Save time when working with duplicated compositions in Adobe After Effects!

This free script is a simple and convenient tool that synchronizes the Start Time of layers between an original composition and its duplicate.

No more manually adjusting layer timing one by one. Let the script handle it for you in just a few clicks!
The FREE version has no time limitations.

✨ Features

• Start Time Synchronization — matches the Start Time of layers in the duplicate composition to the original.

• Automatic Layer Count Check — verifies that both compositions contain the same number of layers before synchronization.

• Locked Layer Support — locked layers in the destination composition are automatically skipped.

• Bilingual Interface — supports English and Russian, with automatic language detection and manual switching.

⚙️ FREE Version Limitations

• Synchronizes only one pair of compositions per operation.

• Synchronizes Start Time only.

• Does not synchronize In Point or Out Point.

• Both compositions must have the same number of layers.

🖥️ Installation Instructions

1. Download the DubSyncCloneAE .jsxbin file.

4. Locate and select the downloaded .jsxbin file.

5. Click Open to launch the script.

The script interface will appear as a separate window.

🚀 How to Use

Step 1. Assign the Original Composition

1. Find your original composition in the Project panel.

2. Select exactly one composition.

3. Click Set as original in the script interface.

4. The assigned composition name will appear in the interface.

Step 2. Select the Duplicate Composition

1. Return to the Project panel.

2. Select the duplicate composition you want to synchronize.

3. Make sure the original composition is not included in the selection.

You can also select a precomposition layer inside another composition. The script will automatically identify its source composition.

Step 3. Start Synchronization

1. Return to the Track Sync interface.

2. Click Sync.

3. The script checks the selected compositions.

4. If both compositions have the same number of layers, synchronization starts automatically.

Step 4. Check the Result

The script copies Start Time values by layer order:

• Layer 1 → Layer 1

• Layer 2 → Layer 2

• Layer 3 → Layer 3

Layers are matched by their index, not by their names.

After synchronization, you will see a confirmation message. Locked destination layers are skipped automatically, and the script reports how many layers were skipped.

You can undo synchronization using Ctrl+Z (Windows) or Cmd+Z (macOS).

🌍 Language Switching

The script automatically detects the After Effects interface language:

• Russian After Effects → Russian interface.

• Other language settings → English interface.

You can switch between Russian and English at any time by clicking Language: EN / Язык: RU. Restarting the script is not necessary.

⚠️ Additional Usage Notes

• Assign the original composition before clicking Sync.

• Select only one duplicate composition per operation.

• Both compositions must have the same number of layers.

• Layer synchronization is performed by layer index, not layer name.

• Only one original composition can be assigned at a time.

• If multiple duplicate compositions are selected, the script displays a message explaining the FREE version limitation.
