#6255 Video file selection required

This error means you clicked the start button without selecting any input video or audio file.

Solution:

1. On the main "翻译视频/视频翻译" interface, click the "选择视频或视频" (Select video or audio) button and choose at least one file (supported video: mp4/mov/avi/mkv/webm/mpeg/ogg/mts/ts/wmv/flv; supported audio: wav/mp3/m4a/flac/aac/wma/ogg).
2. If you want to process a whole folder, tick the "文件夹" (Folder) checkbox and select the folder.
3. After a valid file appears in the list, click "开始" (Start).

If you are certain a file is already selected and the error still appears, please send the latest log from logs/ directory (the last 30 lines) so we can investigate further. Also confirm the exact version number shown in the upper-left corner of the software window.
