Measurements
These patterns are generally designed for quantitative analysis with a waveform
monitor. Some
of
the patterns can be used with the naked eye to
do
rough qualitative
analysis, especially once you have seen the pattern
on
a variety
of
displays
and
know
what the pattern should look like
on
a properly calibrated display.
Video
Processing
These patterns are primarily designed for evaluating handling
of
motion
and
motion
processing, including
how
well the player
or
display converts interlaced
content
to progressive (also called deinterlacing).
24p
These patterns are all encoded at 24p. They should play smoothly
and
without
artifacts
on
any display
that
has a
24p
mode.
If
you see
judder
(staccato movement
rather
than
smooth)
or
anything other
than
smooth
motion, you should check
to see
if
your player
is
set to produce
24p
output
and
if
your display
is
set
up
to
handle it.
Source Adaptive
These patterns are designed to test the conversion
of
interlaced
content
to
progressive
content
(or "deinterlacing"). Most
of
the sequences in this section
were derived from progressive sources,
and
the very best deinterlacing will use
"film mode" deinteracing, where it restores the original progressive frames.
When
everything
is
working properly, the wedges should look identical to the wedges in
the
24p
test patterns. There should
not
be extra moire, blurriness,
or
other visible
artifacts.
If
the deinterlacer
cannot
reconstruct the original progressive frames,
it
switches to "video
mode",
where it interpolates frames from a single field. This cuts
the vertical resolution in half,
and
in video
mode
the wedges will
turn
blurrier
with
very visible
moire
and
jaggies.
The
"Difficult Edits"
and
"Very
Difficult
Edits"
sequences test the ability
of
the
deinterlacer to handle breaks in the
2•3•2•3
sequence
of
fields
that
are characteristic
