What is an SRT File?

SRT (SubRip Subtitle) is the most widely used subtitle format for videos.

SRT Format Example

1
00:00:12,340 --> 00:00:15,670
First line of lyrics
2
00:00:15,670 --> 00:00:18,900
Second line of lyrics

Each subtitle has a number, timestamp range, and text content.

Where SRT Files Are Used

  • YouTube video subtitles
  • Video editors (Premiere, DaVinci, etc.)
  • Social media (TikTok, Instagram via CapCut)
  • Media players (VLC, Plex, etc.)

Manual SRT Creation is Painful

Creating SRT files by hand means typing timestamps in a specific format while constantly pausing and rewinding your audio. Here's why most people switch to automated tools:

❌ Manual SRT Creation

  • Open text editor, type sequence number
  • Play audio, pause at exact millisecond
  • Format timestamp as 00:00:00,000
  • Type the text, find end time, repeat
  • Test in player, fix timing errors, repeat

⏱️ Time per video: 1-3+ hours

✓ With LyricTime

  • Upload your audio file
  • AI transcribes and timestamps automatically
  • Review and fix any errors in visual editor
  • Export properly formatted SRT
  • Import into your editor or platform

⚡ Typical timing pass: ~3-10 minutes (varies by edits)

Understanding SRT Format

SRT is a simple text format that's been the standard for subtitles for decades. Understanding its structure helps you troubleshoot and customize your files.

SRT File Structure

// Sequence number (starts at 1)
1
// Start time --> End time
00:00:12,340 --> 00:00:15,670
// Subtitle text (can be multiple lines)
First line of your subtitles
// Blank line separates entries
2
00:00:15,670 --> 00:00:19,120
Second subtitle entry

Timestamp Format

SRT uses HH:MM:SS,mmm format with comma before milliseconds (unlike VTT which uses a period).

Example: 01:23:45,678 = 1 hour, 23 minutes, 45 seconds, 678 milliseconds

Common Issues

  • • Wrong encoding: Always use UTF-8
  • • Period vs comma: SRT uses comma in timestamps
  • • Missing blank lines: Entries must be separated
  • • Overlapping times: Causes display issues
