MCC captions and CSV spreadsheet, explained

The .mcc format outlived its creator. MacCaption is retired, CaptionMaker is Windows-only and paid, and nothing else opens the format. That's a problem when a vendor returns a deliverable and someone asks what's in it. This converter decodes the CEA-708 caption data into a review spreadsheet with one row per caption, exact timing and readable text. When you need an editable subtitle file instead of a report, use the MCC to SRT converter.

CEA-708 .mcc captions decoded into a spreadsheet, no MacCaption required. It is free to start, encrypted in transit, and converts a whole batch into one ZIP — sign in when you need large, high-volume jobs.

MCC to CSV FAQ

Why convert MCC to CSV?

To read and QC a broadcast deliverable without captioning software. MacCaption is retired, and nothing mainstream opens .mcc files.

Is the decoding verified?

Yes. We validate the CEA-708 decoding against the same reference caption data our other broadcast converters use, with round-trip testing.

Does positioning or styling carry into the CSV?

No. The CSV carries timing and text, which is what review and QC need. Position codes have no spreadsheet equivalent.

Can I get an SRT instead?

Yes. The MCC to SRT converter writes an editable subtitle file from the same decoder.
