The actual method really does take only about 30 seconds. I've included additional info as well in the video so that you can get even more out of this trick, so that's why the video is longer than 30 seconds. :-) This method of removing video flicker is a variation of a method I first learned from Philip Bloom, which I ended up using extensively (and adapting as-needed) when working with slow motion footage that I shot in Europe this past May. The best way to deal with flicker is to shoot in such a way that you don't have it in your footage in the first place. This can be done by ensuring your frame rate and shutter speed are offset from the speed of a flickering light source, such as LEDs or Fluorescent lights. But what if you've shot something and you didn't realize there were flickering lights until you were reviewing the footage later? In this case, here's a quick trick that can help fix it. This won't work in all scenarios, but it's an easy first step to take to see if it works. I hope this was helpful!
