Chapter 10 Creating MPEG-2 Output Files 149
5 Choose one of the following settings from the Motion Estimation (ME) pop-up menu:
 Good: The fastest ME setting—sufficient when there is relatively low motion
between frames
 Better: A good general purpose ME setting—provides very good results even in the
presence of complex interlaced motion
 Best: The highest quality setting to handle the most demanding and complex
motion for interlaced sources—somewhat slower than the Better mode
See “Quality Tab” on page 134 for more information.
Step 3: Choose GOP settings
Select a suitable GOP structure and size, and decide whether you want the GOPs to be
open or closed.
1 Click the GOP button in the MPEG-2 Encoder pane to open the GOP tab.
2 Choose a GOP structure from the GOP Structure pop-up menu.
For the majority of MPEG-2 encoding jobs for DVD authoring, choose the IBBP
GOP structure.
3 Choose a GOP size from the GOP Size pop-up menu.
For the majority of MPEG-2 encoding jobs for DVD authoring, choose GOP size 15 for
NTSC and GOP size 12 for PAL and 24P.
The options available in this menu are determined by the GOP structure you choose,
and whether or not the GOP is open or closed.
