Put two videos side by side
Play two videos next to each other in a single clip — for comparisons, reactions, duets, or before-and-after footage. The editor opens with the side-by-side layout ready: drop a video in each half, line them up, and export one MP4. Both clips keep their own sound, and everything runs in your browser, so nothing is uploaded anywhere.
How it works
- 1
Add your two videos
Click each half of the frame to pick a video, or just drag both files in at once. Photos work too, if one side is a still.
- 2
Line them up
Drag inside a panel to reframe it, drag the centre border to give one side more room, and trim each clip on the timeline so the moments match.
- 3
Balance the sound
Each video keeps its own audio. Use the volume slider per clip — or mute one side — so the export sounds the way you want.
- 4
Export as MP4
Pick 9:16 for TikTok and Reels, 16:9 for YouTube, or square for feeds, then export. Free, no watermark, no account.
Common questions
- Do both videos play at the same time?
- Yes — both halves play together. If one clip is shorter you can loop it to fill, or trim the longer one to match.
- Can I make a duet or reaction video?
- Yes. Put the original clip on one side and your reaction or duet part on the other; both keep their sound, so lower one side’s volume if they talk over each other. For a vertical reaction with the original on top and you underneath, use the Reaction starter (linked below): it opens a 9:16 frame with the two clips stacked.
- Can I do top-and-bottom instead of left-and-right?
- Yes. Switch to the stacked layout in the editor — there are 150 layouts, including vertical splits, grids and picture-in-picture.
- Is my footage uploaded?
- No. Editing and export run entirely in your browser; your files never leave your device.
