Chapter 1：SCENE FILE
Scene File: Selecting the preset settings with the dialIn the AG-AC160 series, there are a total of six preset scene files. They can be selected by using the
SCENE FILE dial. These scene files are used to set your camera’s DETAIL, KNEE, GAMMA, DRS,DETAIL CORING / SKIN TONE DTL, CHROMA LEVEL / PHASE, MATRIX / COLOR TEMP, and MASTERPEDESTAL to create an image depending on the recording conditions or you may create your own image.
This is a setting best used for normal HD recording.
F1

The Gamma curve is set to “HD NORMAL” and other parameters are set to the center value.
This setting is best used in recording indoors under cool fluorescent lamps.
Most of the parameters are similar to “F1: Normal” but this mode uses a “FLUO” color matrix table.

F2

FLUO.

“FLUO” matrix table compensates for the recording under fluorescent lighting by adjusting yourcamera’s internal colors.
The “FLUO” matrix may not be required under natural color fluorescent lamps.
This setting creates a better “resolution”, “color level” and “contrast”.

F3

SPARK

Your image will become brighter with richer colors.
Used to highlight subjects at receptions, dinners, etc.
This setting broadens the contrast of the dark parts of the image and is effective for a scene which
has dark & bright areas together (wedding ceremony etc.).

F4

B-STR

This mode expands the gradation at the darker areas (Black Stretch) by assigning a “HIGH” gamma
curve.

Suitable for some shooting locations such as “sunsets” and “in the Theater”.

This setting selects a “CINELIKE V” gamma curve, to shoot a movie-like scene where the contrast is
to be emphasized
F5

CINE VNOTE: Panasonic recommends adjusting the iris to reduce the video level to approximately 1/2 of its
normal level, which will reduce the video level. Used to prioritize contrast
This setting selects a “CINELIKE D” gamma curve to create a movie-like image scene, where
the dynamic range is to be emphasized.

The “CINELIKE D” curve maintains gradations from low

light to a high light level with a higher priority for the dynamic range.
F6

CINE D

When editing the footage in post production or finishing the film, the “CINE D” mode will make it easierand simpler.
NOTE: Panasonic recommends adjusting the iris to approximately 1/2 of its normal level, which will
reduce the video level.

Used to prioritize dynamic range.

Chapter 2：DETAIL
Detail: Edge enhancement concerning the feel of a material, luster, etc.

Detail is a function that enhances contours or edges of an image. It electrically applies artificial image
enhancements to the image’s borders to sharpen the image.

Both Detail Level and Vertical Detail Level

functions are covered in this chapter.
The Detail Level allows you to adjust the image outline correction, both in the horizontal and verticaldirections simultaneously. It basically, adds more detail to your image.
The Vertical Detail Level allows you to adjust the vertical detail only. It basically, adds more vertical detailto your image.
It is important in most cases to maintain a good balance between these two adjustments.

Some people

prefer a higher level of detail and some prefer a lower level of detail. The higher the number (+7) the
more detail compensation (detail enhancement) for the luminance signal.
Keep in mind, once detail is added to the image and recorded, the detail can not be removed.
There are some scenes that Light may reflect slightly on the subject and may enhance or soften the Image.
This may influence the expression of surface luster and quality. Luster of the subjects and the quality canbe expressed by this detail control more naturally.

DETAIL −７

DETAIL ＋７

AG-AC160 is equipped with two DETAIL controls. One is for both the horizontal and vertical directions(“DETAIL LEVEL”).

The other is for the vertical direction (“V DETAIL LEVEL”).

Balance of horizontal

and vertical detail effects can be adjusted by these two controls within a certain range of edge signals.

Adjusting the detail level in the “+” direction from the center value (0) increases the detail level.
outline of the subject is enhanced and the picture becomes sharper.

The

Adjusting the detail level in the “-”direction from the center value (0) decreases the detail level and the outline of the subject becomes softer.

After adjusting “DETAIL LEVEL”, if the balance of resolution between horizontal and vertical seems to beunmatched, adjust “V DETAIL LEVEL” only for vertical detail.

The picture becomes softer with an adjustment in “-” direction, and sharper with an adjustment in “+”
direction.
Setting of V DETAIL
Within a certain variable range, the edge can be enhanced only in the vertical direction.
Especially for pictures of check pattern, this function can be used when there is a gap between horizontal
and vertical resolutions.
・ V DETAIL LEVEL in the SCENE FILE Menu can be set within the range from -7 to +7, and the level ofedge enhancement is adjusted. In combination of adjustments by DETAIL and V DETAIL, it is possible
to enhance the edge balancing horizontal and vertical directions with each other.
Technical Description: DETAIL control
Detail signal is added to the edges on the luminance signal to give an outline enhancing effect. Outline of
the subject becomes sharper when increasing the detail signal level due to the higher level signal at theedges. Outline of the picture becomes softer when decreasing the detail signal level.

Chapter 3：KNEE
Knee: Gradation adjustment

Normally, as the intensity of light increases, so does the signal proportionally, until the signal is limited by
the white clip. The white clip is set to the maximum Allowable video level. The problem with this is that
there is a range of highlight tones, chroma and details that are lost due to the white clip action. The knee
extends the dynamic range by compressing high intensity signals and thus, some detail is preserved in theminor overloads below the clip level.

Depending on the scene, color may become lighter when KNEE

control is adjusted because color gradation is also compressed by the KNEE control.

LOW
The threshold level is to 80%.
When set to 80% and the upper portion of the video signal iscompressed, the color of the sky and clouds can be recognized.
This setup is suitable for scenes that have high intensity areas.
MID
The threshold level is to 90%.
When set to 90% and the upper portion of the video signal iscompressed, the color of the sky is not visible, the image appears
to be whiter and not well separated from the clouds.
HIGH
The threshold level is to 100%.
When set to 100% and the upper portion of the video signal iscompressed, most part of the sky appears white.

However, please be aware that the picture will not be improved even if the KNEE settings are changed
when DRS is working or GAMMA is set in CINE-LIKE.
As for DRS, please refer to Chapter 5.

Technical description:
The KNEE is a function used to allow for higher video levels within the dynamic range of the circuit. It
compresses the signal at a certain level and higher so that the level is within the approximately 109%
(white clip point).

The KNEE function expresses gradations in the high intensity area such as clouds in the blue sky withoutchanging the gradation expression at the knee point and lower.

The KNEE point is a setting for starting level of the KNEE compression. The Adjustable range isapproximately from 80% to 100%, which is typically used by professional video cameras.

The KNEE slope is a slope which is determined by a KNEE point and the maximum level of the dynamic
range.

The AG-AC160 has no manual KNEE slope adjustment, but it is automatically adjusted by setting the
KNEE point.

Generally, for the scenes that have high intensity areas, setting a lower knee point is recommended to
avoid blown-out highlights. For the scenes that have no high intensity areas, setting a higher knee pointis recommended to keep gradations in the middle of the intensity area.

Chapter 4：GAMMA
Gamma: Enriching the hue and gradation

Gamma correction is applied in the camera to correct for nonlinear light-output characteristics of thestandard TV picture tube. The TV picture tube’s gamma stretches the whites and compresses the blacks.
The video Camera’s gamma compresses the whites and stretches the blacks. The Camera’s gamma
can be properly set by using a logarithmic gray scale chart and a waveform monitor.

The Camera’s

gamma must be the reciprocal of picture tube gamma which is 2.2, so camera gamma is usually 0.45.
There are cases where the recorded footage shows different results in “color and contrast” from theoriginal image.
In such cases, adjusting the gradation of the output video signal is effective.

For this purpose, pleasechoose a suitable gamma curve depending on the image.

The following seven kinds of different Gamma curves are available in the AG-AC160.
HD NORM
This is the standard gamma setting for HD shooting.
It is the gamma curve defined as HDTV standard by professionalorganizations such as ARIB, EBU and SMPTE.
Use this mode for shooting the regular HDTV programs.
LOW
The video signal levels in the low intensity areas are compressed
and the Middle-High intensity area is clear. Thus the picture image
becomes sharper.

SD NORM
Use this standard gamma setting for SD recording.
When the camera is used in the SDTV mode or the final program isto be delivered in the SDTV mode, please use this gamma setting.
It is the same gamma curve as used in the AG-DVX100 series
camera recorder.

At the lower intensity areas, the video signal ismore compressed than in the HD NORM mode.
HIGH
The video signal level in the low intensity areas is expanded.
The detail in the dark area is visible in this mode. It provides
brighter tone and soft contrast.
When you have objects in the dark area, this mode is helpful.

©Panasonic Corporation

B.PRESSThe video signal level in the low intensity area is compressed morethan the LOW mode.
The sharp and strong contrast picture is created.

CINELIKE DThis mode creates cinema-like pictures.
It provides a wider dynamic range from low dark areas to brightareas. When the post process is planned, this mode provides thewidest flexibility.
NOTE: Panasonic recommends adjusting the iris to reduce thevideo level to approximately 1/2 of the normal video level.
CINELIKE V
This mode creates cinema-like pictures in the regular video
process.
The rich contrast is applied.
NOTE: Panasonic recommends adjusting the iris to reduce thevideo level to approximately 1/2 of the normal video level.

How to adjust the “GAMMA” control
Select the gamma curve with the following procedures.

1.

Open the “GAMMA” item in the “SCENE FILE” menu screen.

2.

Select a suitable curve from the following selections to record the scene.

HD NORM / LOW / SD NORM / HIGH / B.PRESS / CINE-LIKE_D / CINE-LIKE_V*For utilizing the full characteristic of the CINE-LIKE gamma curves, Panasonic recommends adjusting theiris to reduce the video level to approximately 1/2 of the normal level when the CINE-LIKE_D or
CINE-LIKE_V are used.

Chapter 5：DRS
Dynamic Range Stretcher: Automatic application of the best Gamma

Dynamic Range is the range within which values or variables change.

The dynamic range for images

refers to the luminance range.
In AG-AC160, the Dynamic Range Stretcher (DRS) function automatically estimates and adjusts theGamma curve and Knee slope in response to the signal level of each pixel in real time. Saturated blacks
and Overexposure can be minimized with DRS at the low and high intensity areas in the same scene.
And hue compression can also be minimized.

How to set the “DRS” control
Select the Dynamic Range Stretcher function.
* DRS will not work while in the "slow shutter mode". When using the camera in 1080i, this function can
not be selected in shooting in 24P, 30P, 25P and VFR (Variable Frame Rate).

1.

Select "DRS ON" in "SCENE FILE" menu screen.

2.

Select the value from "DRS EFFECT 1, 2, 3" in “SCENE FILE” menu screen.

The effect level of DRS is more noticeable to your eyes when a higher DRS value is selected.
* When applying a higher DRS value, noise may be seen in the low intensity areas and become visible.
Moreover, depending on the scenes, DRS effects may look unnatural. So please adjust the DRS with avideo monitor to check if the DRS effect on the image is adequate.
In addition, when you assign the “DRS” function to a USER button, you can switch ON/OFF the DRS bypressing the USER button.

1.

From SW MODE menu USER1／USER2／USER3, select a button that you want to assign to.

2.

Select DRS.

Technical Description:"Gamma" is the value to express the relationship between the levels of input and output of cameras orvideo monitors.
In general, it is said that the linear gamma curve ( =1) has the closest image reproduction to human eyes.
However, Gamma characteristic in Cathode Ray Tube (CRT) monitors is not linear (the output level ismuch higher than the input level,=approximately 2.2). To counterbalance the CRT’s gamma

characteristic, the opposite gamma curve ( = 0.45, reciprocal value of 2.2, as the standard gamma value)
is applied in video cameras (gamma characteristic in the eye becomes =1).

Chapter 6：DETAIL CORING /SKIN TONE DTL
Detail Coring
The detail coring is the function of removing noise elements from the detail signal.

This is performed bytaking out the small amplitude signals from the detail signal. The DETAIL CORING setting allows you toadjust the level of the noise reduction of the detail signal. When set to ” –“ the noise increases slightly
and when set to “+” you can reduce the noise.
Skin Tone DetailThe “talking head” is probably one of the most common shots in television. The Skin Tone Detail is used
to improve the head shot quality. When skin tone detail is turned on, the facial skin color has its detail
reduced smoothing to any skin irregularities.
The DETAIL CORING control reduces the noise caused by the DETAIL control, by adjusting the coverage
areas where the DETAIL signal is added.
Image example of DETAIL CORING control
Enhancing the outline with image detail which may
cause noise, coring is added to reduce the noise
and keep original texture.

Example of DETAIL adjustment (without DETAIL CORING control)
DETAIL +7
In this example, the outline and background of thewoman is accentuated.

Also, details of her skinand a strand of the hair is visible.

DETAIL 0
In this example, the outline and background of thewoman is not accentuated. However, the texture of
the skin and hair are kept.

As shown in the photos above, DETAIL and V DETAIL adjustments make changes to texture of the image
unintentionally.

Depending on the scene, the changes to the original texture can be minimized in somedegree by masking the signal enhancement in finer areas with the DETAIL CORING adjustments.

©Panasonic Corporation
12

If the skin area rough, by reducing the amount of detail in the skin area, can create a smoother look with
the SKIN TONE DTL control.
Certain images become flat and lose texture when SKIN TONE DTL is set to “ON” or a higher DETAILCORING value is chosen, Please use a monitor to check the effect of detail coring on the image.
Adjusting the DETAIL CORING control

1. Open "DETAIL CORING" item in "SCENE FILE" menu screen.
2. Adjust the masking level using with the "DETAIL CORING" item from "-7" to "+7".
* When setting a value toward to "-" direction from the center value ( 0 ), the picture image at low signal
level area becomes sharper but the noise level is increased. On the contrary, when setting a value towardto "+" direction, the noise level is decreased but picture image at low signal level area will not beenhanced.
* Adjustment results can be different depends on the recording format and lighting conditions even with thesame setting. Please check the result with a monitor to make sure the DETAIL CORING effect isproperly applied.
Setting the SKIN TONE DTL control

1.

Open “SKIN TONE DTL” menu item in the “SCENE FILE” menu screen.

