When using the DSK based built-in switch-to-live function in v2.8 or lower, closed captions are NOT passed through the AJA hardware AND closed captions can NOT be added to the SDI output. However, when closed captioning is activated for a specific channel, just:out will write CC data to the outgoing signal. In other words it is not possible to add CC data while using the built-in switch-to-live function. In this situation, the traditional setup with an external CC capable mixer should be used.

Using the non DSK based switch-to-live function, supported CC data will be passed through.

Up to version 2.8, CC is only supported when using an AJA device.

With v3 or higher, we support devices from AJA and BMD to play out and passthrough CC data from a movie or a live signal. Please consult the admin handbook for more information.
