## Overview

The Video Overlay tool allows you to easily merge two videos by placing one on top of another in a customizable picture-in-picture (PiP) layout. Simply upload your background base video and overlay video, then adjust the position, scale, and opacity to create professional composite videos in MP4, WebM, or MKV formats.

## Inputs

- **Base Video** (file): Select the base (background) video
- **Overlay Video** (file): Select the overlay video to place on top
- **Position** (select)
- **Overlay Scale (%)** (range): Size of overlay video relative to base (5-100%)
- **Opacity** (range): Overlay opacity (0.1 = transparent, 1 = opaque)
- **Output Format** (select)

## When to use

- When creating reaction videos or gameplay commentary where you need a smaller facecam video overlaid on the main footage.
- When adding a sign language interpreter video to the corner of an educational or public announcement video.
- When placing a semi-transparent watermark, animated logo, or secondary B-roll clip over a primary video track.

## How it works

- Upload your primary background video as the Base Video and the secondary clip as the Overlay Video.
- Select the overlay position from options like top-right, bottom-left, or center, and adjust the scale percentage to resize the overlay.
- Set the opacity level to make the overlay semi-transparent if needed, and choose your preferred output format (MP4, WebM, or MKV).
- Process the video to render the composite layers and download the final picture-in-picture file.

## Use cases

- Creating picture-in-picture gameplay videos with a facecam overlay in the top-right corner.
- Adding a semi-transparent corporate logo or watermark video over promotional footage.
- Embedding a sign language translation video at the bottom-right of an instructional lecture.
