Advanced video settings
MPEG profile and level: The MPEG-2 standard defines so-called "profiles" and "levels". For creating
SVCDs and DVDs you can use "Main profile and Main level". The high profile adds additional
properties to the data stream like the option to display an image at a reduced resolution for restricted
transmission quality (SNR-scalable profile), or locally scaled, for instance an HDTV
data stream on a standard TV set. The 4:2:2 profile is used if the image data is to be encoded for
alternative chroma scanning. However, these profiles are supported by very few encoders, and mainly
only for professional use.
These levels define the restrictions to the image resolution and the maximum data rate. Low level can only
reach a reduced resolution (352x2888 = CIF); high level, or High 1440, enables encoding in HDTV
format.
Estimate movement: These parameters are controlled via the quality controller (see General Settings).
Other
Noise sensitivity:
This factor defines how sensitive the encoder will react to noise in the source material. If the source
material only contains a little noise (digital recordings, computer animations, or material already de-noised
by video cleaning), then you don't have to change the default value 4, or you can even reduce to increase
the quality further. However, if you want to encode noisy material, then too low of a factor will
considerably increase the encoding time at the cost of quality. For an unedited analog video you can
increase the factor to 8-14.
Noise reduction
(click on noise sensitivity): A noise filter is used with adjustable settings from 1-31.
Advanced parameters
Additional expert settings are available in the tree to the right of the window. These should only be
changed by experienced users. They have been optimized for general applications to such an extent that
changes are only necessary in exceptional cases.
Audio settings
Audio type: You can use MPEG Layer 1, 2 or PCM (WAV
) audio. Select "No audio" in the export dialog.
Sample rate:
You can set a sample rate of 32, 44.1 or 48 kHz for the audio track. VCDs and SVCDs require 44.1
kHz, DVDs require 48 kHz. To reduce the size of audio data it is recommended to lower the bit rate
instead of the sample rate.
Mode:
You can use Mono, Stereo, Joint Stereo or Dual Channel.
Bit rate:
Here you can set the bitrate of the audio signal. The higher the bit rate, the better the playback quality.
VCD requires 224 kBit/s, and for SVCDs and DVDs select a value between 384 kBit/s and 448 kBit/s.
