[Variable Frame Rate]

By recording using a frame rate that is different to the playback frame rate, you can record smooth slow motion video and fast motion video.

Slow Motion Video (Overcrank Recording) | Set a number of frames that is higher than the recording frame rate of the [Rec Quality]. For example: When recording at 48 fps and set to a 24.00p [Rec Quality], the speed is halved.
Fast Motion Video (Undercrank Recording) | Set a number of frames that is lower than the recording frame rate of the [Rec Quality]. For example: When recording at 12 fps and set to a 24.00p [Rec Quality], the speed is doubled.
