How to generate a transcript from a video on Mac

On-device vs cloud transcription

Most transcription tools send your audio to a remote server. Lossless Video Cutter uses Apple's on-device speech recognition - the same engine as macOS Dictation when it runs in offline mode. Your audio never leaves your machine.

This matters for interview footage, confidential meetings, medical discussions, legal depositions, or any content where privacy is a concern. It also means the tool works anywhere - on a plane, in a location with no Wi-Fi, or in a network-restricted environment.

Step-by-step

1. Open your video with ⌘O.
2. Open the Transcribe sheet via Edit → Transcribe.
3. Select the language. The app detects the system's available languages. Choose the language spoken in the video if the default isn't correct.
4. Click Transcribe. The app processes the audio on-device. For a one-hour video this typically takes a few minutes depending on your Mac's chip.
5. Review the result. The transcript appears as a list of timed lines, each corresponding to a natural speech segment.

What you get

The transcript is a timed document. Every line has a timestamp, and clicking any line moves the playhead to that exact moment in the video. Lines correspond to natural speech segments - not arbitrary fixed intervals - so the structure follows the rhythm of the speaker.

This makes the transcript itself a navigation tool. Scan it visually to find the section you want, click the line, and you're there instantly without scrubbing.

Using the transcript to find content

Once the transcript is generated, click any line to jump to that moment. From there you can:

• Add the moment as a segment with I and O to mark in and out points around the spoken content
• Pull specific answers from a long interview by reading the transcript and clicking each relevant line
• Identify key moments in a talk or lecture and build a highlights segment list directly from the transcript view

Exporting the transcript

The transcript text can be copied from the sheet for use elsewhere - in a document, a note, a caption editor, or any other tool. This is useful when you need a rough transcript for show notes, a blog post, or a review document, without reaching for a separate transcription service.

Supported languages

The app supports all languages available through macOS Dictation on your system. The available set depends on your macOS version and which language packs you have downloaded. You can add additional languages in System Settings → Keyboard → Dictation.
