What is a Channel?

A Channel is a virtual representation of a single input of your Video Capture Device. Depending on the number of Capture Devices and the number of inputs each device offers, you may configure one or multiple Channels.

Adding a Channel

1. Open just:in.
2. Open the Connections Window by selecting the menu command Channel → Connections or use the shortcut command + K. You can also click on the Connections Window button in the center while hovering above a Channel View.
   
   
   
3. In the lower area enter the IP Address and the Port of the desired Mac- or Linux-Channel. Press the Add button afterwards.
   
   
   

4. The Channel will be added to the Channel List. The actual Channel Name is only available once the Channel has been connected to. Before connecting to a Channel a question mark will be shown.
   
   

   When adding multiple Channels they usually have consecutive Port numbers (50000, 50001, 50002 and so on). The just:in Connections Window automatically increases the Port number after each press of the Add button.

5. You may now connect to the Channel by following the steps below.

Connecting to a Channel

1. Open just:in.

2. Open the Connections Window by selecting the menu command Channel → Connections or use the shortcut command + K. You can also click on the Connections Window button in the center while hovering above a Channel View.
   

   If there are multiple Channel Views select the Channel View first and then press the Connections Window button to connect a Channel to this particular Channel View. You can still reorder the Channel Views later by drag & drop, as described in the chapter Managing Channel Views.

   

3. The Connections Window appears. Press the Connect button of the desired Channel to connect to it.
   
   
   
4. Repeat steps 2 and 3 for all Channels you would like to control with this User Interface.
5. The Channel Preview should now be shown and you are ready to use the Channel.
   

Problems when connecting to a Channel

If you get this warning double check your IP-Address and Port number as well as the configuration of just:in Engine and the network. Also read the troubleshooting info at the end of this chapter.

Disconnecting from a Channel

1. Open just:in.
2. Optional: if there are multiple Channel Views, first select the View you want the Channel to be disconnected from. 
   
   
   
3. Select the menu command Channel → Disconnect or use the shortcut command + shift + D.
   
4. You may now connect another Channel to the View.
   

Removing a Channel in the Connections Window

1. Open just:in.
2. Open the Connections Window by selecting the menu command Channel → Connections or use the shortcut command + K.
   
3. Click on the X button of the appropriate Channel to remove it from the Channel Manager. This cannot be undone.
   

Pending Channel Connections in the Connections Window

When a Channel connection cannot yet be established or has been interrupted, the Connections Window will display Connecting… on the particular Channels. Wait for the Channels to be online or read the troubleshooting information below.

Troubleshooting

Connecting to a Channel may not immediately work when just:in Engine is not properly configured or reachable. There may be other reasons, the most common ones are listed here.

Removing "Ghost Channels" from the Connections Window

The Channel List in the Connections Window may display Channels which cannot be removed anymore. If such a ghost Channel appears, follow those steps:

1. Dismiss any error message.
2. Split the Channel View.
3. Switch to another free Channel View.
4. Join the Channel View.
5. Open the Connections Window.
6. Delete the appropriate Channel.

Wrong IP Address and/or Port

Consult your system administrator for further information. If you have configured the network by yourself, verify that everything is set up correctly.

just:in Engine isn't running and/or Channels aren't enabled in just:in Engine

Verify that just:in Engine has been started and that the desired Channels are enabled. You can see if a Channel is enabled by looking at the Channel List in the just:in Engine Preferences. Also verify that the particular Channels you want to connect to are not occupied by another just:in User Interface client.

just:in Engine not reachable

Verify that the network connection has been set up properly. Consult your system administrator for further information. If you have configured the network by yourself, verify that everything is set up correctly.

Unstable Video Preview and/or Connection Losses

There may be network connection issues. Use a stable and fast network connection between the just:in User Interface and just:in Engine. Do not use a WiFi connection.
