Tips
and
guidelines
for
getting
the
most
out
of
your
POV.HD
Over
time
you
will
learn
from
experience
exactly
how
you
want
to
configure
the
POV.HD
settings
for
the
conditions
you
shoot
in.
This
section
will
help
get
you
started
and
answer
some
basic
questions
about
how
to
use
the
settings.
Choosing
a
video
format
The
POV.HD
supports
several
different
recording
formats
which
are
designated
by
industry
standard
labels
such
as
1080p30.
In
this
example,
‘1080’
designates
1080
horizontal
scan
lines
in
the
frame,
‘p’
designates
progressive
scanning
which
means
all
lines
in
the
frame
are
captured
in
each
frame,
and
‘30’
designates
30
frames
per
second.
(You
may
have
noticed
elsewhere
formats
such
as
1080i.
In
such
a
case,
‘i’
designates
interlaced
scanning
in
which
the
odd
numbered
scan
lines
are
captured
in
in
one
frame
and
the
even
numbered
lines
in
the
next.
This
method
uses
less
bandwidth
and
less
file
space,
but
in
some
circumstances
such
as
filming
rapid
motion
the
perceived
picture
may
not
be
as
sharp
as
with
progressive
scanning.
Also
the
frame
rate
is
commonly
left
off
the
label
for
consumer
video
equipment
because
consumer
TV
sets
automatically
adjust
to
the
frame
rate
of
the
incoming
signal.)
Format
Resolutions
In
this
illustration,
the
shape
of
each
example
shows
the
shape
(aspect
ratio)
in
which
each
format
is
displayed.
The
area
of
each
example
is
proportional
to
the
resolution.
The
actual
physical
size
of
any
format
is
determined
by
the
device
on
which
it
is
displayed.
