Creating Captions

Learn how captions are created and accessed in Scriptix.

How Captions are Generated​

Captions in Scriptix are automatically generated from your uploaded audio or video files during the transcription process. When you upload media to a session, Scriptix:

  1. Transcribes the audio to text
  2. Generates time-synchronized caption segments
  3. Creates caption documents that can be edited and exported

Accessing the Caption Editor​

From Your Workspace​

  1. Navigate to your Workspace
  2. Find the session containing your captions
  3. Click on the caption document to open
  4. Caption Editor opens automatically

The caption editor is the interface where you edit caption text, adjust timing, and export in various formats.

Once the caption editor opens, you can:

Edit Content:

  • Edit caption text directly in each segment
  • Fix transcription errors
  • Improve readability
  • Add or remove text

Adjust Timing:

  • Modify start and stop times for each segment
  • Use timing shift control for bulk adjustments
  • Ensure captions sync with speech

Search & Navigate:

  • Search for specific text across all segments
  • Filter segments by search query
  • Jump to specific segments

Export:

  • Download captions in multiple formats (SRT, VTT, SBV, TTML, STL, HTML)
  • Include or exclude speakers
  • Include or exclude timestamps (where applicable)

Share:

Caption Document Structure​

Each caption document contains:

Segments:

  • Individual caption entries with start/stop times
  • Text content for each segment
  • Speaker information (if applicable)

Timing Information:

  • Start time (HH:MM:SS.mmm format)
  • Stop time (HH:MM:SS.mmm format)
  • Duration (automatically calculated)

Metadata:

  • Session information
  • Language
  • Creation date
  • Filename

Caption Editing Workflow​

Typical workflow for caption editing:

  1. Open caption editor from your workspace session
  2. Review the auto-generated caption segments
  3. Edit text to fix any transcription errors
  4. Adjust timing if captions don't sync with speech
  5. Use search to find and fix specific issues
  6. Export in your desired format (SRT, VTT, etc.)

Auto-Save​

The caption editor includes auto-save functionality:

  • Saves every 2 minutes automatically
  • Saves to localStorage as backup
  • Syncs to server for permanent storage
  • Undo/redo preserved (20-level history)
  • Save status shown in toolbar (synced, saving, saved-locally, unsaved)

Export Formats​

Caption documents can be exported in industry-standard formats:

  • SRT (SubRip) - Most widely compatible
  • VTT (WebVTT) - HTML5 web video
  • SBV - YouTube subtitle format
  • TTML - Timed Text Markup Language
  • STL - EBU broadcast standard
