Video stabilization using gyroscope data

Homepage •Download •Documentation •Discord •Report bug •Request feature

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

• 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 ontelemetry-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)

• For cameras which do have built-in gyro, please contact us and we will implement support for that camera. Refer to thedocumentation 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 anAtomS3). You just have to mount it on your main camera.

• 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 andhttps://cheats.rs/
• For the UI stuff, there's a nice QML book by The Qt Company:https://www.qt.io/product/qt6/qml-book

Gyroflow is written inRust, with UI written inQML. It usesQt,ffmpeg,OpenCV andmdk-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 andsrc/core/synchronization/opencv.rs). Core algorithms and undistortion don't use OpenCV.

GPU stuff supportsDirectX,OpenGL,Metal andVulkan thanks toQt RHI andwgpu.For GPU processing we useOpenCL orwgpu, with highly parallelized CPU implementation as a fallback.

1. Entire GUI is in thesrc/ui directory
2. src/controller.rs is a bridge between UI and core, it takes all commands from QML and calls functions in core
3. src/core contains the whole gyroflow engine and doesn't depend onQt orffmpeg.OpenCV is optional
4. src/rendering contains all FFmpeg related code for rendering final video and processing for synchronization
5. src/core/gpu contains GPU implementations of the undistortion
6. src/qt_gpu contains zero-copy GPU undistortion path, using Qt RHI and GLSL compute shader
7. src/gyroflow.rs is the main entry point
8. mod.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)

Visual Studio Code withrust-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 changelive_reload = true ingyroflow.rs and it should work right away. Now every time you change any QML file, the app should reload it immediately.
