MacCaption alternatives: what to use now that it's retired

MacCaption is gone: Telestream published its retirement notice in March 2022, sold the last new license on April 30, 2022, and ended support — including new versions and macOS compatibility updates — on May 1, 2023. Its Windows sibling CaptionMaker continues, which means Telestream's official answer for Mac captioning shops is, effectively, "switch to Windows." If that's not your answer, the right alternative depends on which part of MacCaption you actually used: full caption authoring, or the format conversion between SRT, SCC, MCC, and STL that many editors bought it for. This guide covers both, honestly.

What happened to MacCaption

MacCaption was, for years, the standard Mac tool for broadcast closed captioning — authoring CEA-608/708 captions, exporting .scc and .mcc, and encoding captions into video. Telestream's retirement schedule:

• March 2022 — retirement announced
• April 30, 2022 — final date to purchase new licenses
• May 1, 2023 — end of support: no more updates, no new versions, no macOS compatibility fixes

Existing installs keep running, but each macOS release is a gamble with no fix coming. CaptionMaker (Windows) remains for sale, and Telestream's enterprise captioning now lives in Vantage.

First, decide what you're replacing

MacCaption bundled two jobs that its alternatives split apart:

1. Caption authoring — writing and timing captions against video, positioning text, checking Safe Title, encoding into media. You need a captioning application for this.
2. Format conversion — turning an SRT (or a transcript) into a broadcast .scc, .mcc, or .stl deliverable, or decoding one of those back to an editable format. You need a converter for this, and many MacCaption seats existed mostly for this job.

Alternatives for caption authoring

• CaptionMaker (Telestream, Windows) — the closest functional match, since it shares MacCaption's lineage and formats. The catch is the platform: it's Windows-only, so for a Mac shop it means a VM, a Windows machine, or a platform switch. Perpetual and subscription licensing; pricing on request.
• EZTitles (Windows) — the high-end professional subtitling/captioning suite widely used in broadcast and localization. Deep format support (SCC, MCC, STL, TTML/IMSC) and QC tooling. Also Windows-only, priced accordingly for professional facilities.
• Closed Caption Creator (macOS/Windows/web) — a modern, subscription-priced captioning app that positions itself explicitly as a MacCaption replacement, with 608/708 authoring and SCC/MCC export on the Mac.
• Subtitle Edit (free, open source) — the free workhorse. Windows-native (usable on a Mac via a VM, and a partial online version exists). Reads and writes a long list of formats including SCC, though broadcast users routinely double-check its 608 output against a reference decoder. No 708/MCC authoring.

Alternatives for format conversion

If what you actually did in MacCaption was "open the SRT, export the SCC" — the deliverable-conversion job — you don't need an authoring suite at all. CutConvert's converters run in any browser on any Mac (or anything else), with no install:

• SRT to SCC and SCC to SRT — CEA-608 with drop-frame timing, pop-on captions, and the format's positioning and character-set rules handled
• SRT to MCC and MCC to SRT — CEA-708 MacCaption-format .mcc files (including the standard Telestream permission notice the format requires)
• SRT to STL and STL to SRT — EBU-STL (Tech 3264) for European broadcast delivery

The output is verified against reference decoders — the same caption files Comcast's open-source caption-inspector project uses as test media round-trip through these converters accurately. Broadcast conversion is free to try on small files; paid plans start at $9/month. To be clear about the limits: CutConvert converts and validates files — it is not an authoring tool, has no video preview, and won't burn captions into media. For that, you want one of the applications above.

Quick comparison

The honest summary: for authoring on a Mac without Windows, Closed Caption Creator is the closest like-for-like replacement; for maximum capability and a facility budget, EZTitles or CaptionMaker (on Windows); for zero budget and format breadth, Subtitle Edit; and for the pure SRT↔SCC/MCC/STL conversion step, a browser converter replaces that slice of MacCaption outright.

FAQ

Is MacCaption still supported? No — Telestream ended MacCaption support on May 1, 2023, after closing new-license sales on April 30, 2022. Installed copies keep working, but there are no further updates or macOS compatibility fixes. CaptionMaker, the Windows product, remains available.

What is the best MacCaption alternative on a Mac? For full caption authoring on macOS, Closed Caption Creator is the most direct replacement. If you only used MacCaption to convert between SRT and broadcast formats (SCC, MCC, STL), a browser-based converter covers that job on any platform without an install.

Can I still convert SRT to SCC without MacCaption? Yes — the SRT to SCC converter writes CEA-608 .scc files with drop-frame timing and pop-on caption encoding, in the browser. The reverse direction (SCC to SRT) works the same way.

What about .mcc files — does anything else write them? Yes. The .mcc format (CEA-708 caption data in MacCaption's container) is documented and openly licensed by Telestream with a required attribution notice, and other tools — including the SRT to MCC converter here — write compliant files that carry that notice.

Is Subtitle Edit good enough for broadcast SCC delivery? Often, with checking. Subtitle Edit is free and writes SCC, but it's a general-purpose subtitle tool rather than a broadcast captioning suite — facilities typically verify its 608 output against a reference decoder before delivery, and it doesn't author 708/MCC.

Do I need Windows to run CaptionMaker or EZTitles? Yes — both are Windows applications. Mac shops run them in a virtual machine or on a dedicated Windows workstation; that overhead is exactly why Mac-native and browser-based alternatives are worth considering first.
