Noise
Filtering
also
increases
the
amount
of
footage
that
can
be
stored
on
a
given
SDHC
card,
because,
by
eliminated
random
spots
of
color,
it
makes
it
possible
to
achieve
a
high
level
of
compression
without
reducing
video
quality.
Sharpener
The
Sharpener
enhances
clarity
by
selectively
increasing
contrast
along
the
edges
of
objects
in
the
frame.
The
Sharpener
is
either
on
or
off.
The
default
is
ON.
Sharpening
is
most
appropriate
in
lighting
conditions
that
create
a
flat
look
to
the
frame
because
of
lower
than
normal
contrast.
Gray
overcast
skies,
deep
shade,
or
indoors
with
indirect
lighting
can
create
this
kind
of
situation.
Sharpening
does
not
affect
video
compression,
so
the
video
file
size
will
be
roughly
the
same
with
sharpening
turned
on
or
turned
off.
Sharpening
should
be
turned
off
if
you
intend
to
edit
the
video
on
a
computer
after
shooting
because
the
adjustments
made
to
the
images
by
the
sharpening
process
may
interact
poorly
with
other
effects
applied
in
later
editing.
Image Quality
When
captured
video
is
saved
to
the
SDHC
card,
the
video
data
is
compressed
in
order
to
significantly
reduce
the
required
amount
of
space
on
the
card.
The
more
that
digital
video
is
compressed
the
more
likely
it
is
that
on
playback
a
viewer
may
notice
some
loss
of
fine
detail,
general
sharpness,
or
other
effects.
Whether
or
not
higher
compression
produces
any
noticeable
effects
depends
upon
on
number
of
factors:
what
is
being
shot,
lighting
conditions,
rapidity
of
movement,
and
other
things.
In
addition,
compression
effects
are
much
less
likely
to
be
noticed
if
the
video
is
played
back
in
a
smaller
format.
If
you
play
back
your
video
in
a
window
on
a
personal
computer
or
downsize
it
for
uploading
to
YouTube
or
some
other
sharing
site,
higher
compression
is
much
less
of
a
consideration
than
if
your
target
is
play
back
on
a
large,
full
resolution
HD
television
screen.
Higher
compression
is
really
only
a
consideration
if
you
are
shooting
video
that
may
overrun
the
capacity
of
your
SDHC
card.
The
best
way
to
determine
what
is
for
you
the
best
tradeoff
between
file
sizes
and
picture
quality
is
to
try
it
and
see.
Record
some
video
at
the
default
High
setting
and
then
some
similar
video
using
Medium.
This
testing
will
give
the
most
reliable
results
if
you
do
it
under
conditions
that
are
like
the
conditions
where
you
do
most
of
your
shooting.
The
Very
High
setting
is
intended
primarily
for
use
by
video
professionals.
Most
personal
computers
may
have
difficulty
playing
back
16
Mbits/sec
video.
For
most
ordinary
uses,
12
Mbits/sec
will
provide
excellent
HD
video
has
a
lower
chance
of
creating
playback
difficulties.
