GitHub - gyroflow/gyroflow: Video stabilization using gyroscope data

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). Trailer / results video

Features

Real-time preview, parameter adjustments and all calculations GPU processing and rendering, all algorithms fully multi-threaded Rolling shutter correction Video editor plugins (Adobe Premiere/Ae, DaVinci Resolve, Final Cut Pro and more), allowing you to apply stabilization directly in a video editor without transcoding Supports full Sony metadata (recording params, automatic lens, support for IBIS, OIS, EIS - you can have IBIS enabled in camera and still apply Gyroflow on top) Supports already stabilized GoPro videos (captured with Hypersmooth enabled) (Hero 8 and up) Supports and renders 10-bit videos (up to 16-bit 4:4:4:4 for regular codecs and 32-bit float for OpenEXR - working directly on YUV data to maintain maximum quality) Customizable lens correction strength Render queue Keyframes Ability to create custom settings presets Visual chart with gyro data (displays gyro, accelerometer, magnetometer, and quaternions, including smoothed quaternions) Supports underwater footage (corrects underwater distortions) Modern responsive user interface with Dark and Light theme Adaptive zoom (dynamic cropping) Zoom limit Supports image sequences (PNG, OpenEXR, CinemaDNG) 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 - works on Windows/Linux/Mac/Android/iOS Multiple UI languages Supports variable and high frame rate videos - all calculations are done on timestamps H.264/AVC, H.265/HEVC, ProRes, DNxHD, CineForm, PNG and OpenEXR outputs, with H.264 and H.265 fully GPU accelerated (ProRes also accelerated on Apple Silicon) Easy lens calibration process Fully zero-copy GPU preview rendering 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 official lens profiles for GoPro HERO 6-13; Sony; DJI; Insta360 action cameras; RunCam: Thumb series, 5 Orange Easy management of the video editor plugins from within the app Ability to add an additional 3D rotation (useful for framing vertical videos)

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, you can use any other device which records gyro data. It may be a phone, an action camera, or an external device like a Betaflight FC, flowshutter, esp-gyrologger (eg. on an AtomS3). You just have to mount it on your main camera.

Installation Windows - Microsoft Store or:

Download Gyroflow-windows64.zip from the Releases page, extract the files somewhere and run Gyroflow.exe If it shows an error about VCRUNTIME140.dll or 0xc0000142, install VC redist

MacOS - App Store or:

Download Gyroflow-mac-universal.dmg from the Releases page, run the downloaded file, and drag & drop Gyroflow app to the Applications folder (or anywhere you want, like on Desktop) You can also install using brew: brew install gyroflow.

To upgrade Gyroflow, run brew update then brew upgrade gyroflow

Linux

Download Gyroflow-linux64.tar.gz from the Releases page, extract the files somewhere and run ./Gyroflow in the terminal. If that doesn't work, you can try the Gyroflow-linux64.AppImage, but the .tar.gz one is preferred. Make sure you have latest graphics drivers installed Possibly needed packages: sudo apt install libva2 libvdpau1 libasound2 libxkbcommon0 libpulse0 libc++-dev libvulkan1 GPU specific packages:

Help us translate Gyroflow to your language!

We use crowdin to manage translations and you can contribute there: https://crowdin.com/project/gyroflow 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. The Gyroflow binary links against mdk-sdk, which is closed-source and not licensed under the GNU GPL. Gyroflow is licensed under GPLv3 with an additional permission allowing linking with mdk-sdk. mdk-sdk is distributed under its own license. 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 core src/core contains the whole gyroflow engine and doesn't depend on Qt or ffmpeg. OpenCV is optional src/rendering contains all FFmpeg related code for rendering final video and processing for synchronization src/core/gpu contains GPU implementations of the undistortion src/qt_gpu contains zero-copy GPU undistortion path, using Qt RHI and GLSL compute shader src/gyroflow.rs is the main entry point mod.rs or lib.rs in each directory act as a main entry of the module (directory name is the module name and mod.rs is kind of an entry point)
