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 target language subtitles. Hard subtitles will display as two lines (top and bottom), while soft subtitles will only show one language at a time. If you want to display the other soft subtitle language, use the subtitle management feature of your video player to switch.
