What pixel camera is used for TV news interview and advertisement shooting?

Don't discuss pixels in the camera, because the pictures taken by the camera need to meet the broadcasting standards before they can be used in the radio and television system. At present, there are several common standards: PAL standard, 720× 576; NTSC standard, 720× 486; Hd 720p,1280× 720; Hd 1080i,1920×1080; Full HD 1080p, 1920× 1080. PAL, NTSC and 1080i all adopt interlacing technology, and the actual picture storage resolutions are 720×288, 720×243 and 1920×540 respectively. So the pixels corresponding to each format can also be calculated by resolution, but this figure is for reference only. PAL system, about 300,000; NTSC system, about 300,000; High-definition 720p, about 2 million; HD 1080i, about 2 million; Full HD 1080p, about 4 million.

In fact, ordinary TV does not require high pixels, but now there are many high-definition TVs, so there are two kinds of cameras for shooting TV. One is specialized courses, such as those adopted by TV stations. Generally, we don't look at the pixel standard, but calculate according to the TV standard. For example, 720P, 1080i and 1080p belong to the household category, and standard-definition (4: 3 normal screen) cameras all have pixel standards, which are generally 800,000 pixels. Sony's recent high-definition camera has a pixel standard of 5.66 million pixels and a picture resolution of 1080i.
