Imagine you’re watching a thrilling film on QuickTime, the plot thickens... and then, silence. The characters are talking, but you’re missing every single word. This is a familiar scenario for movie lovers on iOS.

QuickTime is a versatile multimedia player and editor that has been a staple on iPhone, iPad, and Mac devices for years. It offers features ranging from basic video playback to basic video editing options, including screen recording. While QuickTime is an impressive multimedia tool for watching, recording, and even lightly editing videos, adding subtitles isn’t as straightforward.

This article aims to overcome these limitations and provide a clear solution for Mac users who wish to enhance their video viewing experience by adding subtitles to QuickTime. Whether you're a regular user or a video editor, this article will provide a comprehensive guide on how you can use QuickTime player with subtitles.

Part 1: Why Your Subtitles Won't Show in QuickTime Player

You're not alone if you’ve ever encountered issues with subtitles not appearing or syncing correctly in QuickTime Player. This can be frustrating, especially when you're trying to watch a video in a language you're not fluent in or when you need to access closed captions for accessibility purposes.

Several factors can contribute to these problems; and like every other problem, understanding them is the first step to resolving them.

Incompatible Subtitle Format: QuickTime Player primarily supports .qt.text (QuickTime text) subtitle formats. If your subtitles are in different formats like .srt (SubRip Subtitle) and .ttxt (Text Text), they may not display correctly.

Incorrect Encoding: Subtitles are essentially text files, but how they’re encoded matters. QuickTime typically requires subtitles to use UTF-8 encoding for proper display. Files encoded in ANSI, ASCII, or other formats may fail to load entirely.

incorrect file encoding
  • Improper File Naming: Quicktime uses Image names to link subtitles to video files. For the subtitles to work, the subtitle file must have the same name as the video file, albeit with a different extension.

For example; if a video file is named that_movie.mp4, the corresponding subtitle file must be named that_movie.qt.text.

  • Mismatched Timings: Subtitles are synced to specific timestamps within a video. If the timing of your subtitle file doesn’t match the video, the subtitles will either display incorrectly or not at all.
  • Absence of Subtitles in the Video File: Some videos lack embedded subtitles altogether. This leaves you dependent on external subtitle files, which may only sometimes be readily available or compatible.

To address some of these issues, you can either convert your subtitle file to a more compatible format using a subtitle conversion tool or ensure the Image names are matched precisely.

If you’ve addressed all the above and are still facing issues, it may be due to QuickTime’s inherent limitations. In cases like that, external solutions are required.

Part 2: How to Add Subtitles in QuickTime Player on Mac

Adding subtitles to videos in QuickTime Player on your Mac is a straightforward process once you understand the steps involved. For videos that don’t have embedded subtitles, you’ll need to manually attach an external subtitle file to ensure a seamless viewing experience. You can either add your subtitle file directly to QuickTime—which may be a challenge—or use a third-party tool like Subler.

Adding subtitles to QuickTime in this manner allows subtitles to show when you view your video in picture-in-picture (PIP) mode, unlike other media players.

How to Create Custom Subtitles for QuickTime Player

While movies or TV show subtitles are available for download online, videos like social media content, presentations, or personal projects may need you to create subtitles from scratch.

This can seem daunting, but creating custom subtitles ensures your content is accessible, engaging, and easy to follow, especially for viewers who may rely on subtitles for clarity or language support. Thankfully, tools like Wondershare Filmora make this process simple and efficient.
