  • Page 71: Dpm Capabilities (Fixed And Pooled)

    There are four steps in configuring the video path: Aux buses are assigned to DPMs using the DPM Map Aux Buses Menu Return input connections are configured using the DPM Map Inputs Menu The mapping of a return connection to a crosspoint is done using the Configuration/Map Inputs Menu The video delay is set using the DPM Setup Menu.
  • Page 72 Section 2 — Startup & Configuration Both In systems with multiple DPM channels, it is desirable to have a predictable relationship between aux buses and DPM channels (e.g., aux bus 1 feeding DPM channel 1, aux bus feeding channel 2, etc.) and to have a particular switcher crosspoint button always select the same DPM channel return input.
  • Page 73 The Aux Bus button selection made on the switcher control panel is always a logical aux bus; however, unless Kaleidoscope is connected, Logical Aux Bus 1 always corresponds to Physical Aux Bus 1, etc. (The current mapping of physical-to-logical DPM channels is displayed in the DPM Map Inputs Menu.) It should be noted that the switcher supports only one pooled device.
  • Page 74 Section 2 — Startup & Configuration For a particular studio session, three Kaleidoscope channels could be acquired from the pool in the order D, E, A, which would be logical channels 1, 2, 3. This mapping information is passed from the DPM to the switcher via the control connection.

  • Page 109: Switcher Concepts

    Switcher Concepts This section describes a few basic concepts that you should know before you operate your switcher. You might be tempted to skip over this section, especially if you are an experienced switcher operator. Nevertheless, we suggest that you to browse it anyway because it explains operating concepts that will help you more fully understand how the switcher works.
  • Page 110: Section 3 - Switcher Concepts

    Section 3 — Switcher Concepts Clear Working Buffer The Current Working Buffer (CWB) is an area of system memory that stores the current switcher state. That is, it tracks the settings of switch and variable control functions on the control panel, as well as those of many switch and control functions set in the menus.
  • Page 111: Cwb Modes Of Operation

    CWB Modes of Operation With Version 5.0 and later software, there are four modes of operation for the 1. Single press of the Current Working Buffer except Keyers. This clears the CWB to User-Defined Defaults for all enabled levels, but leaves the key memory portion of the CWB unaffected.
  • Page 112: Auto Delegation

    Section 3 — Switcher Concepts Auto Delegation Some of the switcher subpanels are delegated to other subpanels under conditional control of the operator or system. This feature is called “auto delegation.” The effect of auto delegation is that pressing a button on one subpanel may activate the related controls on another subpanel.
  • Page 113: Crosspoint Bus

    Crosspoint Bus A crosspoint bus consists of a group of switches called crosspoints, each with a different video or key input. The row of switches has a common output called a bus. The various crosspoint buses on the switcher’s control panel make up the Source Select Subpanel (the large matrix of buttons that occupies the left 1/3 of the control panel), which is used for connecting the video and key input buses to the crosspoint output...
  • Page 114: Transitions

    Section 3 — Switcher Concepts Transitions A transition is a change from one video picture to another. The switcher provides three methods for making video transitions: Cut Transition A cut is an instantaneous switch from one picture to another. A background cut, for example, switches the on-air Program output instantly from the picture selected on the Program bus to the picture selected on the Preset bus.

    Section 3 — Switcher Concepts Wipe Transition A wipe is a transition from one picture to another in which a shaped edge moves across the screen revealing the new picture (see Background picture as it wipes on the new Preset Background picture.
  • Page 117: Keys

    Keys Keys 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.
  • Page 118: Luminance Key

    Section 3 — Switcher Concepts Luminance Key A luminance key, shown in information in one picture, called the key source to cut a hole in another picture, called the background. A third picture, called the fill, is inserted into the hole to fill it. A clip control allows the operator to set the level of key source brightness that will cut the hole so that any part of the picture that is lower in brightness than the clip setting is ignored and will not cut the hole.
  • Page 119 Keys 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.
  • Page 120: Linear Key

