Introduction

Welcome to the Model 1200 Operation manual. This manual will help you get the most out of the power built into the compact Model 1200. You can either use the manual as a tutorial to help you learn the switcher, beginning with this section and working your way to the end, or you can use the book as a reference tool to answer occasional questions.

Also, don’t overlook the Quick Reference Guide tucked into the pocket inside the front cover of this book. The Quick Reference Guide presents operating procedures in the shortest possible form. If you are an experienced operator who wants only a quick overview of operating procedures and an occasional reminder, the Quick Reference Guide may be all you will need.

Section 1— Introduction

Features of the Model 1200

The Model 1200 Digital Production Switcher is a moderatelypriced yet powerful one mix/effects component digital mixer. It offers the tremendous advantage of digital video as well as many desirable mixing and special effects features:

Ten-bit component digital format for excellent signal quality

■

and virtually unlimited effects layering. Aspect ratio can be set for 4:3 or 16:9 (13.5 MHz).

Up to 16 digital video or key inputs plus internal black and

■

background. Optional inputs may be parallel, serial, or some of each. Inputs may be auto-timed, mapped to crosspoints, and level-adjusted by built-in processing amplifiers.

Ten Crosspoint Switching Buses: Program Background,

■

Preset Background, Key 1 Source and Fill, Key 2 Source and Fill, DSK Source and Fill, Auxiliary 1, and Auxiliary 2.

■

One effects keyer and one downstream keyer plus an optional second effects keyer. Each keyer creates luminance, linear, preset pattern, and chroma keys (optional) from inputs selected on the Key Bus. Keys can be inverted and masked.

1-2

■

Optional Chroma Keyer accepts 4:2:2 or 4:4:4 inputs. Includes adjustable background and foreground suppression and choice of additive or multiplicative key.

■

Effects transition controls include cut, lever arm, and frameaccurate automatic transition. Effect modes include Mix, Wipe, and Cut. Effects backgrounds and keys can be transitioned on or off separately or simultaneously.

■

Separate DSK controls include cut, frame-accurate automatic mix, and frame-accurate fade to black.

■

Effects key layers can be adjusted for opacity and priority of one key over another.

■

Z-Key™ Depth option accepts depth keys from Grass Valley digital effects systems for compositing intersecting plane effects with adjustable offset. Non-depth keys can be offset so that new layers can be recorded between existing layers.

Features of the Model 1200

■

Depth option includes Layered mode that composites both M/E keys onto the switcher Key output.

■

Effects Send enables flying switcher effects keys over switcher backgrounds using an external Grass Valley digital effects system. (Requires Effects Send/Aux Output option.)

■

Borderline® Key Edger option available for each keyer includes borders, drop shadows, outlines, and extrusions.

■

Wipe/mask system includes twenty patterns with H and V multiples and matte edge adjustable for width, softness, and softness symmetry. Patterns can also be adjusted for position, aspect, rotation, and modulation. New approach to pattern generation provides smoother wipe transitions.

■

Many internal mattes available, including background matte, matte fill for each keyer, separate matte for each Borderline mode, wipe edge matte, preset pattern edge matte, and mattes generated by any number of crosspoints if enabled via menus.

■

Twenty panel-operated E-MEM® registers provide storage and recall of effects and auto transitions.

Contact-closure GPI interface includes 8 inputs for external

■

triggering of switcher functions and 8 outputs for switcher triggering of other devices. Outputs can be synchronized with switcher transitions.

■

Sixteen tally relay outputs. Four serial ports for serial interface to an editor, a DPM, and

■

other external devices. Optional preview system for previewing effects.

■

Optional parallel digital or serial digital outputs.

■

Optional component analog monitor outputs. Built-in panel display includes menus, soft knobs for

■

Section 1— Introduction

Model 1200 Overview

The Model 1200 architecture (Figure 1-1) consists of a single mix/effects system with two keyers and a downstream keyer. Video inputs selected on the background crosspoint buses enter a pair of program and preview mixers. Video and key inputs selected on the key crosspoint bus are first processed in the keyer circuits. If effects send mode is off, the keyer outputs go directly to the mixers, and any aux bus selections go directly to the aux outputs. If effects send mode is on, the key and fill outputs of one of the keyers are routed via the aux bus outputs to a DPM, and the

You might be tempted to skip over the “Concepts” part of this section, especially if you are an experienced switcher operator. Nevertheless, we advise you to read it anyway because it explains operating concepts specific to the 1200 switcher that will help you to more fully understand how the 1200 works.

System Startup or Restart

Startup

1. Set the 0/1 power switch inside the front cover of the switcher frame to the 1 (on) position.

2. Set the 0/1 power switch inside the switcher control panel to the 1 (on) position.

This applies power to the entire system, which will boot up and become operational in a few seconds. To power down the system at any time, just switch both power switches to 0 (off).

Restart

If the system becomes confused or locks up, you can restart it as explained below. The effect you were working on will be lost, but E-MEM contents and conﬁguration ﬁles will remain intact.

Concepts You’ll Need to Know

There are a few basic concepts that you should know before you begin setting up and operating the switcher. These concepts are presented on the following pages.

Delegation

Some switcher functions, when selected, automatically activate related subpanels or functions. This is called example, when you press the subpanel, the Keyer subpanel delegates to control Keyer 1. Related functions delegate in logical ways, making operation easier because fewer button pushes are required.

Sometimes, even with the help of automatic delegation, you must still delegate a function manually. If a subpanel or function doesn’t respond when you operate it, check that it is delegated to the function you are trying to control.

each with a different video or key input and a common output called a connecting to the output. The outputs of the various buses feed the switcher’s effects and transition circuits.

There are a number of buses in the Model 1200, including the PGM (Program) and PST (Preset) background buses, the Key buses, and the Aux (auxiliary) buses. The background buses feed the video mixers, allowing you to select background sources and do transitions between them. The key buses feed the keyers, allowing you to set up keys, which are also fed to the mixers for keying over the background. Lastly, the aux buses select signals and send them directly to a switcher output for feeding external devices, such as digital picture manipulators; this makes the same inputs that are available to the switcher also available to the external devices.

Cut Transition

cut

is an instantaneous switch from one picture to another. A background cut, for example, switches the Program (on air) output of the switcher instantly from the picture selected on the Program bus to the picture selected on the Preset bus. A cut can also be used to switch a key on or off air instantaneously.

Mix Transition

mix

is a transition from one picture to another where the new picture mixes into and then replaces the picture that was already on air (Figure 2-1). The Model 1200 allows you to mix from one background picture to another or to mix up to three separate key layers on or off over a background. Background and effects key mixes can be done separately or simultaneously.

Wipe Transition

wipe

is a transition from one picture to another where a shaped edge moves across the screen revealing the new picture (see Figure 2-2). A background wipe removes the old Program Background picture as it wipes on the new Preset Background picture. A key wipe reveals the key over the existing background or removes it without affecting the existing background. In the Model 1200, a wipe can also change the background and the effects key(s) at the same time.

Wipes can take the shape of any of the twenty available patterns, which can be adjusted for position, aspect ratio, multiples, rotation, modulation, edge width, edge color, and edge softness.

Key

A key is an effect in which parts of one picture are inserted into another to create a composite picture. For example, keys are used to insert captions, to place a small news scene or graphic over the shoulder of a newscaster, or to place the image of a weather reporter in front of a weather map. There are several types of keys, each of which serves a different purpose.

To use an example, suppose we want to insert a green logo into some background video. We could print the logo in white on black paper and then focus a camera on it. We can then apply the signal from the camera to the switcher’s keyer where it will be used as a key signal. Next we can select a green matte video to apply to the keyer as the fill video. When the clip is set properly, the keyer will ignore the black paper and use only the white logo shape to cut a hole in the background video. Then it will fill the logo-shaped hole with green matte video. This creates a green logo inserted into the background. In actuality, this method of keying is seldom used anymore. Instead, a graphics system generates the key and fill video, but the same concepts apply.

Luminance keyers also include a sharpness of the transition from one picture to another at the key’s edge; high gain yields a sharp edge, and low gain yields a soft edge that mixes the fill and background video. In addition, the Model 1200 keyers include an S-shaping function that prevents the transition at the key edge from becoming too sharp and creating what appears to be a band or line around the key.

Using the Keyer menu, the clip and gain controls can be changed to control foreground clip and background clip. In that case, the controls independently adjust the transition edges of the foreground fill video and the background video.

Anti-aliased sources, such as the output of a character generator or graphics system, have soft edges that produce a mix between the fill and the background at the key edge. A linear key preserves this edge.

the background of a scene is detected and replaced with a new background scene. This gives the illusion that foreground objects are positioned in front of a new background. For example, the fill video selected on the Key bus may be a weather reporter standing in front of a blue wall, and the new background video may be a weather map (Figure 2-4). The completed chroma key consists of the weather map background where the blue wall used to be and the reporter foreground fill everywhere else. This creates the illusion that the reporter is standing in front of the weather map.

A convenient feature of the 1200 chroma keyer is automatic setup, which sets up the key for you when you identify the background color that you want to replace by positioning a cursor over the color using the joystick and pressing the button on the top of the joystick. In most cases, this function yields a very good chroma key, which you can use as is or fine tune as desired using the Keyer controls and the Chroma Key menu controls.

is a key in which a particular color that you select in

2-8

The Model 1200 chroma keyer includes background and foreground suppression. Background suppression replaces the old background color with black before adding in the new background. This ensures that the old background color is completely removed from the scene, resulting in a cleaner key. Foreground suppression is essentially a second chroma keyer that allows you to detect and remove the background color and its variations that “splash” onto foreground objects, as sometimes happens when the foreground object is placed near the background. The detected foreground “splash” color is replaced with a neutral color and luminance value that restores the natural color of the foreground object.

Concepts You’ll Need to Know

Both background and foreground suppression include menu controls for selecting the hue to be replaced and for adjusting the luminance and chrominance levels in the areas of the picture where suppression is applied.

Also included in the 1200 chroma keyer are a shadow processor and a box mask. The shadow processor adjusts the amount of shadow that chroma key foreground objects cast onto the background, making the key look more natural. The box mask, controlled from the Chroma Key Force Mask menu, can be sized and positioned over a part of the key foreground or background to prevent the key from occurring in that area.

Lastly, an Edge Control menu allows you to adjust the size (both width and height) of the key edge in the black suppressed part of the background. Adjusting for optimum key size ensures that none of the black background suppression is visible along the key edges.

Shaped Video

Shaped video

create a partial-raster image that is matted over black. A good example of shaped video is the fill video output of some character generators, which consists of characters on a black matte. Typically, the shaped fill video is also accompanied by a matching key signal that may be used in a keyer to cut a hole in background video into which the already-shaped fill video may be inserted.

The 1200 configuration menus ask you to identify video inputs as shaped or unshaped because the switcher handles those two types of fill video signals differently. For keying with shaped fill video, the keyer multiplies only the background video with the key signal to cut a hole in the background, and then adds the alreadyshaped fill video into the hole. For fill video that is not already shaped, the keyer first multiplies both the background and the fill video with the key to cut a hole in the background and shape the fill to match the hole. Then the background video and the fill video are added together to create the finished key.

If you incorrectly identify the type of fill video in the Define Inputs configuration menu, selecting shaped when you should select unshaped or vice versa, your keys will have dark lines at the edges or other artifacts. Changing the video type in the Define Inputs configuration menu will correct the problem.

Effects Send

2-10

Effects Send provides a close interface between the switcher and a digital picture manipulator (DPM). Effects Send takes the key and fill video outputs of an effects keyer and sends them to the DPM for manipulation. The manipulated key and fill outputs from the DPM then re-enter the switcher’s mixers via the aux buses.

The Effects Send advantage lets you transform a switcher key effect, such as a chroma key or a preset pattern, as though the DPM circuitry were built into the middle of the switcher: The transformed key can be layered over a switcher background and additional keys can be layered on top of the transformed key.

Z-Key™ Depth

Concepts You’ll Need to Know

The Depth option enables the switcher’s two effects keyers to key a depth key input from a Grass Valley digital picture manipulator over a switcher background. Depth keying creates an effect in which one key layer appears closer to the viewer than a second key layer does, and one key layer can “slice” through the other.

The Depth option also works with ordinary key signals. You can assign different depth values to the two M/E keys and record them. Then you can play the composite effect back and insert additional key layers between the original two layers. The keys cannot be made to intersect, and they may not create the visual illusion of depth the way a true depth key does, but you can composite multi-layered graphics with layers that slide in and out between other layers.

In order to record a depth key, a 10-bit digital recorder with two channels (video and key) is required to retain depth information.

E-MEM® Effects Memory

E-MEM Effects Memory provides a way of storing switcher effects for later use. With E-MEM you can set up an effect and “learn” a snapshot of it into memory. Later, you can recall that effect at the touch of a button, and the switcher will immediately return to the state it was in when the effect was learned.

You can also learn automatic transitions as part of a stored effect. When you learn an auto transition with an effect into a register, recalling that register recalls the effect first, and then starts the stored transition automatically.

The E-MEM system includes 20 effects storage registers arranged in two “banks” of ten registers each. E-MEM register contents can be saved to disk using the floppy drive and menu display.

to display the Define Inputs menu (Figure 2-8). This menu is typically configured during switcher installation. However, you may want to change configurations for different types of production sessions. The Inputs menu allows you to do the following:

■ Give each physical input a descriptive name which is carried

forward into several other menu levels.

■ Attach characteristics to each physical input, such as bit

resolution of the source, identification of the signal type, and association of key cutters with fills. The signal type tells the switcher whether the input is to be treated as video, shaped video, key, or key with depth.

■ Designate a video/key pair as the return inputs in systems

where an effects send and return will be used. This information is needed by the switcher for automatic switching of the effects loop. (See the explanation of Effects Send later in this section for details.)

■ Select 4:2:2 chroma key inputs or full-bandwidth 4:4:4 chroma

key inputs. Two physical inputs are needed to accommodate a full-bandwidth chroma key signal. The Inputs/4:4:4 CK Sources sub-menu designates those two physical inputs.

System Setup: Using the Configuration Menus

Input timing is automatic; however, you can adjust the overall timing manually in the Timing menu (Figure 2-13) to ensure that auto-timing captures all inputs. When you make this adjustment, you are advancing or delaying the Reference input, which causes a corresponding movement of the auto-timing capture window for the primary inputs and also causes a corresponding movement of the switcher outputs.

GPI Menus

The GPI Inputs menu (Figure 2-15) is displayed when you press the [Conﬁg] top menu button followed by the

[GPI>]

soft button. From this menu, you can view the GPI Inputs or access the GPI Outputs menu (Figure 2-16). Together, these two menus allow you to assign, view, and test the 8 GPI inputs and 8 GPI outputs.

GPI inputs are trigger signals that come from external equipment (via the GPI connector at the back of the frame) and start a specified event in the switcher, such as an auto transition. GPI outputs are trigger signals generated by switcher events that go out via the GPI connector to external devices to cause them to take some action. You can assign events to the GPI Inputs or Outputs as follows:

1. Display the GPI Input or Output menu.

2. Change the event assigned to a GPI using the

INPUT/OUTPUT)

soft knob to highlight the desired input or

(SELECT GPI

MAP

selection allows you to use a GPI input to switch between

ALTERNATE XPT

two different crosspoint maps stored in the Input Map menu. This can be convenient when you have two different uses for the switcher, for example, a live news show and off-line post production. The

AUX BUS TALLY BACK

selection uses the GPI as an input condition that the switcher detects in order to tally the selected aux bus crosspoint. This permits an external DPM to tally the aux buses when aux bus video is on air at the DPM. Aux tallyback can be turned on and off in the Tally menu.

When set to ON, the

Bus Delegates

The Bus Delegates section of the panel (Figure 3-2) includes the [AUX 1] and [AUX 2] pushbuttons, representing the two internal Auxiliary crosspoint buses. When you select one of these buttons, the Aux crosspoint row delegates to control the selected bus. Only one of the Aux buttons may be on at a time. Also, turning on an Aux Delegate button cancels Effects Send if it was on.

Crosspoint Buses

The crosspoint buses include crosspoint buttons for selecting video and key sources for backgrounds, keys, and auxiliary bus outputs. See Figure 3-3 on page 3-6. The crosspoints operate as follows:

■ Video and key input sources are “mapped” or assigned to

crosspoint columns in the Config/Crosspoint Map menu. In addition, inputs are defined and assigned names in the Config/Define Inputs menu.

■ To select an input on any bus, press the [CROSSPOINT]. The

selected input will be routed to the bus output.

■ Crosspoints light brightly (high tally) when contributing to

the on-air Program picture. They light dimly (low tally) when selected but not on-air.

■ Each crosspoint can generate its own internal matte instead of

selecting a video or key signal, if so assigned in the configuration menus. To adjust the color of a BKGD or matte, press the [CROSSPOINT] button to delegate the Matte controls and then adjust the Matte controls for the desired color.

■ Each crosspoint bus includes an adjustable signal processing

amplifier if enabled in the configuration menus. When you double-press a video or key crosspoint, the Proc Amp menu appears, allowing you to adjust signal levels for that video or key source. As you adjust levels, the UNCAL lamp at the end of the bus lights to indicate that the proc amp is no longer at the default unity setting. To reset the proc amp to the default unity setting, press the

[CLEAR PROC AMP]

menu button,

or hold the crosspoint button down and press the [CLEAR] button in the E-MEM panel area.

PST (Preset) Bus

PST bus crosspoints select the background video that will be placed on air by the next background transition.

PGM (Program) Bus

PGM bus crosspoints select the background video that is on air at the switcher’s Program output.

■ You can select a PGM crosspoint directly; this causes an

immediate cut to the new video.

■ Or you can select a source on the PST bus and then do a

background transition to transfer the Preset selection to Program.

At the end of a background transition the PGM and PST selections “flip-flop”—the PST source transfers to PGM, and the PGM source transfers to PST.

Crosspoint Buses

Key bus crosspoints select the fill video and key source used by the delegated keyer to create a key. Each crosspoint can be assigned a fill video and a key source via the configuration menus.

■ Before selecting a crosspoint, you must first delegate a keyer

by pressing the [KEY 1], [KEY 2], or [DSK] button in the Keyer or Transition section. Then select a crosspoint and make any other desired Keyer selections and adjustments.

■ When [VIDEO KEY] is on, the switcher does a self key: the fill

video you select on the Key bus also serves as the key source (cuts the hole and fills it).

■ When [AUTO SELECT KEY] is on, you select the fill video

crosspoint on the Key bus, and the switcher will automatically select the assigned key source.

■ You can also do a split key (use different fill and source

crosspoints): Select a Key bus fill [CROSSPOINT], hold down the [AUTO SELECT KEY] or [VIDEO KEY] button, and select another Key Bus [CROSSPOINT] to serve as the key source. The fill button and SPLIT KEY lamp light up and remain lit; the source crosspoint lights whenever you hold down the [AUTO SELECT KEY] or [VIDEO KEY] button.

A split key is temporary and does not change the key assignments mapped in the configuration menus during system setup. To cancel the split, press any Key bus [CROSSPOINT] or hold down [Auto Select Key] or [Video Key] and press the fill [crosspoint].

■ Every Key bus crosspoint has Key Memory, if enabled in the

Keyer menu. When you select a crosspoint, Key Memory restores the last keyer setup used for that crosspoint. Remembered functions include key source type (Video or Auto); key type (Linear, Luma, Chroma or Preset Pattern); and the various control knob and menu settings.

Section 3 — Controls & Menus

Aux Bus 1 and Aux Bus 2

The single row of Aux bus crosspoint pushbuttons controls two separate auxiliary crosspoint buses, Aux bus 1 and Aux bus 2. The Bus Delegate buttons control delegation of the aux row to control Aux bus 1 or Aux bus 2. After delegating the Aux row to the desired Aux bus, selecting a crosspoint in the Aux row causes the corresponding Aux 1 or Aux 2 bus output to cut to new video.

When one of the Effects Send buttons is selected, the Bus Delegate buttons turn off, and both aux buses become dedicated to the Effects Send signals. The Aux buses then serve as the return input path for preprocessed switcher video and key signals that have been looped through an external digital picture manipulator before entering the keyer. The switcher automatically selects the correct aux crosspoints according to the Effects Send crosspoint map assigned in the configuration menu.

Satellite Aux Bus Panels

3-8

When an optional Model 1200 or Model 200 Satellite Aux Bus Panel is connected to a switcher serial port and enabled in setup, the satellite panel has direct control over the aux buses. To select an aux crosspoint on the Satellite Panel, delegate an aux bus by selecting [AUX 1] or [AUX 2] and then select a Satellite Panel [CROSSPOINT]. Eighteen of the available Satellite crosspoints are assigned to the same video, key, black, and background inputs as the other switcher buses. The remaining crosspoints can have mattes assigned.

Downstream Keyer (DSK)

The DSK (Figure 3-4) inserts titles or other keys on top of the switcher’s background and effects key layers. The DSK is a fullfunction keyer, capable of luminance, linear, chroma, and preset pattern keys just like the effects keyers.

■ To delegate Keyer and Key bus controls to the DSK, select

[DSK] in the Keyer section or select [DSK PREVIEW] on the DSK panel. The DSK lamp at the end of the Key bus will light.

■ Select key fill and source [CROSSPOINTS] using the Key bus.

■ Select and adjust key parameters using the Keyer controls.

■ Transition the key on and off using the [DSK CUT] or [DSK MIX]

button or using the [CUT] button in the Keyer section. When the key is on, the DSK ON lamp lights.

Effects Send

The Effects Send panel section includes three buttons to enable the Effects Send option for any one of the three keyers: [KEY 1], [KEY 2], or [DSK]. See Figure 3-5.

When you select an Effects Send keyer button, Effects Send mode turns on for the selected keyer, the Keyer controls delegate to the selected keyer, and the Aux buses delegate to Effects Send. Only one keyer can use Effects Send mode at a time. This mode routes the key and fill video outputs of the keyer outside the switcher to a digital picture manipulator (DPM), which transforms them and returns them to the switcher’s mixer via the aux buses.

■ To cancel Effects Send, press either of the Bus Delegates

buttons, [AUX 1] or [AUX 2]. This turns off Effects Send and delegates the Aux row to the selected Aux bus.

Key Source Type: Video Key and Auto Select Key

The [VIDEO KEY] and [AUTO SELECT KEY] pushbuttons select the type of key source that will cut a hole in background video to create a key effect. Only one of these buttons may be on at a time.

The [VIDEO KEY] button enables a self key in which the fill video selected on the Key bus serves as its own key source.

The [AUTO SELECT KEY] pushbutton enables automatic key source selection for the fill video that you have selected on the Key Bus. In this mode, you select the fill video crosspoint, and the source that will be used automatically is the one that was preassigned for use with that fill video in the configuration menus.

Split Key

You can do a split key (use different fill and source crosspoints) for either key source type. To split the key:

■ Select a Key bus fill [CROSSPOINT].

3-18

■ Turn on and hold down either the [VIDEO KEY] button or the

[AUTO SELECT] button. [VIDEO KEY] uses the fill from the

second Key bus crosspoint that you select as the key source. [AUTO SELECT] uses the auto select key source from the second crosspoint that you select as the key source.

■ Select another Key Bus [CROSSPOINT] to serve as the key

source.

The split source crosspoint lights when you select it, and lights whenever you hold down the [VIDEO KEY] or [AUTO SELECT] button. In addition, the Split Key lamp turns on to indicate a split key.

To turn off a split key, press any Key bus [CROSSPOINT], or turn off the current key source type by pressing the other source type button.

Key Fill: Video or Matte

Using the [VIDEO FILL] and [MATTE FILL] buttons you can choose to fill the key with video or matte. Only one of the two buttons can be selected at a time. In either case, the signal is supplied by selecting a Key bus crosspoint that has been designated as a video fill or a matte fill.

Key Type: Linear Key, Luma Key, Chroma Key, and Preset Pattern

For any of the switcher’s three keyers you can select from among four key types: [LINEAR KEY], [LUMINANCE KEY], [CHROMA KEY] (optional), and [PRESET PATTERN]. Only one of these types can be selected at time. Double-pressing any of these buttons brings up a related display menu. For details about menus and adjustable controls relating to these four buttons, refer to the Key Modifiers section that follows and to the menu descriptions at the end of this chapter.

Keyer

Linear Key

Selecting [LINEAR KEY] produces a luminance key with a gain near unity and no key edge shaping. A linear key is generally used for keying from anti-aliased characters or graphics. The fill and source are taken from the Key Bus. Adjustments and modifiers include (CLIP), (GAIN), (KEY OPACITY), [KEY MASK], [KEY INVERT], optional Borderline edge effects, and additional adjustments in the Keyer menu. If you adjust the gain away from unity, the [LUMA KEY] button lights to indicate that the key is no longer exactly linear.

3-19

Section 3 — Controls & Menus

Luma Key

Selecting [LUMA KEY] produces a high gain key with key edge shaping. Luminance keys are generally used when keying from video. The fill and source are taken from the Key Bus. Adjustments and modifiers include (CLIP), (GAIN), (KEY OPACITY), [KEY MASK], [KEY INVERT], optional Borderline edge effects, and additional adjustments in the Keyer menu.

Chroma Key and Auto Setup

Choosing [CHROMA KEY] activates the optional chroma keyer and the Chroma Key menu. The chroma keyer removes a user-selected color from the Key Bus fill video, producing a key effect that consists of background video where the color used to be and fill video everywhere else. Note that the chroma keyer can be used in only one keyer at a time. If it is in use in one keyer when you select it in another keyer, the key type lamps turn off and the key layer is forced to be transparent.

When [CHROMA KEY] is on, you can select [AUTO SETUP], a feature that provides fully automatic adjustment of the chroma key. When [AUTO SETUP] is on, a cursor appears on your Program video monitor. You may then use the joystick to position the cursor over the color you wish to key out, and press the button on the top of the joystick to select that color. The switcher automatically adjusts the chroma keyer to produce an excellent chroma key based on the color you select, and the [AUTO SETUP] button turns off, indicating that auto setup has been accomplished. To turn off [AUTO SETUP] without selecting a color, just press the [AUTO SETUP] button again.

3-20

You can also adjust the chroma keyer controls directly if you choose to. Adjustments and modifiers include (CLIP), (GAIN), (KEY OPACITY), [KEY MASK], [KEY INVERT], and a number of controls in the Chroma Keyer menu, including a dedicated chroma key box mask. (See the menu descriptions later in this section.)

Preset Pattern

The [PRESET PATTERN] button enables a wipe pattern to cut the key hole and assigns the Key bus to provide the fill video. Note that preset patterns and wipe transitions share the pattern generator. Changing the wipe pattern changes the preset pattern also.

When you select [PRESET PATTERN], the Matte and Pattern controls delegate to preset pattern adjustment. You can use these controls to select a pattern, invert the key, set pattern position (joystick), pattern (SIZE), edge (WIDTH), edge (SOFTNESS), and edge softness (SYMMETRY). Additional adjustments are available in the Wipe menu. Using the Matte controls, you can adjust the pattern edge luminance (LUM), saturation (SAT), (HUE), and (KEY OPACITY).

Key Modifiers and Adjustments

Key modifiers and adjustments are listed and explained below. Additional modifiers and adjustments not listed here are available in the Keyer, Chroma Key, and Wipe (Preset Pattern) menus.

Keyer

Key Over

The [KEY OVER] button, when activated, places the currently delegated effects key layer on top of the other effects key layer.

Invert

Selecting [INVERT] inverts the polarity of the key source. For a luminance or linear key this enables the dark areas of the source to cut the key hole rather than the light areas, which is helpful when keying from dark images on a light background.

3-21

Section 3 — Controls & Menus

Mask

When you select [MASK], a mask created by the pattern generator inhibits the key (forces the background on) wherever you place the mask. This allows you to prevent keying in parts of the picture where you don’t want it to occur.

When you select [MASK], the Pattern controls delegate to control the mask. Masking occurs in the areas indicated by black on the pattern buttons, but if [MASK/PRESET INVERT] is on, masking occurs in the areas indicated by white on the buttons.

Note that masks and wipe transitions use the same pattern. If you change wipes, the mask pattern will change also.

Force Mask

The [FORCE MASK] button serves the same purpose as the Key Mask, but it uses a box mask rather than a pattern, and it is dedicated to the chroma keyer. The box mask position, size, and aspect can be adjusted via the Chroma Key Force Mask menu.

3-22

Show Key

When pressed, [SHOW KEY] fills the key with white for better edge visibility during setup. Pressing it a second time toggles it off.

Key Opacity

The (OPACITY) control sets key layer translucence. Counterclockwise increases transparency; clockwise increases opacity.

Keyer

Gain and Clip

The (GAIN) control sets keyer response at the key edges. Setting (GAIN) low yields a more linear response to the key source,

preserving gradual or anti-aliased key edge transitions. Setting it high increases key gain, producing sharp key edges.

The (CLIP) control sets the threshold of keyer response to the key source. Only those areas of the source that have a higher luminance level than the clip threshold can cut a key hole in the background and cause foreground fill video to appear. All areas of the source below the clip threshold will not cut a hole, and background video will remain visible.

In the Keyer menu, (CLIP) and (GAIN) can be assigned to operate as (FGD CLIP) and (BKGD CLIP) controls, providing independent foreground and background thresholds, which results in finer edge control (Figure 3-10). The (CLIP) control sets a foreground clip level so that any part of the key source with a luminance level above that threshold will cause foreground fill video to appear in the key effect. The (GAIN) control sets a background clip level so that any part of the key source with a luminance level below this lower threshold will cause background video to appear.

Borderline

The Borderline® option adds border, drop shadow, extrusion, or outline edge effects to keys (Figure 3-11). This option can be added separately to each keyer. Control for all of the Borderline options is provided by one set of buttons that delegate with the Keyer panel:

■ Four border types are available (see below). Only one border

type can be selected at a time.

■ To change height or width of an edge effect, hold down one of

the four border mode buttons and use the (POSITIONER), which delegates automatically.

■ To change the color or opacity of an edge effect, adjust the

MATTE controls, which delegate automatically.

Normal

The [NORMAL] button selects a key with no edge effect.

Border

3-24

When you select [BORDER], a matte edge is placed all around the key. Width of the edge is 1–3 lines.

Shadow

When you select [SHADOW], a matte edge appears below and right or left of the key. Height is 1–6 lines and width is 1–60 lines.

Extrude

When you select [EXTRUDE], a matte edge appears that looks like a layered drop shadow, creating a block letter effect. Height of the edge is 1-6 lines and width is 1–60 lines.

Outline

When you select [OUTLINE], the area inside the key disappears, leaving only a matte edge 1–3 lines wide.

Key Memory and Key Copy Features

The key memory feature built into the control system remembers the complete keyer setup used last for each Key bus crosspoint. All you have to do is select a Key bus crosspoint, and the Keyer setup used last with it will be restored. Key Memory can be enabled or disabled in the Keyer menu.

Matte

The switcher has many matte generators, including matte fill, wipe border, Borderline, and a background matte generator within each crosspoint which can be enabled in the Config/ Crosspoint Map menu. The four Matte controls (Figure 3-12) can be delegated to adjust any of the available mattes.

Matte Controls

■ The (HUE) knob sets the matte color.

■ The (SAT) knob sets the color saturation.

■ The (LUM) knob sets the color brightness.

■ The (OPACITY) knob sets the translucence of the matte. At the

fully clockwise setting, the matte is completely opaque.

Selections in the menu system allow you to limit the matte generators to produce only levels and colors that fall within broadcast and RGB color standards.

3-26

Matte Delegation

Delegation is automatic when you select a matte crosspoint. In addition, delegation buttons and a display are provided in the Matte panel section for manually delegating the control knobs:

■ The [BKGD], [WIPE BORDER], [KEY 1], [KEY 2], and [DSK] buttons

delegate the matte controls to the background generator, the wipe matte generator, or the key matte generators, respectively.

■ The [FILL], [PRESET BORDER], and [BORDERLINE] buttons

provide further subdelegation of the Matte knobs to the keyer’s matte fill, preset pattern border matte, or Borderline matte.

Pattern Adjustments

Available pattern adjustment controls are described below.

Positioner (Joystick)

The positioner controls operate as follows:

■ Turning on the [POS] button enables the positioner and

returns the pattern to the position it was last moved to. You can then use the positioner to move the pattern to any screen position. Turning off the [POS] button disables the positioner.

■ When you press the [CENTER] button, the pattern returns to its

default center position.

Wipe Direction

The three wipe direction buttons are [NORMAL], [REVERSE], and [FLIP FLOP]. Normal and Reverse modes cannot both be selected at

the same time. However, Flip Flop mode works in combination with either Normal or Reverse.

3-30

■ When [NORMAL] is on, the white areas on the pattern buttons

indicate new video that will be revealed as the pattern moves.

■ When [REVERSE] is on, the black areas on the pattern buttons

indicate new video.

■ When [FLIP FLOP] is on together with one of the other buttons

(Normal or Reverse), the first wipe transition moves in the direction indicated by the other lighted button. Then the next transition moves in the opposite direction (flip flop). This feature allows you to “wipe on” and “wipe off” using whichever starting direction you choose.

Mask Preset Pattern/Wipe

The [MASK/PRESET PATTERN] and [WIPE] buttons delegate the (WIDTH), (SOFTNESS), (SYMMETRY), and [MASK/PRESET INVERT]

controls to a mask or preset pattern key or to a wipe pattern. Only one of the two buttons may be on at a time.

Pattern

Size and Border Width, Softness, and Symmetry

■ Patterns can have a matte-filled border if you turn on the

[BORDER] pushbutton. When [BORDER] is on, the (WIDTH) knob sets the width of the border. The Matte controls set the edge color.

■ When you turn on the [SOFT] button, the (SOFTNESS) knob sets

the diffusion of the pattern edge. When the [SOFT] button is off, the pattern has a hard edge.

■ If the [SYMM] and [SOFT] buttons are both on, the (SYMMETRY)

knob sets the balance or evenness of the softness applied to the pattern edge. When the [SYMM] button is off, softness of the edge is evenly balanced. When the [SOFT] button is off, the symmetry control has no effect.

Mask/Preset Invert

When you select a mask or preset pattern, you can toggle the [MASK/PRESET INVERT] button to change the area of the picture that is affected by the mask or fill video. When the invert function is off, the white area on the pattern buttons represents the area of the screen where masking occurs or where the fill video appears. When the invert function is on, the black area on the pattern buttons represents the area of the screen where masking occurs or where the fill video appears.

Wipe Menu

When you press the [MENU] button, the Wipe menu appears in the menu display. This menu provides access to additional wipe patterns as well as additional pattern modifiers, including aspect ratio adjustments, sine wave modulation of the pattern, pattern rotation, and pattern multiplication.

The [BKGD], [KEY 1], and [KEY 2] pushbuttons delegate the transition controls to the effects keyers and/or the PGM/PST background mixer. You can select one button or push multiple buttons simultaneously. The selected buttons light and the others turn off automatically. The next transition affects only the lit functions.

Bkgd

The [BKGD] button selects the background transition mode and delegates the transition controls to the PGM/PST background mixer. The next transition places PST bus video on air and takes the current PGM bus video off air. Selections on the two buses flip-flop at the end of the transition.

Key 1 and Key 2

The [KEY 1] and [KEY 2] buttons select the key transition mode and delegate the Key bus, Keyer, Matte, and Transition controls to Keyer 1 or Keyer 2, respectively. When you select one of these buttons, the next effects transition takes the selected key on or off air at the Program output. If you select both buttons, the Key bus and Keyer delegate to Keyer 1, but both keys are affected by the next transition.

■ The KEY ON legend lights when the keyer is on air.

■ The OVER legend lights to indicate which key layer is on top

of the other.

■ If you double-press [KEY 1] or [KEY 2], the Keyer menu appears,

allowing you to make adjustments to the key.

Section 3 — Controls & Menus

Mix and Wipe Transition Type

The [MIX] and [WIPE] buttons determine the appearance of the next effects automatic or lever arm transition—either a dissolve or a pattern transition. Only one button may be selected at a time.

Mix

The [MIX] button selects a dissolve transition. Keys dissolve on or off, and/or Preset video dissolves into and replaces Program video.

Wipe

The [WIPE] button selects wipe transition mode and delegates the Pattern and Matte sections to wipe adjustments. In wipe transition mode, a moving pattern edge wipes keys on or off and/or replaces Program bus video with Preset bus video.

■ The Pattern controls allow you to select a wipe pattern and

position its starting point. They also allow you to turn the wipe border on or off, adjust edge or border softness, and adjust edge or border softness symmetry.

3-34

■ The Matte controls allow adjustment of the wipe border

characteristics, including luminance, saturation, hue, and opacity.

■ A double press of the [WIPE] Transition button brings up the

Wipe menu, giving you access to more pattern adjustments, including more patterns, aspect, reverse, rotation, and multiplication.

Transition Controls: Cut, Auto Trans, and Lever Arm

The transition controls give you three ways to do an effects key or PGM/PST transition: an instantaneous cut, an automatic transition of a preset duration, or a manual lever arm transition.

■ The [CUT] button causes a full transition to occur instantly. The

button does not light.

■ The [AUTO TRANS] button starts an immediate transition that

extends for the period of time (in video frames) shown in the Transition rate display. The button lights for the duration of the transition. To set a new transition rate, press [M/E TRANS] in the E-MEM section, enter a number using the keypad, and press [ENTER]. The new rate appears in the Transition rate display.

Pause feature: An automatic transition in progress pauses if you press [AUTO TRANS] again and resumes if you press it a third time.

■ The LEVER ARM gives you direct manual control of the

direction and speed of a transition. When you move the lever arm off of a limit, the transition begins and exactly tracks the lever arm motion. A green arrow lights and points in the direction the lever must travel in order to finish the transition.

Transition

You can also use the three transition methods together:

■ If you press [CUT] during an auto transition or when the lever

arm is partly off the limit, the sources involved will instantly swap places; that is, the source that was transitioning on will go off and vice versa.

■ You can begin a transition with the lever arm and finish with

[AUTO TRANS], or you can begin an automatic transition and finish with the lever arm.

From the Chroma Key top menu, press [FGD SUPPRESS>] to display the Chroma Key Foreground Suppress menu shown in Figure 3-19. This menu includes adjustments to suppress (remove) background color and noise that appears in the foreground.

Foreground Suppress Menu Functions:

[FG NOISE SUPPRESS]—Sets the level of foreground noise suppression to off, low, medium, or high. This removes noise from the low chroma portions of the foreground video.

[FG COLOR SUPPRESS]—Turns foreground color suppression ON or OFF. When ON, foreground suppression removes background

color that spills onto the foreground video. This unwanted color may be the same as the background color (typically, blue or green), or it may mix with a foreground color. For example, blue spill may mix with red in the foreground, distorting the red to magenta. Foreground color suppression allows you to suppress this distortion, restoring the original foreground color.

3-46

[HUE ANGLE]—Delegates foreground suppression color detection soft knobs as explained below. Two separate colors can be independently detected and suppressed.

(FOREGROUND HUE SELECT ANGLE)—This soft knob appears when [HUE ANGLE] is set to SELECT. It selects the hue in the foreground that will be removed by the suppression circuitry. This is useful for removing background color that spills onto the foreground.

(SELECTIVITY)—Narrows or widens the range of hues selected by the Foreground Hue Angle adjustments.

(FOREGROUND HUE SUPPRESS ANGLE)—This soft knob appears when [HUE ANGLE] is set to SUPPRESS. When you adjust this soft knob, you are selecting a second color to be suppressed in the foreground. This is useful for removing variations of the background color that occur when the background color mixes with foreground colors.

Chroma Key Menus

[SUPPRESS LEVEL]—Selects foreground chroma or luminance suppression level adjustment.

(FOREGROUND LUMA SUPPRESS LEVEL)—Appears when [SUPPRESS LEVEL] is set to LUMA. Adjusts the level of

luminance suppression applied to the foreground video.

(FOREGROUND CHROMA SUPPRESS LEVEL)—Appears when [SUPPRESS LEVEL] is set to CHROMA. Adjusts the level of

chroma suppression applied to the foreground video. Normally this control should be set at about 100%.

(FRINGE CONTROL)—Controls the color of the foreground video in the fringe areas. Sometimes the fringe area is affected by the background color in such a way that the color in the fringe area is lost. The Fringe control allows you to add color back into the fringe area.

Chroma Key Edge Menu

From the Chroma Key top menu, press [KEY EDGE>] to display the Chroma Key Edge menu shown in Figure 3-20.

Chroma Key Edge Menu Functions:

[KEY SOURCE]—Selects a 4:2:2 resolution chroma key signal from the KEY bus or a 4:4:4 dual link source, such as a telecine output.

[V EDGE PROC]—When ON, this feature enables vertical processing of the chroma key and adds a frame of delay to the chroma key path. This allows you to adjust the size of the key along the top and bottom edges. The TEMPORAL selection averages two frames together to reduce noise in the edge. When OFF, all vertical edge processing is turned off, including the frame of delay. Note that the frame of delay may cause problems for some applications, such as recording on a VTR in write-after-read mode; turn edge processing OFF to turn off the delay.

[KEY SIZE]—Enables adjustment of horizontal and/or vertical key size using the (KEY SIZE) soft knob. [V EDGE PROC] must also be ON to allow vertical key sizing. When OFF, key size is unity.

3-48

(KEY SIZE)—Adjusts size of the key in the horizontal and/or vertical dimension when enabled by the [KEY SIZE] button.

[KEY SOFTNESS]—Enables softness adjustment of the horizontal and vertical key edges. When OFF, H and V softness are zero.

(KEY SOFTNESS)—Adjusts horizontal or vertical key edge softness when enabled by the [KEY SOFTNESS] button.

[KEY POSITION]—Enables adjustment of the key position.

(KEY POSITION)—Adjusts horizontal or vertical key position when enabled by the [KEY POSITION] button.

Chroma Key Menus

[EDGE CONTROL]—Selects a multiplicative or additive (mattestyle) chroma key. Multiplicative works best when the key edges are soft, such as when smoke or fog is present in the foreground. Additive works best when you are striving to preserve as much realistic detail in the key edges as possible.

Chroma Key Force Mask Menu

From the Chroma Key top menu, press [FORCE MASK>] to display the Chroma Key Force Mask menu shown in Figure 3-22. This menu controls the chroma key box mask, allowing you to apply it to the background or foreground suppression to turn off the key in selected areas.

Force Mask Menu Functions:

[BKGD MASK]—Turns background suppression mask ON or OFF. When ON, the mask forces the key off, preventing keying in the masked areas. For example, if a person in the chroma key scene has blue eyes (assuming a blue keying color), his or her eyes will need to be masked to prevent them from keying.

[FGND MASK]—Turns foreground suppression mask ON or OFF. When ON, this function prevents foreground suppression in the masked areas of the foreground. For example, a foreground object may be the same color as the color you are trying to suppress in another part of the foreground. You can prevent suppression of the object using the mask.

[INVERT MASK]—Inverts the mask. Normally, the area inside the mask box is masked. When invert is ON, the area outside the mask box is masked.

[JOYSTICK]—Turns joystick positioning of the mask ON or OFF. (SIZE)—Adjusts size of the mask shape. (ASPECT)—Adjusts aspect ratio of the mask box. (SOFTNESS)—Adjusts softness of the mask edges.
