Rec Mode Conversion Dubbing
_/_/_/_/
Allows you to dnb from the HDD to a DVD or vice
versa, in a dnbbing mode that differs from the
original recordings. For example, when you dub
an HQ title (data size is large) in SP mode, you can
reduce the data size, saving more titles using less
space.
Select a mode different from the original recording
in "Dub Mode" in the steps of "Dubbing a Single
Title (Title Dub)" (page 74) or "Dubbing Multiple
Titles (Dub Selected Titles)" (page 75).
When an HQ or HQ+ title is converted to another
mode, the recorder automatically assigns an
appropriate bit rate, thus retaining the original
picture quality as much as possible ("Dynamic
VBR Dubbing").
4,About "VBR"
VBR (Variable Bit Rate) is an effective method of
allocating a suitable bit amount per second. Fine
detail pictures or dynamically moving pictnres are
assigned a larger amount, while static pictures are
assigned less, for optimum pictnre qnality.
• Variable bit rate (adopted • Fixed bit rate
for this recorder)
Average distribution rate Average distribution rate
Wasted bits More bits
are required
"_" Hint
When you dub an edited title using tile Rec Mode
Conversion Dubbing method pauses between scenes ale
smoothed out.
The picture qualiD, will not improve even ifa title is
convel_ed to a recording mode of better picnue quality
Dubbing restriction
Some DVD VIDEOs or TV programs contain
copy protection signals such as "Copy-Never" or
"Copy-Once." You cannot record such contents on
this recorder (only a gray, blank screen will be
recorded). Be especially careful when dubbing on
a non-rewritable DVD such as a DVD-R.
