MPEG-4 encoder settings 289
Max. rate
This is the maximum bit rate that should be present in the video stream, i.e. maximum
number of bits that may be
transferred to the decoder.
Note: This option is only available in "Variable bit rate" mode.
VBV buf. size
VBV is the abbreviation for "Video rate buffer verifier definition" and the size of the buffer
(storage area) that is applied to the encoding.
The larger the buffer is, the better the results will be, but the processing will also take much
longer. The smaller the buffer is, the more parallel processing can take place at the same
time in RAM.
Pixel aspect ratio
Specifies the page ratio of the individual image points (pixels).
Meaning: Different television norms and the standard pixel ratio. Select a setting and the
are displayed as "X" and "Y".
X/Y: The actual pixel ratio. If under "Meaning" the setting "Custom" is selected, then a
custom ratio can be set.
GOP structure
Max key interval
Determines the maximum
GOP (view page 303) length. High values mean improved
compression. Lower values create stronger security protection and enable improved
access to individual frames for processing the video.
B-frames count
(view page 305). Several applications, e.g. video conferences,
r this, i.e. no B-Frames, in order to enable the shortest possible
allowing you to
I frame (view page 304) after a scene change.

Scene change detection
If this option is activated the scenes will be detected during encoding, thus
