What is the method to make the video blurry and clearer? What is the reason for blurry video?

1. Adjust camera parameters
   When shooting videos, you can improve the image quality by adjusting the camera parameters. For example, increase ISO sensitivity, adjust shutter speed, increase aperture, etc. Adjusting these parameters can effectively improve the clarity of the video, but it will also increase noise or affect exposure. Therefore, when adjusting parameters, you need to make trade-offs based on the shooting environment and needs.
2. Use a Stabilizer
   During shooting, shake is one of the main causes of blurred videos. Using a stabilizer can effectively reduce jitter and make the video clearer. There are many types of stabilizers on the market, such as handheld stabilizers, selfie sticks, etc. Choosing the right stabilizer based on your shooting needs can greatly improve video quality.
3. Post-processing
   After the video shooting is completed, you can use post-processing software to improve the video clarity. Currently, there are many video editing software on the market, such as Adobe Premiere, Final Cut Pro, etc. These software have powerful video processing functions and can achieve clarity processing of blurry videos. By adjusting parameters such as sharpening and denoising, video clarity can be effectively improved.
4. Improve shooting skills
   Improving shooting skills is the fundamental way to solve the problem of video blur. During the shooting process, you must master the shooting rhythm and keep the camera stable; pay attention to the light conditions and try to shoot in sufficient light; use composition skills rationally to make the picture more beautiful.
   2. What’s the reason why the video is blurry?
5. Camera Shake
   During filming, camera shake is a common cause of blurry videos. In order to avoid shaking, you can use stabilizers, tripods and other equipment to fix the camera.
6. Shutter speed is too low
   Shutter speed refers to the time the camera lens is open. A shutter speed that is too slow will cause smear in the picture and make the video blurry. When shooting, the appropriate shutter speed should be adjusted according to the light conditions.
7. Inaccurate focus
   Inaccurate focus will cause blurry images. When shooting, make sure the lens is at the exact distance from the subject to get a clear picture.
8. Improper camera parameter settings
   As mentioned before, improper camera parameter settings can also cause video blur. Therefore, before shooting, you must be familiar with the parameters of the camera and adjust them according to the shooting environment.
   Methods for blurring and clarifying videos include adjusting camera parameters, using stabilizers, post-processing and improving shooting skills. By mastering these methods, we can effectively improve video quality and make the work more valuable to watch.
