Chyron Alpha channel is not being mixed in DSK

Chyron Alpha channel is not being mixed in the Black Magic Design Broadcast Panel DSK.  It is mapped along with the normal channel.  Anybody have an idea on a fix?

Turn pre-multiplied on or off

Turn pre-multiplied on or off depending on whether your Chyron is set to produce a pre-multiplied output.

My guess is it is not outputing pre-multiplied, and hence you'll need to switch that off and use Clip and Gain to tune the output.

We figured the problem out.

We figured the problem out.  We needed to assign the Apha Channel to the DSK so that both the Key and Alpha where mixed.
