How to add subtitles in iMovie

iMovie adds titles: text you type and place on a clip yourself. Apple's iMovie guides for Mac and iPhone, read on 3 November 2026, have no page on automatic captions or on importing a subtitle file. Below are Apple's own title steps for typing subtitles by hand, then the faster way: export the movie, drop it here, and Burncaps burns animated word-by-word captions into it from the speech, free. The video is never uploaded to us.

MP4 or MOV, or audio for subtitles.

The video never leaves your browser. On a computer, the sound is heard on your own device unless you choose our speech service; on a phone, it goes to our speech service unless you keep it on the phone. The service gets short pieces of sound, never the picture.

Type subtitles into iMovie, with titles

In iMovie a subtitle is a title: one line of text you type, place over a clip and stretch to the length of the words. These are Apple's steps.

How to add subtitles in iMovie on a Mac

  1. Open your movie in the timeline, then select Titles above the browser.
  2. Browse the title styles, or use the search field to find one by name.
  3. Put the playhead where the line is spoken and double-click the title, or drag the title into the timeline above the clip.
  4. Double-click the placeholder text in the viewer and type the line.
  5. Change the font, colour, size, style or alignment with the font controls above the viewer. The B, I and O buttons make it bold, italic or outlined.
  6. Click Apply.
  7. Drag either edge of the title bar in the timeline to set how long it shows, or type a time in the Duration field of the Clip Information.

Apple notes that the font cannot be changed in some theme and animated titles. Each title is one line you type and time by hand, so a talk needs one for every sentence.

How to add subtitles in iMovie on an iPhone

  1. Open the movie project and tap a video clip in the timeline.
  2. Tap the Titles button, then tap a title.
  3. Tap the sample title in the viewer, tap Edit, type the line and tap Done on the keyboard.
  4. Drag the title to move it, and pinch it to make it bigger or smaller.
  5. For the look, use the Font and Color buttons. Under Style, Lower Third places the title toward the bottom of the screen; under More, turn on Text Shadow or Uppercase.

In Apple's iPhone guide a title belongs to a clip or a photo, which then shows a T in the timeline.

Where these steps come from

Apple's own help: Add titles in iMovie on Mac, Modify titles in iMovie on Mac and Add titles to a movie in iMovie on iPhone, all read on 3 November 2026. Neither the Mac guide nor the iPhone guide had a page on captions, subtitles or subtitle files that day. Apple changes iMovie from time to time, so a button may have moved since.

The faster way: captions made from the speech

Export from iMovie

On a Mac: select the movie, choose File, Share, File, pick the resolution and quality, click Next and Save. On an iPhone: tap the Share button, Share Video, then Save Video for your photo library or Save to Files. These are Apple's steps.

Drop it in Burncaps

Open burncaps.app in your browser and drop the file, or pick it from your phone. It opens in this page and is never uploaded to us. Every word is heard and timed to the voice, and you click any word to correct it.

Pick a style and export

Choose one of 60 styles, change the font, colours, size and place if you like, and export a new MP4 with animated word-by-word captions in the picture, for a video up to ten minutes.

Caption the finished movie

Burned-in captions become part of the picture, so caption the movie once the edit is done: a cut made afterwards cuts the captions with it. On a computer the whole video keeps its own resolution, and an AAC sound track, the usual kind in an MP4, is copied as it was.

For YouTube: subtitles viewers can switch on

If the iMovie video is going to YouTube and you want subtitles that viewers can turn on and off, save an SRT file from Burncaps instead of burning them in, and upload it in YouTube Studio beside the video. Each subtitle is timed to the voice, up to two lines of 42 characters. The YouTube subtitle generator has YouTube's own upload steps.

Where the words go

The video stays in your browser. On a computer, English is heard on your own device unless you choose our speech service, which is also offered for other languages and for recordings over ten minutes; on a phone the sound goes to our speech service unless you keep it on the phone. The service gets short pieces of sound, never the picture, and passes them to Microsoft's speech recognition in the EU, which by Microsoft's terms for the service stores none of it. The script's text leaves your device only if you type names to spell right, choose a translation or choose Clips (it then goes to our AI); ticking Keep everything on this device stops that. Transcribe a video without uploading it shows how to check every request yourself.

Questions, answered plainly

Does iMovie have auto captions?

Apple's iMovie User Guides for Mac and for iPhone, read on 3 November 2026, have no page on automatic captions: they describe titles, which you type and place yourself. For captions made from the speech, export the movie from iMovie and burn them in with Burncaps, free for 2 videos every 30 days with no watermark.

Can iMovie import an SRT file?

Apple's iMovie guides for Mac and for iPhone, read on 3 November 2026, have no page on importing a subtitle or caption file. For an iMovie video on YouTube, upload an SRT file in YouTube Studio beside the video. For captions in the picture, drop the exported movie on Burncaps, which makes them from the speech.

How do I add subtitles in iMovie on a Mac?

Open your movie in the timeline and select Titles above the browser. Put the playhead where the line is spoken and double-click a title, or drag it above the clip. Double-click the placeholder text in the viewer, type the line and click Apply, then drag the title's edges in the timeline to set how long it shows. Repeat for every line. These are Apple's steps, read on 3 November 2026.

How do I add subtitles in iMovie on an iPhone?

How do I add captions to an iMovie video automatically?

Export the movie from iMovie (File, Share, File on a Mac; Share, Share Video on an iPhone), then drop the file on burncaps.app. Burncaps hears the speech in your browser, times every word to the voice and burns animated word-by-word captions into a new MP4, for a video up to ten minutes. Correct any word with a click before you export.

Can I make iMovie subtitles bigger, or put them at the bottom?

In iMovie on a Mac, the Size menu beside the Font menu changes the text size; on an iPhone, pinch the title, and Lower Third under Style places it toward the bottom (Apple's guides). In Burncaps, the Size control goes from 55% to 160% of each style's own size, and you drag the captions wherever you want them.

Is my video uploaded?

No. Burncaps opens the video in your browser and never receives it. On a computer, the sound is heard on your own device unless you choose our speech service; on a phone it goes to our speech service unless you keep it on the phone (short pieces of sound, never the picture, to Microsoft's speech recognition in the EU, which by Microsoft's terms for the service stores none of it).
