The VP4 is an advanced color corrector ideal to color match cameras. It does feature secondary corrections like a 12 vectors multimatrix and other controls only found in CCUs such as detail and coring. All channels can directly be controlled from the RCP.


  • Network: the VP4 needs an ethernet connection to the RCP, and a PoE Switch is necessary to power the RCP or an external 12V power supply should be used.

  • SDI Cables: 9x 3G-SDI cables with DIN 1.0/2.3 connectors are required to connect the 4 channels and reference.

  • Computer: required to access the web configuration of the VP4 and RCP.



step 1 Network setup: connect the RCP, the VP4 LAN port and your computer to the switch. For software update, connect the switch to your internet access.


step 2 Video connection

  • Connectors: DIN 1.0/2.3
  • Video: 720p/1080i HD-SDI or 1080p 3G-SDI in 50/59/60
  • Reference: compatible with Black Burst and Tri-Level

step 3 Turn VP4 ON

Long press on the power button will turn VP4 on/off.

The boot status is displayed on the LED on the front panel.

  • The first LED turns green when the unit is powered.
  • The second LED turns green when the unit is booted and operational.


The VP4 is configured and operated from RCP.

step 1 RCP configuration

To access the RCP, please refer to Access cyanview devices

  1. If DHCP is available, point your web browser to http://cy-rcp-x-y.local/. x-y is the serial number of the RCP. This address is displayed during boot and by pressing the MENU button.

  2. Without DHCP, use the IP address directly: http://10.192.x.y. Make sure your computer has an IP set in the range (i.e. ip mask Check how to set IP addresses on your computer.

The following diagram shows a static configuration for a RCP with serial CY-RCP-18-34.


You should get access to the following page.


Verify that the VP4 appears at the bottom of the page.

step 2 Add video channels

In the configuration, video processors are added as post-processing options to cameras. In this quick start guide, we only want to control the video processor and so we will use a camera of type Not Controlled.

Add a Not controlled camera: click the + button on the top right of the camera section. New camera properties appear in the right sidebar. Fill-in these fields:

  • Number: camera number displayed on the RCP
  • Name: camera name displayed on the RCP
  • Camera Head Model: Select Not Controlled camera from the list. An interface section will appear.
  • Interface Port: Add the first VP4 video channel in the Video Processor section.

Repeat for the other channels

Genlock settings#

Video genlock selection isn't available yet from the configuration panel. In the meantime, the development interface does provide the possibility to configure it although it's not pretty and not the most convenient.

  • Go to http://10.192.x.y/dev/app.html
  • Click on the VP4 external block to highlight it green
  • On the right side, the VP4 properties will be shown. You might have to zoom the window out if it is clipped or not shown at all.
  • Specify the genlock parameters in the corresponding text field of this table.

The genlock input parameters format is:

[freerun|genlock] [horizontal pixels] [vertical lines]


genlock 0 0

The 0 0 parameters are the horizontal pixels and vertical lines of phase adjustment.


Operations are performed from the RCP.

Basic RCP Commands

  • The top row of buttons selects the top menu of the main LCD
  • The bottom row selects the submenus which are the second row of labels on the LCD
  • The paint menu can be cycled between OFF -> PAINT 1 -> PAINT 2
  • The Menu button shows some status pages including the IP Address received by DHCP
  • The left/right arrows on the bottom of the page cycle between cameras
