FAQs About Subtitle Editing on Mac
1. Can I add subtitles to video in iMovie?
Yes. As the built-in video editor for Mac, iMovie allows you to manually add subtitles to your videos. To do this, you’ll need to select a title template and carefully listen to the narration in order to type out each phrase accurately. While iMovie is a free and convenient option for Mac users, it does come with some limitations: the process can be time-consuming, and you cannot remove or modify the animation effects embedded in the preset title styles.
If you’re looking for a more efficient solution, consider using FlexClip’s auto subtitle generator. This tool can automatically extract subtitles from your video and offers greater flexibility in customizing the subtitle layout, saving you time and effort.

3. Can VLC edit subtitle files?
No, VLC is primarily a media player and does not include subtitle editing features. While it can play videos with subtitles, it cannot generate or edit subtitle files.
