Frequently Asked Questions

What is DFXP format used for?

DFXP (Distribution Format Exchange Profile) is an XML-based subtitle format used in broadcast and professional video workflows. It is widely supported by professional subtitle delivery and editing tools.

Does LRC have end times that map to DFXP?

LRC only has start timestamps. The converter estimates end times as the start of the next cue minus a small gap, or adds a 3-second duration for the final cue.

Will LRC metadata tags appear in the DFXP output?

LRC metadata tags (ti:, ar:, al:, by:) are added as metadata elements in the DFXP head section where possible. They do not become subtitle cues.

Can I add DFXP styling after conversion?

Yes. The DFXP output is well-formed XML that you can edit to add tts:fontStyle, tts:color, tts:textAlign, and region attributes required for your delivery specification.

Are my files deleted after conversion?

Yes. Files are transferred over HTTPS and automatically deleted from the server after the DFXP is ready for download.

What timestamp format does DFXP use?

DFXP uses HH:MM:SS.mmm format for begin and end attributes. LRC's [MM:SS.xx] centisecond timestamps are converted to this format during processing.

Is there a file size limit?

LRC files are plain text and very compact. The 50 MB server limit is not a concern for any LRC file.

Can I convert DFXP back to LRC?

Yes. ChangeThisFile supports DFXP to LRC conversion for round-tripping between formats.

Does the converter handle enhanced LRC?

Enhanced LRC has word-level timestamps in angle brackets. The converter uses line-level timestamps and includes the full line text, stripping word-level timing markers.

Is the DFXP output valid XML?

Yes. The output is well-formed XML with standard TTML namespace declarations that can be validated with any XML parser.
