Remove an object from a video without cropping the frame

Upload a short clip, paint the unwanted object, and generate an edited version. The brush is sampled into keypoints for the AI, while optional keep points help protect nearby details you do not want changed.

AI video object remover controls

  • Paint-based selection

    Paint over the full object instead of describing it in text. Brush width affects the keypoints sent to the video eraser.

  • Keep points for nearby details

    Click a detail that must remain untouched, such as the edge of a product or a person beside the object being removed.

  • Short-clip workflow

    The tool accepts videos up to 5 seconds, making it practical for social clips, product shots, and short corrections.

  • Audio preserved by default

    The edit targets the video image. The original audio track is included in the MP4/H.264 output by default.

When to remove unwanted objects from video

  • Clean a product demo

    Remove a temporary prop, cable, reflection, or background distraction when the rest of the shot is still useful.

  • Refine a social clip

    Remove a photobomber or small visual distraction without reframing the entire clip.

  • Prepare a focused tutorial

    Reduce clutter around the part of a screen recording or hands-on demonstration that viewers need to follow.

  • Review an alternate edit

    Generate a revised short clip for editorial review before deciding whether a reshoot or manual compositing is needed.

How to remove object from video

  1. 1

    Upload a clip up to 5 seconds

    Choose an MP4, MOV, or WebM file up to 500 MB. Trim longer footage first; this tool does not silently cut your video.

  2. 2

    Paint the object to remove

    Cover the target with the brush. The app samples the painted area into positive keypoints, so use a brush size that covers the object rather than only its outline.

  3. 3

    Add keep points when needed

    Use keep points for nearby visual details that should remain. They become negative keypoints in the AI request.

  4. 4

    Generate and review the MP4

    Submit the selection, then review the resulting MP4/H.264 video before publishing it.

Remove object from video use cases

  • Remove a person from video

    Mark an unintended passerby in a short, simple shot when the surrounding background provides usable context.

  • Remove filming equipment

    Select a boom edge, stand, cable, or small production artifact that enters an otherwise usable clip.

  • Remove a temporary sign or prop

    Create an alternate product or location shot after a temporary object has been painted for removal.

  • Reduce background clutter

    Focus a short marketing or tutorial clip by removing a small distraction away from the main subject.

  • Remove text or a visual label

    For text, captions, or labels you own or are authorized to edit, paint each visible character. Complex motion, overlap, or detailed backgrounds can require manual editing.

Get better results from video object removal

  • Use a clip up to 5 seconds. Longer uploads are blocked so you can choose the correct segment yourself.
  • Paint the whole target and use keep points around edges that matter. A partial selection can leave part of the object behind.
  • Results are easier to review when the removed area has visible surrounding background. Large objects, fast cuts, occlusion, and complex motion can require a different source clip or manual editing.
  • The service processes clips at up to about 750p; 24 FPS is recommended. Inspect the output before publishing.

Frequently Asked Questions

How do I remove an object from video?

Upload a video up to 5 seconds, paint over the object to remove, add keep points if nearby details need protection, and generate the edited MP4.

Can I remove a person from video?

You can mark a person as the removal target. Review the result carefully, especially when the person overlaps another subject or covers a detailed background.

What are keep points?

Keep points identify nearby image details that should not be removed. They are sent as negative keypoints, while the painted selection is sent as positive keypoints.

Why is my video rejected for length?

This AI video object remover accepts clips up to 5 seconds. Trim the footage yourself so the submitted segment is the one you intend to edit.

Will audio remain in the edited video?

Yes. Audio preservation is enabled by default, and the output uses MP4 with H.264 video.

Which video files can I upload?

Upload MP4, MOV, or WebM files up to 500 MB. For best compatibility, use a short clip at approximately 750p or below and 24 FPS when possible.

Can I remove text from a video?

You can paint text, a label, or a caption you own or are authorized to edit as the target. Review the output carefully where text crosses a moving subject or detailed background.
