Ffmpeg Solutions
Solution 1 - Ffmpeg
Official ffmpeg documentation on this: Create a thumbnail image every X seconds of the video
Output one image every second:
ffmpeg -i input.mp4 -vf fps=1 out%d.png
Output one image every minute:
ffmpeg -i test.mp4 -vf fps=1/60 thumb%04d.png
Output one image every 10 minutes:
ffmpeg -i test.mp4 -vf fps=1/600 thumb%04d.png

You can use the select filter for a set of custom ranges:
ffmpeg -i in.mp4 -vf select='between(t,2,6)+between(t,15,24)' -vsync 0 out%d.png

Another way is to use ffmpeg library for python, particularly useful if you don't want to add ffmpeg to your pc environment. Start by installing ffmpeg on conda with:conda install ffmpeg
Then you can write a script as bellow:
import ffmpeg
input_file_name = 'input_video.mp4'
(ffmpeg
.input(input_file_name )
.filter('fps', fps=10, round = 'up')
.output("%s-%%04d.jpg"%(input_file_name[:-4]), **{'qscale:v': 3})
.run())

In addition to the select filter in Gyan's answer (which I use with eq
rather than between
), I came across another filter in the manual: thumbnail
