Generate and correct
Drop the video into suubbs, press Generate, and fix whatever the model misheard — names and jargon, usually. Export SubRip (.srt).
Make the file in suubbs, import it into Final Cut as SRT. Your footage never leaves your Mac, and the two apps meet at a text file four kilobytes long.
Final Cut imports SRT directly, so the two apps meet at a text file about four kilobytes long.
The fastest reliable route is to make the subtitle file where the subtitle tools are, then bring the finished file into the edit. Your footage never moves and Final Cut never has to transcribe anything.
Drop the video into suubbs, press Generate, and fix whatever the model misheard — names and jargon, usually. Export SubRip (.srt).
With your project open in the timeline, choose Import Captions and pick the .srt. Set the caption role and the language subrole in the dialog.
The captions land in a caption lane at the top of the timeline, already positioned by their timestamps. Play it through once and adjust anything that reads long.
Three things, and if none of them apply to you, use Final Cut's own transcription and save yourself a step.
If you want the caption look rather than the caption data — the big styled word-by-word thing — export SubStation Alpha (.ass) from suubbs instead and burn it in with ffmpeg after the export:
ffmpeg -i export.mp4 -vf "subtitles=captions.ass" -c:a copy final.mp4
The parts that trip people up.
CEA-608, iTT and SRT. suubbs exports SRT, which Final Cut imports directly.
Use it if it suits you. The reasons people generate outside Final Cut are word-level timing, a caption style that survives to other platforms, and keeping the footage off a server. If none of those matter, the built-in route is fewer steps.
No. Final Cut applies its own caption formatting, and SRT carries no styling to begin with. Style inside Final Cut, or export ASS from suubbs and burn it in with ffmpeg outside the edit entirely.
Yes — File ▸ Export Captions, which writes SRT or iTT.
No. suubbs transcribes on your own Mac, so the file stays where it is and only a small text file moves between the two apps.
