I'd be happy to help you with your feature request for Fast Video Downloader.

Feature Request: Add an option to adapt the video preview quality if system is not fast enough to handle HD video.

I understand that sometimes users may encounter issues with high-quality video previews due to their system's limitations. This feature would allow users to adjust the preview quality according to their system specifications, ensuring a smoother experience.

Implementation Suggestions:

1. Add a new setting in the program's settings menu allowing users to select from different preview quality options (e.g., Low, Medium, High, Auto).

2. Implement a detection mechanism to determine the user's system specifications (CPU, GPU, RAM, etc.) and automatically adjust the preview quality accordingly.

3. Provide an option for advanced users to manually set the preview quality based on their specific system requirements.

Benefits:

1. Improved user experience: By allowing users to adapt the video preview quality, they can ensure a smooth experience even with lower-end systems.

2. Increased compatibility: This feature would make Fast Video Downloader more accessible to users with less powerful hardware, enabling them to enjoy high-quality videos without issues.

3. Enhanced flexibility: Users would have more control over their video playback experience, allowing them to adjust the preview quality according to their needs.

I hope this feature request and implementation suggestion meet your requirements! Let me know if you need any further assistance.
