WM Configuration

JPEG Configuration

The following fields enable image capture and specify the capture interval and compression quality. Note that if you change any of these parameters for a live encoder stream, there will be a momentary (10 seconds or less) loss of video. (For JPEG capture status, see Status:

JPEG Status on page 100.)

Image Capture Enable

Check this box to enable image capture. Default = disabled.

 

Note that toggling this parameter on or off will reboot the

 

appliance.

 

 

Image Capture Interval

1–600 seconds. Specify the interval at which images are

 

captured. Default = 5.

 

 

JPEG Compression Quality

0–100. Values over 80 marginally affect image quality and

 

may impact other system resources. For best results,

 

experiment with the output and choose the lowest value that

 

provides acceptable image quality. Default = 80.

 

 

Deinterlaced Image Enable

Vertical resolutions above 288 lines are deinterlaced to

 

provide higher vertical resolutions. Deinterlacing while there

 

is motion on the encoded video can cause visual artifacts on

 

the captured JPEG image. Be aware that disabling interlacing

 

removes the visual artifacts but creates a JPEG image that is one

 

half the height and one half the width of the original resolution. For

 

example, a 640x480 video resolution will be encoded as a

 

320x240 JPEG file. Default = Disabled. Note that toggling

 

this parameter on or off will reboot the appliance.
