Video resolution (4K, 8K, fps)

The size and frame rate of video. 4K at 60 fps is smooth and detailed; 8K is larger but rarely needed.

4K video is about 3840×2160 pixels, 8K about 7680×4320. fps (frames per second) sets smoothness: 30 fps is standard, 60 fps smoother, 120 fps allows slow motion. Higher settings make much bigger files.
