#7710 Video file selection required

The error indicates no video/audio file has been selected before starting the task — the first row Select Video/Audio is a mandatory field.

Solutions:

1. Click the Select Video/Audio button (top-left) and choose a valid file (mp4/mkv/avi/mov/wav/mp3, etc.).
2. If you want to batch-process a whole directory, check the Folder option after selecting the folder.
3. Verify the selected file is not corrupted and actually contains an audio track (a video without a human voice track cannot be processed).
4. Once a file appears in the file list, click Start again.

Additional note about your install path:
Your software is located at C:/Users/Al Madina Computer/Desktop/win-pyvideotrans-v4.14(1). This path contains spaces, parentheses and is on the system/Desktop directory, which frequently causes failures. It is strongly recommended to move and extract the software to a simple all-English/number path without spaces or special symbols, e.g. D:\pyVideoTrans.
