The total number of images extracted from the video will become 9 (1 image x 9.13 seconds).įfmpeg -i input.mp4 -vf scale=640:-1 %04d.pngįor example, the command above sets the width to 640 pixels. The frames of the video will be dropped as the original frame rate is 30 fps. On the contrary, the frames of the video will be duplicated if the original frame rate is lower.įor example, adding -vf fps=1 to the basic command will re-encode the video to 1 fps. If the original frame rate of the video is higher than the specified frame rate, the frames in the video will be dropped to match the frame rate specified. It is a filter that will convert the video to the specified constant frame rate by duplicating or dropping frames as necessary. You can change the frame rate by adding the argument -vf fps or -filter:v fps with the number of frames to the basic command. We can generate different outputs by adding some extra arguments to the basic command. This is because the length of the video is 9.13 seconds, and 30 images will be generated from every second of it (30 images x 9.13 seconds). As a result, a total of 274 images will be generated from the input video. This means that 30 images will be extracted for every second of the video when running the basic command ffmpeg -i input.mp4 %04d.png. You should get a result similar to this:įrom the screenshot above, the frame rate of the video is 30 fps. The information about the video will be printed in the terminal.
This is the basic command for extracting images from a video using FFmpeg:
