See how you can use After Effects to apply a track matte to a video captured on the go with Premiere Clip to create a hoverboard effect like the one seen in Back to the Future II.
If you want to re-create the effect shown in this video, copy the Hover Assets to your Creative Cloud Assets. Click Save to Creative Cloud to copy the assets to your own account.
- Shoot your sequence twice, with and without your moving subject.
- Import those background and foreground clips into After Effects.
- Go to Layer > New > Solid and use this to create a mask for the wheels or part of the footage you want to remove.
- Go to Window > Tracker and connect the anchor point of the solid to the wheels. In the Tracker panel click Track Motion.
