A new release of the Gyroflow video stabilization system is available, working in post-processing and using data from the gyroscope and accelerometer to compensate for distortion caused by shake and uneven camera movement. The project code is written in Rust (the interface uses the Qt library) and is distributed under the GPLv3 license. Builds are published for Linux (AppImage), Windows, and macOS.
It supports both the use of a log with data from the gyroscope or accelerometer built into the camera (for example, available in GoPro, Insta360, Runcam, DJI Action, Hawkeye, Blackmagic and Sony Ξ±, FX, RX and ZV series cameras), and synchronization with data, separately received from external devices (for example, data from drones to which the camera is assigned, based on Betaflight and ArduPilot, or logs collected using mobile applications for Android / iOS). An impressive list of formats is supported for sensor data, lens profiles, imported and exported videos.
The program offers several algorithms for correcting distortion, temporal parallax and tilting of the horizon, as well as smoothing jerks from uneven camera movement. Adjustments are made through an intuitive graphical interface that provides full-resolution previews, fine-tuning of various parameters, and automatic lens calibration. Also available are a command line interface, a library with an adjustment engine, an OpenFX plugin for DaVinci Resolve, and an effect for Final Cut Pro. To speed up the processing and output of video, the capabilities of the GPU are involved.
