4-Input HDMI Switcher with USB Output

2
The Elvid VSW-4H-USB Broadcast Video Switcher is a powerful yet compact unit that puts advanced switching and professional video effects
at your ngertips. Great for livestreaming and broadcast applications, this switcher will boost the production value of any multicamera
presentation, concert, panel discussion, or interview.
The VSW-4H-USB features four HDMI inputs that support up to full HD 1080p video, and a USB input to upload your graphics, logos, and
artwork to the switcher’s media library. Two congurable mic/stereo line inputs can add live narration or music to the production. Perform
creative transitions, mix audio, and use the pattern generator and extensive pattern library to set up downstream and upstream keyers, all
from the intuitive control panel. Flexible output options let you place a multiview screen in your control room or at your workstation, and a
second monitor that displays the live broadcast or any one of the incoming video sources. The switcher’s built-in encoder automatically scales
and deinterlaces incoming video signals and outputs video to user-selected resolutions up to 1080p. The live broadcast can be outputted to a
broadcast device, projector, or recorder, and simultaneously streamed to the internet via the USB output.
THANK YOU FOR CHOOSING ELVID.

KEY (PVW): Displays the chroma effect only in the Preview window.
ON AIR (PGM): Displays the chroma effect only in the Program
window.
KEY & ON AIR: Displays the chroma effect in both windows.
To quickly change the output status, use the CHROMA and ON AIR
buttons on the control panel.
Invert
Selecting the Invert Key menu option turns it on. When turned on, it
swaps the key and ll sources.
MASK (LUMA & CHROMA KEY)
Luma and Chroma Key menus feature mask adjustment menus.
When the Mask Enable menu is on, an adjustable rectangle can be
congured to crop out any portions of the luma/chroma key effect

inverts the key and ll sources.
Clip and Gain
Clip: Clip adjusts the Key source’s threshold. Raise the key clip
percentage to increase the level at which the key cuts a hole.
Decrease the percentage to reveal more of the background. If the
screen is black, the clip is too low. If the key is not visible, the clip is
too high.
Gain: In luma key, key gain adjusts the transparency of the key’s light
or white areas. In chroma key, key gain adjusts the transparency of
areas that are similar to the key color. Apply more Key Gain if the
light areas become too transparent.
LOGO
The logo feature is another downstream key effect that lets you
