Adding a Video Capture Device source to a scene

The Video Capture Device source allows you to add a local webcam or video device into your production. This can be used to add a live camera using a capture card or a local webcam.

 

Adding a Video Capture Device source 

To select the video source you wish to add into your scene firstly, select the scene you wish to add it into then, click the plus.png icon within the sources window.

Within the Sources drop down menu, scroll down to Video Capture Device then select Add Source.

You will now be prompted to create new or add existing. Select Create new and give your video source a name. It is good practice to give all sources a friendly name, as this helps when adding existing sources and understanding what sources are within scenes. Enter a friendly name for your Video source (e.g. Camera 1), then click OK.

The first thing you'll want to do is select the actual device you wish to capture a video source from. To do this, click on the Device drop down menu and select your device from the list. If your source is connected correctly you should see it populate the preview window. It will appear in the devices default settings.

You can activate and deactivate the video source by clicking Deactivate and Activate.

Configure Video opens up a dialog box with options for processing the video image such as Brightness, Contrast and Saturation. The second page shows options for controlling the position or focus of your video device depending on whether your device supports this.

As standard, the resolution of the video source will be set to the default for that device. You can change this by opening the Resolution/FPS Type drop down menu and changing the setting to Custom. You'll then by able to set a custom resolution in the Resolution menu underneath. As you can see in the example below, the resolution for the webcam has been changed from default to 1920 x 1080 and now fills the Preview window. You'll need to check that your device supports whichever resolution you choose.  resolution.PNG

 

You can change the Frames Per Second under the FPS drop down menu.

The Colour Space and the Colour Range allow you to determine the colour space and colour range your device will output in.

The Buffering drop down menu allows to choose between Auto-Detect, Enable and Disable. Auto-Detect will try to communicate with the device which option is most suitable, Enable is useful if you have jolty images coming through and Disable is used if you are receiving delayed signal.

Check the Flip Vertically tick box and the Apply rotation data from camera (if any) box if for some reason your image comes in the wrong way up or way around. 

 

You can choose which audio device you wish to use as an output either by selecting a default one in the Audio Output Mode drop down menu or by selecting a custom device in the Audio Device drop down. In order to access custom audio devices, tick the box Use custom audio device
