Key and motion track Adobe Stock green screen clips in Premiere Pro.

Search on Adobe Stock

Click Videos and then search for “guy holding cell phone green screen”.

License the selection and download it to your computer.

Note: You can also search and license directly inside Premiere Pro within the Libraries panel.

Import your green screen clip

In your Projects panel, or inside a Bin, right-click and choose Import.

Navigate to the location on your hard drive where you downloaded the licensed Adobe Stock clips, and select them.

In the Project panel of an Adobe Premiere Pro desktop screenshot, the editor selects “Import...” from the shortcut menu

Place your clips on a new timeline

In your Project panel, right-click on the video clip you intend to key into the green screen and choose New Sequence From Clip. This will place it on track V1.

Next, drag your Adobe Stock green screen shot onto track V2 above.

In the Project panel of an Adobe Premiere Pro desktop screenshot, the editor selects “New Sequence From Clip” from the shortcut menu

Nest your clips

Nest the clips that will be placed onto the green screen.

Select all the clips on track V1 that will be keyed into the green screen of the mobile device. Next, right-click over one of them and choose Nest.

This will nest the clips together into a new sequence, and open it as the active timeline.

In the timeline of an Adobe Premiere Pro desktop screenshot, the editor control + clicks on the V1 clip called Logo Build and selects “Nest...” from the shortcut menu

Change the aspect ratio

Now it’s time to change the aspect ratio of the nested timeline so it matches the mobile device.

Double-click the nested timeline in your sequence to open it.

Choose Menu Bar > Sequence > Sequence Settings. 

Change the Frame Size to 540 x 960. To confirm, Vertical should read 9:16.

Click OK.

Note: Once the aspect ratio has been updated to match the mobile device, you can double-click the clip in the Program Monitor and reframe it to your liking.

In the Sequence Settings window of an Adobe Premiere Pro desktop screenshot, the editor enters 960 in the vertical Video frame Size setting

Replace with After Effects Composition

Open After Effects in the background, with a new, blank project.

While it’s opening, return to Premiere Pro and select your original timeline — not your nested timeline.

Select both layers in the original timeline.

Right-click on both layers, and choose “Replace With After Effects Composition.”

You’ll get a Save dialog box in After Effects. Save the project to your hard drive.

In an Adobe Premiere Pro desktop screenshot, the editor control + clicks on both clips in the timeline and selects “Replace With After Effects Composition” from the shortcut menu

Apply Linear Color Key in After Effects

Back in After Effects, select just the top layer of your new sequence. 

Then in the Menu Bar, choose Effect > Keying > Linear Color Key

Note that the Linear Color Key defaults to the color blue, so you’ll see no change on your video track. To key out the green in our mobile device example, go to the Effects Controls panel in After Effects, and select the eyedropper to the right of the blue box. 

Then, using the eyedropper, click the green field of the mobile device in your Composition panel.

Track the green screen

Be sure that your Tracker panel is visible in After Effects. It’s standard in the rightmost panel, but if you don’t see it, you can enable it in Window > Tracker from the Menu Bar.

In the Tracker panel, click Track Motion. In the Track Type dropdown menu, choose Perspective Corner Pin.

Placing your cursor between the two small squares in the upper left corner of the big square tracker, drag it to the upper left corner of the mobile device. After Effects will automatically pop-up a magnifier for you to fine-tune your placement. 

Repeat for the three other corners.

Reduce the size of each of the four inside boxes to fine-tune your tracking to focus just on the corner.

Expand the size of the outside box in each corner to about double the standard. 

In the Tracking panel, click Edit Target. Note that it will automatically select the nested layer below. Click OK.

Next, click Analyze Forward: it’s the right arrow button in the Tracker panel.

Finally, if you like the tracking path it recorded, click Apply. After Effects should take you back to the main composition with the green screen keyed out.

Save the AE project.

Return to Premiere Pro

You will see your After Effects composite is dynamically linked and updated.

In an Adobe Premiere Pro desktop screenshot, the timeline shows a single clip and indicates that it’s dynamically linked to an After Effects composition


Export your video with a Premiere Pro preset for social media or desktop presentations.

We’re using a 1080p HD Vimeo preset that outputs a video we can drop into a PowerPoint presentation right from our computer.

In an Adobe Premiere Pro desktop screenshot, the editor selects the Vimeo 1080p HD Vimeo preset in the Export dialogue box for the .h264 format setting
