Pre-Record
Even while PMD-901V is not actively recording, its buffer will record video as
long as it is powered on. If the pre-record feature is on, any video you record
will also include the video from the buffer.
In other words , once you press
the Video ( ) button to start recording, PMD-901V will include some of the
footage that it captured before you pressed the Video ( ) button.
You can activate Pre-Record in the Settings menu. See Settings to learn
how to do this.
The length of video stored in the buffer depends on the video resolution:
