How to set up Mercury Transmit in SpeedGrade CC

Mercury Transmit allows you to use an external broadcast monitor with SpeedGrade. This gives you reference quality image display so you can accurately view. Currently you can use Mercury Transmit in SpeedGrade with third-party video IO cards from AJA, Matrox, and Bluefish. In this post, we’ll show you how to set up Mercury Transmit using an AJA Kona 3G as an example. 

1. Install drivers
To start the setup, download and install the AJA Kona 3G driver and the Adobe plugin installer from AJA support website.

Note: Matrox offers the driver and the Adobe plugin in a single installer. You can also download the Bluefish444 driver and installer for Windows.

If you already have an older AJA/Adobe plugin installed we recommend you uninstall it and replace it with the latest version. Please do that in this order:

  1. Uninstall the old AJA beta plugin
  2. Install SG CC 7.0
  3. Install the new AJA beta plugin

After installation has completed, AJA mercury transmit plugin should be in following location:

  • Windows: [AdobeProgramFiles]CommonPlug-ins7.0MediaCore
  • Mac OS: [AdobeCommon]/Common/Plug-ins/7.0/MediaCore

This location is shared with other Adobe applications (After Effects, Premiere Pro etc.). Once the plugin is installed successfully it should work with all of these applications and no re-installation is required.

Note: It is mandatory for some of the installers (i.e. Matrox) that Premiere Pro is already installed. For a SpeedGrade-Matrox setup we recommend that you install Premiere Pro CC before installing SpeedGrade CC:

  1. Uninstall old Matrox drivers/plugins
  2. Install PR CC 7.0
  3. Install SG CC 7.0
  4. Install new Matrox drivers/plugin

2. Enable Mercury Transmit in Speedgrade
To enable Mercury Transmit in Speedgrade, launch SpeedGrade and then open Settings > Display.

In the Mercury Transmit settings choose AJA Kona device, set the output resolution (720p,1080p, 2K) and enable Mercury Transmit.

After enabling Mercury the monitor image should be visible on the external display. The primary display should show just the SpeedGrade UI, without the monitor.

How to change Mercury Transmit playback settings
To change playback settings click on Setup in the Mercury Transmit preferences (Settings > Display > Mercury Transmit).  You can set the AJA plugin to either Match Sequence or Match Control Panel

When Match Sequence is selected, AJA plugin will use the SpeedGrade base frame rate for playback (Settings > Playback > Base Frame Rate). For example, if the base frame rate was set to 24FPS in SpeedGrade, AJA will automatically use the same frame rate for playback.

If you use Match Control Panel, the AJA plugin will use settings from the AJA control panel.


  • On Windows you can still use native SpeedGrade support for NVIDIA Quadro graphics cards to provide external monitoring
  • Even if you don’t use an external monitory, you can always use dual display setups with conventional monitors in SpeedGrade. This solution places the monitor into a second display, with the color controls and the rest of the SpeedGrade UI on the primary monitor.

    Is there any info about Blackmagic support coming in the near future?

      Hi Bastiaan,

      This has taken longer than we would have hoped, but I can report that we are working on this now and expect to have an update with Blackmagic support sometime in the new year.
