Subtitles vs Captions: Which One to Add in iMovie?
It is quite common to use the terms subtitles and captions interchangeably. Both of them serve the common purpose of increasing a video’s accessibility. However, there are some significant differences.
- Subtitles are meant to translate or transcribe the spoken dialogue in a visual content. They are useful for viewers who might not even speak the original language of the video. Yet, subtitles have the assumption that the audience can hear and process all of the other audio information, such as musical cues.
- Captions, on the other hand, are a more complete audio representation of whatever is happening in the visual content. They include the spoken words as well as non-verbal sounds. Detailed captions can also include environmental noises, such as (whistling), and tone of voice.
Adding both subtitles and captions in iMovie is only possible through the manual process, so you can add both of them. However, remember that this manual process can be long and complex, so it is always better to choose a reliable video caption generator that can complete the entire process within a few minutes.

How to Add Subtitles to a Video in iMovie? (Step-by-Step Guide)
Here are five steps you have to follow to add subtitles to a video in iMovie:
1. Open iMovie and create a new project.

2. Add the video to which you want to add the subtitle.

3. Click on the Titles option in the top bar to use the overlaying text option as a way of adding captions and subtitles. There are many different font and text styles available under the titles section. Lower Third or Standard are two main styles that can be perfect for subtitles.

4. You can customize the text style in terms of font, size, and colors. Make sure you use a simple font like Arial with a suitable size so that your subtitles are readable on devices of all sizes. Similarly, the font color should be suitable for the background. Generally, white text with a black outline works best for the majority of the videos.

5. While the previous steps are quick and easy to follow, the actual hard part is you have to manually write the text for subtitles and sync it with the video. You will likely have to play back the video multiple times to ensure each subtitle aligns with the audio.
Following are some of the major subtitle editing options in iMovie:
- You can adjust the duration of subtitles by either dragging the edges of the subtitle or clicking on the i button and entering the duration of the subtitle.
- You can either choose to keep the same font style for all subtitles as recommended or bring variety as per your own taste by choosing varying designs for different subtitles.
- Cut or merge the subtitles or even the video to ensure coherency.
Once you have added all the subtitles, recheck the entire video to ensure proper synchronization.
6. After finalizing the video, you can easily save your video by clicking on File and choosing the Share option. Export the video in high-resolution format to ensure maximum quality.

It is evident that the process of adding subtitles in iMovie is a time-consuming process. You have to manually add the captions, which not only takes time but also makes the process vulnerable to a lot of errors. Therefore, it is smart to explore an alternative in which you can automatically transcribe the videos and add subtitles to them.
