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 comes with APIs so you can set up third party tools to control recording. For information on the current REST API, see: Pearl System REST API Guide. For information on the Legacy APIs, see: Pearl System Legacy RS-232/HTTP API Guide.

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 there is no available space left in the storage medium, new recordings fail and do not overwrite recordings in the AFU queue.
  • For information about recording to Content Management Systems (CMSs) like Kaltura and Panopto, see CMS recording and webcasting control.
  • Pearl Nexus - You can also set up multi-track recorders on Pearl Nexus, see Multitrack Recorders.
  • 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.
