Extract all frames from a movie using ffmpeg
# Output a single frame from the video into an image file:
ffmpeg -i input.mov -ss 00:00:14.435 -vframes 1 out.png
# Output one image every second, named out1.png, out2.png, out3.png, etc.
# The %01d dictates that the ordinal number of each output image will be formatted using 1 digits.
ffmpeg -i input.mov -vf fps=1 out%d.png
# Output one image every minute, named out001.jpg, out002.jpg, out003.jpg, etc.
# The %02d dictates that the ordinal number of each output image will be formatted using 2 digits.
ffmpeg -i input.mov -vf fps=1/60 out%02d.jpg
