## Overview

Easily remove solid color backgrounds from your videos using our online Chroma Key tool. Upload your video, select your background color—such as green, blue, black, white, or a custom hue—and adjust the similarity and edge blending settings to export your video with a transparent alpha channel in WebM, MOV, or MKV format.

## Inputs

- **Video File** (file): Select a video file to remove background
- **Key Color (Background Color)** (select)
- **Custom Color** (color): Select custom background color to remove (when Key Color is set to Custom)
- **Similarity** (range): Color matching tolerance (0-1). Higher values remove more similar colors.
- **Blend** (range): Edge feathering (0-1). Higher values create softer edges.
- **Output Format** (select)

## When to use

- When you need to isolate a subject filmed against a green screen or blue screen for video compositing.
- When you want to remove solid black or white backgrounds from motion graphics or animations to make them transparent.
- When preparing video assets with alpha channels for web players, video editors, or presentation software.

## How it works

- Upload your video file (up to 100MB) containing a solid color background.
- Select the key color to remove, choosing from presets like green, blue, black, white, or picking a custom color.
- Fine-tune the similarity slider to adjust color tolerance and the blend slider to feather the edges.
- Choose your preferred output format (WebM, MOV, or MKV) and process the video to download the result with a transparent background.

## Use cases

- Removing green screen backgrounds from spokesperson videos to overlay them onto custom presentation slides.
- Isolating animated icons or lower thirds rendered on a solid black background for overlaying on video timelines.
- Extracting product demonstrations filmed against a solid white backdrop to place them on dynamic web pages.

## Frequently asked questions

### What video formats can I export with transparency?

You can export your transparent video in WebM, MOV (QuickTime Animation), or MKV formats, which support alpha channels.

### How do I remove a background color that is not green or blue?

Select the 'Custom Color' option in the Key Color dropdown and use the color picker to target your specific background color.

### What do the Similarity and Blend settings do?

Similarity controls the color matching tolerance to remove similar shades, while Blend feathers the edges to create a smoother transition.

### Is there a file size limit for the uploaded video?

Yes, the tool supports video uploads up to 100 MB.

### Why is my exported video background black instead of transparent?

Ensure your video player supports alpha channels, or import the exported WebM, MOV, or MKV file into a video editor to overlay it on another track.
