You want to add an artificial blur effect to your video clips. Maybe because they are night shots without much light, or because you want to highlight the action with a cinematic flair. Or maybe you just like the look of artificial blur on moving faces. Whatever the case may be, this is a challenge for anyone who wants to do it right in their video editing software rather than relying on filters and effects within the camera app itself. The process is not as complicated as it looks, but you do have to know which tools and techniques to use in order to achieve your desired result. Thankfully, there are plenty of ways that you can make this happen with ease and speed. Let’s see how you can add blur to a moving face with the help of AI.

Part 1: What is Artificial Blur?
Artificial Blur is a term used to describe the process of blurring or anonymizing faces in digital images using AI technology. This can be done for a variety of reasons, including privacy, security, and aesthetic purposes. There are a number of different ways to achieve artificial blur. One common method is to use a face detection algorithm to identify faces in an image, and then apply a blurring filter to those areas. Another approach is to train a neural network to generate blurred versions of faces from input images.
The results of AI face blur can vary depending on the method used, but often result in a realistic-looking blur that preserves important details like facial features. This makes it difficult to reverse the process and identify the original subject. Artificial intelligence blur can be a helpful tool for protecting the privacy of individuals in images, as well as for improving the aesthetics of an image by creating a softer, dreamlike effect.

Part 2: Why Add Artificial Blur to a Moving Face?
The main reason you may want to add artificial blur to a moving face in your shots is that you want to create a shallow depth of field effect in the shot so that the subject is in focus and the background is out of focus. This is especially useful if you want to highlight the action of your shot by focusing on the subject while using the background as a cinematic backdrop.
Another reason you may want to add artificial blur to a moving face is if you want to create a dreamy, hazy, or ethereal look in your shots. This is especially useful if your shots are night shots without a lot of light or shots that are otherwise not naturally well-lit. By adding artificial blur to the moving face in your shots, you can create a dreamy look in your shots that is consistent across the entire shot. This can be useful if you want to give your shots a consistent feel that is different from what would typically be seen.

How to Add Blur to Moving Faces in A Video?
Step 1 Import your original video
First of all, you will need to download the installer of AVCLabs Video Blur AI onto your computer. After installing, launch it and you will see the intuitive interface shown below and import your source videos to the program.
Step 2 Scan human faces in your video
CAfter adding the video, you need to scan the faces in the video. Go to the "Face" tab, and you will see two options: All Faces and Custom Selection. You can blur all faces in the video or select the certain face you want to blur.
All Faces: If your video contains multiple faces, just select the All Faces option, then the program will automatically blur every face scanned.
Custom Selection: After the face scan process is completed, all the scanned faces will appear in the right panel, you can check any face, and then choose to blur face(s) you did select or blur face(s) you did not select.
Step 3 Choose blurring type
Adjust the blur style, size, intensity, and color in the right panel.
Step 4 Start adding blur to moving faces
After all settings are done, you can click Export to add blur to moving faces. When the face blurring process is completed, you can open the file folder and check the final video with faces blurred.

4. Super AI
Super AI is an online tool that can automatically blur faces in photos. It uses advanced artificial intelligence algorithms to detect and blur faces, making it perfect for privacy-sensitive photos.
There are many reasons why you might want to blur faces in images. For example, if you are sharing a photo of a crowd, you may not want people to be able to identify individual faces. Or if you are publishing a photo of a crime scene, you may want to protect the identity of witnesses or victims. Super AI makes it easy to blur faces in photos, so you can share them without worry.
Super AI uses advanced artificial intelligence algorithms to detect faces in images. Once a face is detected, it is automatically blurred. The blur is adjustable, so you can control how much of the face is visible.
Pros and Cons of Using AI Face Blur
Adding blur to a moving face can be a useful way to protect someone's identity. AI-based face blurring is a relatively new technology that is still being developed, but it shows promise for applications such as surveillance footage or online video chats. There are a few different methods for AI face blurring, but the most common one involves using a Deep Learning algorithm to detect faces in videos and then apply a blur filter to them.
One of the benefits of AI face blur is that it can be applied automatically and doesn't require any manual input from the user. This means that it can be used in situations where it would be impractical or impossible to manually blur faces, such as with security footage or live video streams. AI face blur can also be applied to images that have already been captured, which means that it can be used retroactively to protect the identity of someone who didn't want their face to be shown.

There are a few potential downsides to AI face blur, however. First, it is still an emerging technology, which means that it is not yet perfect. There may be some cases where AI face blur fails to correctly detect a face or apply the blur effect properly. Second, AI face blur can potentially reduce the quality of an image, especially if it is applied heavily. This means that it should be used judiciously and only when absolutely necessary.
Conclusion
Overall, AI face blur is a promising new technology with a lot of potential applications. It is still being developed and improved, but it shows great promise for protecting the identities of people in images and videos.
If you're looking for a way to add blur to a moving face in your video, AVCLabs Video Blur AI is a great option. This AI-powered software makes it easy to achieve realistic results, and it's also very user-friendly. You can even preview the results before you apply them to your video.
