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
i
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

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 304).
Bit rate: The bit rate determines the memory requirement by the completed video. 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

mart Rendering: Smart Rendering can considerably reduce the encoding/processing
train of MPEG files. The production of MPEG files re-encodes only those parts of the
ovie that were changed in the program (e.g. by video cleaning or effects). Please note:

must have the same format, i.e. the bit rates
