1, yes, the data of 1080 is larger and of higher quality than that of 720 (not counting post-compression). There is no difference between the two below 50 inches, and above 50 inches 1080 is indeed much clearer than 720. The mobile phone can't shoot 1080 video at present.

2. The effective pixel of1080 is 207W, which the mobile phone can do, but it is the size of a frame. If you want to have a smooth 30 frames per second, the mobile phone traffic can't be handled, and the reading and writing speed is far behind at present.

3. The size of the photo is not only related to the resolution, but also related to the compression ratio and the amount of information contained in the photo. Simply put, photos with complex colors are much larger than monochrome photos of the same size.

4. Size is mainly related to pixels. See item 3 for specific dimensions. The larger the aperture range, the better, and the larger the photosensitive element, the better.