    Section 3 — Switcher Concepts Linear Key A linear key is similar to a luminance key except that the gain of the key is set to a value of one (also called “unity”) so that the edges of anti-aliased key sources are faithfully reproduced. 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.
  • Page 121: Shaped And Unshaped Video

    Shaped and Unshaped Video Shaped and Unshaped Video Shaping and unshaping are generally involved only in keying and compositing situations. Whenever a key is performed, there are always three signals: the key source, the key fill (fill video), and the background video. The key signal cuts a hole in the background, into which the fill video is inserted.
  • Page 122: Input Shaped And Unshaped Video

    Section 3 — Switcher Concepts Input Shaped and Unshaped Video Video coming into a switcher may or may not already be shaped, depending upon its source. The Configuration Menu has a selection for you to define whether the source video for each video input is shaped or unshaped.
  • Page 123: Super Black

    Super Black Super Black Super Black is a video level that is lower than the usual black level (7.5 IRE in NTSC; 0 IRE in PAL and Component video). It is inserted into the background of a video signal to improve the contrast for luminance self keying.
  • Page 124: Chroma Key

    Section 3 — Switcher Concepts Chroma Key A chroma key is a key in which a particular color that you select in 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.
  • Page 125 Chroma Key The 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”...
  • Page 126: Coring

    Section 3 — Switcher Concepts Coring Coring is a video noise-reducing operation in which pixels below a predetermined luminance threshold are replaced by “clean” black pixels. During keying, the black eliminates any noise surrounding the fill video that might otherwise add to the background, causing noisy key edges.
  • Page 127: Layering

    Layering Layering Lamina™ Video Compositing is a feature that enables up to four video layers to be composited in a single mix/effects system. The composite image can then be used as a key source or a background in another mix/effects system or the downstream keyer.
  • Page 128: E-Mem Effects Memory

    Section 3 — Switcher Concepts E-MEM Effects Memory The E-MEM Effects Memory system provides a way of storing switcher effects for later use. With E-MEM you can set up an effect with the control panel and “learn” a snapshot of it into memory. Later, you can recall that effect with the press of a button.

    Keyframing / Timelines / Effects Editing Keyframing / Timelines / Effects Editing Switchers are able to store more than one switcher state (a “keyframe”) on each enabled level in a single E-MEM register. A series of keyframes in an E-MEM register is called a keyframe effect. Effects animation can be accomplished by building and running keyframe effects.

  • Page 241: Appendix B - Keyframe Facts

    Appendix B — Keyframe Facts Keyframe Timelines Master Timeline The Master Timeline is a tool for developing a consistent set of rules and operations for editing effects and synchronizing events across multiple independent timelines. The Master Timeline is a single timeline representation of the two-dimensional view of multiple E-MEM level timelines.
  • Page 242 Appendix B — Keyframe Facts If the keyframes occur at different points in time on the various enabled E-MEM levels, it is possible that the keyframe durations on the Master Timeline will not match any of the individual E-MEM keyframe durations. The Master Timeline provides consistency so that when editing across multiple E-MEM levels, the relative keyframe positioning is maintained.
  • Page 243: Enables And Delegates

    Enables and Delegates The E-MEM system is divided into functional levels. Some or all of the levels contribute to the overall look of a given effect. Those levels must run in sync with each other in order for the effect to look right.
  • Page 244 Appendix B — Keyframe Facts When delegated; all other enabled levels are enabled but not delegated. This feature allows you to edit a delegated timeline while viewing its relationship to timelines not being edited. When a level is not enabled, its timeline disappears, and its keyframes are removed from the master timeline.
  • Page 245: Keyframe Path Control

    Keyframe Path Control Tension, Continuity, and Bias Controls The path that an effect takes between keyframes may be adjusted through the Menu. CURVE three parameters of the vector. These are labeled: Tension, Continuity, and Bias. The adjustment of these controls can affect the keyframe path in various ways.
  • Page 246: Path Vectors

