[Descript](https://cotovan.com/descript) offers two different ways to remove your video background — the traditional Chroma Key effect and a newer AI-powered Green Screen filter. Each has its strengths, and in this tutorial I compare both methods side by side.

**Watch the full tutorial:**

## Method 1: Chroma Key

Chroma Key is the classic approach. It works by selecting a specific colour in your video (typically green) and making it transparent. To use it:

1. Select your video clip on the canvas or timeline
2. In the right-hand Properties panel, go to **Visual** **Effects**
3. Click **+** and add **Chroma Key**
4. Select the colour to remove (defaults to green but might need adjusting with the color picker)

Chroma Key applied — the green screen background is replaced with transparency

The Chroma Key panel gives you four controls to fine-tune the result:

- **Color** — Pick the exact background colour to key out
- **Similarity** — How much variation from the selected colour to include (higher = more aggressive removal)
- **Smoothness** — Softens the edge between subject and removed background
- **Spill** — Removes colour spillover from the background onto your subject

Fine-tune the Chroma Key with Similarity (45%), Smoothness (10%), and Spill (10%) sliders

**Pros:** Precise control, works well with proper green screen setups and even green surface.  
**Cons:** Requires an actual green/blue screen backdrop. Poor lighting will produce messy edges and uneven removal.

## Method 2: AI Green Screen

The AI Green Screen effect uses machine learning to detect and separate the subject from the background — no physical green screen required. Simply add the **Green Screen** effect from the Effects panel and Descript handles the rest.

Descript offers two background removal methods — the AI-based Green Screen and the traditional Chroma Key

**Pros:** No green screen needed, works with any background, quick to apply.  
**Cons:** Edge detection can be imperfect, especially with complex hair or fast movement. Less manual control than Chroma Key. If you have a microphone in front of you, it might poke a hole where the microphone is, right in your torso 😄

## Which Should You Use?

If you filmed with a green screen, use **Chroma Key** — it gives you more control and cleaner edges. If you didn't use a green screen but still want to remove the background, the **AI Green Screen** is your best option. You can even stack both effects if needed.
