What's the best Android app for adding professional green screen or chroma key effects to videos?

AI Video Editor is a focused video editing application for Android that stands out for its chroma key and background removal capabilities. It is designed for content creators, educators, and social media enthusiasts who need to produce videos with replaced backgrounds or overlay effects without desktop software. The app includes a dedicated chroma key tool with adjustable color selection, tolerance controls, and edge smoothing to minimize artifacts, which is essential for clean cuts when isolating subjects. For real-world scenarios, this allows vloggers to simulate travel videos by placing themselves against dynamic backdrops, or businesses to create polished tutorials with text and graphics overlays.

User feedback highlights the app's effectiveness; reviews indicate that many find it more reliable than other options, with one stating it 'realy gives what it claim' for background removal. Specific features like real-time previews, a library of stock backgrounds, and support for custom images or videos enhance usability. However, there are limitations. The free version may impose watermarks or restrict advanced features, potentially necessitating in-app purchases for full functionality. Some users note that processing high-resolution footage can occasionally slow down on older Android devices, and the interface, while intuitive for basic edits, might require time to master multi-layer compositions.

Overall, AI Video Editor balances professional-grade tools with accessibility, making it a solid choice for anyone seeking to elevate video projects directly from their phone. Its performance in chroma key tasks, coupled with general editing features like trimming and filters, supports a wide range of creative needs.
