 SECAM: SECAM is a TV norm in France and eastern Europe for transferring
analog color video signal.
 MAC: The MAC process (Multiplexed Analogue Components) involves TV
norms developed for satellite TV. They have also been developed for an HDTV
standard (HD-MAC).
 Unspecified: This setting does not make any special optimization.
Tip: The best results are achieved with the setting "Auto", since this
automatically uses the project settings as a basis by MAGIX Video Pro X4.
Profiles
Defines which profile is applied in the AVC/H.264 stream.
 Baseline profile: The basis of applications with limited computing
performance, especially for video conferences or videos on mobile telephones.
 Main profile: This profile was originally intended for the broadcast industry and
for backup purposes. The process has however retreated somewhat from use,
since "High Profile" has been developed for these purposes.
 High profile: This profile is used for broadcast and backup applications, and it
is also used sometimes in the HDTV industry (High Definition Television). For
example, this profile for HD-DVD and Blu-ray Discs.
Level
H.264 defines different levels. The higher the level, the larger the video's bit
rate. In this table, you can see the maximum permitted values for the
respective level in relation to the selected profile.
