Video Overlays — Picture-in-Picture & Split-Screen
Layer a second video source directly over your main canvas. Video overlays are perfect for reaction videos, split-screen tutorials, commentary recordings, and multi-camera edits — no software required.
Adding a Video Overlay
- Open the editor with your main video on the timeline
- Click the Video Overlay button in the toolbar
- Choose a source video from your device
- The overlay appears on the canvas, ready to position and style
Positioning & Layout
Each video overlay behaves as an independent layer on the canvas:
- Free Drag: Click and drag directly on the canvas to reposition the overlay at any time
- Scale Control: Use the scale slider to shrink or expand the overlay
- Layout Presets: Apply one-click presets — Picture-in-Picture corners, half-screen splits, or full-cover — all calculated precisely for the current aspect ratio
See Layout Presets for the complete list of available preset positions.
Timeline Integration
Video overlays appear on green-themed tracks on the timeline, clearly separated from main video segments and other overlay types.
- Precise Timing: Drag the overlay track to control exactly when the video starts and ends relative to your project
- Trim Controls: Adjust the overlay's in and out points independently from the main video
Appearance & Effects
The same visual controls available for main video segments apply to overlays:
- Corner Radius & Borders: Round corners or add a colored border for a polished, framed look
- Non-Destructive Crop: Trim any edge of the overlay video without altering the source file — see Video Editing
- Color Adjustments: Apply brightness, contrast, saturation, sharpen, blur, temperature, and tint controls
- Speed: Set an independent playback speed for the overlay, separate from the main clip
Export
When you export your project, all video overlays are composited into the final video using FFmpeg.wasm. Everything runs locally in your browser — your footage is never uploaded to any server.
Common Use Cases
- Reaction videos: Film yourself reacting while the original content plays in the background
- Tutorial overlays: Show a screen recording alongside a talking-head explanation
- Split-screen interviews: Display two participants side by side using the Left Half / Right Half preset
- Commentary: Place a small webcam Picture-in-Picture over gameplay or a screencast
- Multi-camera editing: Combine two angles of the same event into a single frame
Tip: Use the Grid 2×2 layout preset with four video overlays to build a multi-panel mosaic — great for event highlights or multi-angle sports footage.
