About TXT
A plain text (.txt) file is the simplest possible format, containing only raw text characters without any timing or styling information. When used in the context of subtitles, it typically represents a transcript of the audio. To be used as subtitles, this transcript would need to be processed by another tool to add the necessary timestamps to sync the text with the video.
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.

Frequently Asked Questions
How can I turn a TXT transcript into an SRT file?
This process is called 'timing' or 'syncing'. It requires specialized software where you can load the video and the text file, and then go through the video, marking the start and end times for each line of dialogue. Many professional subtitle editors offer features to help with this process.
When is a plain TXT file useful?
A plain text file is very useful for creating a simple, readable transcript of a video for reference, for search engine optimization (SEO), or as the first step in a translation workflow before the text is timed.
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.
