Appendix: MPEG Encoder Settings
General settings
MPEG type: Set the output type of the created MPEG file. You can
adjust the encoder settings freely (to export your video in the
corresponding format, for instance) for further use in other programs
or on your own website.
If you open the encoder from a burn dialog, or intend to use the
exported material for VCDs, SVCDs or DVDs, then select the
corresponding option. This will adjust the settings of the encoder
according to the standards required for the corresponding discs to
be played in a compatible player.
Video format: Automatically specifies the video format, aspect ratio,
and frame rate (see video settings (view page 123)). You can choose
between PAL or NTSC.
Interlace mode: The movie is encoded interlaced (i.e. in two
half-screens, so-called fields). This is essential for later playback on
TV screens. If you want to view the exported movie on your PC only
and like a "cinemascope" view, you can also encode by frame
(progressively). Some video projectors also support playback of
progressively encoded image material. See Interlace (view page 131).
Bit rate: The bit rate determines the memory requirement by the
completed video. The amount of data available can be used
differently for different display modes. 20 MB can be 4 seconds of
DVD video, or 5 minutes of Internet streaming at the thumbnail size.
The quality of an MPEG video is measured by the width of the
created data stream, i.e. the bit rate. This is the amount of
transmitted data per time unit and is indicated in kBit/s or bit per
second.
Quality: Determines the quality of the encoding process, or the
quality of the movement (view page 128) to be more precise. The
higher the quality, the better the finished video will look, but encoding
will take considerably longer. The preset value "10" is a good
compromise between speed and quality.
Smart Rendering: Smart Rendering can considerably reduce the
encoding/processing strain of MPEG files. The production of MPEG
