How to Make a Split Screen & Collage Video (Multi-Cam, Reactions)

A single frame can hold more than one story. Split screens and collages let you compare two takes, react to a clip, show four angles at once, or build a before/after — and ExpoCut’s ready-made layouts mean you never have to eyeball the sizing.

What you can build

• Reaction — the source clip big, you small in a corner.
• Comparison / before-after — two tiles, side by side.
• Multi-cam — three or four angles in a grid.
• Stylized split — diamond or mosaic for a designed look.

Step 1 — Pick a layout

1. Add a Collage (or a Layout preset)

   Choose from Grid, Mosaic, Diamond, or Freeform — Freeform lets you place tiles anywhere.

2. Drop a clip into each tile

   Each slot is a layer. Add a video or photo to each one; ExpoCut handles the sizing and position.

3. Fine-tune the fit

   Use each tile’s fit/crop so the important part of every clip is centered in its slot.

Step 2 — Make it move

A static split is fine; a moving one is better. Because every tile is its own layer, you can:

• Start full-screen and transition into the split.
• Keyframe a tile sliding in from the edge.
• Animate a comparison wipe between before and after.

Step 3 — Add labels

Split screens almost always want labels — “Before / After”, names, or camera tags. Drop a title or a lower third on each tile so viewers know what they’re looking at.

Where to go next

• One small inset instead of a full split: picture-in-picture.
• Animate the tiles: keyframes & motion paths.
• Label each panel: text & titles.

Pick a layout, fill the tiles, label them — and you’ve turned one frame into a comparison, a reaction, or a four-angle show.

Frequently asked questions

How do I put two videos side by side?

Add a collage or layout preset, pick a two-up split, and drop a clip into each tile. ExpoCut sizes and positions them for you, so you get a clean side-by-side without manually scaling each video.

Which layout should I use for a reaction video?

A two-tile split (or a small picture-in-picture) works best: the thing you're reacting to in the big tile, you in the smaller one. For multi-cam or comparisons, use a grid; for a stylized look, try mosaic or diamond.

Can I animate the split?

Yes — each tile is a layer, so you can keyframe a tile sliding in, or transition from full screen into a split. Freeform layouts let you place and size each clip exactly where you want.
