If you have an HDTV and a Blu-ray player, this calibration disc can help you make sure you're getting the best-looking picture possible. Whether you own a flat-panel TV, a rear-projection set, or a front projector, this disc can help you maximize your investment. It includes a comprehensive set of test patterns for color, contrast, sharpness, and lots more.
Previous calibration discs have tended to be either too basic, or so complicated that you needed to be a video engineer to use them. With the Spears & Munsil disc, you can make as few or as many adjustments as you want. Each test is clearly explained, with examples of correct and incorrect settings, so you know what you're doing and why. Running through the entire set of tests usually takes 45 minutes to an hour.
"The Spears & Munsil disc is the most effective calibration disc I've used. I'm particular about picture quality, and didn't expect a dramatic improvement, but after using the disc, my TV's picture definitely looked more natural."

Overview: The Spears & Munsil High-Definition Bench Mark
Hand Forged Video Disc is a Blu-ray video test and evaluation disc to help
you get the most out of your HDTV and Blu-ray player. All
test patterns and clips are created at 1080p in native color space using custom software.
Note: Can only be played on a Blu-ray player. Not compatible with
other disc players.
Setup & Evaluation Patterns: The Blu-ray video test
disc provides Calibration and Evaluation Patterns for all major display
controls to measure your HDTV's and Blu-ray player's quality.
- PLUGE: PLUGE stands for Picture Line-Up Generator.
- PLUGE Low: This pattern is used to set the black level
of the display by adjusting the brightness control.
- PLUGE High: This is a pattern used to check that the black
level looks correct even when there is another bright image on the
- Contrast: This pattern is designed for fine-tuning the settings
of the brightness and contrast controls. All of the numbered white bars
should be visible and distinct from the surround background.
- Sharpness: This pattern is used to check for sharpening artifacts
such as ripples near hard edges. The vertical and horizontal lines should
have clean, sharp edges with no ghost lines or bright halos next to them.
The circles and diagonal lines should be smooth and free of stair-stepping.
- Color Bars:
- SD Color Bars: This pattern is designed for setting the color
(sometimes called "picture") control on the display. This requires a
blue filter or the ability to turn off the red and green channels on the
- HD Color Bars: This is an alternate color bar pattern
designed for modern displays. To set color, look through a blue filter,
or put the display in "blue-only" mode if available, and adjust the
blue, cyan, and magenta bars so they match the brightness of the white
bar beneath them.
- Clipping: This pattern is designed to show clipping of the peaks
in both the luma channel and the three RGB display channels. Each patter
has concentric squares that range from the reference level to the peak level
for luma (white) and the four color channels. A properly adjusted display
should be able to reproduce all of the levels.
- Image Cropping: This pattern is designed to show how much of the
image encoded on the disc is visible on the screen. It can also be used to
center the picture on screen.
- Chroma Alignment: This pattern is designed to test alignment
of color channels. The colored lines should be exactly centered in the
thin diamond shapes. If the colored lines are shifted to the left or
right, then the chroma channels are misaligned with the luma channels.
Every element of this pattern should look symmetrical, with the right
side matching the left side and the top matching the bottom.
- Chroma Multiburst: This pattern is designed to test the
bandwidth of the chroma channels. All of the burst patterns should show
clear blue and red stripes, with the peaks at essentially the same
intensity as the stripes on the far left.
- Chroma Zone Plate: This pattern is designed to check overall
chroma resolution and reproduction. The center o the pattern should be
clear, bright, and smooth. No stair-stepping should appear on the edges
of the concentric circles. The brightest peaks should look rounded and
not flat or clipped.
- Chroma Upsampling Error: This pattern checks whether the
MPE-2, VC-1, or AVC decoder in your player is properly upconverting the
chroma channels for progressive 4:2:0 content. The diagonal lines should
be smooth and free of obvious jaggies, steps, or streaks.
- Luma Multiburst: This pattern is designed to test the
bandwidth of the luma channel. All of the burst patterns should be
clear, with the peaks at essentially the same intensity as the stripes
on the far left.
- Luma Zone Plate: This pattern is designed to check overall
luma resolution and reproduction. The center of the pattern should be
clear, bright, and smooth. The center of the pattern should be clear,
bright, and smooth. No stair-stepping should appear on the edges of the
- Dynamic Range:
- Dynamic Range High: This pattern is designed to show whether
the display is reproducing all the levels above reference white up to
peak white. On a properly adjusted display, all the bars except the
brightest one should be visible and distinct from the background.
- Dynamic Range Low: This pattern allows you to check if all of
the range possible in the video signal is being sent to the display.
Under normal circumstance, only bars 18 and above should be clearly
visible, and possibly just barely bar 17.
- 11 Step Crossed Gray Scale: There are 11 levels of black and
white on this chart, and all 11 levels should be clearly visible. The far
left and right bars are slightly wider; this is normal.
- Geometry: This pattern is designed to facilitate measuring
whether the display is distorting the height or width of the picture.
Using a tape measure, measure the height and width of the circles and
squares. They should be equal. The diagonal sin the center should also
be equal length.
- Geometry 4x3/16x9 PIP: These patterns check whether the
player is rendering Picture-in-Picture (PIP) with the correct aspect
ratio. The circles and squares in the PIP frame should not be distorted.
The diagonal lines of the main frame and the PIP frame should be aligned
Source Adaptive Deinterlacing Clips: The Blu-ray test disc also
provides Source Adaptive Deinterlacing Clips and patterns to test your HDTV's
and Blu-ray player's overall deinterlacing performance.
- Wedge Pattern: As the wedges move, the narrow end of the
horizontal wedge should have clear alternating black and white lines rather
than blurry or flickering lines. The overall brightness of the wedge should
be the same across the entire length. Both wedges should remain steady and
not flicker for the length of the clip.
