Field Description
Resolution Select the video resolution to use when recording meetings to a local USB storage
device. The frame rate is limited to 25fps. For best quality, use the default 1080p
resolution, but use a lower value if your media player does not support higher
resolutions.
When you change the resolution, the system automatically selects the optimal bitrate
for this resolution.
You cannot change the video resolution for meetings recorded to the network. If you
selected Automatic as the Location, this resolution is applied only when recording to
the USB device.
Bit rate Select the bitrate to determine the file size when recording meetings to a local USB
storage device. To use less disk space, select a lower bitrate. For the best results, use
the default value for your chosen resolution.
Bitrate is the speed of data flow. Higher video resolutions require higher bitrates to
ensure the video is constantly updated, thereby maintaining smooth motion. If you
lower the bitrate, you lower the quality of the video. In some cases, you can select a
lower bitrate without noticing a significant drop in video quality; for example during a
presentation or when a lecturer is speaking and there is very little motion. In video
recordings, the bitrate determines the file size for each minute of recording. Bitrate is
often measured in kilobits per second (kbps).
To estimate the space you need for the recording, see Table 10: Typical file sizes
based on the bitrate on page 81. You can see how much recording time is available
on your target disk when you access the Recording menu (see Recording
Meetings on page 67).
You cannot change the bitrate for meetings recorded to the network. If you selected
Automatic as the Location, this bitrate is applied only when recording to the USB
device.
Audio Alert When recording meetings to a local USB storage device, you can indicate to all
participants that the meeting is being recorded. Select Yes to enable an audio
message alert at the beginning of the videoconference. This alert is also sent to late
participants.
When recording meetings to the network, an alert is always sent to participants.
Ignore Mute on
Playback
Select Yes to play audio when viewing a recording, even if the volume on the endpoint
is muted. For more information about the sound settings, see Adjusting the Default
Volume Settings on page 52. For privacy, you can connect headphones as described
in Connecting Headphones to the Scopia
