Frequently Asked Questions
- How does green screen removal work?
- The chromakey filter identifies pixels matching your chosen key color and makes them transparent. Adjust the similarity slider to control how strictly colors are matched.
- Can I remove a blue screen instead of green?
- Yes, click the key color picker and select the blue you want to remove. Any solid color background can be removed.
- What if the edges look rough?
- Increase the Edge Blend slider for softer transitions between the subject and the removed background. You may also need to fine-tune the Similarity slider.
- Is this chromakey tool free?
- Yes, completely free with no watermark or limits. All processing happens in your browser using FFmpeg WebAssembly.
