ReTrack 2 – After Effects Plugin

Tracking motion in Adobe After Effects is an essential skill for visual effects artists, compositors, and motion designers. While After Effects offers built-in tracking tools, they often struggle with complex shots or incomplete tracking data. This is where ReTrack 2 comes in—a powerful motion tracking and editing plugin designed to rebuild, refine, and enhance existing tracked data with precision. In this guide, we’ll explore the features of ReTrack 2 and how you can use it to improve your workflow.

What is ReTrack 2?

ReTrack 2 is a motion-tracking enhancement plugin for After Effects that allows users to rebuild and refine tracked data from various sources. Unlike traditional tracking tools, ReTrack 2 works on top of existing tracking data, making it easier to fix errors, refine movements, and reconstruct missing parts of a tracked motion. The plugin supports multiple types of tracked data, including:

• Standard After Effects tracker points
• Masks and mask tracking data
• Mocha tracking data
• Face Track Points effect
• Layer transform properties
• 3D camera tracking points

With its specialized tools, ReTrack 2 gives users the ability to improve tracking accuracy and work more efficiently on challenging shots.

Key Features of ReTrack 2

1. Auto Rebuild Tool

One of the most powerful features of ReTrack 2 is the Auto Rebuild Tool, which allows users to reconstruct tracked motion from incomplete or inaccurate data. This is particularly useful when dealing with motion blur, occlusions, or when tracking gets lost mid-sequence. The plugin provides two primary rebuilding methods:

• Between Position: Ideal for horizontal and vertical movement tracking. This method estimates missing tracking data between two known positions, smoothing out the motion.
• Perspective: Suitable for cases where scale, rotation, or perspective changes occur. This method is more advanced and can handle complex motion reconstructions.

2. Track Tool

The Track Tool allows users to load various types of tracked data into ReTrack 2, making it possible to work with 3D camera tracking points, tracked masks, and Mocha data. This tool is particularly useful for:

• Rebuilding incomplete tracking data by selecting and refining specific points.
• Estimating and reconstructing missing or unreliable tracking information.
• Retracking objects that move offscreen or experience tracking loss.

Using this tool, users can generate a refined point cloud of tracked data, enabling more accurate and stable motion tracking.

3. Edit Tool

The Edit Tool provides a virtual keyframing system that works above the existing tracked keyframes. Instead of modifying each keyframe individually, users can apply broader adjustments that affect the overall motion. This is incredibly useful for:

• Refining masks and rotoscoped elements
• Adjusting corner pin tracking for composited elements
• Tweaking Mocha-tracked data
• Correcting transform properties such as position, rotation, and scale

This tool helps eliminate jittery tracking and ensures smoother, more natural motion for all tracked elements.

How to Use ReTrack 2 in After Effects

Step 1: Installation

To get started, purchase and download ReTrack 2 from aescripts.com. Follow the installation instructions provided to integrate it into After Effects.

Step 2: Preparing Your Footage

• Import your video footage into After Effects.
• Create a new composition and trim your footage if necessary.
• Apply an initial tracking pass using After Effects’ built-in tracker, Mocha, or another tracking tool.

Step 3: Using the Auto Rebuild Tool

1. Select the layer with existing tracking data.
2. Open ReTrack 2 and choose the Auto Rebuild Tool.
3. Select the appropriate method (Between Position or Perspective).
4. Let ReTrack 2 process the data and refine the tracking points.
5. Apply the rebuilt tracking data to your layer.

Step 4: Enhancing Tracking with the Track Tool

1. Load the tracked data into ReTrack 2.
2. Use masks to isolate specific areas that need better tracking.
3. Rebuild missing or unstable tracking points.
4. Export the refined tracking data to a null object, mask, or corner pin.

Step 5: Refining Motion with the Edit Tool

1. Select the tracked layer or effect property.
2. Open the Edit Tool in ReTrack 2.
3. Use the virtual keyframe system to adjust the motion without affecting individual keyframes.
4. Fine-tune the motion to eliminate any unnatural movements or jitter.

Step 6: Applying and Exporting

Once the tracking data has been refined, you can apply it to:

• Masks for improved rotoscoping
• Corner pin tracking for screen replacements
• Transform properties to stabilize footage
• Tracker points for precise motion matching

Pro Tips for Getting the Best Results

• Use High-Quality Footage: Good tracking starts with clear, high-resolution footage with minimal motion blur.
• Combine Tools: Use After Effects’ built-in tracking tools alongside ReTrack 2 to achieve the best results.
• Refine in Steps: Instead of trying to fix all tracking issues at once, use multiple passes to gradually refine the data.
• Leverage Mocha Data: If you’re using Mocha for planar tracking, importing that data into ReTrack 2 can help refine and enhance it.
• Save Different Versions: Keep multiple versions of your tracking data to compare results and revert if necessary.
