## Where can I ask questions?
You can get support and ask all questions on [**Discord**](https://discord.gg/YaUtNpWTUh).
## Forcefully Reset Settings
Because Gyroflow development moves fast, and the software is constantly being updated and improved, it's possible that your Settings files can get corrupted, or contain bad data between updates. If Gyroflow fails to open, or you're having crashes on launch, you can try forcefully trashing your settings, to give Gyroflow a fresh slate:
{% tabs %}
{% tab title="Mac" %}
Open the `Terminal.app` and enter the following command:
`rm -f "$HOME/Library/Application Support/Gyroflow/settings.json"`
{% endtab %}
{% tab title="Windows" %}
1. Open file explorer and enter this address: `%localappdata%/Gyroflow`
2. Delete the `settings.json` file
{% endtab %}
{% tab title="Linux" %}
Open Terminal and enter:
`rm -f $HOME/.config/Gyroflow/settings.json`
{% endtab %}
{% endtabs %}
## GPU encoding is not available or not working
Support for codecs and modes varies greatly between GPU brands and models, for more information refer to specific guides for [NVIDIA](https://docs.gyroflow.xyz/app/hardware-acceleration/nvidia), [AMD](https://docs.gyroflow.xyz/app/hardware-acceleration/amd), [Intel](https://docs.gyroflow.xyz/app/hardware-acceleration/intel), [macOS ](https://docs.gyroflow.xyz/app/hardware-acceleration/apple-macos)or [Android](https://docs.gyroflow.xyz/app/hardware-acceleration/android). If you don't know what GPU you have, refer to your computer specifications.
**Always make sure you have the latest GPU driver.**
If your computer is older than 2016, chances are H.265/HEVC will not be available, and if it's older than 2012, H.264 may also not be available.
H.264 doesn't support 10-bit GPU encoding, and ProRes is accelerated only on M1/M2 macs.
## I'm using O3 Air Unit and I have a lot of vibrations after stabilizing
Read more [**in the DJI section**](https://docs.gyroflow.xyz/app/supported-cameras/dji#dji-o3-air-unit-vibration-issues).
## I see only black screen when stabilization is enabled.
Most likely you have **Fixed camera** method selected in the Stabilization section. Change to **Default** or use **Advanced -> Reset all settings to defaults** (on the bottom right)**.**
## I'm getting a crash when trying to export and I'm using macOS with Intel processor
Go to **Advanced -> Device for video processing** and select one starting with **\[wgpu]**
## **I'm having trouble stabilizing a RunCam camera**
Refer to the [**RunCam section**](https://docs.gyroflow.xyz/app/getting-started/supported-cameras/runcam). Make sure to learn the synchronization process by reading [**🔧 Basic usage**](https://docs.gyroflow.xyz/app/getting-started/basic-usage), [**📈 Timeline and gyro chart**](https://docs.gyroflow.xyz/app/getting-started/basic-usage/timeline-and-gyro-chart) and [**⌛ Synchronization**](https://docs.gyroflow.xyz/app/getting-started/basic-usage/synchronization).
## Colors are changed after exporting from Gyroflow
Read about this issue on the [**🎨 Color differences**](https://docs.gyroflow.xyz/app/advanced-usage/color-differences) page.
## My video is zoomed in too much
Make sure to use **Default** algorithm in the Stabilization section. Read more on the [**🔥 Stabilization**](https://docs.gyroflow.xyz/app/getting-started/basic-usage/stabilization) page.
## I'm seeing black bars around my video
Enable **Dynamic zooming** in the Stabilization section.
## How to export vertical video?
Go to **Export settings**, uncheck the lock icon and enter 9:16 resolution there, e.g. 1080x1920. Read more on the [**🎬 Exporting**](https://docs.gyroflow.xyz/app/basic-usage/exporting#output-size) page.
## When I run the program on Windows, there's an icon on taskbar but no window appears
Most likely the window is shown outside of your monitor. You can Shift+Right click on the taskbar icon, and select **Maximize** to bring the window back to the visible area.
## What logging rate should I use?
**50Hz** is the absolute minimum.
For reference:
* GoPro uses **200Hz**
* DJI & Insta360 uses **1000Hz**
* Sony uses **2000Hz**
## Is there a way to rotate video in Gyroflow?
Yes, you can rotate in the **Video Information** panel. There's an editable field called **Rotation**.
Simply click the little blue pencil icon, then adjust the rotation value as required.
