Setting Up the H.264 Video Encoding Parameters

To Set Up the H.264 Video Encoding Parameters
Proceed as follows to set up the H.264 Video Encoding Parameters:
1. From the user interface of the D9054 HD Encoder, click the Video tab, expand
the H.264 icon and click the Parameters icon from the sub-pages.
2. Set the Loop Filter. This enables (Yes) or disables (No) the de-blocking filter that
reduces the appearance of blocking artifacts, especially at low bit rates. The
default is Yes.
3. Select the Weighted Prediction. This enables the use of the weighted prediction
tool set as specified in the H.264/MPEG part 10 specification. Selections are:
None or Implicit. The default is None.
4. Select the Interlaced Coding Mode.
This selects the Adaptive Frame Field coding mode of the H.264 tool set. The
default is MBAFF only. This is applicable to 1080i mode only. Selections are:
MBAFF only, Picture AFF and Field Picture Only. The default is MBAFF only.
• MBAFF Only - this combines the two fields and compresses them as a single
frame, but before coding the frame, splits the pairs of two vertically adjacent
macroblocks into either pairs or two field or frame macroblocks.
• Picture AFF - this combines the two fields and codes them as one frame
(frame mode). This mode provides the best video quality.
• Field Picture Only - this does not combine the two fields and codes them as
separate fields (field mode).
5. Click Apply.
