shrink project size by up to 70%
🔎
Finding Unused Assets
After Effects gives you no easy way to see what's actually in use. You're left digging through the Project panel, guessing which files are safe to remove.
✓ Reducer: One-click scan finds everything unused
😱
Fear of Breaking Things
You want to clean up, but what if you delete something a precomp depends on? What if a nested comp is used somewhere you forgot about?
✓ Reducer: Dependency checking + undo safety net
Features
Clean up without the anxiety.
Reducer scans, analyzes, and safely removes what you don't need.
Unused Footage Detection
Scans your entire project and identifies footage items, images, and audio files not used in any composition. See exactly what's wasting space.
Safe Deletion with Undo
Every cleanup action can be undone with a single click. Reducer never permanently deletes source files from your disk, only from the project.
Comp Dependency Checking
Before removing any comp, Reducer traces its entire dependency tree. If it's used anywhere, even deeply nested, you'll be warned before deletion.
File Size Analysis
See a breakdown of how much space each category of unused assets is consuming. Footage, comps, and solids, all measured and sorted by size.
Batch Cleaning
Select all unused items at once or cherry-pick individual assets. Clean an entire category with one click or go item by item for full control.
Backup Creation
Optionally save a backup of your project before cleaning. One-click rollback if you change your mind, even after saving and reopening.
Deep Dive
See how it works.
Smart scanning, safe deletion, and peace of mind.
Smart Scan
Find every unused asset in seconds.
Reducer traverses your entire project tree (every comp, precomp, and nested layer) to build a complete map of what's used and what's not. Results appear instantly.
- Scans footage, comps, solids, and audio
- Checks nested precomp dependencies
- Color-coded results: used vs. unused
- Sort by size to prioritize big savings

Dependency Tree
Never accidentally break a comp.
Before removing any composition, Reducer checks if it's referenced anywhere in your project. The visual dependency tree shows exactly what depends on what.
- Full parent-child composition mapping
- Warnings for in-use nested comps
- Safe items highlighted in green
- Protected items cannot be deleted

Auto-Backup
Clean with confidence. Rollback anytime.
Before any cleaning operation, Reducer can save a timestamped backup of your project file. If anything goes wrong, restore in one click.
- Timestamped .aep backup files
- One-click restore from the panel
- Optional: auto-backup before every clean
- Backup history with size comparison

FAQ
Frequently Asked Questions
Reducer is designed with safety as the top priority. It only removes items from the After Effects project file and never deletes source files from your hard drive. Plus, every clean operation can be undone, and optional auto-backup saves a copy before any changes.
Yes. Reducer integrates with After Effects' undo system. You can undo the cleanup immediately after running it. Additionally, if you have auto-backup enabled, you can restore from the backup at any time.
Reducer detects unused footage (video, images, audio), unused compositions (including precomps), and unused solids. It scans the entire project tree including nested precomps to ensure accuracy.
Absolutely. Reducer builds a full dependency tree before flagging anything as unused. A precomp is only marked as unused if it is not referenced by any other composition in the project, no matter how deeply nested.
Yes. Reducer is included with your Filmit Studio subscription at no extra cost. Install it from the Studio, and all future updates are delivered automatically.
