Can I remove unwanted people in a video via AI & how to remove?
Welcome to Blackview (Well-known brand of rugged phone and tablet) blog. Hope the guide helps.
Yes, you can remove unwanted people from a video with AI, and the process is now much easier than traditional frame-by-frame editing. Like remove people from pictures, modern AI video editors can detect a person, track their movement across different frames, and intelligently reconstruct the background after the unwanted subject has been removed. This is especially useful when a stranger walks through a travel video, someone appears in the background of a family recording, or an accidental passerby distracts from the main subject. Instead of manually masking hundreds of frames, AI can automate much of the difficult work.
There are two convenient ways to do this: use an AI video removal app directly on your phone, or use an AI-powered video editing tool on a computer. The best choice depends on the length and quality of your footage, how complicated the background is, and how precise you need the final result to be. Below is a detailed guide covering both methods, including the basic workflow, important settings, and practical tips for getting a natural-looking result.
Method 1: Remove Unwanted People on a Phone with an AI App
Using a mobile AI app is usually the quickest option because you can edit a video immediately after recording it. Many AI-powered editing apps provide object-removal or video-eraser features that allow you to select an unwanted person and let AI fill the selected area with reconstructed background content. This method works particularly well for short social-media clips, vacation videos, street recordings, and casual personal footage.
- Open an AI video editing or object-removal app on your smartphone.
- Import the video containing the unwanted person.
- Choose the AI object-removal, video eraser, or remove-object feature.
- Use the brush or selection tool to highlight the unwanted person. Include the entire body whenever possible.
- Preview the AI-generated result and check whether the person has been removed consistently throughout the clip.
- If necessary, adjust the selection area or use additional brush strokes on frames where part of the person remains.
- Export the finished video in the desired resolution and frame rate.
How to Get Better Results on Mobile
Before applying AI removal, trim the video so that you only process the section that actually needs editing. Shorter clips are generally faster to analyze and easier to correct. When selecting the unwanted person, avoid including too much of the surrounding background because an unnecessarily large selection gives the AI more information to reconstruct and can sometimes produce visible distortions.
It is also important to review the entire clip rather than checking only the first few seconds. A person who walks from one side of the frame to another may require the AI to track a changing area. If the application provides automatic tracking, use it. If it does not, you may need to adjust the selection at different points in the video. For simple backgrounds such as walls, roads, grass, or skies, the result can often look surprisingly natural. More complicated backgrounds, such as crowds, fences, moving vehicles, or detailed architecture, may require several attempts.
Method 2: Remove Unwanted People on a Computer with an AI Tool
A computer-based AI video editor is generally a better choice when you need higher quality, longer footage, or more precise control. Desktop tools usually provide a larger preview window, more detailed masking controls, motion tracking, timeline editing, and higher-quality export options. They are particularly useful for professional videos, YouTube content, promotional footage, and recordings where the unwanted person moves significantly through the scene.
- Open an AI-powered video editing tool on your computer.
- Create a new project and import the original video.
- Place the video on the timeline and locate the section containing the unwanted person.
- Select the AI object-removal, generative fill, or video inpainting function.
- Draw a mask over the unwanted person using the available selection or brush tool.
- Enable motion tracking if the person moves during the shot.
- Run the AI removal process and allow the software to reconstruct the background.
- Play the complete edited section and inspect the result frame by frame if necessary.
- Refine the mask, tracking points, or generated background if you notice artifacts.
- Export the final video using settings appropriate for your intended platform.
Why Computer Tools Can Produce Better Results
Desktop software offers more control over difficult footage. For example, if a person crosses behind your main subject, a simple automatic removal may accidentally affect the subject you want to keep. With a computer editor, you can create more precise masks, divide the footage into sections, and correct individual frames or tracking problems. Higher-resolution source footage can also provide the AI with more visual information, which may improve the reconstruction.
Another advantage is that computer tools can handle more advanced workflows. You can duplicate the original video, create separate masks for different unwanted objects, adjust the timing of each mask, and compare several AI-generated versions before exporting. If the background contains repeated patterns, textures, or architectural details, you may also be able to combine AI removal with traditional cloning, masking, or patching techniques for a cleaner result.
What If the AI Removal Looks Unnatural?
AI object removal is powerful, but it is not perfect. Problems usually occur when the unwanted person overlaps the main subject, blocks a large portion of the background, or moves rapidly. You may see blurry areas, duplicated objects, warped lines, flickering textures, or background details that change from frame to frame.
When this happens, try reducing the size of the mask and processing the video in shorter sections. A smaller mask gives the AI more original background information to work with. If the person is moving, make sure the mask follows the subject accurately instead of remaining fixed in one location. You can also compare several generated results and choose the version with the most consistent background.
Phone or Computer: Which Method Should You Choose?
Choose a phone AI app when convenience and speed are your priorities. It is ideal for short clips and straightforward removals where the unwanted person is clearly separated from the main subject. Choose a computer AI tool when the footage is long, high-resolution, professionally produced, or visually complicated. Desktop editing also makes sense when you need precise tracking and detailed corrections.
Tips for a More Professional Result
Whenever possible, start with the highest-quality original video rather than a compressed copy downloaded from a social platform. Avoid repeatedly exporting and re-importing the footage because each compression cycle can reduce detail. Preview the entire result before publishing, especially around the edges of the removed person. Finally, keep the original file untouched so you can return to it if you later discover that another editing approach produces a better result.
Conclusion
AI has made removing unwanted people from videos considerably easier than traditional manual editing. On a phone, an AI removal app can provide a fast solution for short and relatively simple clips. On a computer, a dedicated AI video tool gives you more control over masks, tracking, background reconstruction, and export quality, making it more suitable for complex projects.
Whether you edit on mobile or desktop, the key is to select the unwanted person carefully, use motion tracking when necessary, and review the complete video after AI processing. With good source footage and a suitable AI tool, you can often remove distracting people while preserving the surrounding scene and producing a clean, natural-looking final video.
