The actual steps

No exporting audio manually, no juggling files between apps — the whole path stays inside Premiere Pro.

1️⃣

Select clip or sequence

Pick a single clip, or run Whisper across a full sequence in one pass, respecting gaps between clips.

2️⃣

Whisper transcribes locally

Audio is extracted and fed to the Whisper model running on your machine — word-level timestamps come back.

3️⃣

SRT lands on your timeline

The result imports as a standard, editable Premiere Pro caption track.

What makes Whisper-based subtitles different

Whisper's training on a huge, varied multilingual dataset tends to make it noticeably better than older speech-recognition engines at handling accents, background noise, and non-English languages — which is the main reason CaptionLab is built on it rather than a narrower, English-first engine.

Frequently asked questions

How long does generating subtitles for a 10-minute clip take?
It depends on your hardware — typically a few minutes on Apple Silicon or an NVIDIA GPU, longer on CPU-only systems.
Can I edit the subtitles after they're generated?
Yes — they land as a normal, editable Premiere Pro caption track, just like manually-typed captions.
Does it work across multiple clips at once?
Yes, CaptionLab can process a full sequence in one pass, correctly handling gaps and boundaries between clips.
