Boris FX SynthEyes 2025.5

SynthEyes 2025.5 is standalone tracking software for motion capture, live-action compositing of CG characters, and 3D set augmentation.

Specializing in camera, object, geometry, planar tracking, stabilization, and motion capture, SynthEyes is feature-rich, can export tracking data to a wide range of applications, and is available at a very reasonable price.

SynthEyes can be used for a variety of applications including inserts, shake correction, virtual sets, object removal, stereoscopic production, 360° VR, architectural previews, accident reenactments, product placement, face and body capture, and more.

In development since 2003, SynthEyes is used by VFX artists worldwide.

• Flexible Lens Workflow Export : Lens distortion correction is automatically applied on export, providing consistent, distortion-safe results across all platforms.
• ML Motion Estimation : Uses machine learning to generate accurate motion vectors, improving track quality and reducing manual correction.
• Mesh and Tracker Parenting : Link meshes to trackers with one click, making it easier to align objects and maintaining the relationship even after export.
• Other enhancements include expanded mask controls, automatic video rotation handling, LUT folder organization, and support for the new Blackmagic RAW 17K codec.

Flexible lens workflow export

The Flexible Lens Workflow Export feature eliminates the need for tedious distortion management, enabling predictable and consistent output. It allows you to apply non-destructive image correction or re-distortion to each export, giving you flexible control over margins, resolution, and compatibility with downstream processes, all while keeping your project intact.

• Unified output behavior : Apply Undistort/Redistort only when and where needed, without requiring any fixed changes to the scene.
• Non-destructive workflow : freely change and rewind distortion settings for each export without altering the footage or solve results.
• Consistent UI design : A unified interface across all export modules allows for quick and accurate setup for each shot.

Mesh-to-Tracker Parenting

Mesh-to-Tracker Parenting is a new feature that allows you to link geometry to a solved tracker with one click. Objects will always maintain their relative positions even when your project is updated with tracking or lens adjustments, eliminating the need for manual repositioning or corrections.

• One-click linking : Instantly snap meshes to trackers in the viewport, with automatic pivot placement.
• Maintained across solves : Links are maintained even after distortion, scaling, and reconstraints.
• Can be exported as is : The link structure can be output as is to 3D software or compositing apps.
• Pivot and offset can also be edited : Freely adjust the position, rotation and scale of the mesh while maintaining the link.

Innovations in Object Tracking and Masking

Mask ML leverages advanced machine learning to dramatically reduce manual rotoscoping. With intuitive object selection, Mask ML instantly generates accurate, edge-aware masks for multiple objects and complex shapes, resulting in clean 2D tracking and superior 3D solving, freeing artists to focus on their creative work.

• Instant Mask Creation: Click or drag to instantly generate precise, edge-aware masks.
• Faster multi-object masking: Mask multiple objects simultaneously to work faster.
• Roto Panel Integration: Automatically add each mask as a separate layer for organized compositing.
• Batch processing: Process multiple shots in the background, freeing you to focus on your creativity.

A new approach to workflow optimization

The Workflow Presets Manager in SynthEyes 2025 replaces the traditional environment system with a new hierarchical preset structure for more efficient and flexible workflow management. Organized into four levels - Built-in, Facility, User, and Scene - it speeds project setup while still allowing for advanced customization.

• Faster project setup: Apply comprehensive presets, including lens distortion correction models, export settings, viewports, and more, to launch new projects faster.
• Unified team workflow: Standardize settings across facilities and teams while allowing fine-tuning for each scene, flexibly adapting to diverse project requirements.
• Increased visibility and control: Monitor and adjust preset application to minimize errors and improve workflow accuracy.
• Project Selector: Save your current preferences as a preset and reuse it in future projects, reducing setup time and preventing mistakes.

Optimize file management with dynamic tags

SynthEyes' new Project Tag Manager enables a new approach to file management. By leveraging dynamic tags, you can automatically generate folder paths for scenes, exports, and other assets, maintaining a consistent structure across your projects. This powerful tool reduces the need for manual folder management and improves workflow efficiency.

• Centralized Project Structure: Automatically create and maintain a unified folder structure for all project assets.
• Set custom export paths: Easily set dedicated paths for different exporters and output formats.
• Streamline your workflow: Eliminate the need to manually enter paths and ensure consistent file management.

Lens Calibration

SynthEyes not only calculates distortion during analysis, but also has a wide range of tools for lens calibration from lens grids. Rectify Lens Grid is used to correct unmodeled lens distortion, especially for complex lens types. It also detects and corrects tilt if grid spacing and camera-to-grid measurements are available. The Lens Master Calibration system supports linear, inverse linear, anamorphic lenses, and four types of fisheye lenses.

• Rectify Lens Grid for distortion correction
• Calibration of various lens types
• Calibration methods including random dot calibration
• Lens Distortion Presets for Different Workflows

Stabilize

SynthEyes offers stabilization of regular or 360VR footage, including 3D analytical stabilization and creation of a physical rig for export.

• Stabilization is built into the image preprocessor for both regular footage (with lens distortion) and 360VR footage.
• Stabilization with full 3D analysis or 2D tracking data
• Manual adjustments as needed
• Auto zoom mode
• Stabilization Rig Creator for non-360VR footage creates the physical equivalent of stabilization, allowing downstream 3D packages to perform the actual stabilization.
• Export 360VR stabilization data directly to applications like After Effects, Fusion, and Hitfilm
• Set up 360VR stabilization as animated textured sphere for alternative export
• Resampling to other output resolutions and aspect ratios

ViewShift System

Use ViewShift for complex object removal, merging split takes, generating animated texture maps, and more.

• Camera Mapping and Rendering System
• Uses match-moved 3D camera paths and set models
• Remove objects not only on planes but also on various reflector meshes
• Quick setup tool for working from clean plates
• Lighting correction for accurate matching
• Multiple Timing Modes
• Controlling animated splines or mesh outlines
• Various output modes for preview and compositing
• Matte generation with softening
• Animated texture maps from meshes
• Multiple independent ViewShift outputs

Scripting

Get language control with Synthia, SynthEyes' chat-style assistant. Automate frequent tasks using Synthia, Sizzle, and Python scripting.

• Use the native Sizzle scripting language or the Python API/SDK
• Synthia assistant converts everyday language into powerful scripting commands
• Modify and extend the functionality of SynthEyes with scripting, including access to scene and image preprocessing
