Merge Videos combines multiple clips into a single video. All inputs are normalized to the same resolution and frame rate (30fps), and the output duration equals the sum of all clips minus transition overlap. Supports 28 transition effects including fade, dissolve, slide, wipe, smooth, circle, and zoom.

​
When to use

  • Compilation reels from multiple clips
  • Story sequences with smooth transitions
  • A/B roll assembly for marketing videos
  • Social media montages
Common patterns: upload_video + upload_video → merge_videos, or upload_video x3 → merge_videos → google_drive_export.

​
Inputs

​
video
required
The clips to merge, in order. Required, accepts multiple. A single connection works when it carries a list of clips (a fan-out’s results) — you’ll see a reminder to check the item count. Connect two or more for explicit ordering.

​
Outputs

​
video
The merged video.

​
