How do I remove a background color from a video online?

Upload your video to Green Screen Remover, pick the background color to remove (green, blue, white, or any solid color), adjust the chroma key settings if needed, and click process. The tool automatically removes the background and exports a transparent WebM video with alpha channel.

Is Green Screen Remover free to use?

Yes! The free tier allows you to process 1 video per day. Upgrade to Pro for 50 videos per month, no watermarks, and priority processing.

What video format does it export?

Videos are exported as WebM format with alpha channel (transparency). You can choose between VP8 or VP9 codec. VP8 is recommended for Unity games.

Can I use this for Unity or Unreal Engine?

Absolutely! The tool exports transparent WebM videos that work perfectly in Unity and Unreal Engine. VP8 codec is optimized for Unity compatibility.

What is the maximum video file size?

Free users can upload videos up to 50 MB. Starter and Pro plans support videos up to 500 MB with longer durations and higher resolutions.

How is this different from other background removers?

Green Screen Remover specializes in video (not just images) and works with any solid background color — green, blue, white, and more. It uses AI chroma-key processing to output transparent WebM files with alpha channels — the format game engines like Unity and Unreal Engine need. Most competitors only handle still images or green screens.

What Is Chroma Keying?

Chroma keying (also called color keying) is the process of removing a specific color from a video and replacing it with transparency or another background. It is the technique behind every weather forecast, movie VFX shot, and YouTube green screen video.

Traditionally, chroma keying required professional software like After Effects, Nuke, or DaVinci Resolve. Green Screen Remover brings the same capability to your browser — no download, no timeline, no learning curve.

How It Works

Chroma key your video in three simple steps.

Upload Your Video

Drag and drop any video file. Supports MP4, MOV, WebM, AVI, and MKV up to 200MB.

Pick the Key Color

Select the background color to remove. Adjust the tolerance slider to fine-tune the key for clean edges.

Download Transparent Video

Export as WebM with alpha channel (VP8 or VP9 codec). Ready for editing, compositing, or game development.

Tips for a Better Chroma Key

Even Lighting

Light your background evenly to avoid shadows and hot spots. Uneven lighting makes the background appear as multiple shades, which complicates the key.

Subject Distance

Keep your subject at least 6 feet from the backdrop to minimize color spill — the reflection of the background color onto your subject.

Avoid Matching Colors

Ensure your subject does not wear or contain the same color as the background. Green shirt + green screen = invisible torso.

Adjust Tolerance

Start with a low tolerance and increase until the background is fully removed. Too high a tolerance will eat into your subject.
