Pre-processing is a collective term covering all processing of the video signal done prior to the encoding process.
The purpose of pre-processing is twofold.
Please see the Encoder and Transcoder Parameter Guide for more details on these parameters

ONFIGURATION
The following parameters are available for video configuration. The options available may depend on the module
version.
Encoder Type
Selects compression standard to use.
Available options are: H.264 (MPEG-4 part 10) or MPEG-2 video codec.
Profile
Selects the encoder profile to be used. The profile determines the range of
tools from the codec “toolkit” that the encoder is allowed to utilize when
encoding. The level is set automatically depending on the current
configuration.
MPEG-2: Simple, Main and High.
H264: Constrained Baseline, Main and High.
Coding Mode
H.264: PFAF or Filed
MPEG2: MBAFF or Field
Video Bitrate
Sets output bit-rate in CBR mode.
Rate Control Mode
Video CBR (Constant Bit Rate) or CVBR (Capped Variable Bit Rate).
VBR Max
Sets the bounds of the output bit-rate when the encoder operates in
CVBR.
