About recording
You can record each of the channels on Pearl-2 as AVI, MOV, MPEG-TS, MP4, or MP4-Fragmented. You can
also setup multi-track recorders, see Recorders.
Recording using Pearl-2 is robust. If an accidental system shutdown occurs while recording is in progress, your
recordings are gracefully closed off so they are still playable.
Physically unplugging a video source from the input port or otherwise interrupting the signal does not stop
recording. A No Signal image is inserted.When recording auto channels, a new recording is made when the
input changes from one to another due to signal loss. When recording a multi-channel recorder or a multi-
source layout channel, a new file is created if an additional source is added to the recorder.
Easily stop and start recording using any of the user interfaces:
l Admin panel
l Touch screen
l Epiphan Live
To learn how to use Epiphan Live to control recording, see Control streaming and recording. To control
recordings remotely, see Control recording using AV Studio
Using the One Touch feature, you can control recording of all your channels and recorders with a single tap on
the touch screen, see About One Touch streaming and recording.
Pearl-2 comes with APIs so you can setup third party tools to control recording, see Controlling Pearl-2 using
HTTP/HTTPScommands and Controlling Pearl-2 using RS-232 / serial port.
Each channel or recorder has a maximum time or file size limit setting that you can configure using the Admin
panel. The default recording limits are set to 30 minutes or 500 MB, whichever comes first. When the time or
file size limit is reached, the current recording is saved and a new recording file starts automatically without
losing any content.
Newer recordings overwrite oldest recordings when the hard drive is full.
