GPICommander is a device that you connect in USB to your computer and that has 8 outputs and 24 inputs.
Connecting the GPICommander box
You will need to:
- Connect the GPICommander device to the computer where OnTheAir Video is running.
- Connect the GPICommander's inputs to your device (it can be a production switcher GPI/tally output or a simple push button box) using the DB25 connector. Check the User manual for instructions on how to connect it.
With OnTheAir Video you will mainly use the inputs. These 24 inputs are available through a DB25 connector, where basically and very briefly, an action will be triggered in OnTheAir Video when any of the first 24 pins is connected to the "ground" (on pin 25).
Use the direct integration in OnTheAir Video (Express)
Open the the OnTheAir Video preferences, and select the GPICommander to be used in the top left drop down menu. You can connect multiple GPICommanders to one computer, but only use one in OnTheAir Video. They will be listed with their serial numbers.
Once you have selected the GPICommander to use, select the type of behaviour that you want in the "Usage" drop down menu:
You can decide for 2 types of usage:
- As Remote Controller (more for generic uses)
- As Video Switcher (specifically when used with a production switcher)
GPICommander "As Remote Controller"
When you select to use GPICommander "As Remote Controller", you will be able to set 2 type of things:
- Input Actions: set the action to be performed when a given GPI input is triggered
- Tally Outputs: set the output to put on on depending on the status of OnTheAir Video
You will see there a list of different actions that can be performed. For example the "Play Selected Clip" action when triggered will start playing the selected clip in the "Front" playlist. You must then define which input should be monitored. For that clip on the popup menu next to the action:
Select for example "In 1". In that case, as soon as the input 1 of the selected GPICommander turns to on, the selected clip in the from playlist will start playing.
You can configure all actions like that. They are quite "self explanatory". The only things to note are:
- if no clip is selected, then the action will be done on the first clip in the playlist
- the "Space Bar" action will mimic the behaviour done when you use the "Space bar" on your computer. This can be quite useful for cue mode, etc...
There are 2 kind of status that can be monitored:
- Playing: when OnTheAir Video is playing a clip, the selected output will be put to on
- Paused/Cue: When OnTheAir Video is paused or cued, the selected output will be put to on
GPICommander "As Video Switcher"
When you select to use GPICommander "As Video Switcher", the behaviours will be different, and is mainly used when GPICommander is connected to a Production Video Switcher. It is not mandatory, and you can use the "As Remote Controller" mode when connected to a Production Video Switcher, but basically the behaviours here will be identical to the ones when using an "ATEM Switcher".
You will have 2 settings:
- OnTheAir Video Input
- Cue next clip when "OnTheAir Video Input" goes off
The behaviour will be as follows:
- as soon as OnTheAir Video sees that the monitored input goes to on (it is then in use on your production switcher), it will start playing the selected (or cued) clip in the front playlist
- then when the monitored input goes back to off (it is not in used anymore on the production switcher), and if the "Cue next clip when OnTheAir Video Input is deselected" option is enabled, we will automatically cue the next clip.
