Watching videos with subtitles can be a game-changer, especially if you’re learning a new language, trying to understand a foreign accent, or simply prefer watching with captions. While many video players offer temporary subtitles, permanently embedding subtitles directly into your MP4 video ensures that they’re always available, regardless of the platform or device used for playback. This article will guide you through the process of adding subtitles to MP4 videos, covering various methods and tools to help you achieve the desired result.
Understanding the Basics of Subtitles
Before diving into the technical details, let’s clarify what we mean by “permanently adding subtitles to MP4.” Essentially, we’re talking about creating a new MP4 file that includes the subtitles as part of the video stream, rather than as a separate file. This ensures that the subtitles are always displayed along with the video, regardless of where it’s played.
Types of Subtitles
There are two main types of subtitles:
- Closed Captions: These subtitles are intended for the hearing impaired and provide a textual representation of the audio, including sound effects and background noises.
- Open Captions: These subtitles are designed to be visible for all viewers, even those with normal hearing. They often include additional information like speaker names or translations.
Subtitle File Formats
The most common subtitle file formats include:
- SRT (SubRip): A simple text-based format that’s widely supported across different platforms and devices.
- ASS (Advanced SubStation Alpha): A more advanced format that supports styling options like fonts, colors, and animation.
- SSA (SubStation Alpha): A similar format to ASS, but without the animation capabilities.
Tools and Methods
Now that we understand the basics, let’s explore the different methods and tools available to permanently add subtitles to your MP4 video:
