Frequently Asked Questions
Everything you need to know about AI Video Background Remover and local WebAssembly processing.
Do I need a green screen physical backdrop to use this tool?
No physical green screen is needed! Our AI segmentation engine analyzes video pixels directly in your browser to separate foreground subjects from backgrounds automatically.
Can I replace the background with my own custom image?
Yes! You can upload any JPEG or PNG photo (like an executive office, beach, modern studio, or tech background) and the tool will composite you directly in front of it.
What output formats are supported?
You can export high-quality WebM video with the new background, green screen, or transparent alpha channel.
Are my video files uploaded to any external server?
Zero bytes ever leave your device. All video processing and background segmentation run locally in your web browser memory.
