Positioner

The KM-H3000 has a joystick positioner for positioning wipes, patterns, washes, and DVE effects. The KM-H2500 does not have a positioner.

Selecting Colors

Functions such as mattes, and Panel Glow have options for adjusting the appearance of a selected color. Individual adjustments for colors are:

• Luminance

•Hue

• Saturation

Luminance

Luminance affects the brightness of the video signal. Increasing luminance gives a brighter color while decreasing luminance gives a darker color.

Hue

Hue controls the shade of color (red, yellow, green, blue, etc.).

Saturation

Saturation affects the vividness of a color. Increasing saturation produces a more vivid color while decreasing saturation produces a less vivid color. Fully decreasing the saturation produces gray.

Configuration

This chapter describes how to configure your switcher to meet your requirements. Setup and switcher personality options are discussed.

Reference Type

The switcher supports both external and internal reference types.

To set the reference type:

1. If you are using an external reference signal, ensure that it is connected to the REF IN input.

2. Press MENU.

• 1080i

4. Press the Format knob to save the selection.

Note:

• If you set your switcher to an interlaced video format and an external reference source, ensure that you use an interlaced external reference signal.

There are separate North American and European versions of the switcher.

North American Video Formats

North American switchers support the following video formats:

• 480i (4:3 and 16:9) at 59.94Hz

• 720p at 50 or 59.94Hz

• 1080i at 50 or 59.94Hz

Note:

• To save space in the menu, 59.94Hz is displayed as 60Hz.

Format Conversion and Frame Sync

The switcher has four input format converter / frame synchronizer (FCFS) channels that can be used for the following:

• Converting incoming video to the current switcher video format. The format converters can convert input video from many formats to the current switcher video format.

• Correcting mis-timed or drifting input signals in any of the supported video formats. The frame synchronizers can not completely correct badly formatted video streams, mis-timed switches, signal dropouts, or similar issues.

Understanding Aspect Ratio Conversion

16:94:3

4:316:9

16:94:3

4:316:9

Converting between video formats often requires converting between aspect ratios. Your switcher supports the following aspect ratio conversion methods:

• Full — The video signal is scaled disproportionately to fill the display of the new aspect ratio. Aspect distortion occurs as the image is stretched/compressed to fit in the new aspect ratio.

Figure 1 Full Aspect Ratio Conversion

• Zoom — The central portion of the video signal is zoomed to fill the display of the new video format. No aspect distortion is introduced but the edges of the video signal may be cropped.

• PllrBx — Black bars are added to the right and left of a 4:3 image to display correctly in a 16:9 video format.

16:94:3

Figure 4 Pillar Box Aspect Ratio Conversion

Assigning FCFS Channels

FCFS channels are assigned to either specific inputs or bus-pairs. Each bus-pair requires two FCFS channels. The bus pairs are as follows:

• PGM – Preset buses

• Key 1 Video – Key 1 Alpha buses

• Key 2 Video – Key 2 Alpha buses

• Key 3 Video – Key 3 Alpha buses

• Aux 1 – not paired

• Aux 2 – not paired

• Aux 3 – not paired

FCFS channels maintain separate settings for different switcher video formats. This lets you change between switcher video formats without losing FCFS channel configurations.

Note:

• Using an FCFS channel creates a one frame delay for the input video being processed.

Input BNC Configuration

Many video sources have an associated video source that contains alpha (transparency) information. You must configure the switcher to use the correct alpha source. Once you associate a video and alpha source, they are linked and used for Auto-Select keying.

Alpha sources are designated as shaped or linear (unshaped). Shaped sources convert partial transparency to either fully transparent or fully opaque, giving the video signal well-defined edges.

Linear (unshaped) sources use the full range of transparency in the alpha channel to give smooth transitions between transparent and opaque areas. Use linear if you are unsure which setting to use.

6. If you are using standard definition sources, use the SD ASP knob to select the aspect ratio of the video signal. You can choose from the following:

•16:9

•4:3
