About recording
You can record each of the channels on Pearl Mini as AVI, MOV, MPEG-TS, MP4, or MP4-Fragmented. You can
also setup multi-track recorders, see
Recorders .
Recording using Pearl Mini 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 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 Mini comes with APIs so you can setup third party tools to control recording, see Controlling Pearl Mini
using HTTP/HTTPS commands and Controlling Pearl Mini 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.
An SD card must be installed to record, see SD card installation and file management .
Important considerations
l
Ejecting the SD card while the recording is in progress may corrupt the SD card and cause loss of data.
Power down Pearl Mini before ejecting the SD card. Stop all recordings before powering down the
system.
l
The maximum file size cannot be larger than a quarter of the total available space on the SD card. For
example, the maximum file size limit for a 64 GB SD card is 4 GB. A warning appears if you set a file size
limit that is bigger than a quarter of the SD card capacity.
l
If you set the file size limit and then swap in a smaller SD card, you must change the file size limit to a
smaller size using the Admin panel if the file size limit is bigger than the SD card.
