On the Encoder properties page the compression parameters are defined.

Compression
Number of Inter Frames Indicator for the number of inter frames between two intra frames
inter frame: characterizing the difference between two consecutive frames;
intra frame: complete autonomous frame

ORM
SCN reduces automatically the interval for intra frames, if fast changing
image contents are observed and additional bandwidth reduction can be achieved
this way.
The default value -1 corresponds to 100 inter frames.
Noise Threshold Noise threshold defines how much the value of adjacent pixels within a color
plane might differ without being regarded as a change in color value.
Auto stands for auto-selection of the best parameter with respect to noise and
optimal compression
Lossless stands for lossless transfer of the images.
Values from 1 up to 16 are possible, where 16 stands for optimal compression but
may cause trails for moving objects.
