Based on the information provided, the best video resolution and frame rate for a smooth and clear picture quality would be 4K at 30 frames per second (fps). While 1080p at 60fps can provide a slightly smoother motion experience, the higher resolution of 4K offers significantly more visual detail and sharpness. The 4K resolution records four times more information per frame compared to 1080p, resulting in a more detailed and high-quality image. This makes it easier to edit, zoom, and pan the video without losing quality. Additionally, the 30fps frame rate of 4K video provides sufficient motion smoothness, and the increased visual detail can be more beneficial than the slightly smoother motion of 1080p at 60fps, especially for content like travel videos or nature documentaries where capturing fine details is crucial.
