Item
Description
Frame rate divider
Relates to the frame rate configured in the Encoder Settings
section.
X-resolution
Variables that enable you to freely set picture resolution instead of
using the resolution presets in the Encoder Settings section.
Y-resolution
Stream type
Transport Stream or Elementary Stream.
Quantization matrix
MPEG Default, Alternative 1, or Alternative 2.
Meta data insertion
mode
For details, see the section on Meta Data Insertion.
Disabled
No meta data added to stream.
Fixed interval
Activates Meta data insertion interval
parameter (below).
Each I-frame
Data block is added after each I-frame. The
interval is determined by the GOP length,
therefore.
Meta data insertion
interval
Activate this parameter by setting Meta data insertion mode
(above) to Fixed interval.
Note on Quantization: Quantization is a lossy compression technique used in image
processing. It is based on the fact that variations in high frequency brightness, for example,
are not easily distinguished by the human eye. A quantization matrix, a combination of
predefined values, is used to reduce the amount of information in the high frequency
components of an image, thereby making the stream more compressible. The values in a
quantization matrix are often chosen such that certain frequencies are kept in the source to
avoid losing image quality.
