#4150 Permission denied: C:/Users/Solofo/Documents/test/YouTube Killed Shorts - WAN Show April 17, 2026.mp3

This error occurs because the file path contains special characters (like ?) or is too long, which is not compatible with Windows command-line operations (used by ffmpeg).

Solution:

1. Rename the file: Change the video file name to a short, simple name using only English letters, numbers, and underscores. For example, rename YouTube Killed Shorts - WAN Show April 17, 2026.mp3 to something like video.mp3.
2. Move the file: Place the renamed file in a shallow directory, such as D:\videos, instead of a deep path like C:/Users/Solofo/Documents/test/.
3. Re-select the file: In pyVideoTrans, click "Select audio or video" and choose the renamed file from the new location.

Key Points:

• Windows has a maximum path length limit (~260 characters). Long paths cause ffprobe exec error or permission issues.
• Special characters (e.g., ?, *, emojis) in filenames often cause command-line failures, especially with files downloaded from YouTube.
• Always use short, simple names and avoid deep directory structures for input files.
