PAL: Phase Alternating Line, or PAL, is a process for color
transmission for analog TV that is primarily used in Europe, but also in
Australia, South America, and many African and Asian countries.
• The image repetition rate for PAL is 25 Hz.
NTSC: NTSC stands for "National Television Systems Committee".
This is a US institution that defined the first color carrier system for
TV which is now used in most of America and some East Asian
countries.
• The image repetition rate for NTSC is 29.97 Hz.
• 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
Sound Cleaning Lab.
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.
