What is a video object remover?

A video object remover is an AI editing tool that removes a selected object from video frames and reconstructs the background behind it. With UnmarkAI, you upload a video, brush over the unwanted area, and process the clip without cropping the original frame.

When should I use brush masking instead of full-frame cleanup?

Use brush masking when the unwanted object is specific: a passerby, prop, cable, cup, bin, cone, moving cyclist, reflection, or visual distraction. The mask tells the AI which pixels to change, so the rest of the video can remain visually stable.

Can it remove moving objects from video?

Yes. For a moving object, pause on a frame where the object is clear, paint the mask, and enable auto tracking. The task includes that mask time so the AI can track the selected object across the video.

What content can I edit with UnmarkAI?

Use UnmarkAI only for videos you own, licensed clips, client-approved assets, or footage you otherwise have permission to edit. Do not use object removal to misrepresent events, bypass rights, or remove required attribution.
