In this software era, video player often comes with a feature that can screenshot video scene in still image format while playing. Some of the software that provide this feature are VLC and Video. If I’m on Windows OS, my choice player is probably SMPlayer. SMPlayer can extract multiple frames in one click, VLC and Video can’t. I have the program on my Ubuntu but I don’t know why the screenshot feature is not available. If you have the same problem as mine, there is another method.
We still can extract video still images/frames with ffmpeg via terminal. But first make sure your video file in home directory and rename it simple just to make it easier when you type the command. Now, type the command like below on your terminal. It won’t ask you password like usual.
