# Swap your green screen for an animated background

> In Tella, add a Tella Motion clip and ask the Tella Agent to place your green screen footage in it, from the chat or your Media Library. The Color key in Tella Motion turns the green transparent, and a Matte choker cleans up the edge. Then describe the background, and the agent builds it behind you as editable layers.

## Questions people ask

### Can Claude or ChatGPT key out my green screen in Tella?

Yes. Connect [Claude](https://claude.ai/directory/tella) or [ChatGPT](https://chatgpt.com/plugins/plugin_asdk_app_6a7026f78434819186579d93d20ab38b?open_in_app) to Tella's [MCP server](https://www.tella.com/mcp) and it gets the same Tella Motion tools as the Tella Agent. It can place your video, apply the Color key and build the background.

### My footage has a blue screen instead of green. Does it still work?

Yes. The Color key in Tella Motion works with any color, and green is the default. Tell the Tella Agent your backdrop is blue, or give it the exact color.

### Do I need a green screen to remove my background in Tella?

No. The Color key in Tella is for footage shot against a solid colored backdrop. If you recorded in a normal room, use Cut out under Layout to remove the background behind you.
