Yes. Embedded soft subtitles appear in the player's subtitle menu and can be toggled by the viewer, unlike burned-in subtitles.
No. Embedding adds the subtitle track to the container without touching the video or audio streams, so there is no quality loss and the process is fast.
You can embed multiple tracks by running the tool repeatedly. Each track should be labeled with its language for easy identification by the viewer.
