I can do them using paint only.
You play the video in a player of your choice, and press PRINT SCREEN twice.
For some reason it takes a couple times for the video image to be captured.
Then you go into paint and paste it, take the next frame you want to use, do the same thing in a separate paint window, crop the skier and surroundings you still want, paste it accordingly next to the previous one so it lines everything up.
And keep going until the last frame.
