8.4.3 MPEG-2 Parameters
The following parameters are available for MPEG-2 configuration:
Figure 8.25 – MPEG-2 configuration
Intra DC Precision
Quantization resolution of the DC (luminance) component in intra
frames. Normal setting is 8 bits. Consider to increase precision when
encoding at high bitrates
Video Buffer
Verifier Max Delay
This sets the size of the VBV buffer. The value should be left at
the default (728ms). Reducing the VBV buffer is a technique often
used to lower the video delay, but it can seriously compromise
video quality by forcing excessive quantisation to accommodate I-
frames. This can cause poor references, poor video and I-frame
pulsing artefacts.
Alternate Scan
Defines how transform coefficients are handled. Two modes are
available ; MPEG-1 or alternate. Alternate provides superior results
with interlaced video and should be the default setting.
8.4.4 H.264 Parameters
The following parameters are available for H.264 configuration:
