Keep the motion. Lose the room.
Built for the 9:16 talking-head clip that has to sit over a screen recording. Handheld, shot in a real room, hair moving. The awkward case, in other words.
What breaks on social footage specifically
Short-form vertical footage combines handheld motion, busy rooms, and changing light. Temporal video matting uses context across frames to keep the subject edge more stable through those conditions.
The room is not a set
Kitchens, bedrooms, cafés. Cluttered backgrounds with objects at the same depth as you are the norm, not the exception, and a model trained only on controlled studio footage struggles.
The camera is in your hand
Walking shots, gesture, the phone drifting. Following the subject across frames is what keeps the edge from wobbling or shifting between frames, which is why a frame-by-frame image tool falls apart here.
You are close to the lens
Short-form is shot tight. Hair fills a large part of the frame, so hair quality is not a detail on these clips, it is most of the visible edge.
It gets scaled down hard
The final clip plays at phone size. That forgives a lot, but it does not forgive flicker, because flicker remains visible even on a small phone screen.
In-app removal against a dedicated matte
Editor built-in removal
Tuned for speed on a phone, not for edge quality
Usually outputs the flattened clip only
Hair collapses to a hard outline at the edges
Result is locked inside that app
Free, and adequate for a static shot
Dedicated matting
Tuned for edge quality, runs in a queue
Transparent WebM carrying a real alpha channel
Individual strands survive against a busy room
Layers over anything in software that reads WebM alpha
Transparent output you can reuse across the editing workflow
Questions people actually ask
Does it keep my 9:16 aspect ratio?
Yes. Nothing is cropped, letterboxed or padded. What you upload is what comes back, minus the background.
Can I use this in CapCut?
That is not ours to promise. What you get is standard WebM with VP9 alpha; whether an app imports it depends on the app, its version and your operating system, and we will not speak for software we do not publish. Try one clip. If it will not read WebM alpha, convert to a transparent format that app’s own documentation lists, because renaming the extension changes nothing.
How long can a clip be?
Process videos up to 60 seconds long. Each signed-in account can complete up to 3 successful jobs per 24-hour allowance window at no cost.
Will it handle me walking around?
Usually yes. Motion is the case temporal matting is built for. The one that trips it is walking in front of a window with strong backlight, so test that specific setup on a free export first.
Your next transparent video is one upload away.
