How to Handle Dual Subtitles and Why Soft Dual Subtitles Only Show One

In the "Embed Subtitles" dropdown menu, you can select "Hard Subtitles (Dual)" or "Soft Subtitles (Dual)". The resulting video will retain both the original language and the target language subtitles. Hard subtitles will be displayed as two lines (top and bottom), while soft subtitles will only show one language at a time. If you wish to display the other soft subtitle track, please use the subtitle management function of your video player to switch between them.
