About CSV
CSV (Comma-Separated Values) is a simple text format for storing tabular data. In the context of subtitles, it's often used for translation workflows or bulk editing. Each row in the CSV file can represent a subtitle cue, with columns for the start time, end time, and text. It's easy to open and edit in any spreadsheet program like Excel or Google Sheets.
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
Can I use a CSV file directly as a subtitle?
No, a CSV file cannot be used directly as a subtitle track in a video player. It's an intermediate format. You would need to convert the CSV file into a standard subtitle format like SRT or VTT after you have finished your edits or translations.
What is the best use case for CSV subtitles?
CSV is ideal for workflows where non-technical users need to edit or translate subtitle text. Giving a translator a simple spreadsheet is much easier than asking them to edit the strict syntax of an SRT or VTT file. It's also great for programmatically managing subtitle data.
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.
