#4934 Target video duration is 0: F:/win-videotrans-v3.83/tmp13016/d3188577a1/novoice.mp4

The error "Target video duration is 0" indicates that FFmpeg or the software could not read a valid video stream from the temporary file novoice.mp4. This usually happens when:

• The original input video was corrupted or had zero duration.
• The software's temp directory (tmp13016) ran out of disk space or the file was not fully written.
• The file path contains unsupported characters (though in this case the path looks clean).

Recommended steps:

1. Check the original video file – Open it in a media player to confirm it has a non-zero duration and contains a video track.
2. Free up disk space – Ensure the drive where F:/win-videotrans-v3.83/ resides has enough free space (at least several gigabytes).
3. Run again with "Clean generated" enabled – In the main window, check the 清理已生成 (Clean Generated) box before starting the task to force reprocessing from scratch.
4. If using a long/unnatural video name, rename the original video to a short English name (e.g., test.mp4) and place it in a shallow folder (e.g., D:\videos\test.mp4).

If the problem persists, please provide the latest log file (about the last 30 lines) from the logs/ folder inside the software installation directory. This will help identify whether FFmpeg is failing or the source file is genuinely invalid.
