Step 1: Import Your Footage
Import your video footage by selecting “File” > “Import” > “File” and choose your video file.Step 2: Create a New Composition
Drag your video from the Project panel to the Timeline panel. This will create a new composition with the same settings as your video.Step 3: Add an Adjustment Layer

To apply the blur effect, you need to create an adjustment layer. Go to “Layer” > “New” > “Adjustment Layer”. This layer will hold the blur effect.

With the adjustment layer selected, go to the “Effects & Presets” panel and search for the “Gaussian Blur” effect. Drag this effect onto your adjustment layer.Step 5: Adjust the Blur Amount

In the “Effect Controls” panel, increase the “Blurriness” value of the Gaussian Blur effect to achieve the desired level of blur.Step 6: Mask the Area to Blur
Select the adjustment layer and use the “Pen Tool” (shortcut: G) to draw a mask around the area you want to blur. You can also use the “Rectangle Tool” or other shape tools for simpler shapes.Step 7: Feather the Mask

To make the blurred area blend more smoothly with the rest of the video, increase the “Mask Feather” value in the “Mask” settings. This will soften the edges of the mask.Step 8: Animate the Mask (Optional)
If the object you want to blur is moving, you can animate the mask path. Select the adjustment layer, open the Mask Path settings, and click the stopwatch icon to add keyframes. Adjust the position of your mask at different points in time to follow the moving object. Step 9: Review and Export

Once you’re satisfied with the blur effect, preview your composition to ensure everything looks good. Then, export your video by selecting “Composition” > “Add to Render Queue” and adjust your export settings as needed.
