Starting recording returns the MVF-2 as well as the side display to their HOME screen and disables
access to sensor fps, timecode, shutter, exposure index, auto white balance, erase media, playback
and most menu settings.
12.5 Prerecording
Prerecording writes images into an internal ring buffer for up to 20 seconds in real time instead of
recording them directly to the recording medium. When regular recording starts, the buffered images
are written to the recorded clip. This allows unpredictable events to be captured without wasting media
capacity. The maximum available duration of Prerecording is determined by the set combination of
sensor frame rate, recording codec and sensor mode, but can also be set by the user within these
limits.
Prerecording can only be started and stopped using a user button assigned with
Prerecording
.
► Select
MENU > User Buttons
and assign
Prerecording
to the desired button.
► Press the user button to start Prerecording.
► Press the user button again to end Prerecording or press the
REC
button to start regular recording.
Info:
When ending Prerecording, the ring buffer is cleared.
Info:
While Prerecording is active, timecode, shutter, exposure index, auto white balance, erase
media, playback and most menu settings cannot be accessed. The sensor frame rate can be
changed during Prerecording, but this will clear the ring buffer.
Setting the Prerecording Duration
► Select
MENU > Recording > Prerecording max. Duration
and set the maximum duration used for
Prerecording in a range from
1
to

seconds.
The available Prerecording duration depends on the set Codec, Sensor Mode and Recording
