FAQ – Resolving the Video Display Issue in EthoVision XT

Q: Why do my MP4 videos show only a black screen in EthoVision XT on macOS?
A: EthoVision XT is not supported on macOS. This incompatibility is the main cause of the black screen. The software is designed to run on Windows.

Step-by-step instructions

1. Switch to a Supported Operating System
   • Install and run EthoVision XT on a Windows PC.
   • macOS is not officially supported and may cause playback issues.
2. Check Video Playback on Windows
   • Update graphics drivers to the latest version.
   • If using a laptop with an external monitor, make sure EthoVision is configured to use the correct display and graphics adapter.
   • Ensure your system meets EthoVision XT’s hardware specifications.
3. Verify Video Format
   • EthoVision XT supports standard MP4 files (commonly H.264 encoded).
   • If playback still fails, convert the video to a supported format/codec (e.g., H.264 MP4) using a trusted video converter.
4. Maintain Video Confidentiality
   • All troubleshooting can be done locally on your machine.
   • You do not need to share or upload your video files, ensuring sensitive data stays confidential.

Following these steps should resolve the black screen issue and allow videos to play properly in EthoVision XT.
