Mac Screen Recording to MP4: How to Save or Convert

A Mac screen recording saves as a .mov file. To get an MP4, you can rename the file (if it uses H.264) or export it from iMovie. Both are free and from Apple. Or you can record with Quibble, which makes an MP4 when you finish editing.

QuickTime Player cannot do this for you. Apple says it "doesn't export movies as MP4 videos." So you need one of the steps below.

Why your recording is a .mov

When you record with the Screenshot toolbar (Shift-Command-5) or QuickTime Player, Apple saves a .mov file named "Screen Recording [date] at [time].mov." Apple says that on macOS Tahoe 26 or later, the codec is H.264 when the capture format is SDR (Most Compatible) and HEVC when it is HDR.

The codec matters, because it decides which method below works.

Method 1: Rename the file (H.264 only)

This changes the file type. It does not re-encode the video, so the resolution and file size stay the same. Apple's steps:

1. In Finder, select the .mov file.
2. Choose File > Get Info. Under More Info, check that one of the codecs is H.264. If it is not, use Method 2.
3. Optional: Control-click the file and choose Duplicate, so you keep the original.
4. Control-click the file and choose Rename.
5. Change the ending from "mov" to "mp4" and press Return.
6. When the window appears, click Use .mp4.

If the MP4 will not upload after renaming, use Method 2.

Method 2: Export from iMovie (any codec)

iMovie is free on Mac. Apple recommends it when the codec is not H.264, or when you want to change the size or quality. Apple's steps:

1. In iMovie, click Create New in Projects view, then choose Movie.
2. Click Import at the top of the window and find your .mov file.
3. Select the file and click Import Selected.
4. Select the file in the browser, then choose Edit > Add to Movie (or press E).
5. Click Share, then choose Export File.
6. Optional: to make a smaller file, use the Quality menu (Medium or Low) or set a lower resolution.
7. Click Next, choose where to save, and click Save.

This takes more steps than renaming, but it works for any recording.

Method 3: Record in Quibble and get an MP4

Quibble records your Mac screen and opens an editor when you stop. You do not convert anything.

1. Press ⌥⌘R to start recording.
2. Press ⌥⌘R again to stop. The editor opens.
3. Edit if you want: cut parts, fix captions, move zooms.
4. Press Done Editing. Quibble makes the finished MP4.

If you edit again and press Done Editing again, the new MP4 replaces the old one.

Quibble also adds captions (English or Korean) a few seconds after you stop, zooms on your clicks, and lets you hold ⌘ while you draw to highlight with a circle or box. These are optional. You can just stop and press Done Editing.

Recording and editing are free. You need a license to save the finished video: $7.99 per month, $79 per year, or $129 once.

If you want to keep editing in CapCut, Send to CapCut makes a folder with your video and SRT captions. See our guide to importing a screen recording into CapCut.

Which method should you use?

If you only record now and then, the free Apple methods are enough. Quibble helps if you make recordings often and want MP4 plus captions and zooms without extra steps.

What Quibble does not do

• It runs only on Macs with Apple silicon, with macOS 15 or later.
• It does not convert a .mov you already have. It makes an MP4 from recordings made in Quibble.
• It has no cloud upload or share links, and no Windows version. You share the file yourself.

Apple lists it as a method when the file uses H.264. Check File > Get Info first, and duplicate the file so you keep the original.

How do I convert .mov to MP4 on Mac for free?

Rename the file if it uses H.264, or import it into iMovie and use Share > Export File. Both come from Apple.

Does Quibble save an MP4?

Yes. When you press Done Editing, Quibble makes an MP4. Saving the finished video needs a license.

How do I make the file smaller?
