Keyframes
In keyframing, I use rotation and scale keyframes with ease-in/ease-out to create smooth motion. I also experiment with overlapping motion for natural movement.
Masking
In masking, I simply use the pen tool to trace the outside of the window and inverted it to the background video that's playing.
Track Matte
In track matte, I converted every lyrics into track matte in a background video. This song is titled Hardfeelings/Loveless by Lorde.
Tracking
In tracking, I use track motion and apply it onto the subject. This video was taken during A Matter of Time Tour played by Laufey.
