Select the video resolution to use for recording from the list. The frame rate is
limited to 25 frames per second. For the best quality, we recommend using the
default video resolution, 1080p.
You can lower the video resolution during a recording if the media player or
device used to view recordings does not support all video resolutions.
When you change the resolution, the system automatically selects the optimal
bitrate for this resolution.
Select the recording bitrate to determine the file size of the recording. To use
less space on your USB storage device for recordings, select a lower bitrate.
For the best results, use the default value for your chosen resolution.
Bitrate measures the speed of data flow, measured in kbps. 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.
To estimate the space you need for the recording, see
