<246MB Video files on SD Card

I saw that 68GB is used… I placed the card in my card reader and there are so many short video files on it. The files have a max size of 246MB and show only a part of the print if it was a longer print.

For what are these files? Did I active a function and I didn’t know it?

Its just n opt out setting, out of the box.
