    What SD-Card are you using? – flolilo Mar 9 '18 at 14:29

You are probably shooting a video snapshot instead of a movie. Their length is selectable between 2, 4, and 8 seconds. That would mean you can't shoot photos without first disabling video snapshots in the menu.

To shoot a movie, set your power switch to the video camera symbol.
