How do you join two split clips in iMovie?
Can you join independent clips together on iMovie?
These common questions appear frequently on platforms like Quora. iMovie, Apple’s native editor for macOS and iOS, offers a wide range of tools that empower users to unlock their creative potential. One of the most frequently requested features is the ability to merge clips—known in the software as the “Join Clips” function. If you’re wondering how to join clips in iMovie, this guide walks you through every step, explains when the feature is unavailable, and presents practical alternatives.
Part 1. How to Join Clips into One in iMovie
In iMovie, the Join Clips tool re‑connects two segments that were previously split. This is especially useful if you accidentally split a clip and want to restore it as a single piece. Below is a clear, step‑by‑step walkthrough for both macOS and iOS.
How to Join Clips Using iMovie on Mac
Step 1: Launch iMovie, start a new project, and import the video you wish to merge into the event browser.
Step 2: Drag the imported clip onto the timeline. Here you can perform any necessary edits, including splitting.
Step 3: After splitting the clip, hold Shift and click to select the resulting segments you want to join. Ensure all desired clips are highlighted.
Step 4: From the menu bar, choose Modify > Join Clips. The selected segments will merge into a single clip.
Note: The Join Clips option may appear grayed out if the segments were not originally split within iMovie. It is not intended for merging separate files.
How to Join Clips in iMovie on iPad/iPhone
iOS versions of iMovie lack a dedicated Join Clips command. However, you can still combine multiple clips by following these steps:
Step 1: Open iMovie and tap the + icon to create a new project. Set the project name and aspect ratio as desired.
Step 2: Tap Add Media in the upper‑right corner to load your clips. You can trim each clip by dragging the yellow handles before adding it to the timeline.
Once all clips are loaded, drag them onto the timeline in the order you prefer. Tap Done to export the concatenated sequence as a single video.
Part 2. Why Can’t I Join Clips in iMovie?
The Join Clips function is specifically designed to re‑connect segments that were split inside iMovie. It will be unavailable if you try to merge independent files. To combine separate videos, simply import them into the same project, arrange them sequentially, and then export the timeline as a single file.
Export by tapping the Share icon, selecting File, and following the on‑screen prompts. The resulting video can then be re‑imported into a new project if further editing is needed.
Supported input formats include MP4, MOV, MPEG, AVCHD, HDV1080i, and DV. Ensure your files match one of these types to avoid compatibility issues.
Additional Merging Options in iMovie
Beyond simple concatenation, iMovie lets you create split‑screen or picture‑in‑picture (PiP) layouts. Split‑screen is ideal for before‑and‑after comparisons, while PiP allows one clip to appear over another. Adjust the inset size by dragging its corner handles.

What formats does iMovie support for import and merging?
iMovie accepts MP4, MOV, MPEG, AVCHD, HDV1080i, and DV files.
Why can’t I re‑join clips that were originally part of the same video?
