No subtitles with quicktime player, though I can see them using VLC, why?

I have a m4v file which contains both subtitles and audio languages...


...I can use both subtitles and audio tracks by watching it using VLC


...but I lose subtitles when I play the same file with QuickTime Player


Any reason? What I can I do?

MacBook Pro, macOS High Sierra (10.13.6)

QuickTime Player requires a special subtitle format (Tx3g), while VLC is much more flexible in supported subtitle formats.

A remuxer like Subler can convert the file with embedded subtitles to a compatible .mp4 format, in most cases.
