timer Sony Alpha A6300 Video Recording

[OmrMor]

Hello,

I've been having a problem when recording with my Sony A6300.

The problem is that every time I start recording, it automatically stops at the 20th second.  I've tried to change the settings and see if the problem has to do with that but no, I even bought Sony's sd xc I U3 64GB

 memory card and nothing has changed. I would like to know if somebody else has this problem and how it can be fixed.
