Hard Sub vs Soft Sub: Pros and Cons of Each Subtitling Technique


Subtitles play a crucial role in enhancing the accessibility and understanding of audiovisual content for a global audience. Two common subtitling techniques used in the industry are hard subbing and soft subbing. Both methods offer their own advantages and disadvantages, catering to different needs and preferences. Let us explore the pros and cons of each.

Hard Subtitles

Hard subtitles, also known as burnt-in subtitles, are permanently embedded in the video frames. They cannot be easily turned on or off, making them suitable for situations where subtitles should always be present or when distributing content with fixed translations. Here are the pros and cons of hard subtitles:


  • Compatibility: Hard subtitles are universally supported by any device or media player, as the subtitles are fused directly into the video.
  • Guaranteed Display: Viewers cannot accidentally disable or overlook the subtitles, ensuring that everyone understands the dialogue and content.


  • Limited Customization: Hard subtitles lack flexibility for individual customization. Font styles, sizes, and colors are predetermined and cannot be adjusted by the viewer.
  • Language Selection: As all translations are embedded, videos with hard subtitles may need multiple versions for different languages, resulting in larger file sizes.

Soft Subtitles

Soft subtitles are separate files connected to the video and can be turned on or off according to the viewers’ preferences. They provide more flexibility, enabling customization and multiple language options. Here are the pros and cons of soft subtitles:


  • Flexibility: Soft subtitles allow viewers to choose whether to display the subtitles or not, providing customization options based on individual needs and preferences.
  • Multiple Languages: One video file can have various subtitle files, making it easier to distribute content globally without increasing file size significantly.


  • Dependent on Media Player: Soft subtitles require media players that support external subtitle files, which may not be available on older or less advanced devices.
  • Compatibility Issues: Different subtitle file formats (e.g., .srt, .ass, .ssa) can cause compatibility issues when playing on various platforms. Subtitle syncing problems may also occur.


Both hard and soft subtitling techniques offer their own set of advantages and disadvantages. Hard subtitles guarantee display and compatibility, but lack customization options and can result in larger video files. On the other hand, soft subtitles provide flexibility, multiple language options, and smaller file sizes, but require compatible media players and may encounter syncing and format compatibility issues. The choice between hard and soft subtitles depends on the specific requirements of the content and its distribution.


1. How do I enable or disable soft subtitles?

To enable or disable soft subtitles, you need to use a media player that supports external subtitle files. Most media players provide options to turn on or off subtitles in their settings menu or through shortcut keys.

2. Can I change the appearance of soft subtitles?

Yes, most media players allow customization of soft subtitles. You can usually change the font, size, color, and position of the subtitles based on your preferences.

3. Which subtitling technique is more suitable for online streaming platforms?

Soft subtitles are commonly used on online streaming platforms as they offer greater flexibility for viewers to choose their preferred language and customize the appearance of the subtitles.
