Put yourself over the thing you are talking about.
Talking-head footage composited onto a screen recording, a slide, or a clip you are reacting to. No cloth behind you, no colour spill in your hair.
The overlay problem
The format that performs is you in the corner while something else fills the frame. Doing that properly used to mean a green screen in your room, three lights, and a spill pass on every clip. It also meant never wearing green.

How this runs in practice
Record where you are
Kitchen, desk, hotel room. The background does not need to be clean because it is not going to be there.
Remove the background
Upload the vertical clip and get back a transparent WebM that keeps hair detail against a busy room.
Layer in the edit
Drop it over your screen capture in an editor that reads WebM alpha. Scale and position freely, the edge holds.
What to expect on this kind of footage
These notes show where BGRemove works well and where footage may need extra review.
Vertical 9:16
Native
Aspect ratio is preserved. Nothing is letterboxed or cropped on the way through.
Handheld motion
Handled
Camera shake and walking shots stay stable because the matte tracks per frame.
Glasses and jewellery
Mostly
Frames survive. Very thin wire arms against a bright window can drop out.
Worth knowing.Backlit footage shot straight into a window is the hardest case. It usually works, but check the free export before you build a whole series on it.
Product video
Shoot the product once, then drop it onto whatever background the season calls for. The transparent video becomes a reusable asset for every version you create.
Agency delivery
Automated matting handles the routine edge work and returns transparent files your artists can take straight into the composite.
