Video editing

Video caption editing

Captions turn speech into text on screen. They let people who are deaf or hard of hearing follow a video, help viewers watching without sound and make content easier to search. Automatic captions are a quick start, but they make mistakes with names, terms, accents and overlapping speech. Caption editing means checking and correcting every line, timing it so it appears with the speech, breaking it into readable lines and choosing whether captions are closed, so viewers can turn them on and off, or burned into the picture.

This page covers accuracy, closed and burned-in captions, line length and timing, styling, speaker labels and automatic captions.

Anatomy of good captions. Accurate, timed, readable.

Why accuracy matters

A caption that gets a product name, a price or a person's name wrong can mislead or embarrass. For viewers who rely on captions, errors mean missing part of the message. Checking every line against the audio, especially specialist terms and names, is the core of caption editing.

Closed and burned-in captions

Automatic captions as a start

Platforms and editing tools can generate captions using speech recognition. YouTube's help explains that its automatic captions are created this way and are only in the video's default language. They save time but need checking. Errors are more likely with background noise, accents, technical vocabulary and people talking over each other.

Line length and timing

Captions should appear as the words are spoken and stay on screen long enough to read. Break text into short lines at natural pauses, avoid splitting names or phrases across lines and keep to one or two lines at a time. Long blocks of text are hard to read, especially on phones.

Editing captions

  1. Generate or transcribe

    Automatic captions or a transcript.

    Output: Draft text

  2. Check

    Every line against the audio.

    Output: Corrected text

  3. Time

    Sync to the speech.

    Output: Timed captions

  4. Break lines

    Short, natural lines.

    Output: Readable captions

  5. Export

    Caption file or burned-in video.

    Output: Final captions

Example: captions for a medical supplies company

Illustrative example — not a client case study

Situation: A medical supplies company's training videos use automatic captions that misspell product names.

  1. A list of product names and terms is supplied to the editor.
  2. Every caption line is checked and corrected against the audio.
  3. Closed caption files are supplied for the website and burned-in captions for social clips.

What this shows: Captions became accurate and consistent across videos. This example is illustrative.

Before publishing

Accuracy

  • Names and terms correct
  • Numbers and prices correct

Readability

  • One or two lines at a time
  • On screen long enough to read

Placement

  • Clear of interface areas
  • Good contrast

Styling burned-in captions

Burned-in captions should be large enough to read on a phone, high in contrast, in a clear font and placed where platform buttons and labels will not cover them. A consistent style across your videos looks professional. Test the style on a light and a dark background.

Speaker labels and sounds

Where several people speak, labels or placement can show who is talking. Captions intended for viewers who are deaf or hard of hearing may also describe important sounds, such as music or laughter, in brackets.

Other languages

Captions in other languages are translation, not just transcription, and should be done by someone fluent in both languages. Check how each platform handles multiple caption tracks. Start with the languages your viewers actually use.

Transcripts

A full transcript, placed near a video on your website, helps people who prefer reading and can be searched. It can be produced from the checked captions with light editing for readability.

Consistent spelling and style

Keep a short list of names, product terms and preferred spellings, so captions are consistent across every video. Decide how numbers, units and abbreviations are written, and apply the same rules each time.

Recording for better captions

Clear speech recorded close to a microphone, with little background noise or music, gives automatic tools a better starting point and makes checking quicker. Asking speakers to avoid talking over each other helps too.
