6.2. Transition: CUT/ AUTO/ T-BAR

This video switcher offers three transition control types: CUT, AUTO and T-Bar.
CUT performs a quick transition between Preview and Program, bypassing any selected transition effects
like WIPE, MIX, or DIP.

AUTO performs a smooth transition between Preview and Program, allowing to adjust the transition
speed using the speed button. WIPE, DIP, and MIX transition effects are available.

T-BAR performs manual transition, which is similar flexible to AUTO transition. Users can control the
transition speed by the movement of the T-Bar lever.

7. TRANSITION EFFECT
The video switcher provides various transition effects and settings for choice.

7.1. WIPE
Outside of menu mode, simply press the EFFECT button on the panel to summon a quick menu in the
display's left corner. Select the WIPE option to swiftly apply the wipe transition effect. For added
customization, adjust the WIPE style and edge softness to your preference. When using the AUTO
transition, choose between Normal, Invert, and Flip-Flop directions.

7.2. DIP
Outside of menu mode, simply press the EFFECT button on the panel to summon a quick menu in the
display's left corner. Select the DIP option to promptly apply the dip transition effect. For added

speed setting will be automatically saved for future use. Higher values correspond to slower transition
speeds, with a wide range of options from 0.1 seconds to 8.0 seconds available to cater to diverse
creative requirements.

8. UPSTREAM KEY
Upstream keys are intrinsically integrated into the transition process. When switching from Preview to
Program, any upstream key elements will seamlessly transition alongside the main video content.

8.1. Chroma key

Chroma key is a visual effects technique that combines (overlay) two images or video streams based on
color hues (chroma range). It's commonly used to remove a background from the subject of a photo or

9
SHARK
Shark S6 S6 HDMI/SDI VIDEOSWITCHER
VIDEO SWITCHER

video, particularly in newscasting, movies, and video games.

Access the chroma key menu to select the desired key source from SDI1, SDI2, SDI3, SDI4, HDMI5,
HDMI6, Color Bar, or Black video sources. In Fetch XY mode, utilize the 3D joystick to pinpoint the color
you want to remove. Fine-tune the chroma key's similarity, smoothness, spill, and opacity to achieve the
desired effect. Additionally, configure the chroma key's effect parameters, including Brightness, Contrast,
Saturation, and Mask, directly from the menu page.

10
SHARK

9. DOWNSTREAM KEY
Downstream keys (DSKs) are the final layers of keying, overlaying all video switched to the main program
output. They function independently of the selected background, ensuring that any content placed on a
12
SHARK
Shark S6 S6 HDMI/SDI VIDEOSWITCHER

DSK remains on the screen regardless of transition changes. DSKs are ideal for incorporating animated
bugs or logos into the program output.

9.1. TIE
As we know the DSK is usually used for logo or title overlay into the program out directly, but if users want
to make downstream key active in transition when use AUTO or T-Bar, can just turn on the TIE option from
the menu.

9.2. DSK

DSK settings, including source (Key Source), clip, gain, and mask (Mask Enable, Mask Left, Mask Top,
Mask Right, Mask Bottom), can be configured from the menu. Select the PGM button in DSK status to
enable the KEY on PGM. The key will not be affected when switching between PVW and PGM. Choose
from the following options to determine whether the DSK key applies to PGM or PVW:

14. PTZ CONTROL

The video switcher has a feature that control PTZ cameras through LAN port or serial port. Utilize the
joystick and buttons to pan, tilt, or zoom individual cameras. Protocols supports: VISCA, VISCA over IP,
Pelco D/P, and Onvif..

For LAN port connection, ensure DHCP is enabled, and so we put them on the same LAN. Search the
camera through VISCA-IP or ONVIF from menu, and then we can add the camera we searched into a
camera ID. If the working environment doesn’t have DHCP for network, we can change the IP address of
the switcher from menu to set them in a same LAN, so that the switcher can search the camera
successfully.

27
SHARK
Shark S6 S6 HDMI/SDI VIDEOSWITCHER
VIDEO SWITCHER

Access the PTZ menu using the joystick knob, search for the camera, select the camera to be connected,
and customize the camera ID if desired. And select the corresponding protocol from the menu that there
are VISCA-IP and Onvif available for network connection. Last, toggle the connection switch to establish
the connection.

There are 3 ways we can call the camera we want to control:

1. Set the call option to Follow PGM, which means the controlled camera is same to the selected PGM
channels from Camera 1-6. For example, when the PGM is selected the Camera 2 (IN 2), then the
Camera 2 is under control.

2. Set the call option to Follow PVW, which means the controlled camera is same to the selected PGM
channels from Camera 1-6. For example, when the PVW is selected the Camera 2 (IN 2), then the
Camera 2 is under control.

3. If set the call option to Camera ID, then we can set the ID option from camera 1-6.

For connection through serial port, select the corresponding protocols from VISCA, PELCO-D, PELCO-P,
and camera ID, and baud rate, serial port type settings. Subsequently, enable the connection switch to
establish the connection.

Once the camera is connected, employ the 3D joystick to control camera movement. The zoom function
can be operated using the zoom + or zoom - buttons on the panel. We also can adjust the Pan/Tilt/Zoom
speed in the PTZ menu as needed.
