Why can cameras take pictures?

Cameras with video functions can partially replace video cameras, but they cannot completely replace them. The advantages of using a camera to record video: 1. It can take pictures and record videos - although many video recorders can also take pictures, they are basically "video screenshots", which is a useless function. 2. For card cameras, they are usually more portable than cameras of the same price range. 3. For SLR/Micro single-lens cameras, because the CCD or CMOS is relatively large, the image quality is usually better than that of cameras in the same price range, and the lenses are interchangeable (cameras with interchangeable lenses are usually more expensive, and camera lenses are harder to buy). Advantages of the video recorder: 1. The holding design is more suitable for video recording - the holding method of the camera is suitable for taking pictures, but it is not as comfortable as the video camera when used for video recording; professional video cameras will be designed to be heavier and carried on the shoulder or hand to prevent shake. 2. When most cameras record videos, there will be an obvious jelly effect when encountering fast-moving scenes. The cameras usually optimize for this aspect. 3. Since the camera is relatively "long", the lens can have a large zoom range. 4. It is more convenient to record for a long time, such as meeting records, etc. Some cameras limit the video recording time. 5. A built-in microphone is usually better than a similarly priced camera. 6. Some professional cameras cannot be replaced, such as channel cameras (the kind that are directly connected to the broadcast station for on-site recording) and movie cameras that require an external recorder. 7. Usually the continuous autofocus function of low-end cameras is better than that of cameras of the same price. The current situation is that the camera functions are getting more and more powerful. Advertisements and micro-movies shot with SLRs are all over the streets. There is increasingly no market for low-end cameras (although the low-end camera market is also being eaten away by mobile phones), but after all There are specialties in the art industry, and it is wise to choose equipment based on the application scenario.
