Artist/author here! Keyword in that quote is “tend to.” There are always exceptions.
That said, this video didn’t use real legos, I don’t think. I believe it was all done through an algorithm. And even if it was done with stop motion and real legos, you can bet dollars to donuts they used all the most up to date video editing software. Even if they wanted to capture a stop motion aesthetic, why on earth would they add man hours splicing 8mm film on top of it?
Anyway, hope you enjoyed the article overall!
