SRT vs TTML Format Comparison

SubRip Subtitle (.srt)

  • The most widely supported subtitle format
  • Uses numbered cues with start and end timestamps
  • Compatible with video editors and media players
  • Simple plain-text structure for distribution
1
00:00:12,500 --> 00:00:16,800
First line of lyrics
2
00:00:16,800 --> 00:00:20,500
Second line of lyrics

Timed Text Markup Language (.ttml)

  • XML-based timed text format
  • Used in broadcast and streaming delivery pipelines
  • Stores cues with begin and end attributes
  • Good for structured subtitle interchange
<?xml version="1.0" encoding="UTF-8"?>
<tt xmlns="http://www.w3.org/ns/ttml">
<body><div>
<p begin="00:00:12.500" end="00:00:16.800">First line of lyrics</p>
</div></body>
</tt>
