Pearl Nano User Guide Configure recording settings, file size and type
Configure recording settings, file size and
type
Recordings are saved as MP4 files by default. Each channel and recorder also has a file size limit set to 500
MB and the maximum file length set to 30 minutes by default.
When a recording reaches the file length of 30 minutes or 500 MB (whichever comes first), the system
closes the current recording file and immediately opens a new one. No recorded data is lost.
Tip : If you don’t know what size to select, do some test recordings to get an idea of the
file sizes you can expect. If you want to guarantee the recording lasts to a given time
limit, select a file size that is far larger than you saw in your tests.
Important considerations
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 16 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.
l
Recording with a file size limit that exceeds the size of the SD card will corrupt the SD card.
l
Newer recordings overwrite oldest recordings when the amount of free space on the SD card is less
than the configured recording file size limit.
l
You cannot change the recording settings, file size, and type for channels used with Kaltura events.
l
The file recording type for a channel you are controlling and recording using Epiphan Cloud must
be set to MP4 and the maximum file size supported is 500 MB.
