The Advanced MPEG Video Settings provide you with the ability to choose the MPEG Type
required for your output. As set forth in the figure and descriptions of the MPEG Types set forth
below, these include the following:
MPEG-4
MPEG-4 is the basic MP4 compression which can be used for web (streaming media) and
mobile devices. Use this compression setting if you are experiencing compatibility issues
with your playback software or device when using H.263 or H.264.
H.263
MPEG-4, Part 2, or H.263, is designed for situations where low bit rate and low
resolution are mandated by other conditions of the applications, like network bandwidth
or device size. Examples of video applications for H.263 are cell phones, some low end
video conferencing systems, and surveillance systems. H.263 is important for legacy
handheld devices that do not support H.264.
NOTE: By default, Niagara SCX’s H.263 uses Simple Profile unless you select the
“Enable B Frames” option. If B frames are enabled, then the resulting stream will be
Advanced Simple Profile.
H.264
H.264, MPEG-4, Part 10, or AVC (Advanced Video Coding) was designed for very high-
data compression while maintain better quality than its predecessor, H.263. It was also
created to address a broad range of applications from low bit rate to high bit rate and
from low resolution such as cell phones to high resolution such as broadcast.
Niagara SCX’s H.264 is Baseline Profile
3GP – MPEG-4
3GP is a multimedia container format defined by the Third Generation Partnership
Project (3GPP) for use on 3G mobile phones. It stores video streams such as MPEG-4 or
H.264 and audio streams such as AMR or AAC.
There are two defined standards for this format which are:
1) 3GPP for GSM based mobile phones
2) 3GPP2 for CDMA based mobile phones
This setting will create an MPEG-4 stream stored in a 3GPP container.
3GP – H.263
This setting will create an H.263 stream stored in a 3GPP container.
3GP – H.264
This setting will create an H.264 stream stored in a 3GPP container.
3G2 – MPEG-4
This setting will create an MPEG-4 stream stored in a 3G2 container.
