z Quality Value: When variable bit rate is selected as the rate control mode and
customized mode in Compression Ratio, the quality value can be selected
between 1 and 31.
– Low: default is 31
– Mid-low: default is 24
– Standard: default is 16
– Mid-high: default is 9
– High: default is 1
H.264- The following settings are enabled when "Image Mode" is set to H.264
z Resolution
Configure the resolution. The higher the resolution the larger the image file.
Possible settings: SVGA, VGA, QVGA (when PC/VGA Resolution is selected)
D1, 2CIF, CIF, QCIF, 4CIF (when Video Resolution is selected).
z Frame rate: 7 frame rates can be selected (1, 2, 3, 5, 10, 12, 25)
z Rate control mode: you can choose between variable bit rate and constant bit
rate.
z Compression Ratio
Set the quality of the delivered images. The size of the image files (H.264 files)
depends on the compression ratio.
– Quality value default: 31
– Mid-low: 24
– Standard: 16
– Mid-high: 9
– High: This setting produces lowest image quality. The file size decreases.
Quality value is set to 1.
z Compression Ratio
Set the quality of the delivered images. The size of the image files (H.264 files)
depends on the compression ratio.
– Low compression: This setting produces the highest image quality. The file
size increases.
– Mid compression: Standard setting.
– High compression: This setting produces the lowest image quality. The file
size decreases. Only aktiv at “variable bitrate”.
z Quality Value: When variable bit rate is selected as the rate control mode and
customized mode in Compression Ratio, the quality value can be selected
between 1 and 31.
– When picture resolution is ≥ 720p, the file size could be more than 4 MB.
z GOP: default is 25 (1 I frame plus 24 P frames). GOP can be selected between
1 and 64.
– 25fps:GOP 1~64
– 12fps: GOP 1~36
– 10fps: GOP 1~30
– 5fps: GOP 1~15
– 3fps: GOP 1~9
– 2fps: GOP 1~6
– 1fps: GOP 1~3
z Profile: You can choose between Baseline, Main profile and High profile.
JPEG - The following settings are enabled when "Image Mode" is set to "JPEG".
