How to Add a Subtitle in iMovie: Step-by-Step Guide

Adding subtitles in iMovie is possible, but the process is mostly manual. On Mac, iPhone, and iPad, you can use iMovie's Titles feature to place subtitle-style text over your video and adjust when it appears. If you need automatic subtitles, you'll need a separate AI subtitle tool.

How to add a subtitle in iMovie on Mac

iMovie does not use a dedicated subtitle track in the same way some professional video editors do. Instead, you add subtitle text as titles placed over your video clips. This works well for short videos or projects with only a few lines of dialogue, but adding subtitles to a long conversation can take time.

Step-by-step: Add subtitles in iMovie on Mac

Step 1: Import your video and select a title style

Open iMovie and create or open the project containing your video. Import the video if it is not already in your media library, then drag the clip to the timeline. Select the Titles option and choose a simple title style that works with subtitles. A basic style is usually easier to read than a decorative one.

Step 2: Enter your subtitle text and adjust its timing

Place the title in the part of the timeline where the dialog begins. Click on the text area in the preview window and replace the sample text with the words you want to show. Then you move the title along the timeline and change the duration so that the subtitle appears and disappears at the right times in the conversation.

Step 3: Customize the subtitle appearance and repeat the remaining dialogue

Change the font, size, alignment, and other text settings that are available, so the subtitles are still readable against the video. Verify the timing in the clip's preview, then add another title for the following line of dialog. And keep repeating till you have covered the whole conversation.

For a short video, this method is manageable. A longer interview, tutorial, or talking-head video can require many individual title elements, so checking every line becomes an important part of the editing process.

How to add subtitles in iMovie on iPhone and iPad

On iPhone and iPad, you can use iMovie's Titles feature to create subtitle-style text. When a single video clip contains multiple lines of dialogue, first split the clip at the points where each subtitle should change. You can then add a title to each section and use Full Clip Duration to keep the title visible for the entire corresponding clip.

• Select and split the video clip: Open your iMovie project and tap the video clip containing the dialogue. Move the playhead to the point where the first subtitle should end, then tap Split. Repeat this at each dialogue change, so each section of the clip corresponds to a subtitle.

• Add a title to the first section: Select the first split clip, tap Titles, and choose a readable style. Tap the text in the preview, replace the sample text with the corresponding subtitle, and adjust its position if needed.

• Use Full Clip Duration: With the title selected, choose Full Clip Duration so the subtitle remains visible for the entire selected clip. Because the clip has already been split according to the dialogue, the title will stay on screen for the appropriate section.

• Add subtitles to the remaining sections: Select each split clip, add a Title, and replace the sample text with the next subtitle. Set each title to Full Clip Duration so it matches the timing of that clip.

• Check the timing and readability: Preview the project from the beginning and make sure each subtitle appears with the correct dialogue and disappears when the next subtitle begins. Keep the text large and clear enough to read against the video background.

Can you add automatic subtitles in iMovie?

iMovie does not have a built-in feature for automatically generating subtitles from spoken dialogue. Its Titles feature lets you add subtitle-style text, but you need to type each line yourself and adjust its timing on the timeline. This is manageable for short videos, but longer videos can take much more time because every line has to be entered and synchronized with the speech.

If you want to avoid that manual work, an AI subtitle generator can transcribe the video's speech and create timed subtitles automatically. This gives you a faster way to prepare subtitles before bringing the finished video back into your editing workflow.

Key features

Step 2: Generate and customize

Choose the subtitle function and let Vmake process the dialogue. Review the generated text, correct any mistakes, and make any necessary adjustments before moving to export.

iMovie vs. Vmake Labs for adding subtitles

Both tools can help you add subtitles to a video, but they handle the process differently. Here's a quick comparison of their subtitle features.

iMovie works well when you only need to add a few subtitle lines and want to control their placement and timing yourself. Vmake Labs is more suitable when the video contains a lot of dialogue and you want the subtitles generated from the audio rather than entered line by line.

Conclusion

Adding subtitles in iMovie is straightforward when you only have a few lines of dialogue. On Mac, iPhone, and iPad, you can use Titles to enter the text, adjust its timing, and customize how it appears. However, iMovie does not automatically transcribe spoken dialogue, so longer videos require more manual work. If you want a faster option, Vmake Labs can generate synchronized subtitles from your exported video and let you review them before export. You can also use its auto generated captions when you need captions without adding each line yourself.
