3.2.1.2 Video set-up

On Linux, you can capture video directly into nip provided that your capture card is compatible with v4l. You may need to adjust the nip video settings. These settings can be found in columns Video for linux and General vid capture on the Preferences workspace, which can be accessed like any other loaded workspace, by clicking on the tab in the bottom left corner. The default settings, see Figure 3.1, are for the Hauppauge PCI capture card and should be changed as required.

Once you have set up your card, select Capture=>Capture_video to create a new video object, and pop up a viewer for it. Press Ctrl-C (a shortcut for Edit=>Recalculate this window) every time you want to grab a new image.

You can create more than one video object: it can help you to get the overlaps right if you have two open at once (one showing the previous grab) when you are moving the camera around.
