SRT (SubRip Text) is the most widely used subtitle file format. An SRT file contains numbered subtitle entries, each with a timestamp range and text. It's supported by virtually every video player, editing software, and platform (YouTube, Vimeo, Facebook, etc.). GeekLink can auto-generate SRT files from video using AI, or you can import and edit existing SRT files.
The SRT format was created by the SubRip software project for extracting subtitles from DVDs. Its simplicity — just plain text with timestamps — made it the de facto standard. Today, SRT is supported by YouTube, Vimeo, Facebook, LinkedIn, Twitter/X, Netflix (for submissions), and every major video player (VLC, MPV, QuickTime). While more advanced formats exist (ASS for styled anime subtitles, WebVTT for web), SRT remains the safest choice for compatibility. If you need to distribute subtitles across multiple platforms, SRT is the format to use.
SRT format: each entry has 3 lines — 1) Sequential number (1, 2, 3...), 2) Timestamp range (00:01:23,456 --> 00:01:25,789), 3) Subtitle text (can be multi-line). Entries are separated by blank lines. Timestamps use comma (,) as millisecond separator, not period. Encoding should be UTF-8 for international characters.
An SRT (SubRip Text) file is a plain-text subtitle file containing numbered entries with timestamps and subtitle text. It's the most widely supported subtitle format across video players and platforms.
Use GeekLink to auto-generate SRT from video: import your video → use Whisper speech-to-text or OCR → export as SRT. You can also create SRT manually in a text editor, but AI generation is much faster.
SRT and VTT (WebVTT) are very similar. VTT supports styling (bold, italic, colors) and positioning, while SRT is plain text only. YouTube accepts both. SRT has wider compatibility across non-web platforms.
Yes! Go to YouTube Studio → select your video → Subtitles → Add language → Upload file → select your SRT. YouTube will display the subtitles as a selectable language track for viewers.
