MPEG-4 encoder settings (main concept) 355
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
MVC: Multiview Video Coding (MVC) is an expansion for stereoscopic applications.
Activate this to export MVC files.
Note: MVC is only available in the Video deluxe Pro versions.
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 an improved image quality, but
encoding takes place approximately twice as long.
Smart Render and Smart Copy
Smart Render lowers the demand on the encoder for AVCHD material. In the
production of AVCHD files, only those parts of the movie that were changed in the
program (e.g. by video cleaning or effects) are re-encoded. Please note: The AVCHD
files contained in the movie must have the same format, i.e. the bit rates (variable or
constant), audio formats, image resolutions and video formats must match.
The Smart Rendering special mode „Smart Copy“ enables AVCHD material to be
transferred without having to encode it for the target medium which greatly increases
the encoding speed. The video material cannot appear to have been altered in any
way, only hard cuts (without fades) are permitted. These won't be executed precisely
to the frame, but rather take place at the next GOP borders. For this reason, cuts
should be set somewhat more generously.
Hardware acceleration - CUDA, Quick Sync Video, OpenCL
The MPEG-4 encoder from MainConcept supports the use of hardware acceleration
for AVCHD export as well as AVCHD and Blu-ray (H.264) encoding (burning). This
can noticeably speed up the encoding process.
The following hardware acceleration technology is supported:
• Quick Sync Video (Intel)
• OpenCL (AMD)
• CUDA (NVIDIA).
