Scene change detection
If this option is activated the scenes will be detected during encoding, thus
allowing you to insert an I frame (view page 395) after a scene change.

MPEG-4 H.264
The MPEG-4 H.264/AVC codec is suitable for all types of material; however, it
requires relatively higher CPU power for later decoding.
In the advanced encoder settings of the AVC encoder the "Generic" options in
"Main Settings" are mainly interesting.
The AVC preset and video format can be adjusted here. For instance, if DVD
quality is desired you should select "DVD". The video format should be
selected specific to the country so that the material can be played on the
devices most commonly available in these countries. For instance, you should
select PAL for Germany, SECAM for France and NTSC for the US.
MVC: Multiview Video Coding (MVC) is an addition for stereoscopic
applications. Activate it in order to export MVC files.
2-pass: The video to be exported will be encoded twice. The first run-through
serves to calculate the streaming rate for each section (for video this is per
frame). The second run-through is when the actual video is created with the
streaming rates that were calculated in the first run-through. The result is
improved image quality, but with nearly doubled encoding times.
Smart Render: Smart Rendering significantly reduces encoding times for
AVCHD files. When creating AVCHD files, only those portions of the movie are
encoded anew which were changed in the program (e. g. with video cleaning
or effects). The AVCHD files in the movie must have the same format, meaning
bit rate (variable or constant), image resolution and format must match.
