What tools exist for capturing consecutive screenshots of a film?

Question

Is there any tools that allow for capturing screenshots of a film at set intervals? E.g. something that captures a screenshot every second and saves them to files in an ordered sequence. I'm using Windows, but I'm open for Linux suggestions as well.

Answer 1

This can easily be done via ffmpeg, the documentation describes the process

For extracting images from a video:

ffmpeg -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg

This will extract one video frame per second from the video and will output them in files named foo-001.jpeg, foo-002.jpeg, etc. Images will be rescaled to fit the new WxH values.

If you want to extract just a limited number of frames, you can use the above command in combination with the -vframes or -t option, or in combination with -ss to start extracting from a certain point in time.

Answer 2

Perhaps AutoScreenShot will do what you need.
