To add subtitles to a video on a Mac, transcribe the video's audio into a timestamped caption file (SRT or VTT), then load that file into your video editor or upload it alongside the video. TranscribeAnything does the hard part on-device: drop the MP4 or MOV in, and it produces synced SRT and VTT you can drop straight into Final Cut, Premiere, CapCut, YouTube, or a web player — in a few minutes, with no upload.
| Format | Best for |
|---|---|
| SRT | Final Cut, Premiere, DaVinci, CapCut, YouTube uploads — the universal subtitle file |
| VTT | Web video (HTML5 <track>), some streaming players and CMSs |
Both carry the same timestamped lines; pick the one your destination expects. When in doubt, SRT is accepted almost everywhere. TranscribeAnything runs Apple's on-device speech engine at up to 80× realtime, supports 10 languages, and costs $19.99/year for unlimited transcription — the first 5 transcriptions (up to 30 minutes each) are free.
The majority of social video is watched on mute, so captions aren't an accessibility afterthought — they're what makes the video land at all. They also make video content searchable and quotable, and they meet accessibility requirements for public-facing and educational material. Generating them on-device means you can caption confidential or unreleased footage without uploading it anywhere.
