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 SBV
SBV (SubViewer) is a very simple, comma-separated subtitle format. It's most known for being one of the formats used by YouTube for caption uploads. The format consists of a start and end time on a single line, followed by the subtitle text. It's a very basic format without any styling capabilities, similar in simplicity to SRT.

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.
Is SBV the same as SubViewer (.sub)?
They are very similar but have distinct formatting. The .sbv extension is specifically associated with YouTube's variant of the format. While they share the same core principle of 'start_time,end_time' followed by text, there can be minor incompatibilities between them. Our converter handles both.
Why would I use SBV?
The primary reason to use SBV is for uploading captions to YouTube, as it's one of their natively supported formats. It's a simple, no-frills format that is easy to create and edit in a plain text editor.
