11 Nero Digital expert settings
You can define additional settings for the Nero Digital Options in the Burn Settings
screen.
You should only change the expert settings if you are sufficiently familiar with the area of
video encoding, in particular MPEG-4 encoding.
Incorrect settings can have a major negative impact on the quality of the output file
11.1 MPEG-4 terminology
To clarify the options available in expert mode, a number of terms are defined in greater
detail below:
AVC
Advanced Video Coding. Complies with H264 standard. See
H264.
ASP
Advanced Simple Profile. Complies with H263 standard. See
H263.
B-Frame
Bidirectional coded frame..
Only uses the difference information relative to previous and
subsequent key frames (I frames). Because only the
difference information is used, rather the full frame
information, compression is greater.
B-VOP
Bidirectional coded Video Object Plane (see B-Frame). VOP
is only referred to in the context of coding in the H263
standard.
CABAC
Context Adaptive Binary Arithmetic Coding. The name of a
process for arithmetically coding digital video data as part of
coding standard
MPEG-4 AVC and H.264.
Data compression
Process in which data is compressed so that it needs less
storage space and shorter transmission times in data
networks.
EPZS
Enhanced Predictive Zonal Search. An algorithm for finding
motion in video sequences.
GOP
Group Of Pictures. The interval from one I-Frame to the next.
H264
ITU standard for video decoding and compression.
H263
Video compression standard which uses a similar approach
to MPEG-2, but is much more efficient.
I-Frame
Intra coded Frame. Contains the complete integral
information for a particular frame.
I-VOP
Intra coded Video Object Plane. See I-Frame. VOP is only
referred to in the context of coding in the H263 standard.
Interlace
Horizontal skip process. Used when recording, processing
and displaying images. Mainly used for displaying television
signals on receivers based on the CRT principle.
ISO
International Organization for Standardization.
ITU
International Telecommunication Union.
Keyframe
See I-Frame.
