Variable Frame Rec

Shooting in this mode allows you to obtain smooth slow
motion or quick motion videos.
Using different frame rate settings for recording and
playback, videos captured at normal speed can be played
back more smoothly than those in low or high speed
playback.

required at the same time.
● [Camera Resolution] in the [Record Format] menu is set to
A1280x720B.
● [Frame & Bit Rate] in the [Record Format] menu is set to
