Choose Layer > Add Layer > Add Video Capture Layer... to create a new Video Capture layer.
After choosing this menu item, the new Video Capture layer is visible in the Layers listbox. You can use this listbox to switch between layers.
The video capture layer layer uses exactly the same interface and has the same features as the picture layer, only it operates on video material coming from a video capture device, like a webcam.
BluffTitler uses the first video capture device it can find on your system.
When creating an AVI file, BluffTitler only exports the visuals. Use the video capture layer only for realtime applications like digital signage or when audio isn't important.
