Subtitles Pro transcribes your sequence and gives you a real editor on top of it: fix a word, move a line break, split or merge captions, run a find & replace, translate into another language, then export an SRT. It is the text half of PremiereGPT’s caption tooling. If you want styled, burned-in captions on your timeline, use Smart Captions — it shares this exact editor and adds a design step. Works in Premiere Pro and DaVinci Resolve.

​
Quick Start

1

Open the tool

Open Subtitles Pro from the Tools Menu, with your sequence open.
2

Set the language and the caption limits

Pick the spoken Language (or leave it on Auto), then set Max Chars and Max Gap to shape how captions are cut.
3

Transcribe

Click Transcribe. The chevron on its left lets you pick a different engine first.
4

Edit

Fix anything that’s wrong directly in the transcript — words, breaks, punctuation, casing.
5

Generate SRT

Click Generate SRT. The file lands in your export folder.
Subtitles Pro handles sequences up to 2 hours. Longer ones are refused before any work starts.

​
General

Naming the language explicitly beats Auto whenever you know it — especially on accented speech, technical vocabulary, or audio that starts with music or silence.
Max Chars by format:
  • 15–25 — one short line at a time, social / vertical style.
  • 30–45 — the classic subtitle range. Comfortable to read, matches broadcast habits.
  • 50+ — long lines for wide screens and dense dialogue.
Max Gap shapes rhythm: a low value cuts a new caption at every small pause (choppy but precise), a high value keeps sentences together across breaths (smoother, longer captions).

​
Correction

The correction pass fixes spelling, punctuation and obvious transcription slips. Turn it off only if you want the raw output untouched — for example when you’ll be conforming to an existing script by hand.

AI Context

A free-text box (up to 800 characters) read by the transcription itself. This is where you protect the words a generic model will get wrong. What to put in it:
  • Proper nouns: “The company is called Kwerty, the CEO is Anaïs Rouvier.”
  • Product and brand names: “Our products: FlowKit, FlowKit Pro, DeskSync.”
  • Jargon and acronyms: “We say ARR, MRR, ICP, and ‘go-to-market’ spelled with hyphens.”
  • Preferred spelling: “Write ‘e-mail’, not ‘email’.”
  • Language mixing: “French speech with English tech terms — keep the English terms in English.”
What not to put in it: styling, caption length, translation requests or editing instructions — none of that is read here. Length is Max Chars; style lives in Smart Captions.
A list of ten proper nouns in this box removes more errors than any engine upgrade. It is the cheapest quality win in the tool.

​
Transcription engines

The chevron to the left of Transcribe opens three mutually exclusive engines:

PremiereGPT

Standard engine — fast and reliable. The default, and the right choice almost every time.

+ Advanced word precision

Re-syncs every word to the audio with forced alignment. Sharper timing, slightly slower, extra credits.

V2

The most accurate engine — and much more expensive. Only worth it when the standard engine genuinely isn’t good enough.
Pick by symptom: wrong words → V2 (or better AI Context first). Right words, drifting timing → advanced word precision. Anything else → standard.

​
Editing the transcript

The editor is the point of the tool. Everything below is instant and local — no re-transcription.
Fix recurring errors with Find & Replace before touching anything by hand — a misheard brand name usually appears a dozen times.

​
Translation

Pick a target language in the widget at the bottom right and click Translate. The translation is created as a new version: the arrows next to it let you move between versions, and the original is never lost.
Each version keeps its own timing, so you can generate an SRT per language from the same transcription without re-running it.

​
Importing an existing SRT

Import SRT loads an existing subtitle file as the working transcription. Use it to fix, re-time, translate or re-style subtitles that came from elsewhere, without paying for a transcription.

​
Common Pitfalls

  • Sequence longer than 2 hours → refused up front. Split it, or work sequence by sequence.
  • Language left on Auto with a multilingual take → mixed-up output. Set the dominant language and describe the mixing in AI Context.
  • Proper nouns wrong after a run → they belong in AI Context; re-transcribing without it changes nothing.
  • Music or loud background under the voice → transcription quality drops. Mute those tracks before running.
  • Editing after translating → each version is independent. Fix the source first, then translate.
  • AI Context over 800 characters is cut off. Keep it to the words that actually matter.
Recommended workflow: set the language → write ten lines of AI Context → standard engine → transcribe → Find & Replace the recurring errors → adjust Max Chars → Generate SRT.
