I had bought a new SJ6 Legend a few weeks and I was able to use once only using the 1080p 60 fps vid during our trip to the beach. My problem was the feature on sj6 which was the 4k and 2k vid. Why is it that I cannot use it? It recorded but when I transferred it to my desktop, I cannot see any video except for its audio. What is wrong with it and how can use that feature? I am using a scandisk for my memory card.
