DFXP subtitle generator
Generate subtitles in DFXP format for your video
What is the DFXP format?
Here are some key points about the DFXP format:
- File extension: The Distribution Format Exchange Profile files use the extension .dfxp (sometimes .xml or .ttml depending on the implementations).
- Structure: The DFXP is a hierarchical XML file comprising tags that define textual content, timing, and formatting. Its structure generally consists of three sections:
- <head>: contains the metadata and styles (font, color, alignment, etc.).
- <layout>: defines the position on the screen (top, bottom, centerโฆ).
- <body>: contains text blocks synchronized with timecodes.
- Specificity: The DFXP format offers great flexibility for formatting and positioning. It supports CSS-like styles and rich XML tags, allowing for consistent presentation across different devices. It can include advanced metadata such as languages, audio descriptions, or scene identifiers.
- Compatibility: The DFXP is recognized by many streaming platforms and professional tools, including Netflix, Adobe Premiere, Final Cut Pro, or AWS MediaConvert. It is used in digital broadcast streams and OTT (Over-The-Top) platforms to ensure interoperability between systems and consistent rendering quality across different media (TV, web, mobile).

Frequently Asked Questions
What is the difference between DFXP and TTML?
TTML (Timed Text Markup Language) is the comprehensive base standard for subtitles, offering a wide range of styling and positioning features.
The DFXP (Distribution Format Exchange Profile) is not a distinct format, but a specific profile of TTML (specifically TTML 1.0) designed to simplify the exchange and distribution of subtitles using a subset of these features.
In practice, the terms are often used interchangeably, but DFXP refers to a more constrained and historical implementation of the TTML standard.
