About DFXP
DFXP (Distribution Format Exchange Profile) is a profile of the more general TTML standard. It was created to standardize subtitle delivery for streaming services and is famously used by platforms like Netflix. It is an XML-based format that contains rich information about timing, styling, and positioning, ensuring high-quality, professional, and accessible captions for digital distribution.
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 DFXP the same as TTML?
DFXP is a specific implementation, or 'profile', of TTML. Think of TTML as a large toolbox with many options, and DFXP as a specific set of those tools chosen for a particular job (web streaming). While a DFXP file is a TTML file, not all TTML files are valid DFXP files.
Do I need to worry about DFXP as a casual user?
No, DFXP is a professional delivery format. As a user, you will almost never encounter DFXP files directly. They are processed and delivered by the back-end systems of streaming platforms. If you are creating subtitles, you will typically work with SRT or VTT.
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.
