Frequently Asked Questions
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.
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.
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.
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.
Yes. Files are transferred over HTTPS and automatically deleted from the server after the DFXP is ready for download.
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.
LRC files are plain text and very compact. The 50 MB server limit is not a concern for any LRC file.
