#7729 Video file selection required

You did not select any video/audio file before clicking Start.

pyVideoTrans requires at least one input file in the top row.

Steps:

1. Click the top-left button Select Video/Audio (第1行 "选择音频或视频").
2. In the file dialog, pick one or more files.
   
   Supported: mp4/mkv/avi/mov/wav/mp3 etc.
3. If you want to batch-process a whole directory, check the Folder box, then select the folder instead of a file.
4. Confirm the path now appears in the top row of the main window (translation video panel).
5. Click Start (开始执行) again.

Notes:

• Make sure the file path contains only simple ASCII characters (no Chinese, spaces, or special symbols), e.g.
  
  D:/pyVideoTrans/input/001.mp4.
• If you only want to transcribe/translate/dub a subtitle or text file, use the corresponding left-side panel instead: Speech-to-Text(语音转录), Translation Srt(翻译字幕), Text-to-Speech(文字配音).
