Removing video backgrounds is increasingly common for creating cleaner, more professional-looking content. There are a few ways to approach this depending on your needs:

1. Online Background Removal Tools

• Unscreen: An online tool specialized in video background removal. You can upload a video, and it automatically removes the background, though free versions may have limitations like watermarks or length restrictions.
• Kapwing: This versatile editor has a background removal feature that uses AI to separate subjects from the background in a few clicks.
• Runway: Known for advanced AI editing, Runway offers background removal in its suite of tools. It’s a bit more powerful and can handle complex video scenes.

2. Desktop Software for Video Editing

• Adobe Premiere Pro + After Effects: With Premiere Pro, you can use the Ultra Key feature to key out a green screen background. For non-green screen, After Effects with the Roto Brush tool can isolate a subject in video.
• Final Cut Pro X: This software offers a background removal option for green screens and also has plugins available for non-green screen removal.
• DaVinci Resolve: With its Fusion tab, DaVinci Resolve has tools for chroma keying and background removal, though it may require more manual editing for complex backgrounds.

3. AI-Powered Apps

• Veed.io: A web-based platform with AI background removal, allowing you to make quick adjustments to video backgrounds.
• Remove.bg (for images) and PixCut: While these are mainly for images, they can be a workaround by extracting frames from a video, using these tools, and then recomposing in a video editor.

4. Custom Solutions

For custom needs or large projects, hiring a video editor or using custom software solutions that leverage AI and machine learning can provide more control.
