Recording with Pearl Nexus
Pearl Nexus encodes the video and audio it captures. You can stream your content and record it at the same time. You can even stream your switched program using a lower quality stream (i.e. 1280×720 at 2Mbps) and at the same time make a high quality recording of the second channel (i.e. 1920×1080 at 4 Mbps).
There are different ways to download recordings, like automatically downloading recordings to a USB memory device.
About recording
You can record a channel on Pearl Nexus as AVI, MOV, MPEG-TS, MP4, or MP4-Fragmented. Easily stop and start recording using any of the following:
| Epiphan product | Admin panel | Device screen | Epiphan Edge | Epiphan Live |
|---|---|---|---|---|
| Pearl Nexus | Yes | No | Yes | Yes |
If an accidental system shutdown occurs while recording is in progress, your recordings are 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.
Pearl Nexus also come with APIs so you can setup third party tools to control recording.
You can set the maximum recording time or file size limit 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. When the local drive is full, newer recordings overwrite oldest recordings.
Important considerations
If recordings are selected for Automatic File Upload (AFU) while AFU is at maximum upload capacity or when AFU is unavailable, the recordings are added to an upload queue.
If the channel that is recording is an auto channel, a new recording is started if the video input source automatically switches from one video source to another due to signal loss.
You can also set up multi-track recorders on Pearl Nexus.
While actively recording a multiple-channel recorder, a new file is created if an additional video input source is added to the recorder.
