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
). 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
.
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
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 files re-encodes only those parts of the movie that were changed in the
program (e.g. by video cleaning or effects). Please note: The MPEG files contained in the movie must
have the same format, i.e. the bit rates (variable or constant), audio formats, image resolutions, and
video formats must match.
Quick, GOP-precise copying:
This special Smart Rendering mode enables MPEG material to be transferred without having to encode
it for the target medium, thereby greatly increasing the encoding speed. The video material cannot appear
to have been altered in any way; only hard cuts (without fades) are permitted. These won't be executed
precisely to the frame, but will rather take place at the next GOP borders. For this reason, cuts should be
set somewhat more generously.
To burn DVDs in original 5.1 Surround Sound (Dolby Digital Audio) without having to re-encode, this
option has to be activated.
Allows you to rip the necessary settings from an existing MPEG file. This can be useful if you want to
merge MPEG files together without re-rendering via Smart Rendering.
