Video Quality and Disc Size
Sonic MyDVD includes four DVD video quality
(bit-rate) settings, and a Fit-to-DVD option that can
be applied to a video project or to individual movie
files. The DVD quality settings are:
■ HQ (High Quality) — Best audio and video
quality, but requires the most disc space per
second of video. Good choice for video files
that contain high-speed action (for example,
motor sports).
■ SP (Standard Play) — Good audio and video
quality with most video sources.
■ LP (Long Play) — Fits approximately twice as
much video onto a DVD as HQ. Not
recommended when the original video is
low-quality or noisy.
■ EP (Extended Play) — Fits the most video onto
a DVD, but video quality is low. Not
recommended unless the original video is very
good quality.
■ Fit-to-DVD — As you add more content to
the project, MyDVD reduces the project
quality automatically to fit the selected disc
size. Fit-to-DVD is the default setting for new
projects.

VCDs have a fixed
bit-rate which
delivers one quality
level. You can fit
approximately one
hour of video on a
VCD (the recording
time is reduced if
you use animated
menu buttons or
