About Video Side by Side
The 'Video Side by Side' tool is a completely free online utility that lets you place two video files side by side (horizontal layout) or top-and-bottom (vertical layout) and export them as a single comparison video. This is incredibly useful for before-and-after comparisons, camera quality tests, color grading checks, game settings comparisons, and any scenario where you need to view two videos simultaneously.
Simply drag and drop a video into each slot, choose the layout mode (horizontal or vertical), adjust the gap between videos if desired, and click the merge button. You can also customize output quality by selecting bitrate (2-10 Mbps) and frame rate (24/30/60 fps) to match your needs.
The tool leverages the browser's native Canvas API and MediaRecorder to draw both video streams onto a single canvas in real time, ensuring that your video files are never uploaded to any external server. Your privacy is fully protected while you create professional-quality comparison videos instantly.
How to use Video Side by Side
- Drag and drop the first video file (left or top) into the first drop zone.
- Drag and drop the second video file (right or bottom) into the second drop zone.
- Select the layout (horizontal or vertical), adjust the gap size, and set the background color.
- Choose your output quality: bitrate (2-10 Mbps) and frame rate (24/30/60 fps).
- Select audio option (both, video 1 only, video 2 only, or mute) and click 'Merge & Save' to download.
