What are the benefits of shooting 4k video?

The advantage of shooting 4K video, the greatest significance of shooting 4K video is that we can have more flexible cutting space in the later stage, and we can choose any picture at will. The enlarged picture can still be clear within twice the amplification range of a certain part, so the following advantage is that the first boring shot will move without losing the picture quality after exporting the 4K picture to 1080P video in the previous stage, and the second composition will remedy the mistakes of the previous composition. Sometimes, third, improve the image quality, effectively reduce the noise in the shadow part, and bring better operation experience for the later special effects synthesis; Fourthly, recording 4K video and intercepting 4K photos are suitable for single dog to record his single moment and capture some interesting moments.

Why do you want to shoot a 4K video?

First of all, it's convenient for us to take pictures, because when we take a video, just like the original view of our video is like this, there are many things around us that shouldn't be in the camera. 4K shooting can enlarge our picture twice, and it is still the same as shooting only 1080P P p, and if the camera is not adjusted in the early stage, we can adjust it later. And there will be many mistakes when recording video, so we have to edit it later. However, if you cut it directly, will it be like this, and will you feel that the picture is very incoherent? At this time, if you enlarge the picture to simulate the shooting of multiple cameras, you will feel that the picture is naturally connected, as if two cameras were used, but in fact there is only one. This is the advantage of 4K shooting.
