Defines how transform coefficients are handled. Three modes are
available; ON, OFF and Auto
8.5.6 H.264 Parameters
The following parameters are available for H.264 configuration:

Universal Transcoder- dense broadcast H264g parameters
Reference B-Frames
Enables B frames to be referenced to I, P or B frames. When
disabled, B and P frames can only reference I or P frames.
8x8 transform
Available in high profile mode only. This enables 8x8 transform
for residual coding. This can provide significant advantages for
HD encoding.
CABAC
CABAC (Context Adaptive Binary Arithmetic Coding) is an
entropy coding scheme introduced in H264. When enabled,
CABAC is used instead of CAVLC. CABAC is the most efficient
of the two, and should be the default choice. Some legacy
decoders might not support CABAC.
IDR Frequency
Sets how often I frames shall be converted to IDR
(Instantaneous Decoder Refresh) frames. IDR points are intra
frames without past references. The IDR frequency can be
important for decoders offering fast trick play (fast forward /
rewind).
8.5.7 Audio Parameters
The following parameters are available for Audio configuration:
