Download ffmpeg from here (ffmpeg is also available via brew)

Use the following bash command:

$ ffmpeg -i <videofile> -vf fps=1/10 frame%04d.png

Notes on this command:

• Replace <videofile> with the path to the video file you wish to process
• fps=1/10 is the frames per second (grab one frame every ten seconds)
