How to Create Edge Mask Effect in Premiere Pro Similar to Alight Motion

[ham7373.]

Hi, I am trying to make the video style shown in the attached example. I know how to do this in Alight Motion but not in Premiere Pro. I will explain the steps I use in Alight Motion so you can understand what I am trying to do.

1. I put the clip on Track 1 and the template on Track 2.
2. Then I use the Chroma Key (Ultra Key in Premiere Pro) and use the black dropper to select the black area. This makes the clip show in the black parts.
3. After this, in Alight Motion, there is a "Blending" option where I select "Mask" and then "Exclude Mask." This makes the white area transparent and automatically creates the edge mask. So, I get the clip styled with edges, and the white parts are transparent.
4. At the end, I nest this and place the same clip in the background.

How can I do the same in Premiere Pro?

Here’s how you can create an edge mask effect in Adobe Premiere Pro, similar to Alight Motion:

Step 1: Add the Background

1. Add your video to Track 1.
2. Scale it up to fill the frame.
3. Apply the Black & White and Gaussian Blur effects to this clip, then increase the blur to your preference.

Step 2: Add the Video with the Mask

1. Add your video again to Track 2 and place the Luma Matte layer on Track 3.
2. Apply the Track Matte Key effect to the video on Track 2.
3. In the Effect Controls panel:
   • Set Matte to Track 3.
   • Set Composite Using to Luma.
   • Check the Reverse option.
4. Now your video will be masked using the Luma Matte.
5. If needed:
   • Use the Offset effect to reposition your masked video.
   • Use the Transform effect to scale your masked video.

   
   Note: Ensure that these effects are applied before the Track Matte Key effect in the Effects stack.
