5 If you selected Custom, choose the video encoding options:
■
Average Bit Rate: Sets the desired average target bit rate for the
video encoder.
■
Maximum Bit Rate: Sets the maximum bit rate for the video
encoder.
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, but 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 reencode all source video.
Choose Never to not reencode any source video. Choose
Automatic to only reencode 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.
