For example, if the video runs at 24 frames per second, it means there are 24 images displayed on your screen every second when the video is playing.
This command allows you to extract specific frames from a video, which are basically image files that make up the video. Output.mp4 is the output file, you can rename it as you need.

E.g the example below will output 1 image every 450 seconds ffmpeg \ You can extract images every time interval by using fractions. If you want to prefix with 0's on the output images, use image_%03d.jpg for image_001.jpg, image_002.jpg etc. Outputs will be image_1.png, image_2.png, image_3.png You can specify a value up to 31 for more compressed images, but I go with the highest quality and perform my image manipulation later with other tools. The -q:v 1 tells FFmpeg to take the highest quality image possible. There is a chance this may result in artifacts, but it is much faster. ffmpeg \īy placing -ss parameter ahead of the input, FFmpeg will seek to the closest point in the file first, and then take the screenshot.
