I filmed the clip in my bedroom, not in front of a green screen. Here's what actually worked.

Most "remove video background" tutorials assume you set the shot up first: a green cyclorama, two softboxes, maybe a C-stand. I didn't. I had a talking-head clip shot against a beige wall with a lamp in the corner, and I needed the background gone for a slide deck.

Traditional chroma key can't help here. There's no green to key out. What you actually need is a model that finds the subject on every frame instead of subtracting a color. That's the difference between "green screen removal" (subtracting a known color) and "background removal" (segmenting a person frame by frame, regardless of what's behind them).

What I tried first

I tried cutting a still frame in Photoshop and reusing the mask across the timeline. Doesn't work once the subject moves even slightly, edges drift. I tried a rotoscoping plugin in my NLE next. Technically possible, but it took over an hour for a 20-second clip, and the hair edges looked like they'd been through a paper shredder.

What worked

I ended up using removebackgroundfromvideo.com's no-green-screen tool. You upload the clip as shot (MP4/MOV/WebM, up to 30s and 100MB on the free tier) and it segments the subject per frame instead of keying a color. A 30-second clip took about 5 minutes. I could tab away and come back.

The honest caveat: hair and fine detail still aren't perfect. My curls kept a faint halo from the room light, and a plant leaf behind my head left a slight green smear on one frame. If you need broadcast-grade edges on flyaway hair, you're still better off with a proper green screen. For a slide-deck talking head or a product demo where "good enough at normal viewing distance" is the bar, it held up fine.

One thing I'd flag before you commit: check what file format you actually need before you spend credits. I wasted my first attempt exporting a green-screen MP4 when I actually needed a transparent WebM for a web page, and the tool offers four output types (transparent WebM, ProRes 4444 MOV, green-screen MP4, alpha mask) and picking the wrong one means redoing it.

If your footage was shot in an ordinary room and you don't want to reshoot, this is the category of tool to look at. The constraint isn't your studio setup anymore. It's how well the segmentation model handles your specific edges.
