Menu item details
-
Record Setting:
- Selects the frame rate of the movie from [60p 50M]/[50p 50M], [30p 50M]/[25p 50M], and [24p 50M]*.
*Only when [NTSC/PAL Selector] is set to NTSC.
-
Frame Rate:
- Selects the shooting frame rate from [240fps]/[250fps], [480fps]/[500fps], and [960fps]/[1000fps].
- This setting determines the minimum shutter speed per frame.
-
Priority Setting:
- Select [Quality Priority] or [Shoot Time Priority]. If you select [Shoot Time Priority], the recordable duration is longer than in [Quality Priority] mode.
-
REC Timing:
- Selects whether to record a set amount of time after pressing the SHUTTER/MOVIE button ([Start Trigger]), or to record for a set amount of time until you press the SHUTTER/MOVIE button ([End Trigger]).
Frame rate
In super-slow-motion movie shooting, the camera shoots at a faster shutter speed than the number of shooting frames per second. For example, when [Frame Rate] is set to [960fps], the shutter speed per frame will be faster than approx. 1/1000 second in order to shoot 960 frames per second. To maintain this shutter speed, sufficient ambient light is necessary during shooting. If the ambient light is insufficient, the ISO sensitivity will become higher, resulting in more noise.
Timing of recording
Depending on the [REC Timing] setting, the relationship between when you press the SHUTTER/MOVIE button and the recorded section of the movie is as shown below.
: The point when the SHUTTER/MOVIE button is pressed
: Recorded section
: Recording to memory card in progress (You cannot start the next session of shooting while the camera is recording to the memory card.)
: Buffering in progress
- [Start Trigger]
-
Movie capturing (shooting) starts when the SHUTTER/MOVIE button is pressed. When the SHUTTER/MOVIE button is pressed again, or when the recordable duration of time has elapsed, movie capturing ends and the camera starts to record the captured movie to the memory card.
- [End Trigger]
-
Buffering (temporarily capturing a movie on the camera) starts once the shooting standby screen is displayed. When the captured data fills the buffering capacity, old data is overwritten sequentially. When you press the SHUTTER/MOVIE button, the camera starts to record a movie of the maximum recordable duration calculated retroactively from that point on the memory card.
To redo shooting
You can cancel recording by selecting [Cancel] on the screen. However, the movie recorded up to the point you cancelled will be saved.
Playback speed
The playback speed will vary as below depending on the assigned [Frame Rate] and [Record Setting].

Playback time
For example, if you shoot for approx. 4 seconds with [Record Setting] set to [24p 50M]*, [Frame Rate] set to [960fps], and [Priority Setting] set to [Shoot Time Priority], the playback speed will be 40 times slower and the playback time will be approx. 160 seconds (approx. 2 minutes and 40 seconds).
*Only when [NTSC/PAL Selector] is set to NTSC.
