Why Use Add Subtitles to Video?
Burned-In Captions That Work on Every Platform and Player
Soft subtitles (SRT/VTT sidecar files) depend on the player supporting external subtitle tracks, and most social media platforms strip them out entirely. Burned-in (hardcoded) subtitles are rendered directly into the video's pixel data, which means they display correctly on every device, every platform, and every player regardless of subtitle support. The text becomes part of the image, as permanent as the video itself.
Accessibility for 466 Million People With Hearing Loss
The World Health Organization estimates that over 466 million people worldwide have disabling hearing loss, and that number is projected to reach 700 million by 2050. Burned-in captions make video content accessible to this audience without relying on platform-specific accessibility features. Beyond hearing loss, captions serve the estimated 85 percent of Facebook video viewers who watch with sound off according to Digiday's reporting, a behavior pattern that extends across Instagram, TikTok, and LinkedIn feeds.
Social Platforms Where External Subtitles Simply Do Not Work
Instagram feed posts, TikTok videos, Twitter uploads, and Facebook native videos do not support external SRT or VTT subtitle files. The only way to display captions on these platforms is to burn them directly into the video. According to Verizon Media and Publicis research, captioned video ads on Facebook had 12 percent longer view times than identical ads without captions, a measurable engagement advantage driven entirely by burned-in text.
Quality Preserved
Video quality remains untouched. Subtitles are added as an overlay without recompressing or degrading your video.

Pro Tips for Subtitles
Check Timing First
Preview your subtitle file with the video before burning. Out-of-sync subtitles can't be fixed after they're burned in.
Keep Text Readable
Use medium or large font size. Keep lines short - 32-42 characters max. Two lines per subtitle is ideal for readability.
Consider Background
White text with black outline works on most backgrounds. If your video has white scenes, test readability first.
Use SRT for Simplicity
SRT is the simplest format. If you just need timed text, SRT works perfectly. Use ASS only if you need advanced styling.