    Appendix B — Keyframe Facts Path Vectors With respect to the path between keyframes, each keyframe is made up of three vector parameters as shown below. The soft knob controls act on these vector parameters to adjust the path into (entry) and out of (exit) the keyframe. The path through KF2 is parallel with an imaginary line drawn between KF1 and KF2.
  • Page 247: Tension Control

    Tension Control In the example below, the keyframes are at right angles so the control operates on a 45° line drawn through the TENSION keyframe. This line is referred to as the Tension Vector and is parallel to a line drawn between adjacent keyframes (see illustration).
  • Page 248 Appendix B — Keyframe Facts In Example 2, the Tension vector is shortened to non-existence through KF2. The path enters and leaves the middle keyframe in a straight line as it takes on an S-Linear motion; decelerating as it enters the middle keyframe and accelerating as it leaves.
  • Page 249 Keyframe Path Control In Example 3, the control has been set to -1.00. This TENSION produces an effect of lengthening the Tension vector, causing the path through the middle keyframe to be longer and broader. The longer path will appear to make the image speed up through KF2 as it travels from KF1 to KF3.
  • Page 250: Continuity Control

    Appendix B — Keyframe Facts Continuity Control The continuity adjustment determines the angle of the path into and out of the keyframe. It is represented by vectors at 90 degrees to each as shown in Example 4. Continuity = 0.0 The unmodified path shown above is identical to the unmodified path of the other controls.
  • Page 251 Keyframe Path Control With continuity set to 1.00, the entry path through the keyframe is pulled to point at the following keyframe or exit path. The effect of 1.00 continuity is that of motion dropping into and then out of the keyframe, similar to a bouncing ball (see Example 5).
  • Page 252 Appendix B — Keyframe Facts With continuity set to -1.00, the paths between the keyframes become straight lines, accelerating through the keyframe (see Example 6). B-12 Example 6 +1.0 -1.0 Continuity = -1.00 +1.0 -1.0...
  • Page 253: Bias Control

    Bias Control control determines whether the path will be “pulled” BIAS towards the previous or the following keyframe. With extreme settings, all of the biasing will occur either before or after KF2. With bias set to 0, the curve through the keyframe is gentle as shown in Example 7 below.
  • Page 254 Appendix B — Keyframe Facts With the bias set to 1.00, the path is pulled towards the previous keyframe. Entrance and exit to the keyframe are on a straight line from the previous keyframe (see Example 8), and the path of the effect travels completely through KF2 before turning towards KF3.

  • Page 257: Appendix C - Super Black

    Appendix C — Super Black Definition of Super Black Super Black is a video signal that is lower than the usual black level (7.5 IRE in NTSC; 0 IRE in PAL and Component video). The actual level of the signal below black varies from situation to situation and is often limited by the device that is used to record the signal.
  • Page 258: Usage

    Appendix C — Super Black Usage A typical use of super black is when a prerecorded element such as a flying logo is to be keyed in at the opening of a show. The flying logo is keyed over super black and recorded on tape. (The VTR must be adjusted to record the super black level and to reproduce it during playback).
  • Page 259: Generating Super Black

    Drawbacks of using a Super Black Output: The reconstruction of the video and key is rarely perfect, and quite a bit of control adjustment is necessary to produce the best results. Keying from Super Black produces a hard-edged key only. No shadows, softness, or transparency can be used.
  • Page 260: First Method

    Appendix C — Super Black In the Model 3000, 4000, and 2200 Switchers, there are two ways to produce Super Black: First Method This is the traditional “Key over a Super Black Matte” Mode. With this method, you use one of the background matte generators as a Super Black generator.

    Each output module has four channels that are arranged with the video and key on adjacent channels. For example, the Program Output module is arranged as follows: Channel 3 -> Program Video Channel 4 -> Program Key The Configuration/Outputs menu allows you to turn Super Black on for a particular output.
