How to Make a Split-Screen / Reaction Reel

Published June 9, 2026 · 4 min read · By DownloadReels

Split-screen and reaction reels are some of the most-shared formats on Instagram and TikTok — before/after, duets, and picture-in-picture reactions. The free Reel Maker builds them in seconds: drop in two clips and choose a top/bottom or side-by-side split, or a picture-in-picture reaction, then add captions and music. No watermark, no signup, nothing stored. Here’s how.

1
Add two clips

Upload two videos, or paste links to download reels you want to combine.

2
Pick a layout

Choose Split top/bottom, Side by side, or Reaction (picture-in-picture).

3
Caption & add music

Add AI auto-captions and a music track to tie it together.

4
Export

Download your split-screen reel with no watermark.

Split-screen vs picture-in-picture

A split-screen puts both videos at equal size — top/bottom is ideal for 9:16 before/after and duets, while side-by-side suits comparisons. Picture-in-picture keeps one video full-frame with a smaller clip in the corner — perfect for reaction reels where your webcam sits over the content you’re reacting to. The Reel Maker offers all of these as one-tap templates.

Make it pop

Add auto-captions so viewers follow along on mute, drop a trending music track underneath, and pick a bold cover frame. Need the source clips first? Use our free downloaders to download reels and combine them. It’s all free, with nothing stored.

Tip: For reaction reels, keep your picture-in-picture window in a corner that doesn’t cover the key action in the main clip.
