The AJA control panel may look different and can offer other variations in function depending on the driver version and hardware you are using. Always use the latest driver release.

Control

Here you choose the "Default Output" you'd like to have when just:out is not started. Also configure the "Playback Timing":

Choose "Free Run" if you do not have a reference signal attached to the AJA device
Choose "Ref In" if you have a reference signal attached to the AJA device. This implies that you don't turn on the downstream keyer for the switch-to-live functionality
Choose "Video In" if you turn on the downstream keyer to enable the switch-to-live functionality. Using the DSK, remove any signal which is attached at the Ref. In.

Format

Under the "Format" tab you select the primary format your playout will use. This is usually the same format you select in the preferences of just:out. Although just:out will change the format automatically, we recommend to set the primary and – if available – the secondary format here. Defining a secondary format allows you to get two different output formats of the same playout. Also set the "RGB Range" to "SMPTE".

Conversion

Set "Pause on" to "Full Frame". When using an RGBA mode (= graphics enabled), configure the "YUV-RGB Conversion" settings like shown. It is likely that you will use "Rec 601" when working in SD and "Rec 905" when working in HD.
