Video settings
Compression: You can choose either MPEG-1 or
MPEG-2 compression. MPEG-2 offers higher
resolution and higher quality than MPEG-1.
Note: MPEG-2 files require special decoder software.
If you do not have an MPEG-2 decoder installed on
your PC you will not be able to play MPEG-2 files.
Width, Height: The frame size is measured in pixels.
Decreasing the dimensions greatly decreases the
amount of data, and therefore the file size, but com-
pression reduces the effect. The maximum resolution
for MPEG-1 is 384 x 288. The maximum resolution for
MPEG-2 video is 720 x 576.
Bit rate: Choose whether to create the MPEG file with
VBR (variable bit rate) or CBR (constant bit rate)
encoding. The VBR option uses less storage at a given
quality level than CBR, but may cause problems when
the file is viewed using some DVD players. If you
observe jerky or stuttering playback, use CBR.
Data rate: You can adjust the data rates for audio and
video separately by using the sliders. Higher data rates
yield higher quality, at the cost of larger files.
