Subtitle Hardcoding

Burn professional subtitles directly into your videos with full control over fonts, colours, positioning, and styling.

What Are Open Captions?

Open captions (hardcoded subtitles) are permanently burnt into the video itself and cannot be turned off by the viewer. Unlike closed captions which rely on a separate subtitle file, hardcoded subtitles are always visible, making them ideal for platforms that don't support external subtitle files or when you need guaranteed visibility across all devices.

Why Choose Our Hardcoding Service?

Full Customisation

Choose from 15 fonts, set custom colours for text and outlines, adjust sizing, and position subtitles exactly where you want them on screen.

Fast Processing

Our cloud-based processing handles the heavy lifting. Upload your video and subtitle file, customise the styling, and get your hardcoded video back quickly.

High-Quality Output

Videos are processed at their original quality. Subtitles are rendered cleanly with anti-aliasing, outlines, and shadows for maximum readability.

Secure Processing

Your videos are processed securely and deleted after completion. Enterprise-grade security ensures your content remains confidential.

How It Works

1. Upload Your Files

Upload your video file along with a subtitle file (SRT, VTT, ASS, or SSA format). You can use subtitles generated by our AI transcription, or upload your own existing subtitle file.

2. Customise Your Style

Choose your font, set colours for text and outlines, adjust the font size, enable bold or italic styling, and position the subtitles on screen. Preview your choices before processing.

  • 15 fonts including Arial, Roboto, Montserrat, Poppins, and more
  • Custom colours for text, outlines, and shadows
  • Adjustable sizing and bold/italic options
  • Vertical positioning to place subtitles where you need them

3. Download Your Video

Once processing is complete, download your video with the subtitles permanently burnt in. The output maintains the original video quality with cleanly rendered subtitles.

Perfect For

Social Media

Instagram Reels, TikTok, and YouTube Shorts don't always support external subtitle files. Hardcoded subtitles guarantee your captions are always visible to every viewer.

Corporate Videos

Internal training videos, presentations, and company communications benefit from always-visible subtitles that work across all devices and video players without configuration.

Broadcast & Events

Conference recordings, webinars, and broadcast content where you need subtitles visible regardless of the playback environment or device capabilities.

Accessibility

Ensure your content is accessible to deaf and hard-of-hearing audiences without relying on viewer settings or platform support for closed captions.
