Tips: How to Blur Moving Faces in Video by Keyframes
When making the video face blurry, one of the questions is how to make the effect perfect once the face is moving. Apparently, adding a lot of blurring effects to the timeline is not a good idea. That's why you need to learn how to use keyframes.
Copy the video track to create a new layer, and crop out the face need to blur
At the very beginning, you need to duplicate the original video track, and then crop out the face area you want to blur in your video. To crop out a part of the video, click the "Crop" icon from the toolbar, select "Custom" from "Aspect Ratio", and then adjust the area on the canvas freely. When you finished it, click "OK".
Click the "Keyframe" button from the toolbar to apply it
You need to click "Keyframe" at the beginning and end respectively. Move the handle to the place you want to start. Then click the "Keyframe" button, play the video, or move the handle to the endpoint.
Hit the "Keyframe" icon again, and change the position of the blurring area
Hit "Keyframe" at the endpoint, then you can re-position the face blurring area as per your needs. In this case, the blurring area will be moving according to the face moving in the video. By the way, you can create as many keyframe effects as your want. And usually, you need to produce many keyframes to make the result perfect.

VSDC is one of the best video editing software for Windows users. It is powerful, multi-functional, and watermark-free. Users can use VSDC to start a new project directly, such as screen recording and slideshow generation. However, we advise veteran users to download VSDC because it is complicated and even the basic trimming and cropping inside of it have a hard learning curve. Here, you will learn how to blur out faces in a video like a pro.
Get VSDC for free. Import video files. And add blurring effect to the screen
Most features of VSDC are free, including recording, trimming, exporting, and blurring. But only Windows users have the channels to download it.

Edit the DeLogo filter settings in the right-hand panel
Find the "DeLogo filter settings" in your right-hand place to change the blurring content to pixelate, box, lens, mosaic or gaussian. You can also edit the position and blurring level based on your requirements.
Navigate to "Export project" on the menu. Download the edited video

iMovie: How to Blur a Face in a Video for Mac
Want to grasp how to blur faces in videos with iMovie on your Mac? You can directly find the iMovie software inside the macOS system, and begin to edit a video with a library of video effects. However, you need to prepare your own blurring picture from somewhere else. It can be a website or a local folder. That is to say, unlike AceMovi, iMovie has no blurring effects. But it won't affect that iMovie is a brilliant video face blurring option. Follow the tutorial below.
Launch iMovie. Add both the video and blurred image to the timeline
When entering iMovie, start a new project with local video files imported. At the same time, you need to add a blurry image to the Media panel. Then, drop both files under the timeline for editing.
Hit the first icon from the toolbar to pick up "Picture-in-Picture"
You have the two files dropped on the timeline. Click the first icon on the toolbar to set the display as "Picture-in-Picture". Then move the blurring image under the face you want to blur out.
Add a keyframe at the playhead to blur moving faces in your video
You need to use keyframes to make moving faces become blurry in the video. In the top-left place, you can find and use the keyframes. And you need to change the position of the blurring area when you apply the keyframe feature every time.
VN: How to Blur a Face in a Video on iPhone and Android
If you want to use your cell phone to blur faces in a video, then you must choose VN, which is a smart video editor app compared to others, such as InShot and KineMaster. VN creates video projects with music, text, effects, filters, and transitions. More importantly, you can use a streamlined timeline in both iPhone and Android with VN to edit batch files at the same time. 1080p (Full HD) and 2160p (4K) resolutions are supported by this app.
Install VN, start a new project, and import video to the interface
The app is free to use and download to a large extent. In other words, there are still some features that require you to pay for them. On the user interface, click "+" and "New Project" to produce a new video editing work. Pick up the video to add it to the timeline. Then click "+" from the "Pic" track to insert the blurry image.
Edit the face blurring box on the screen, use keyframes to blur the video
You're allowed to adjust the position and duration of the blurring content on the performance monitor. Then click "Mask" > "Radial" to make the blurring area become a circle. When making moving faces blurry, hit the "Keyframe" option on the pop-up panel. Every time you need to change the blurring area, you should click "Keyframe" and play the current project (or move the handle).
No matter whether you need to blur out still faces in a video, or moving/animated faces, those video effects editing software and apps are powerful enough. Rather than blurring faces, you can try mosaic the part of your video as well. When you've added the effect to the video and applied the keyframes successfully, remember to stipulate the blur amount.
