Note

CBR Bit Rate and Max Bit Rate options are available only when H.264 codec is
selected.
GOP : 1 ~ 60/ 1 ~ 50
Group of pictures length. Select the GOP length number from 1 to 60 for 60Hz Camera Type or 1 to 50
for 50Hz Camera Type. Smaller number means the distance between 2 I-frames is smaller, which
needs more network bandwidth while having better image quality. By contrast, larger number
consumes less bandwidth but in an unstable network connection, video display may not be smooth.
The available length number options of GOP will vary based on frame rate settings.
Quality Level : VBR/CVBR : 1 ~ 10 ; MJPEG : Low/ Mid/ High
Select the Quality Level number from 1 to 10 for H.264 Codec with VBR or CVBR Rate Control selected,
or Quality Level Low/ Mid/ High for MJPEG Codec. “High” or “larger value” produces the highest image
quality but increases the file size. By contrast, “low” or “smaller value”, produces the lowest image
quality with decreased file size and network bandwidth consumption.
