MPEG-4 encoder settings
Tip: First, check if there is a suitable preset in the export dialog for your
purposes. Before changes are made in "Advanced settings", the effects and
interplay of the different parameters should be familiar.
The "Advanced settings" are divided into "Video", "Audio", and "Multiplexer".
l to
rted, both of these encoder settings can be selected for compressing the video
material. It is important in this case to know how the material will be played back.
Under "Audio", there is a choice between "
AMR (view page 295)" and "AC (view page
295)". The AMR format is more suitable for mobile devices that don't necessarily require
high playback quality. ACC is more flexible, on the other hand, but it is supported by fewer
mobiel devices.
For material that is not exactly specific, encoder qualities recommend AVC image and AAC
sound, since these encoders are equally suitable for all source material.
The option "Export as website" also creates an HTML page in an integrated Flash player
that can play back the video created. Read the topic "
Embed Flash videos into your own
web site
(view page 266)".
MPEG-4
The MPEG-4 (H.263) codec is especially useful for video material with little or only slower
movements.
Generic

Different presets located within the encoder.
(A)SP@L0-L5: (Advanced) Simple Profile in Level 0-5
(Q)CIF (Common Intermediate Format): CIF is a video format produced as soon as 1990
with the video compression format H.261. At that time, the format was used for video
telephone conferences.
The "Q" in QCIF stands for "Quarter", and since resolution is halved in terms of height and
width compared to CIF, the entire size is only a quarter of CIF.
QCIF was popular with mobile telephone manufacturers, since the resolution of 176 x 144
e for the first affordable SmartPhones (144 x 176).
(Half)D1:
ing that the pixel number of the height and weight is 2/3 of D1.
Behind MPEG-4, you'll find a highly complex "academic" standard that operates and is
supported variably according to make.
Under "
Video", there is a choice between "MPEG-4 (view page 285)" (H.263) and
"AVC/H.264 (view page 290)". Depending on the purpose of application of the materia
