3. Change the settings as desired. See “Choosing bit rates for video and audio” on page 67
for help:
- Encode Set: DVDit Pro HD comes with several sets of predefined transcoder
settings. You can choose a predefined set or change the Video and Audio settings
yourself.
Video settings:
- Encode Style: To fit a lot of video on the disc without losing too much quality,
choose VBR (variable bit rate). CBR (constant bit rate) is suitable only for shorter
durations.
- Min, Target, and Max Bit Rate: These set the quality level for all non-compliant
video (including motion menus).
Audio settings:
- Type: For Blu-ray output where disc space is less of an issue, you should choose
PCM to obtain the highest quality audio. You may want to select Dolby Digital if
you are outputting high bit rate video with multiple audio tracks, or if you need
additional space on your Blu-ray disc for video.
- Bit Rate: The normal Dolby stereo bit rate is 192 kbps; you can choose higher or
lower rates depending on the desired sound quality. The PCM audio bit rate cannot
be changed.
Menus/Slideshows:
- Size: Determines the size and resolution of motion menus and slideshows when
they are composited for output.
- Frame Rate: Determines the frame rate for motion menus and slideshows when
they are composited for output.
4. Select the “Convert All Compliant Video and Audio Files” option only if you need to
re-encode Blu-ray-compliant files as well as non-compliant files.

DVDit Pro HD does not re-encode multi-channel Dolby Digital audio, even if you select the
