I want to record the small details in a video, how do i do it with this camera?
You need to look for the "flower" symbol and select it - that is the symbol for the close up mode.
It is on the left of the "FUNC SET" button on the back...see it here:

The mountain selection is for far pictures and the flower selection is for close ups.
