External video overlay
In this article:
Overview
Wincaps supports the ability to display the picture from an external video source in the Video window. In order to do this, the host PC must contain a suitable graphics card capable of video overlay using a standard video input (i.e. VIVO).
Wincaps supports the BlackMagic Decklink Mini Recorder card (see below for configuration instructions) running with drivers 11.1 or below. Other similar cards may work with Wincaps but these have not been tested.
If the PC contains a compatible card, Wincaps Q4 will detect it automatically and the option will be available whenever you go to open a video.
The procedure for using the overlay card is as follows:
-
Connect a suitable external video signal to the input of the overlay card.
-
In Wincaps Q4/Q-Live, open a file and choose a story (Q-Live).
-
Click the video play button or press the 5 key on the numeric keypad to start the media. The Choose Media Type dialog is displayed:
-
Select Video Overlay from the drop-down list and click OK.
-
The external picture is displayed in the in the Video window after a short pause.
You can stop the external video input by right-clicking in the Video window and choosing Close from the pop-up menu.
Note that the control of external video sources is not part of Q4; the keyboard video playback controls are for digital media file only.
Note that when using Q-Live, you can use the Video overlay with some stories and media files with others as required. When you switch between stories, Q-Live loads the appropriate media file or displays the external overlay input as required.
Configuration
The configuration options can be found in the Toolbox under Media>Overlay Config
When the card has been installed on the PC the video and audio settings can be controlled from the 'Overlay Config' option:
If the Audio option is OFF then there will be no audio in Wincaps.
If the card is selected then the 'Configure Video Device' and 'Configure Audio Device' takes you to the cards configuration settings.
