AI Video Background Remover

Separate a moving subject from its setting.

Remove a video background in roasOS Effects, with frame-by-frame review for edges and motion.

Start with a clear creative job.

A moving cutout can help place a presenter or subject into a new creative composition. Unlike a still mask, it must remain stable over time. Start with a source where the subject is visible and reasonably separated from the background, then inspect the result around movement, hair, hands and partially transparent details.

What to bring

Video with a visible subject
Destination composition
A plan for reviewing motion and edges

From brief to reviewed creative.

01
Prepare the source clip
Choose the useful time range and ensure the subject is not cropped in a way that breaks the intended composite.
02
Run background removal
Use the video background-removal action in Effects. Follow the current source and output constraints shown for the workflow.
03
Check the moving boundary
Review the full result against the destination. Look for disappearing fingers, edge chatter and leftover background before assembling the final ad.

A brief to adapt.

Illustrative starting point—replace it with your actual product and approved information.

Isolate this authorized presenter clip for a new composition. Review hair and hand movement against a contrasting background before using the result.

Before the asset becomes an ad.

Boundary stays stable through motion
Subject is not clipped
Destination lighting and scale make sense

Available models, inputs and credit estimates depend on the selected workflow. Check the current controls before generating, and review the final asset in its intended placement.

Questions about this workflow.

Is this the same as image background removal?

No. A video mask must remain stable across frames. A source that works as a single still may still create distracting edges in motion.

Can I assume a transparent export?

Check the selected workflow’s supported output format and compositing requirements. Do not assume every video format preserves transparency.
