Preview DVD-specific options
Stream Settings
Format
Specifies the file format of the target DVD.
Video-Basic
Frame Size
Specifies the frame size of the target DVD.
Quality/Speed
The Quality/Speed setting determines the quality vs speed trade-off the encoder uses.
High Speed Optimize encoding for the highest speed.
High Quality Balance encoding speed versus quality.
Highest Quality Optimize encoding for the highest quality.
Mastering Quality Perform all encoding optimizations to produce the absolute
best quality at the specified bitrate setting without regard to
encoding speed. This option should not be used for performance
benchmarking as it is an exhaustive process that can take 10-20
times longer than the other modes.
Max GOP size
Sets the maximum GOP (Group Of Pictures) size. Larger GOPs provide better
compression while smaller GOPs provide faster access.
GOP Structure
Specifies the maximum distance between I and P frames, which determines the GOP
(Group Of Pictures) structure.
Automatic Sets the GOP structure automatically based on the content.
I-Frame only Creates output without P and B frames.
1 frame (IPPP ...) Creates output with a maximum of 1 frame from I to P frames.
2 frames (IBPBPBP...) Creates output with a maximum of 2 frames from I to P frames.
3 frames (IBBPBBP...) Creates output with a maximum of 3 frames from I to P frames. This
is the standard for DVDcompliant MPEG streams.
