Snagit is a screenshot program that captures video display and audio output. Snagit screen capture allows you to grab an image or video of what you see on your computer screen, add effects, and share with anyone. Snagit Capture Interface Snagit’s image and video capture is powerful, but not complex. You’re in control of everything you capture, right down to the pixel. All-in-One Capture® grabs your entire desktop, a region, a window, or a scrolling window from any webpage or application—all with a single hotkey or click.
