How to handle dual subtitles, and why only one soft subtitle is displayed

In the "Embed Subtitles" dropdown menu, you can select "Hard Subtitle Embedding (Dual)" or "Soft Subtitle (Dual)". In the resulting video, both the original language and the target language subtitles will be retained. Hard subtitles will be displayed in two lines (top and bottom), while soft subtitles will only display one language. If you want to display the other soft subtitle, please use the subtitle management function of your video player to switch.
