How can I grab individual frames from an .avi into an image?
[A] The most straightforward way of doing this is to run Cineplex Markup and hit the “Print Screen” button on the keyboard. Then just paste that into your image editor of choice and crop out everything but the frame. If that’s too time consuming for you, then I recommend using something like VirtualDub (or any other video editor) to quickly export frames into .jpg or other image formats.
