1. Introduction to Gyroflow

Gyroflow is an open-source video stabilization software that utilizes gyroscope and accelerometer data to achieve precise video stabilization, remove jelly effects, and correct lens distortion. The stabilization effect can rival that of a gimbal when there is ample lighting. Besides the standalone software, plugins for DaVinci, PR/AE are also provided to achieve lossless quality stabilization. NiYien has introduced the NiYien Tool to simplify the usage process.

2. Device Introduction and Basic Operations

2.1 Introduction

2.2 Operations

2.2.1 Button Operations

Button Description： <,>: Left/Right or Up/Down Buttons. O: Single Click to confirm, Long Press to return to the previous interface. Long press to Turn On when it is off. And on the main interface to Turn Off. The device will automatically shut down after 15 minutes of inactivity. AF/S: Two-stage button, Half Press to focus, Full Press to shutter (recording).

2.2.2 Functions and Interface Display

Main Interface: Includes Sensflow, TimeLapse, Shutter, Inclino, Settings.

Status Bar: Top left displays the current time, top right shows the memory card icon and battery indicator.

Senseflow: Displays the gyroscope recording duration in the center, lens number in the lower left corner, and focal length after setup (refer to section 5.6.2). The lower right corner shows the remaining record duration.

TimeLapse: The black box is the function selection box, where you can choose to set the wait, exposure, interval time, and number of shots.

Single Click O button to enter parameter modification mode, use the <,> buttons to select different parameters, then Single Click O key again to modify the selected parameter. Long Press O button to return to the previous function.

Shutter: Use the <,> buttons to select manual shutter mode or Bulb mode.

2.4 Gyroscope calibration

If the device has not been used for more than 3 months, it is recommended to perform calibration to achieve the best stabilization accuracy.

Calibration: In the settings, select Gyro calibration, then place the device stationary on a flat surface, such as on a table. If the calibration fails, simply try again.

2.5 Memory card reading and Formatting

Data Reading: Connect the device to the host (computer or tablet) using a Type-C cable, and device will appear as a USB drive on the host, allowing you to directly export data. For larger amounts of data, a card reader can be used.

Formatting: In the settings, select Format SD.

5.NiYien Tool Usage

The NiYien Tool integrates data for over a hundred camera models, supporting batch stabilization of horizontal shots, vertical shots, high frame rate videos, anamorphic lenses, and more.

5.1 Importing Videos

Import Videos: Click to choose and import videos,If the videos are distributed across different folders, drag the folders into the interface.

5.2 Time Synchronization and Data Allocation

1. Click to open Match Listand double-click the synchronized video.

2. Selecting Gyroscope Data to sync with the Time Synchronization Video.

3. Click Match, the gyroscope data will be automatically allocated according to the video's time, and the allocated gyroscope data will be saved locally.

    

5.3 Lens Profiles

Lens profiles can be created in three modes: auto, semi-auto,manual.

Auto: Supports Canon, Nikon, Panasonic, Sigma cameras paired with auto focus lenses. No additional settings are required, lens data is automatically extracted from the video.

Semi-auto: Requires setting the lens focal length. Six focal lengths can be set, corresponding to lens numbers 1-6 in the gyroscope. During recording, if the focal length changes, switch the lens number in the gyroscope accordingly.

Manual: Used for certain cinema cameras. Create a lens profile in the lens configuration file section and load it manually.

5.3.1 Lens Profile Generation (For Manual Mode)

View angle: The camera's frame size. In some cases, this may change, such as when a Canon full-frame camera uses an EF-S lens, switching to APS-C format. A Nikon FX full-frame camera with a crop lens switches to DX format.

Frame rate: Select the closest available option to your actual frame rate. For example, choose 60 for 59.94 fps.

Focal length:The actual focal length of the lens. If unsing a focus reduction ring, multiply the lens focal length by the reduction factor.

Frame readout time: Parameter to remove jelly effects. Some cameras provide this information directly. If not provided, refer to the video tutorial for measurement or contact NiYien official support for assistance.

5.4 Stabilization settings

5.4.1 Vertical Shooting

Niyien tool automatically recognizes it.

5.4.2 Installation direction

The default installation direction is up, for example, the hot shoe position is up (buttons facing inwards and indicator lights facing forward).

It supports installation on the left, right, and bottom.

5.4.3 Lock horizon, For FPV, Auto Rotation, Sync speed

Locking horizon: Maintains a horizon but may result in more cropping. Recommended to use with 4K and higher resolutions and wide-angle lenses.

For FPV: Check to reduce image jitter caused by high-frequency vibration of the frame.

Sync speed: Slower speed provide higher synchronization accuracy, default is medium speed.

Auto Rotation: The video will be automatically rotated to vertical mode after exporting in horizontal resolution. (Effective in Export stabilized video mode)

5.4.4 Match List and Settings

Click Match, then click Match List. You can view the matching results, hold down CTRLto select multiple rows, and right click to adjust.

Change the lens number: If you forget to adjust the lens number when shooting in semi-auto mode or manual mode, you can adjust it. Change smoothness: Multiple smoothness are available, with "Normal" being the default. You can also choose to remove jelly effects only. Change the frame rate: Enter the high frame rate used for slow-motion videos (high frame rate recording, low frame rate playback) to support stabilization of slow-motion footage.

5.5 Export

Click Export. There are two export modes.

Auto Sync for plugins:Quickly generates project files that can be viewed in Gyroflow and used in DaVinci, PR/AE plugins.

8.FAQ

8.1 In MacOS, Batch synchronization failed or videos can not loaded in gyroflow.

 

Solution: Some Mac chips have hardware decoding bugs. Disable GPU decoding to resolve this issue.

8.2 Abnormal Stabilization

Solution: Verify the following:

1. Ensure both lens and body stabilization are turned off.

2. Confirm that the time synchronization operation was performed correctly and that the synchronization video and corresponding gyroscope data were recorded simultaneously.

3. In semi-auto or manual mode, ensure the video focal length matches the lens number.

8.3 Stabilization effective but vestigial or jelly image.

Solution: This issue may be caused by heavy footsteps or low shutter speed. Lighten your steps or increase the shutter speed to 1/200 or higher.

8.4 Forgot to record time synchronization video

Solution: A time synchronization video can be recorded at any time. If you forgot, record one temporarily and copy it to the video folder. Similarly, copy the corresponding gyroscope data to the gyroscope file folder.

8.5 Success in Gyroflow but failed in DaVinci plugin

Solution: Check if adjustments have been made to parameters such as speed wave, rotation, or cropping. If adjustments exist, utilize the plugin on the Fusion page.
