Split Screen Video Editor

A split screen video editor lets you show two or more clips in the same frame at the same time. As a split screen video maker it works straight from the browser: upload your videos, drop them onto the canvas, drag each one into a side by side, top and bottom, or grid layout, line up the timing, then export a single MP4. This side by side video maker is free to use, with no watermark on the dedicated tool.

How the split screen editor works

A split screen video puts two or more clips in the same frame so they play at once. In EchoWave each clip you upload becomes its own layer on the canvas, with its own position, size and place on the timeline. To build a side by side video you add two videos, shrink each one to fill half the frame, then drag them left and right until they meet in the middle. Because every clip is independent, you can crop one to hide black bars, scale another up to match it, and nudge either clip earlier or later on the timeline so a reaction lands on the right beat.

The layout is entirely up to you. Snap two clips to a clean 50/50 vertical divide, stack them top and bottom for a phone screen, or drop four clips into a two by two grid. You can also overlap a smaller clip in a corner for a picture in picture look, which is the same technique as a true video overlay. Nothing is locked to a fixed template, so a comparison, a duet and a four-way reaction grid are all built the same way.

Real ways people use split screen video

Reactions and duets. Put a reaction camera next to the clip being watched, the format that powers most TikTok and Instagram reaction content. A vertical top and bottom split is the usual choice here so both faces stay large on a phone.

Before and after comparisons. Show a workout, a renovation, a haircut or an edit on the left and the result on the right. A side by side video comparison makes the change obvious in a single glance, which is why this layout performs well for product demos and tutorials when you want to compare two clips directly.

Gaming and tutorials. Place gameplay or a screen recording on one side and a webcam or talking head on the other. The viewer follows the action and your commentary at the same time without cutting back and forth.

PMV and music edits. Split screen PMV is a staple of the format: a PMV (picture music video) splices two or more clips synced to a track across the frame. Line each clip up to the beat on the timeline and the split screen layout does the rest.

Interviews and panels. Stack two webcam recordings side by side to fake a single shot, useful for remote podcasts and Q and A clips when you only have separate exports of each speaker.

Supported formats and export

You can upload MP4, MOV, WebM, AVI, MKV and most other common video files. Clips with different resolutions, frame rates or even orientations can sit in the same project, because each one is scaled and positioned on the canvas independently. EchoWave exports a single MP4 with H.264 video and AAC audio, the combination that plays everywhere and uploads cleanly to every social platform.

Set the canvas to match where the video is going before you export: 9:16 (1080 by 1920) for TikTok, Reels and Shorts, 1:1 (1080 by 1080) for square feed posts, and 16:9 (1920 by 1080) for YouTube and landscape players. Picking the aspect ratio first saves you from re-cropping each clip later.

How many videos can you combine?

Two is the most common split, but you are not limited to two. Add a third clip for a triptych, or a fourth for a two by two grid, and arrange them however the story needs. Every clip keeps its own audio, so you can mute one source, keep another, or replace the lot with a single music track. If you want a structured photo and clip mosaic instead of free placement, the video collage tool gives you ready-made grids.

Tips for a clean result

Match the look of both clips so the split feels intentional: crop each one to the same aspect before placing it, and keep a consistent gap or zero gap down the divide rather than an uneven seam. If one clip is darker or shakier, fix it before you line them up. For comparison videos, sync the starting frames so the action begins together; for reactions, offset the timeline so your response lands a beat after the moment. Keep important subjects away from the divide so nothing critical gets clipped, and add a short title with the text tool to label each side when the contrast is not obvious.

A free split screen video maker in your browser

EchoWave is a free split screen video maker you can make split screen video online with, on Chrome, Edge, Firefox or Safari and on Windows, macOS, Chromebook, iPhone or Android, without installing anything. There is no split screen video app to download: the side by side video maker loads as a web page, and exports from the dedicated tool carry no watermark. Your clips upload to your own EchoWave project for processing rather than being shared publicly, and you can delete a project once you have downloaded the finished MP4.
