ShareX: Free Screen Recording Tool & Mouse Pointer Offset Fix

This is a quick post to remind me of two things: 1) ShareX is the tool of choice for screen recordings on Windows. 2) On high-DPI (4K) screens there is a mouse pointer offset that can easily be fixed.

Capturing Screen Video Recordings With ShareX

1. Download and install ShareX.
2. Start the application. If you have another screenshot tool like Greenshot running, it may complain about not being able to register hotkeys.
3. Start the recording by clicking Capture > Screen recording or by pressing Shift+Print Screen.
4. Allow ShareX to download FFmpeg. It’ll be stored in %USERPROFILE%\Documents\ShareX\Tools
5. Select the window you want to record (ShareX highlights windows when you hover the mouse over them).
6. Perform the steps you want to record.
7. Stop the recording by clicking Capture > Screen recording or by pressing Shift+Print Screen.
8. ShareX stores the recording as an MP4 file.

Fixing the Mouse Pointer Offset on High-DPI Displays

If you’re recording on a high-DPI display, e.g., a 4K monitor, you’ll notice a mouse pointer offset: the mouse pointer is not where it’s supposed to be in the video.

This is caused by FFmpeg not being fully high-DPI aware as documented here. Luckily it can be fixed easily:

• Locate FFmpeg.exe (downloaded to %USERPROFILE%\Documents\ShareX\Tools if you followed the steps above).
• Right-click the executable and select Properties in the context menu.
• Click the Compatibility tab and select Change high DPI settings.
• Click Override high DPI scaling behavior. Scaling performed by: Application.
• The result should look similar to the screenshot above.
