3.2.1.2 Video set-up

On Linux, you can capture video directly into `nip2` provided that your capture card is compatible with v4l. You may need to adjust the `nip2` video settings. These settings can be found under the headings `Video for linux` and `General video capture` in the `Preferences` window, which can be accessed by selecting `Edit` / `Preferences` from the main `nip2` window. 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 `Tasks` / `Capture` / `Capture Video Frame` to create a new video object, which will appear as a still image in your current selected column. The captured image can be updated by opening the image in a viewing window and then pressing Ctrl-C (a shortcut for `File` / `Recalculate Image`).

You can create more than one video object: which 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.
