I have some questions regarding **Quick Time Player** in **macOS**.

1. *Which type of subtitle files are supported by **Quick Time Player**.*

2. *How to add a downloaded subtitle for a particular video in Quick Time Player.*

3. *In VLC, there is a **VLSub** plugin to download subtitles automatically from Internet using VLC. 
Is there any plugin or option to do the same in **Quick Time Player** ?*