2.

Set “SKIN TONE DTL” item to ON or OFF

Technical description
DETAIL CORING is used to avoid addition of detail signal noise(controlled by DETAIL / V DETAIL circuit).
The level of noise is relatively smaller than the video signal, enhancing the “noise part” can be avoided by
setting the threshold level to be higher than the noise level with DETAIL CORING control.
With DETAIL CORING control, outline for a certain subject can be enhanced without a grainy image.
Adjusting of the DETAIL CORING may also be effective to reduce noise which appeared by adjusting the
GAMMA correction.
In addition, rough textured skin can be smoothen by setting SKIN TONE DTL to ON.

Chapter 7：CHROMA LEVEL / PHASE
The AG-AC160 series’s color look can be adjusted manually with the CHROMA LEVEL (color saturation)
and CHROMA PHASE (hue). In addition, MATRIX tables and COLOR TEMP controls are also available
for active picture recording. This chapter describes adjustments of CHROMA LEVEL and CHROMAPHASE.
Basically, the Chroma Level adjustment will allow you to adjust the level of the color in the video image
and the Chroma Phase adjustment will allow you to finely adjust the phase or tint (hue) of color in thevideo image.

CHROMA LEVEL adjustment (used to vary color saturation)
The default setting of CHROMA LEVEL is "0".
The value can be set from "-7" to "+7".
Color saturation will become higher when value is increased, andwill become lighter when value is decreased.

CHROMA PHASE adjustment (used to vary the hue)
Setting: +7
Color phase shifts toward purple and magenta hues.
Color look of the women’s face slightly becomes bluish in theexample.

Setting: -7
Color phase shifts toward yellow and green hues.
Color look of the women’s face has more yellow and red umbrella
becomes orange in the example.

Chapter 8：MATRIX / COLOR TEMP
The color look can be actively changed by using the MATRIX tables and the COLOR TEMP (color
temperature) control.
MATRIX
Basically, the MATRIX is used to mix the primary colors red, blue and green to produce the many hues inthe visible spectrum. We often have to compensate for colors, due to lighting conditions.
The Matrix affects the color fidelity of the camera by subtracting an adjacent color. It is a very useful toolin achieving a specific color look.

Remember the white balance and black balance remains unchanged

when any of these Matrix items are changed.
Selecting MATRIX table
1.

Open “MATRIX” in “SCENE FILE” menu screen.

2.

Select a suitable matrix table from “NORM1, NORM2, FLUO, CINE-LIKE” to meet the scene.
NORM1:
Suitable for shooting in the open air or under halogen lamps.
In general, this color look is used in the NTSC area such as Japan
and North America. Always check the color, before deciding to
use this mode.
NORM2
NORM2 has richer color saturation than NORM1.
In general, this color look is used in parts of the PAL area such as
Europe.
Always check the color, before deciding to use this mode.
FLUO:
Suitable for indoor shooting under cool Fluorescent lamps.
This matrix table compensates for the different color temperature(cool light) produced by the fluorescent lamps. This matrix may not
be required under natural color fluorescent lamps.
CINE-LIKE:
Suitable for cinema-like image making.
It is recommended to choose “CINE-LIKE” matrix table when you
select the “CINE LIKE V” or “CINE LIKE D” gamma curves.

Color Temperature
Color temperature generally expresses the color balance of a source of light such as indoor or outdoor
light.

For example, if the temperature is relatively low, the light appears reddish.

As the temperature

increases, the light changes from red to orange to yellow to white. You can set the correct color
temperature.

Setting COLOR TEMP
Please set the COLOR TEMP control, after adjusting the AUTO WHITE BALANCE (Ch A or Ch B) to havethe same adjustable color temperature range even in different scenes.
1.

Open “COLOR TEMP Ach” or “COLOR TEMP Bch” in “SCENE FILE” menu screen.

2.

Doing fine adjustment of color temperature from “-7” to “+7”, center value is “0”.

The following scenes are recorded in the evening. You can use these looks or effects at other locations ortime of the day by using the COLOR TEMP control.

Chapter 9：MASTER PEDESTAL
Pedestal or Setup determines the record setup level and can be seen as a direct readout in IRE units on a
waveform monitor. In standard analog video the Pedestal is normally set at 7.5 IRE or 7% and in digital
video it is set at 0 IRE or 0%, this is the black reference for the video signal.

This adjustment allows theuser to slightly control the pedestal level which is set in the Camera Setup Menu. This will change theblack reference for the video signal and allow for either slightly rising of the blacks or the crushing of them.
In video signal, the minimum black level is called “Master pedestal” and it is a reference of the luminance.
MASTER PED control lifts pedestal (black) level and affects brightness balance of the image.
Gradation controls can be used together with outline controls to give a sharper or softer tone to an
image.
