3xLOGIC VIGIL Client - Manual (Page 35)

Note: Color detection is a CPU intensive setting.
Use B Frame
Uses bi-directional frames to decrease the file size of recorded footage.
Note: This setting is extremely CPU and Memory intensive.
MPEG4 CODEC Settings
To switch the recording CODEC to MPEG4, select the MPEG4 option from the CODEC drop-down menu.
Key-frame Rates
Sets the number of key-frames recorded per second. The higher the value, the greater the data space
needed for recording, but the higher the quality of the video.
Motion Search Scope Changes the size of the regions used to detect motion.
Quantization Method
Selects the type of compression. H263 offers higher compression than MPEG4 but requires more CPU
usage.
ME Accuracy
Motion Estimation Accuracy includes two options: Full Pixel and Half Pixel. Full Pixel checks for
motion comparing differences of full pixels. Half Pixel will check for motion using an interpolation
method that detects finer movements.
Note: Half Pixel is a CPU intensive setting.
ME Algorithm
The Motion Estimation Algorithm changes the shape of the area used for motion detection and includes
two options: Full Search and Fast Search. Fast Search will save CPU time but Full Search is more accu-
rate.
ME Vectors
Sets the number of vectors tested for motion from 1 to 4. The greater the number, the more CPU proc-
essing is required.
Hardware CODEC Settings
Depending on the VIGIL Server model, it may use Hardware CODEC recording, which has slightly different customization options. For
some types of cards the CODEC used can be changed on the VIGIL Server Settings | Hardware Tab via the Hardware CODEC Dropdown
box.
