Extraction of subtitles from video files using watchfolders

FAB Subtitler PRO/LIVE/MPEG can be configured to monitor folders and extract teletext subtitles from MXF video files as soon as a video file is present in the folder. All subtitles (texts and timecodes) from the video file will be saved to a subtitle file into the output folder.

To configure this type of automatic operation:

  1. In Options/Special/Automation configure the following:

  1. Save a file with the name “watchfolder.xml” which contains the correct settings to the input folder:
<?xml version="1.0" encoding="utf-8"?>
<fab-automation>
  <operation>
    <type>subtitleExtraction</type>
    <sourceFile></sourceFile>
    <targetFile></targetFile>
    <configFile></configFile>
    <deleteFiles></deleteFiles>
    <subtitles>
      <subtitle>
        <filename>*-778.stl</filename>
        <language>eng</language>
        <ttxpage>778</ttxpage>
        <typeFormat>1</typeFormat>
        <range>
          <from>1</from>
          <to>last</to>
        </range>
      </subtitle>
      <subtitle>
        <filename>*-777.stl</filename>
        <language>ita</language>
        <ttxpage>777</ttxpage>
        <typeFormat>1</typeFormat>
        <range>
          <from>1</from>
          <to>last</to>
        </range>
      </subtitle>
    </subtitles>
  </operation>
</fab-automation>
  • The automatic conversion operation will start when the file “watchfolder.xml” and the MXF video file to be processed both exist in the input folder
  1. To activate the automatic operation click on Extras / Tools > Start automatic mode

  1. To run FAB Subtitler in automatic mode in a 24/7 operation it is recommended to start FAB Subtitler using FAB Activity Manager. FAB Activity Manager will:
  • Start FAB Subtitler
  • Continuously check if FAB Subtitler is running correctly
  • Restart FAB Subtitler if any problems are detected
