Overview
Keep a person or object in your video and choose a background option for your next edit. Describe the subject, select None (Transparent), Green Screen, Blurred, White, or Black, then review the result through the clip. A speaker in a busy room may need a different background choice from a clip intended as an overlay.
Describe the person or object to keep; the configured purpose is to track that subject through the video. Choose a Replace Background option and a Frame Rate setting, then process and inspect the result. Transparent output downloads as WebM; other background options download as MP4.
When to use
- Use this tool when you want to keep a person or object in a video and choose one of the listed background options. Pick an option for where the clip will go: a speaker in a busy room may need a different choice from a clip intended as an overlay.
- If you need to upload your own replacement image or set a custom color, those controls are not listed. The available choices are None (Transparent), Green Screen, Blurred, White, and Black.
How to use
Open AI Video Background Remover and use its linked workspace. Sign in and connect to the internet for this online workflow.
Upload one .mp4, .webm, .mkv, .avi, or .mov file. Check all limits together: maximum 25 MB, 60 seconds, 1,800 frames, and 60 fps; dimensions must be even and no larger than 3,840 × 2,160 pixels in total. At 60 fps, 1,800 frames covers 30 seconds. Trim the clip if it exceeds either the duration or frame limit, and review restrictions shown in the workspace.
In Subject to Keep, describe the person or object using visible details, such as “the speaker in blue on the left.” Enter 1–200 characters. Under Replace Background, choose None (Transparent), Green Screen, Blurred, White, or Black. Under Frame Rate, keep Auto (Match Original) or choose 15 FPS, 24 FPS (Film), or 30 FPS.
Use the workspace action to process the clip. When the result is ready, watch the subject through the clip before downloading. Check hair, hands, and moments when someone passes in front. If a download is offered, verify the file before using it; transparent output downloads as WebM; other background choices download as MP4.

Examples & use cases
A presenter preparing a short training clip.
Keep a presenter in a busy room
A 20-second MP4 shows a presenter in a blue shirt on the left, with a busy room behind them. The presenter wants the available Blurred background option for the lesson.
.mp4 to MP4
- Subject to Keep:
- the presenter in a blue shirt on the left
- Replace Background:
- blur
- Frame Rate:
- auto
- Use the presenter’s clothing and position in Subject to Keep to identify them in the shot.
- Choose Blurred in Replace Background for the requested available option. Keep Auto (Match Original) in Frame Rate rather than changing the frame-rate choice without a specific need.
- Watch the full clip and check whether the presenter remains the intended subject as their hands move or someone crosses in front.
Expected outcome
The registered deliverable is an MP4. Review the moving result to decide whether it suits the training clip.
A small-business owner preparing a product demonstration.
Keep a product in a short demo
A 15-second MOV shows one product on a desk. The owner wants the listed White background option for a catalog-style clip and needs to check whether the product remains the intended subject when moved.
.mov to MP4
- Subject to Keep:
- the product centered on the desk
- Replace Background:
- white
- Frame Rate:
- auto
- Describe the product’s position in Subject to Keep so the instruction identifies the object in the frame.
- Choose White in Replace Background because it is the listed option that fits the requested background. Leave Frame Rate at Auto (Match Original).
- Review the full clip, especially as the product is picked up or moved. Check whether it remains the intended subject.
Expected outcome
The registered deliverable is an MP4 with the White background option selected. Inspect the result before deciding whether it suits the catalog use.
A course creator editing a classroom segment.
Prepare an instructor clip for another edit
A 25-second MKV shows an instructor at the front of a room with other people nearby. The creator wants to keep the instructor and select Green Screen for a later editing step.
.mkv to MP4
- Subject to Keep:
- the instructor at the front of the room
- Replace Background:
- green
- Frame Rate:
- auto
- Describe the instructor’s position in Subject to Keep to distinguish them from the other people.
- Choose Green Screen in Replace Background for the requested listed option, and keep Auto (Match Original) in Frame Rate.
- Review moments when people pass in front of the instructor. Check whether the instructor remains the intended subject through those movements.
