About TTML
TTML (Timed Text Markup Language) is an XML-based standard for delivering timed text, meaning subtitles and captions, for web video and television broadcast. It's a W3C recommendation and is designed to be a professional, feature-rich format for the broadcast and streaming industry. It supports extensive styling, timing, and layout options and is the basis for many other professional formats like DFXP.
About SRT
SRT (SubRip Text) is the most common and widely supported subtitle format. It's a simple plain text file that contains sequential numbers for each subtitle, start and end timestamps, and the subtitle text itself. Its simplicity and universal compatibility make it the go-to choice for most web videos, streaming platforms, and local media players.

Frequently Asked Questions
Is TTML used by major streaming services?
Yes, TTML and its profiles (like DFXP for Netflix) are the backbone of subtitle delivery for many major streaming platforms, including Netflix, Hulu, and Amazon Prime Video, as well as in professional broadcasting. Its robustness and rich feature set make it ideal for these high-stakes environments.
Is TTML easy to create by hand?
No, TTML is not designed to be human-readable or easily editable by hand. Its XML structure is verbose and complex. It is typically generated and processed by professional authoring software and is not suitable for casual subtitling.
Can I add colors or change fonts in an SRT file?
No, the SRT format does not support any styling. It is a plain text format. If you need styling, you should use a more advanced format like VTT or ASS.
What does 'hearing impaired' mean in SRT files?
Subtitles for the deaf and hard of hearing (SDH) often include descriptions of non-verbal sounds, like '[door slams]' or '[music playing]'. While SRT can contain this text, VTT is often better for more structured accessibility features.
