Estimate movement: These parameters are controlled via the quality controller
(see General Settings).

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 -1/-2, PCM (WAV), or Dolby Digital. You can
also 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. If audio type
"Dolby Digital" is used, then "5.1 Surround" mode may also be selected.
Dual channel enables encoding of two mono tracks (e.g. different language
sound tracks) that can be switched during playback.
Joint stereo is an optimized stereo encoder which takes advantage of the fact
that the signal of both stereo channels is largely identical. Use joint stereo if
you can only use small audio bit rates, but still require a stereo signal.
