About the project
Gyroflow is an application that can stabilize your video by using motion data from a gyroscope and optionally an accelerometer. Modern cameras record that data internally (GoPro, Sony, Insta360 etc), and this application stabilizes the captured footage precisely by using them. It can also use gyro data from an external source (eg. from Betaflight blackbox).
Features
- Real time preview, params adjustments and all calculations
- GPU processing and rendering
- Fully multi-threaded
- Rolling shutter correction
- Supports already stabilized GoPro videos (captured with Hypersmooth enabled) (Hero 8 and up)
- Supports and renders 10-bit videos (and higher, up to 16-bit 4:4:4, direct YUV rendering with no data loss - no conversion to RGB)
- Visual chart with gyro data (can display gyro, accel, magnetometer and quaternions)
- Visual display of smoothed quaternions
- Real time offset adjustments
- Two optical flow methods
- Two offsets calculation methods
- Modern responsive user interface with Dark and Light theme
- Adaptive zoom (dynamic cropping)
- Based on telemetry-parser - supports all gyro sources out of the box
- Gyro low pass filter, arbitrary rotation (pitch, roll, yaw angles) and orientation
- Multiple gyro integration methods for orientation determination
- Multiple video orientation smoothing algorithms, including horizon levelling and per-axis smoothness adjustment.
- Cross-platform - currently works on Windows/Linux/Mac, with Android and iOS apps coming
- Multiple UI languages
- Supports variable and high frame rate videos, all calculations are done on timestamps
- x264, x265, ProRes and PNG outputs, with x264 and x265 fully GPU accelerated
- Automatic lens calibration process
- Fully zero-copy GPU preview rendering is possible, implemented and almost working (😀)
- Core engine is a separate library without external dependencies (no Qt, no ffmpeg, no OpenCV), and can be used to create OpenFX and Adobe plugins (on the TODO list)
- Automatic updates of lens profile database
- Built-in lens profiles for GoPro HERO 6, 8, 9 and 10 in all shooting modes

Info for cameras not on the list
- For cameras which do have built-in gyro, please contact us and we will implement support for that camera. Refer to the documentation for information about the gyro logging process.
- For cameras which don't have built-in gyro, please consider using Betaflight FC or check out our flowshutter project.

I want to contribute but I don't know Rust or QML
- The Rust book is a great way to get started with Rust: https://doc.rust-lang.org/book/
- Additional useful resources for Rust: https://quickref.me/rust and https://cheats.rs/
- For the UI stuff, there's a nice QML book by The Qt Company: https://www.qt.io/product/qt6/qml-book
Development
Used languages and technologies
Gyroflow is written in Rust, with UI written in QML. It uses Qt, ffmpeg, OpenCV and mdk-sdk external dependencies for the main program, but the core library is written in pure Rust without any external dependencies.
OpenCV usage is kept to a minimum, used only for lens calibration and optical flow (src/core/calibration/mod.rs
and src/core/synchronization/opencv.rs
). Core algorithms and undistortion don't use OpenCV.
GPU stuff supports DirectX, OpenGL, Metal and Vulkan thanks to Qt RHI and wgpu. For GPU processing we use OpenCL or wgpu, with highly parallelized CPU implementation as a fallback.
Code structure
- Entire GUI is in the
src/ui
directory src/controller.rs
is a bridge between UI and core, it takes all commands from QML and calls functions in coresrc/core
contains the whole gyroflow engine and doesn't depend on Qt or ffmpeg, and OpenCV is optionalsrc/rendering
contains all FFmpeg related code for rendering final video and processing for synchronizationsrc/core/gpu
contains GPU implementations of the undistortionsrc/qt_gpu
contains zero-copy GPU undistortion path, using Qt RHI and GLSL compute shader, but this method is experimental and buggy for nowsrc/gyroflow.rs
is the main entry pointmod.rs
orlib.rs
in each directory act as a main entry of the module (directory name is the module name andmod.rs
is kind of an entry point)
Dev environment
Visual Studio Code
with rust-analyzer
extension.
For working with QML I recommend to use Qt Creator and load all QML files there, as it has auto-complete and syntax highlighting.
The project also supports UI live reload, it's a super quick way of working with the UI. Just change live_reload = true
in gyroflow.rs
and it should work right away. Now every time you change any QML file, the app should reload it immediately.
