John bought a Samsung Galaxy S7 to capture video and share it online. But when he records, he sees a lot of pixelation in it. Leo says it sounds like an odd compression issue. Leo advises trying different settings and using a different video camera app. He should also try a lower resolution or he should change the frame rate. If the issue persists, then it could be something called "macro-blocking" where a solid color like a sky ends up looking banded as a result of video compression. Cinema FV-5 could solve it also.
