Best subtitle software for Mac in 2026

The best subtitle software on Mac for filmmakers, compared on transcription, timing, EBU-STL, SCC and IMSC1 support, QC and translation.

The best subtitle software on a Mac depends on which part of the job you need help with. For a fast first transcript, a local transcription app such as MacWhisper or the captioning built into your editor is usually enough. For precise timing and styling, a dedicated editor such as Aegisub gives you more control. For broadcast and streaming deliverables in EBU-STL, SCC or IMSC1, a professional subtitling tool such as Annotation Edit or a platform like OOONA is the safer route. If you want subtitles to stay attached to the cut while it changes, an editor with serious caption tools, including Final Cut Pro, Premiere Pro, DaVinci Resolve or cinemaOS, saves round trips.

This roundup is written for filmmakers and small teams, not subtitling agencies. Features and prices change often, so check each vendor's own site before you commit.

What to compare before you choose

Most subtitle tools look similar in a screenshot. The differences show up in five places.

  • Transcription. Does it run on your Mac or upload audio to a server? Which languages does it handle well, and can it tell speakers apart?
  • Timing. Can you see the audio waveform, snap to shot changes, and enforce a minimum gap between subtitles? Good timing is what makes subtitles feel invisible.
  • Format support. Import matters as much as export. Check that the tool reads what your translator sends back and writes exactly what the delivery spec names, at the right frame rate.
  • QC. Look for checks on reading speed, line length, line count, overlaps and gaps. Broadcasters and streaming services publish their own style guides, and the numbers differ, so a tool that lets you set the limits is worth more than one with fixed rules.
  • Translation. Machine translation can give a translator a head start, but every language still needs a human review before delivery. Note whether translation happens locally or in the cloud, especially for unreleased films.

If you are unsure what each format is for, our guide to subtitle formats from SRT to IMSC1 explains who asks for what.

Subtitles inside your editor

Working in the editor keeps captions next to the picture, which matters when the cut is still moving.

Final Cut Pro

Final Cut Pro has captions built into the timeline as roles, and recent versions add Transcribe to Captions, which runs on the Mac rather than in the cloud and needs a recent macOS on Apple silicon. It works with iTT, SRT and CEA-608 captions, which covers Apple platforms, most web players and US-style closed captions. It is a good fit if you already cut in Final Cut and deliver to the web or Apple. For European broadcast formats, you will likely need another tool. Check Apple's documentation for the languages transcription currently supports.

Premiere Pro

Premiere Pro has Speech to Text for transcription and a captions workflow that covers several broadcast standards, and recent versions add caption translation. It is a solid choice if you already work in Creative Cloud and hand projects to teams who expect Premiere. The format list is broad, but it varies by caption type, so check Adobe's current documentation against your spec before you rely on it for a broadcast delivery.

DaVinci Resolve

Resolve handles subtitle tracks on the timeline in the free version: you can import an SRT file, edit and style the subtitles, and export common formats such as SRT and WebVTT, or burn them into the picture. Automatic subtitle creation from audio has been a DaVinci Resolve Studio feature rather than part of the free version, so check Blackmagic Design's current feature list. It suits editors who already finish in Resolve. The subtitle tools are practical rather than specialist, so dedicated QC is limited compared with professional subtitling software.

cinemaOS

cinemaOS, from Momentum Studios, puts subtitles in the Finisher room under Localize. It transcribes on your Mac, so no dialogue is uploaded, then lets you correct the text, translate locally, compare both languages side by side, run delivery checks and export. Supported formats for import and export are SRT, WebVTT, ASS, SCC (CEA-608), EBU-STL, Apple iTT and FCPXML captions, plus burned-in subtitles. Transcribe and edit by text in the Sequencer uses the same local transcription, so the subtitles and the cut come from one source. The offline subtitles tutorial shows the whole path in under a minute.

The limits, stated plainly: IMSC1 is not on its tested format list today, so if your spec asks for IMSC1, use a dedicated tool for that file. Platform conformance still needs the recipient's current spec and a human language review. cinemaOS is Mac-only on Apple silicon (version 0.2, Build 9), with Windows planned for November 2027. It costs $9.99 USD per month excluding VAT, with 60 days free, no card and no automatic charge.

