The minimum bit rate is derived from the above two values
using the following formula: Minimum = (2 x Average) –
Maximum.

Motion Estimation: Choose the method used to search for
pixel movement in the video stream. This setting has a large
impact on the final quality, and on the processing time as well.
Better motion estimation takes longer to process.

Half-PEL: Choose whether the motion estimation operation
also looks for pixels that move only one half of a pixel from one
frame to the next. This setting should usually be enabled and
should only be disabled if speed is desired over quality.

Reencoding: Choose Always to re-encode all source video.
Choose Never to not re-encode any source video. Choose
Automatic to only re-encode non-standard source video.

Field Dominance: This setting should match the field order of
the source video. DV is generally bottom field first, but other
types of video may be different. In most cases, Toast is able to
detect the field order of the source video and the Automatic
setting should work fine.

Aspect Ratio: This setting should match the aspect ratio of the
source video. In most cases, Toast is able to detect the aspect
ratio of the source video and the Automatic setting should work
fine.

f you selected Custom, choose the audio encoding options:

Audio Format: Choose Dolby Digital or uncompressed PCM. In
almost all cases, Dolby Digital is the best choice. It uses less disc
space, so you can fit more video on the DVD, and the sound
quality is almost the same as PCM.

Data Rate: Choose the bit rate to encode the Dolby Digital
audio. Higher bit rates can produce slightly better sounding
audio, but use more disc space. Toast uses 192 kbps by default.

Dynamic Range Compression: Enabling dynamic range
compression reduces the range between loud and soft sounds
in order to make dialogue more audible, especially when
listening at low volume levels.
