The program itself will save frames from a video file to a sequence of JPG images. For that purpose, you need a program that can extract however many video frames you want and save them to image files automatically, like jpg or png. If you want to extract a succession or range of frames or even all frames from a short video clip, capturing the images one at a time is incredibly inefficient and time consuming. If you want to capture an image of one or two frames it’s quite easy and you simply pause the video and press the Print Screen key. A video file on a computer simply stores all the frames together and plays them in order, and the total frames stored for a typical movie reaches into the hundreds of thousands. Most movies and TV programs are filmed at around 24-30 images per second, each individual image is called a frame which is where you see the term frames per second (FPS). The quicker the images are played, the smoother and more fluid the movement looks. These images are then played one after the other several times a second which fools your eye into thinking the object is moving. Every video or animation you see on your television, computer, phone, tablet or even at the movie theater is made up from a succession of still images.