Local transcription apps

If you only need a transcript and a first subtitle file, a standalone app may be all you need.

MacWhisper runs OpenAI's Whisper speech models on your Mac and exports subtitle files such as SRT and WebVTT. It is quick to learn and keeps audio local, and it comes in a free version and a paid Pro version, so check which features sit in which tier. It is not a timing or QC tool, so expect to tidy line breaks and durations elsewhere.

Descript is built around editing video by editing its transcript, and it can export captions. It works through an online account, which suits many creators but deserves thought for confidential material. Our comparison of Descript alternatives with local transcription covers the trade-offs.

Dedicated subtitle editors

Free, open-source editors give you finer control over timing and styling than most video editors.

  • Aegisub is the long-standing choice for styled subtitles in ASS. It shows the audio waveform or spectrum for precise timing and can snap to video keyframes. Development of the original project has slowed, and community-maintained forks carry it forward, so check which build supports your macOS version.
  • Subtitle Edit is a widely used free editor with a long list of formats, waveform timing, error checks and optional Whisper transcription. It has been a Windows-first app, and Mac use has historically relied on workarounds, so check the project's site for current Mac support.

Both are excellent for fixing a file someone else made. Neither is designed around film delivery specs from broadcasters.

Professional subtitling tools

When a broadcaster or streaming service hands you a detailed timed-text spec, professional tools earn their cost.

  • Annotation Edit is a paid, Mac-native subtitling application aimed at professional deliverables, with format conversion and checks for broadcast and streaming work.
  • OOONA is a paid, browser-based subtitling platform widely used by language service providers. Because it runs in the browser it works on a Mac without a native app. For unreleased work, ask the vendor how media and subtitle text are stored and processed.

These tools focus on conformance: frame-accurate timing against shot changes, style-guide rules per client, and export profiles for formats such as EBU-STL, SCC and the TTML family, including IMSC1. Check each vendor's current format list and pricing, since both change. If you only deliver to festivals and the web, they may be more than you need.

Matching the tool to the delivery

A practical way to decide is to start from the file you must deliver.

  • SRT or WebVTT for festivals and the web. Any tool above will do. Pick the one closest to where you edit.
  • SCC for US broadcast. Final Cut Pro, Premiere Pro, cinemaOS and the professional tools can write it. Plan for short lines, because the CEA-608 caption grid is tight.
  • EBU-STL for European broadcast. cinemaOS and the professional tools can produce it, and Premiere Pro offers it as a caption export for its EBU subtitle type, so confirm the option in your version. Because it is binary, validate the file rather than opening it in a text editor.
  • IMSC1 for streaming platforms. Use a professional subtitling tool, or confirm that your editor's current version exports the exact profile the platform asks for.
  • Several languages on a tight budget. Local transcription and translation give translators a draft to correct. Our guide to translating subtitles locally on a Mac walks through a review pass.

A sensible workflow for a small team

  1. Lock the cut, or at least the reel, before final subtitle timing.
  2. Transcribe locally and correct names, terms and speakers first.
  3. Set line length and reading speed limits from the delivery spec, not from memory.
  4. Time against shot changes and the waveform, then run QC.
  5. Translate, then have a fluent speaker review every language.
  6. Export exactly the format, frame rate and character encoding the spec names, and play each file back on the picture before sending.

FAQ

Is there free subtitle software for Mac?

Yes. Aegisub is free and open source, DaVinci Resolve's free version edits and exports subtitle tracks, and several local transcription apps have free tiers. Free tools are fine for SRT and WebVTT. Broadcast formats usually need more careful QC.

Can I make EBU-STL or SCC files on a Mac?

Yes. Professional tools such as Annotation Edit handle them, and some editors export them too, including cinemaOS for both, Premiere Pro depending on caption type, and Final Cut Pro for SCC through its CEA-608 captions. Always check the recipient's spec for frame rate and character set.

Does machine translation replace a subtitle translator?

No. It gives a useful draft, especially for timing and structure, but meaning, tone, names and line breaks need a fluent human. Budget for review in every language.
