Gyroflow
Gyroflow is a gyroscope video stabilization software and IMU telemetry processor designed to remove camera shake from video files. It functions as a hardware-accelerated video renderer and lens calibration tool, utilizing embedded or external gyroscope and accelerometer data to perform pixel-level stabilization.
The system is distinguished by its ability to integrate with professional non-linear video editing software via plugins, allowing stabilization to be applied directly to timelines without transcoding original footage. It supports diverse telemetry ingestion from camera brands, flight controllers, and external sidecar files, and includes specialized tools for reversing electronic stabilization and correcting rolling shutter artifacts.
Broad capabilities include lens distortion modeling, horizon locking, and adaptive crop and zoom management. The software provides a command-line interface for programmatic batch processing, directory monitoring, and telemetry conversion, alongside GPU-accelerated encoding for high-fidelity video export.
The project provides utilities for digital lens calibration, sensor data visualization, and the generation of 3D camera motion for compositing environments.
