#3784 No valid audio in C:/Users/Luon/Downloads/发现更多精彩视频_-_抖音搜索/发现更多精彩视频.mp4. Check file.

This error indicates that the software could not detect a valid audio track in the specified video file. The issue is likely due to the video file's path containing Chinese characters or special symbols, or the file itself may have no audio or extremely low audio volume.

Solution Steps:

1. Rename and Move the File:

   • Change the video file name to a short name using only English letters and numbers (e.g., video.mp4).
   • Move the file to a directory with a simple, English-only path, such as D:\videos\.
   • Crucially, ensure the software itself (sp.exe) is also installed in a path containing only English characters (e.g., D:\pyVideoTrans).

2. Check Audio Content:

   • Play the video using a standard media player to confirm it actually contains audible speech.
   • If the environment is very noisy, try enabling the "Noise Reduction" option in the software before processing.

3. Verify Language Setting:

   • In the software's main interface, ensure the "Source Language" is correctly set to match the language spoken in the video (e.g., Chinese). Do not rely on Auto.

4. Clear Cache (Optional):

   • If you have processed this file before, check the "Clear generated files" option on the main interface to force a fresh processing run.

If the problem persists after these steps, please provide the latest log file from the logs/ folder in your software installation directory (copy the bottom ~30 lines of the error message).
