Video as MPEG-4 video
Hint: In order to use the MPEG-4 video export feature, you will have to activate
this function first (view page 331).
MPEG-4 is the most advanced video format available at the moment. Unlike
others, it can provide high-quality pictures at the same file size.
Behind MPEG-4, you'll find a highly complex "academic" standard that
operates and is supported variably according to make. To go into detail on
these differences and parameters would be beyond the scope of this
documentation. For this reason, indications, along with the operational manual
of your device, are given that should help create executable MPEG-4 files. For
more experimental users, the complete setup options of the MPEG-4 codec
can be found behind the "Advanced settings..." buttons.
Video/Audio: The MPEG-4 format and the advanced AVC format are also
available but have, as of yet, only been used in a few devices. MPEG4 video
can be combined with AAC or AMR sound, the latter mostly in conjunction with
mobile phones. The combination ACC/AAC doesn't appear very often (Apple
iPod Video), ACC with AMR in contrast, not at all.
Multiplexer: Here you can find the so-called container formats and special
options for Apple iPod and Sony PSP. MPEG-4 is usually used as an output
format, mobile phones mostly use 3GPP.
Keyboard shortcut: Ctrl + Alt + G
Activate CUDA and OpenCL support
Similar to Burning (view page 255), you can also use OpenCL or CUDA to
accelerate th
e rendering process for MPEG-4/H.264 during export. If you own
an OpenCL or CUDA enabled graphics card, you will find the option to activate
it under advanced settings in the MPEG 4 export dialog. Simply click on
"Advanced...".
Under "Video codec" set whether CUDA or OpenCL should be used.
Note: To import and export AVC(HD) and MPEG-4 files, the MEPG-4 codec
must first be activated (view page 331). A dialog will open if the codec is
required.
