Use this command to toggle the video devise between Freeze and Unfreeze modes. When the video is frozen, the content of Video window remains unchanged and the capture functions will create images from the frozen video frame. A check mark will appear next to the Freeze command in the menu and the button on the video tool bar will remain pressed. To unfreeze the video, apply the same command again.
If the video device is working in the trigger or start/stop mode, this command will be unavailable.
