Reviewing and editing video captions

This article explains how ReelFlow’s captioning system works, including automatic caption transcription, the caption review step, using our Caption Editor to make changes, setting the transcription language, and leveraging the dictionary feature.

Automatic video captioning

Captions are a critical part of the ReelFlow Player experience, ensuring accessibility, SEO/AEO optimization, and viewer convenience.

ReelFlow automatically generates captions for all videos added to the Library, and provides editing and a custom dictionary for auto-correction of terms (e.g. your organization name). This guide covers how to generate, review and edit captions, and publish Flows with the confidence.

  • Captions are automatically generated when you upload a video to the Library.
  • Captions are created in the Workspace’s default Caption Transcription language, which can be modified in the Workspace Settings. 
  • Automated text substitutions based on your custom dictionary (e.g., names, company terms) are highlighted in the editor for easy review.
  • A Flow cannot be published until all captions in that Flow have been approved by you. If a video reel in Flow hasn’t been reviewed for accuracy in the Caption Editor, a pre-flight check will pause publishing and warn you that will need to review and approve the captions to continue with publishing.

Using the Caption Editor

Making changes to and approving captions

  • You can open the Caption Editor from these two locations in the Dashboard:

    • the Library - select a video to open the flyover, then choose Edit from the Captions section 
    • in the Flow Builder - from the Step Settings flyover
  • Captions are divided-up into “units” and each represents how and when they appear   website visitors during video playback.
  • Each caption "unit" in the editor represents a period of time. We will outline the unit with a red line if your modification to the caption text might make it too long to display, or too short for the time allocated.
  • You can revert any changes you’ve made to a caption - right click on the unit, and select revert to original text from the menu. Alternatively use the undo/redo controls.
  • Captions must be reviewed and marked as Approved before you can publish successfully. Select the Approve button in the Caption Editor to complete this step.

Using the Dictionary

  • Your Workspace has a custom Dictionary of phrases which is used when captions are generated, and provides a way to preserve custom terms and brand names you commonly use in videos, such as the spelling of your organization name.

  • Items you save to the dictionary will influence future caption generation, ideal for saving brand names or uncommon terms that you may otherwise need to spell out

  • Words and phrases in your Workspace Dictionary will be underlined in the captions shown in the Caption Editor

Adding and removing words and phrases to the Dictionary

  1. In the Caption Editor, select the word or phrase then right-click

  2. Select from the options to:

    • Add the selected word or phrase as a new substitution to the dictionary
    • Remove a word from the dictionary to stop it being substituted in future transcriptions.

    • Revert to the original word if a substitution has been made

Changing the video Caption Transcription language

  • Choose the language when you upload a video from the upload flyover.

  • Videos captions are transcribed (or translated) into English by default, however, they can be transcribed from or translated into many languages including: Afrikaans, Arabic, Armenian, Azerbaijani, Belarusian, Bosnian, Bulgarian, Catalan, Chinese, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, Galician, German, Greek, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Italian, Japanese, Kannada, Kazakh, Korean, Latvian, Lithuanian, Macedonian, Malay, Marathi, Maori, Nepali, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swahili, Swedish, Tagalog, Tamil, Thai, Turkish, Ukrainian, Urdu, Vietnamese, and Welsh.

  • Whichever language you set on your most recent upload will become your preferred language, and used for future transcriptions until changed.

  • If the language you set matches what’s spoken in the uploaded video, we transcribe. If it doesn’t, we will attempt to translate it.

  • To use a change the caption language for a video already in your Library, you will either need to use the Caption Editor in the Library and do so manually, or alternatively re-upload the video to process it again, this time selecting the correct language.
