Burn In Subtitles open in OneMacApp, with its settings in the inspector.

How it works

Three steps.Nothing to learn.

  1. 1

    Drop your videos

    Add a clip with speech in it. With one video open you can generate the captions and watch them over the picture first.

  2. 2

    Choose the captions

    Pick Transcribe and a language, or From File and choose an SRT. Then pick Small, Medium or Large text.

  3. 3

    Press Burn In

    The captioned MP4 is saved in a dated OneMacApp folder in Downloads. Your original stays clean.

The details

Everything you’d want.Nothing you wouldn’t.

  • Transcribed on your Mac

    Speech is turned into captions with Apple’s on-device transcription. The language is downloaded once, then it works offline.

  • Or bring your own SRT

    Already have subtitles, or translated some with Translate? Choose the SRT file and it is drawn in as it is.

  • Shows everywhere

    Burned-in captions are part of the picture, so they appear on social feeds, in chat apps and on players that ignore subtitle files.

  • Clean, readable style

    White text with a soft outline near the bottom of the frame, in three sizes.

FAQ

Questions,answered.

Drop the video into Burn In Subtitles, leave it on Transcribe, pick the spoken language and press Burn In. The captions are written and drawn into a new MP4.

No. It uses Apple’s speech recognition on your Mac. The first time you use a language it is downloaded from Apple, and after that it works offline.

Save the captions as an SRT with Transcribe, correct them in any text editor, then use From File here to burn in your edited version.

Normal subtitles live in a separate file that the player can switch on or off. Burned-in subtitles are part of the picture, so they always show and cannot be turned off.

SRT files. If yours is in another format, most subtitle editors can save it as SRT.