Expected outcome
The registered deliverable is an MP4 with the Green Screen option selected. Review the moving result and decide whether it fits the next editing step.
More ways to use it
- A remote presenter preparing a short lesson.: The presenter wants to keep themselves in the shot and choose a listed background option for a video that meets the supported input restrictions. An MP4 to review throughout the clip before using it in the lesson. Subject to Keep: the presenter, identified by visible clothing and position, Replace Background: blur, Frame Rate: auto.
- A product team preparing a short demonstration.: The team wants to keep one product as the subject and select a listed solid background for the clip. An MP4 with the Black background option selected, ready for review before the team decides whether it fits the demonstration. Subject to Keep: the product, identified by its position in the frame, Replace Background: black, Frame Rate: auto.
Troubleshooting
The clip is rejected even though it is under 60 seconds.
Try this: Check the file size, frame count, frame rate, and dimensions as well as duration. The limits apply together; trim the clip if it exceeds 1,800 frames or 60 seconds.
What to expect: If a listed input limit caused the rejection, bringing the clip within that limit should address that restriction. Review the workspace’s displayed restrictions before trying again.
The cutout edge flickers as the subject moves.
Try this: Review the moving result through the clip, paying particular attention to hair, hands, and moments when someone passes in front. No specific edge-flicker correction is documented.
What to expect: You can assess how the subject is handled across the moving clip rather than judging from a single frame; the review does not guarantee that flicker will be corrected.

Frequently asked questions
Can I upload my own replacement background?
No custom-background upload control is listed. Replace Background offers None (Transparent), Green Screen, Blurred, White, and Black.
Why does the cutout edge flicker as someone moves?
The tool is configured to track the described subject through the video, and the workflow recommends watching the result in motion. A specific cause or edge-flicker fix is not documented. Check the full clip, especially around hair, hands, and moments when someone passes in front, before deciding whether to use it.
Why was my clip rejected even though it is under 60 seconds?
Duration is only one limit. The file must also be no larger than 25 MB and no longer than 1,800 frames; it must be no more than 60 fps, have even pixel dimensions, and be no larger than 3,840 × 2,160 pixels in total. At 60 fps, 1,800 frames covers 30 seconds. Check every limit and any restrictions shown in the workspace.
Can I remove the background from an MP4 video?
Yes. .mp4 is an accepted input extension. The registered output format is MP4.
Which video formats can I upload?
The accepted extensions are .mp4, .webm, .mkv, .avi, and .mov. The registered output format is MP4. These extensions do not establish support for particular codecs or bit depths.
Can the processed video have a transparent background?
Choose None (Transparent) to request a WebM with transparency. Other background choices download as MP4. Test the WebM in your destination editor because transparency support varies.
Can I replace the video background with an image or custom color?
The listed choices are None (Transparent), Green Screen, Blurred, White, and Black. The registered settings do not list an uploaded image or a custom-color option.
What Frame Rate options are available?
Frame Rate offers Auto (Match Original), 15 FPS, 24 FPS (Film), and 30 FPS. The documented setting lists the choices but does not specify a separate quality effect for each one; review the processed clip.
Can I process several video clips at once?
The registered configuration allows one file per run. Upload one accepted video file for this workflow.
Does the result keep the original audio?
The registered output is MP4, but the capability sheet does not specify whether the original audio is retained. Check the downloaded file if audio matters to your project.
Does this tool work with GIF files?
GIF is not in the registered input list. The accepted extensions are .mp4, .webm, .mkv, .avi, and .mov.
Is my video processed locally?
Online processing uploads files. Completed results may remain available for later download. See Privacy Policy for current file-handling and retention details. Check the processing mode before starting.
Does this work for every type of footage?
The tool accepts the listed video formats and lets you describe a subject to track through the video. The result is not guaranteed for every kind of footage, so review it through the clip, especially during movement, before using it.
Do I need a physical green screen?
A physical green screen is not required. Describe the visible subject you want to keep and choose a replacement background, then inspect edges throughout the clip.
How specific should my Subject to Keep description be?
Use visible details that identify the person or object, such as “the speaker in blue on the left.” The field accepts 1–200 characters.
