A VID file is a generic video file that has been saved in one of many possible video file formats. Often, the file’s extension has been changed from its original extension to . vid. For example, a user might have renamed a file like clip1.
How do I view a vid file on my Android?
vid is a container. You need to find out the actual video codec used. Maybe paste the first 64 bytes (or more) of the file into your question. You can copy the bytes values from a hex editor (get a free one or use an online hex viewer).
