iMovie is the free video editor Apple puts on every Mac, iPhone and iPad. It is listed on the App Store at $0 with no in-app purchases (checked 2026, Apple Inc. as seller), it is genuinely good at what it does, and an enormous number of people never need anything else. So the useful version of this comparison is not "which one wins" - it is "what has to be true before paying attention to a second editor makes sense".

Zella is an on-device screen recorder and AI video editor for the same three devices. It is also free to start, with no account and no watermark, and it does several specific things iMovie does not do at all. It also has one ceiling iMovie does not have, and that is where this starts, because it is the strongest argument for staying put.

iMovie or Zella: the quick verdict

  • Stay on iMovie if you trim camera-roll clips into longer movies, you export in 4K, you want zero cost and zero new software, and you do not need captions, screen recording or vertical output.
  • Move to Zella if your videos start as screen recordings, if you want automatic spoken-word captions, if you make vertical shorts, or if you want an editor that cleans up filler and dead air for you.

What iMovie is genuinely better at

It is free, with no ceiling at all. iMovie's Mac App Store description says it can "Edit movies at up to 4K resolution with video from iPhone 6s or later, GoPro, and other Ultra HD cameras on compatible Macs." That 4K export costs nothing, and there is no length limit.

Zella vs iMovie: Which Free Mac Video Editor Wins?

Zella Free caps exports at 2 minutes and 1080p; 4K and unlimited length sit behind the one-time $89 Pro unlock. For a long 4K family video, iMovie is free and Zella is not.

It is already installed. Nothing to download, nothing to evaluate, nothing to trust. That is worth real money in time.

Apple maintains it. It tracks new macOS and iOS releases, it opens on every Apple device you own, and projects hand off between iPhone and Mac.

It is simple on purpose. Magic Movie and storyboards will get a beginner from clips to a finished video faster than any timeline. If someone in your house is making their first video, point them at iMovie.

Where Zella does things iMovie cannot

Screen recording. iMovie is an editor, not a recorder. Zella records your screen, your camera, system audio and your microphone with no time limit, then hands the footage straight to the timeline in the same app. See recording modes. If your content is a demo, a tutorial or a walkthrough, this alone is the whole argument.

Automatic captions. iMovie gives you titles you type. Zella transcribes your spoken audio on device and styles it with 9 caption presets on iOS and 10 on Mac. On iOS 18 and later it can translate those captions into 19 languages, still on device. That is hours of typing removed from every video.

Filler and dead air removal. On iPhone and iPad, Zella runs a verbatim WhisperKit pass that finds your filler words so they can be cut, and it strips silences automatically. iMovie has no equivalent, so you scrub and cut by hand.

Background removal with no green screen. iMovie supports a green screen effect, which means you need a green screen. Zella's background removal works on ordinary footage in an ordinary room.

One-tap vertical. Make Vertical reframes a 16:9 edit to 9:16 with subject tracking, so one recording becomes a landscape video and a reel without re-cutting. See reframe.

An AI assistant that does the work. Zella's AI Assistant exposes 51 actions on iOS and 80 on Mac, in the free tier, with no credits to burn.

The four signs you have outgrown iMovie

  1. You are typing captions by hand. This is the most common one. If you have ever typed out your own words as title cards, an automatic on-device transcription pass will give you that hour back on every video.
  2. You record your screen somewhere else first. If your process starts with QuickTime or a phone recording and then moves to iMovie, you are already using two tools. Zella is one.
  3. You need vertical and horizontal from the same edit. Re-cutting a landscape edit into a reel by hand is the tax iMovie charges. Make Vertical removes it.
  4. You are cutting out your own "um"s. Manual filler removal is the least rewarding work in editing, and it is exactly what an on-device transcript is good for.

If none of those are true, you genuinely do not need to switch. That is not a sales pitch, it is just accurate.

Zella's honest limits

Apple only. No Android, no Windows. Same as iMovie, so this is not a difference between the two, but worth stating.

Free exports are capped. 2 minutes and 1080p. iMovie has no such cap. If length and 4K are what you need and nothing else is, iMovie is the better free option.

It edits what you record. Zella does not generate scenes from a text prompt. Its auto b-roll makes generated cutaway cards with no API key required, which is a different and narrower thing.

The iPhone and iPad app is not on the App Store yet. It is built and native, and the listing is on its way - see the iOS page. The Mac app is available today from download.

Can you use iMovie and Zella together?

Yes, and plenty of people should. iMovie is fine for long-form family video where 4K matters and nothing else does. Zella handles the work videos: the demo, the tutorial, the reel, the captioned clip. They do not fight, because both keep projects as local files and both import ordinary MP4 and MOV.

FAQ

Is iMovie really free? Yes. It is listed at $0 on the App Store for Mac, iPhone and iPad with no in-app purchases (checked 2026).

Can iMovie export 4K for free? Yes, on a compatible Mac. Zella Free tops out at 1080p, and 4K needs the one-time $89 Pro unlock. This is the clearest point in iMovie's favour.

Does iMovie do automatic captions? No. iMovie gives you titles you type yourself. Zella transcribes your speech on device and styles it with caption presets.

Can iMovie record my screen? No. iMovie edits video, it does not capture it. Zella records screen, camera, system audio and microphone with no time limit.

Do I need to pay for Zella to caption a video? No. On-device captions, background removal, the AI Assistant, Beat Sync and Make Vertical are all in the free tier, watermark-free.

Will Zella open my iMovie projects? Not the project files, no. Export from iMovie as MP4 or MOV and import that into Zella, where you get the full timeline, captions, colour and reframe.

The bottom line

iMovie is a good, free, Apple-maintained editor and there is no shame in it being enough. It stops being enough the moment your video starts as a screen recording, needs spoken-word captions, or has to ship vertical as well as wide. That is the line, and it is a clean one.

If you are on that side of it, the Mac app is at download and the iPhone and iPad app is coming to the App Store.
