Join the Gyroflow Discord server for discussion and support.
A program built around Python, OpenCV, and PySide2 for video stabilization using gyroscope data.
The project consists of three core parts: A utility for the generation of lens undistortion preset, a utility for stabilizing footage using gyro data, and a utility for stretching 4:3 video to 16:9 using non-linear horizontal stretching (similar to GoPro's superview).
The main goal of creating something that can stabilize footage based on blackbox gyro data has mostly been achieved. Moving forwards, more work will be done to improve the quality of the result.
The launcher containing all the utilities is available by executing gyroflow.py if all the dependencies are met. Otherwise a binary can be found over in releases. Also, check out the wiki where there's some more information about the camera calibration and video stabilization process.
Note: Try the dev branch for the newest features.

- Use the settings that give the widest possible field of view (more data to work with). For a lot of cameras, this is in the 4:3 aspect ratio.
- If using the main drone flight controller for logging, the camera should be hardmounted.
- If using a secondary logger on the camera or internal camera logging, some soft mounting is preferred to isolate vibrations.
