Frequently Asked Questions
What is Timed Text Markup Language?
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.
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.
How accurate is the AI transcription?
Our AI transcription service provides highly accurate results, with precise timing and synchronization for TTML files. The system is trained on millions of hours of content to ensure professional-quality output.
Can I edit the subtitles after generation?
Yes, you can easily edit the generated TTML files using any compatible subtitle editor. The files are provided in standard format for maximum flexibility.
