Prepare footage for background replacement and know when it will work: clean edges come from how the shot was recorded, not from the tool alone. This page covers the shooting and checking process, since what the workspace supports depends on the current product state.
STEP 01
Even lighting, a subject that contrasts with the background, and no motion blur across the edge give the best chance of a clean result.
STEP 02
Look at the hair, the shoulders and any thin details at full size, because that is where separation fails first.
STEP 03
Keep the result if the edge holds, and if it does not, plan a background that hides the problem instead of publishing a damaged edge.
Separation works when the subject and the background are visually distinct: a lit subject against an evenly lit wall, or a green screen lit without hot spots and without colour spill onto the subject. Fast movement and a background that shares the subject's colour produce ragged edges that no amount of editing repairs.
Check four places at full size: hair and loose strands, the gap between arm and body, transparent or reflective objects such as glasses, and fast motion across the frame. If any of them fails, the shot is usually better re-recorded than fixed.
A busy replacement background draws attention to every edge imperfection, while a simple, softly lit background hides them. When the separation is borderline, changing the background is often faster than improving the matte.
Common questions about this task, its limits and how to judge the result.
Import the clip into an editor that supports video background separation, then inspect hair, hands and fast motion at full size. The exact control depends on the app and device.
Some tools offer a free entry point or trial, but resolution, duration, watermarks and export counts can be limited. Check current pricing and export terms before publishing.
Separate the task first: background separation replaces the whole background, while removing an object needs an object-removal or repair tool. They are not the same operation.
That depends on the tool and plan. Check upload duration, export format, resolution, watermark and credit limits before choosing it for your footage.
