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 com-
paring 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 accurate.
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.
