24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.
Slow-motion is an artistic video effect that makes time seem to go slower. It is achieved by recording a video at a higher frame-rate than the standard playback rate of 24fps or 30fps. Frame rates for slow-motion videos vary between 60fps and 960fps.
When recording movies they stay focussed and sharp.
A timelapse shows a long passage of time sped up. A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.
The burst mode, also called serial shot mode or continuous shooting mode, allows you to shoot multiple photos in a row.
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.
