How To Add Mosaic to Blur Videos with PowerDirector

In this section, we will explain how to add mosaic, blur, and highlights using PowerDirector. First, we will explain how to add a fixed mosaic and how to have the mosaic automatically track the subject’s movement.

• Add Fixed Mosaic to Video

1. Import your video



When you launch PowerDirector, you will see a screen like the one here. Tap on "New Project" located in the center of the screen to start editing.

When you start a new project, you will see a screen to select the aspect ratio of the video. Here, you choose the frame of the video you want to edit. Choose the aspect ratio according to your purpose, such as 16:9 for YouTube or 1:1 for Instagram.



When you select a video, the editing screen will appear with the loaded video on the timeline, as shown on the right side of the figure above. Note that with PowerDirector, you can edit in both portrait and landscape modes. Set the "Change UI editing mode" option to the mode that suits you best or select "Auto-rotate". If you choose "Auto-rotate", you can switch between portrait and landscape modes automatically by simply rotating your smartphone.

2. Add Mosaic To Blur Video



Once you are in the editing screen, scroll in the tool menu to the left and find the "Effect" icon. There will be 4 different effects for you to apply to your video - Adjustment, Mosaic, Blur, and Highlight. 

Both Mosaic and Blur are image editing techniques used to obscure certain parts of an image or video. However, Mosaic creates a pixelated or blocky effect to completely hide an area of the video, while Blur creates a blurry effect to obscure but not completely hide the content.

3. Reshape the Mosaic



By tapping on Shape, you can change the shape of the mosaic. Choose the shape of the mosaic that you want to use depending on the atmosphere of the video or the position of the subject.

4. Resize the Mosaic



You can directly tap the mosaic and adjust its size, shape, and position by swiping or pinching in or out with two fingers. So adjust it to fit in the position where you want to put the mosaic.

5. Adjust Mosaic Strength



You can choose Strength and adjust the pixel degree of the mosaic by sliding the slider displayed on the bottom side of the screen from left to right. Additionally, you can tap Feather to blur the edges of the mosaic and adjust it for a natural look.

• Make Mosaic Move with the Subject

Next, let's try moving the mosaic to overlap with the subject.

There are two ways to make the mosaic track the subject’s movement. You can either use the AI Motion Tracking automatic tracking feature or manually move it using keyframes.

1. Using AI Motion Tracking

After inserting the mosaic, place the mosaic on the subject anywhere on the timeline as shown below. Next, select Motion Tracking from the bottom menu and tap Start Tracking.



After waiting for a few seconds, automatic tracking of the mosaic will be applied. You may press the play button in the middle to check the result.



2. Using Keyframes To Manually Blur Videos

Keyframe is a tool that allows you to freely move text, images, and other elements inserted into a video. It is an essential skill used by professional editors, but it can now be easily set up on smartphones.

First, follow the steps from the previous section to insert the mosaic.

Bring the playback head to the beginning of the video clip, select the mosaic clip, tap Transform Keyframe and tap the "keyframe" icon on the right side. You will see that keyframe marks are added to the mosaic clip in the timeline.



Next, move the playback head to the position a few seconds later and then tap and move the mosaic to adjust its position. Once you have moved the mosaic, tap the Keyframe icon again to check if a new keyframe has been added.

Repeat the process of moving the mosaic and adding keyframes at the desired positions a few seconds later. Once you have added keyframes through to the end of the clip as shown in the figure above, tap the play button to preview the final result.

How To Highlight a Video with PowerDirector

In addition to mosaic, you can add blur and highlights to the video. On the screen where you selected mosaic in the previous section, let’s select blur or highlight and try it out.

You can highlight the subject as shown in the figure below by selecting Highlight on the screen. All settings are basically the same as when adding mosaic to blur the video. Just like you can adjust the strength of the mosaic, you can also adjust the brightness if you want to apply a highlight effect to the video.
