Make Split Screen Videos: A Practical Editing Guide

Updated 10 November 2026 · Standard formula, shown below

Yes. You can make a split-screen video by placing two or more clips in the same frame, resizing and positioning them, then syncing their timing and exporting the result. Most desktop and mobile video editors offer a way to do this, either with built-in layouts or by manually cropping and arranging layers.

What a Split-Screen Video Does

A split-screen video shows multiple views at once. The frame might be divided into equal halves for a side-by-side conversation, into a top-and-bottom layout for a comparison, or into several panels for a group call or montage. Each panel can show a separate clip, a different camera angle, or even the same scene at different times.

It is distinct from a simple transition that switches between shots: in split screen, viewers see the clips simultaneously. The technique is useful when the relationship between views matters, such as comparing a before-and-after result, showing a speaker and an interpreter, or presenting two reactions together.

Choose a Layout Before Editing

Decide how many clips you need and what viewers should notice. A two-panel layout is usually easier to read than a crowded grid, especially on a phone. For a comparison, equal-sized panels make the difference between clips clear. For an interview, you might give the main speaker more screen area than the second participant.

Side by side: useful for comparisons, conversations, and simultaneous gameplay or demonstrations.
Top and bottom: can work well for portrait footage or when the subjects have vertical compositions.
Three- or four-panel grid: useful for group scenes, but each clip becomes smaller.
Picture-in-picture: one clip remains large while another appears in a smaller inset; this is related, but not a conventional equal split.

Also choose the final video’s aspect ratio before positioning clips. A vertical frame intended for a phone and a widescreen frame intended for a television have different usable space. If the source clips have different shapes, some cropping or empty space is likely.

How to Make One in a Video Editor

Exact controls differ between programs, but the general workflow is similar. Start a project in the aspect ratio you plan to publish, then add each clip to its own video track or layer. Tracks are stacked, so a clip on an upper track may cover clips beneath it until you resize or crop it.

Import and arrange the clips. Place them on separate tracks and align their start points on the timeline. Trim each clip to the section you want viewers to see.
Set the frame and layout. Choose a split-screen preset if available. Otherwise, use the editor’s crop, scale, position, or transform controls to fit each clip into its panel.
Check the edges. Make sure subjects are not hidden by the split boundary. Add a narrow divider or background if it helps separate panels, but keep it visually subtle.
Synchronize the action. Align a spoken word, clap, movement, or other recognizable event across clips. If the footage was recorded separately, matching the timeline start alone may not synchronize it.
Review and export. Watch the full sequence, check the opening and ending, then export using the frame size and file format appropriate for the destination.

Some editors provide a split-screen template or collage effect that handles the panel arrangement automatically. Templates are quick, but inspect the crop: automatic framing may cut off a face, caption, or important object.

Positioning, Cropping, and Synchronization

Resizing a clip does not always show the whole image. If the editor fills a panel, it may enlarge the footage and crop its sides or top and bottom. This can be helpful when removing distracting edges, but it can also remove context. Use a fit or contain option when you need the entire image visible; depending on the source and panel shapes, that may leave blank bars around it.

Pay particular attention to faces and text. Leave space around a person’s head, avoid placing a split line across a face, and verify that titles remain inside the visible area. Captions should be positioned so they do not overlap another panel or get cut off by the edge of the final frame.

For recorded dialogue, align the clips by their actual audio or a shared event, not just by when recording began. If two clips contain separate audio, decide which track should be heard. You may mute one, keep both at reduced levels, or use a single clean recording; two equally loud, unrelated audio tracks can be confusing.

Common Problems and Fixes

One clip covers the others: resize or crop the upper layer, or change the layer order if the editor’s arrangement permits it.
Black bars or unexpected gaps: check whether the clip is set to fit rather than fill, and confirm the project and source aspect ratios.
Subjects look too small: simplify the layout, crop more tightly, or use fewer panels. A multi-panel design can become unreadable on a small screen.
Audio sounds doubled: mute or lower the unnecessary clip audio, then preview with headphones if possible.
Panels do not stay aligned: check that clips have the intended position and scale throughout the timeline. Some editors allow animated transforms, so a setting may change over time.

Another common misconception is that split screen automatically means the clips are synchronized. It only displays them together; syncing and trimming are separate editing tasks.

Choosing an Editing Method

A built-in layout or template is generally the simplest choice for a quick social video or a basic two-clip comparison. Manual editing gives more control over panel size, cropping, borders, and timing, which is valuable for a polished interview or a carefully composed demonstration. On a phone, look for an editor that supports multiple video layers and position controls; a basic trimming app may not offer those features.

Before committing to a tool, check whether it can export the required aspect ratio and resolution, handle the number of simultaneous clips you need, and preserve the audio choices you make. You do not need a specialized split-screen program if your current editor can place and transform multiple video layers.

Frequently Asked Questions

Can I make a split-screen video on my phone?
Yes, if the editing app supports multiple video layers or a split-screen template. Add the clips, choose a layout, adjust the crop and position, and preview the export on a small screen.

How do I put two videos side by side?
Place each video on a separate track, crop or scale each into one half of the frame, and position them on opposite sides. Align their timing and check that neither clip is obscured.

Can split-screen videos have different aspect ratios?
Yes. The editor can crop, scale, or fit each source into its panel. Cropping fills the panel but may cut off content; fitting preserves the full image but can leave empty space.

How do I sync two videos in split screen?
Line up a shared sound or visual event, such as a clap or a spoken word, on the timeline. Trim or shift one clip until the events match, then check the sync throughout the relevant section.

Why is one video covering the other?
The upper clip may be full-frame or may sit above the other layer. Resize or crop it to its intended panel, and check the track order if the editor uses stacked layers.