- Racecar Clip: As the car moves across the screen, the bleachers
in the background should be detailed and free of obvious noise. They should
remain steady at all times and not flicker for the entire length of the
- Cadence Details: The Blu-ray test disc provides various clips
with different cadences to see how your HDTV and Blu-ray player handles each
- 2-2: The cadence of this clip is 2-2, meaning that there are
2 fields (1 frame) of each image. This is equivalent to 30 fps, which is
commonly used in computer graphic rendered for video and in some
high-speed camera footage.
- 2-2-2-4: The cadence of this clip is 2-2-2-4, which is 2
fields (1 frame) of each of the first three images, then 4 fields (2
frames) of the fourth image, repeating to the end of the clip. This
cadence is a less common way of converting 24p film to 60i video, used
occasionally for film transfers and on some camcorders that have a
- 2-3-2-3 (PF-T): The cadence of this clip is 2-3-2-3, which is
2 fields (1 frame) of the first image, then 3 fields (one frame plus on
field) of the next image, repeating to the end of the clip, This cadence
is the most common one used for transferring 24p film to 60i video. This
version of the clip is encoded using individual progressive frames,
which is more commonly used in professional film encoding. this version
should produce results identical to the alternate version which uses
- 2-3-2-3: The cadence of this clip is 2-3-2-3, which is 2
fields (1 frame) of the first image, then 3 files 91 frame plus 1 field)
of the next image, repeating to the end of the clip. This cadence is the
most common one used for transferring 24p film to 60i video. This
version of the clip is encoded using interlaced fields, which is
somewhat less commonly used in professional film encoding. This version
should produce results identical to the standard version which uses
- 2-3-3-2: The cadence of this clips is 2-3-3-2, which is 2
fields (1 frame) of the first image, then 3 fields (1 frame plus 1
field) of the next image, then 3 fields of the next, then 2 fields of
the next ,repeating to the end of the clip. This cadence is used by a
few camcorders that have a 24p "film-look" mode.
- 3-2-3-2-2: The cadence of this clip is 3-2-3-2-2, which is 3 files
(1 frame plus 1 field) of the first image, then 2 files (1 frame) of the
next image, then 3 fields of the next, then 2 fields of the next, then 2
fields of the next, repeating to the end of the clip, This cadence can
occur when film is transferred at slightly high-than-normal speed,
usually to condense a film for time.
- 5-5: The cadence of this clip is 5-5, which is 5 fields (2
frames plus 1 field) each image. This cadence is the most common one
used when 12 fps animation (often used in TV shows), is transferred to
- 6-4: The cadence of this clip is 6-4, which is 6 fields (3
frames) of the first image, then 4 fields (2 frames) of the next image,
repeating to the end of the clip. This cadence is a less common pattern
used when 12 fps animation (often used in TV shows), is transferred to
- 8-7-8-7: The cadence of this clip is 8-7-8-7, which is 8
fields (4 frames) of the first image, then 7 fields (3 frames plus 1
field) of the next image, repeating to the end of the clip. This cadence
is most commonly used when 8 fps animation (often used for Japanese
anime), is transferred to 60i video.
- 24p: This clip is encoded as true 24 fps progressive, and any
cadence used to convert the 24 fps content to the native display rate is
being done by your Blu-ray player or HDTV. If your player is outputting
24p video, and your display can display it at 24 fps or a simple
multiple of 24 (like 48 or 72 fps), you should see smooth motion with no
stuttering or hitching.
- Difficult Edits: This clip is representative of material that
was originally shot on film, but edited on video. Within each section,
the 2-3 pull-down cadence is perfect, but just before and/or just after
every other edit, the patter is slightly different. All film frames have
been encoded with at least 2 fields, so a good deinterlacer should be
able to reconstruct each original film frame and stay in film mode at
each edit. The image should retain all its resolution and not show any
flicker or artifacts.
- Time-Adjusted: This clips was originally transferred using
standard 2-3-2-3 cadence, then sped up by a small amount by dropping a
field every half-second. This causes the cadence to "break" regularly. A
good deinterlacer should play the clip in film mode with no flickering,
and it should look, essentially identical to the 2-3-2-3 cadence clips.
Edge Adaptive Deinterlacing Clips: In addition, the Blu-ray test disc
provided Edge Adaptive Deinterlacing Clips to evaluate the Blu-ray player's and
HDTV's ability to deinterlace true video content without distracting jagged
stair-step patterns on edges.
- Jaggies: The diagonal edges of the bar shown in this clip should
look clean and not obviously jagged. In addition, the alternating black &
white lines should stay solid and not flicker or turn solid white, black, or
- Bridge: The diagonals of the bridge's cables should be smooth and
solid, and not look like stair-steps or a dashed line. The diagonals on the
flag should be smooth and not stair-stepped.
- Hockey: The diagonal edges of the top of the glass in the
foreground, the lines on the ice, and the edge of the rink in the background
should be smooth and not jagged or stair-stepped.
- Ropes: The thin ropes should be smooth and solid looking, not
jagged, stair-stepped, or broken into small segments.
- Ship: The thin ropes that crisscross the ship and the yellow trim
of the side of the ship should be smooth and solid looking, not jagged,
stair-stepped, or broken into small segments.
- Mixed Film & Video: This clip is designed to test the ability of
the deinterlacer to handle a composite image with two different cadences
overlaid on each other. In this case, a film-cadence clip has scrolling text
over it that is interlaced. A good deinterlacer will recognize that the text
is video encoded and stay in video mode. A bad deinterlacer will lock on to
the cadence of the main video and cause the text to comb badly.
