Troubleshooting Missing VTT&CC Overlays - Curator Playback

Steps

1. Validate that your subtitles are not displayed properly or not displayed at all in Curator playback by navigating to Curator Clip Link & Clip Select or Curator Logger.
   
   
   
2. Make sure that you have enabled them via the CC button below the middle section of the video.
   
   
   
3. Validate that you have included the .vtt extension in IIS MIME TYPES:
   1. Open Windows IIS by searching for it in taskbar
      
      
      
   2. Click on the Default Web Site in IIS.
      
      
   3. Select MIME TYPES
      
      
   4. Scroll down and try to locate the following extension:      
   5. If the extension is missing, add it by clicking on Add.
      
      
      
   6. Enter the following in the 2 fields. File Name Extension: .vtt       MIME Type:  text/vtt
      
      
   7. Navigate back to the Default Website & restart it. 
      
      
4. Make sure that the actual .vtt file exists in the WebProxy location & that it contains the expected values.
   1. Navigate to your Proxy destination within the IIS Proxy folder and open it.
      For example in this instance, the proxy & .vtt subtitles are located within:
      C:\CuratorStorage\Curator\TEST\Proxies\WebProxy\2022\02\23\CC2-150719
      
      
      
   2. Validate that the example_subtitle.vtt (CC2-150719_subtitle.vtt in our instance) file exists.
      
      
   3. Open the example_subtitle.vtt (CC2-150719_subtitle.vtt in our instance) & make sure it has the expected values within it
      
      
   4. In this instance, the subtitles will not work as the example_subtitle.vtt (CC2-150719_subtitle.vtt in our instance) is empty as shown in the screenshot.
      
                  For example, a .VTT file should look like the one below as opposed to being completely empty:
      
      
      
5. Check if the web.config file for the affected web application (Clip Link/Select/Logger or all etc.) has the correct values specified.
   1. Open IIS via your Windows taskbar.
      
      
   2. Click on the default website & expand it.
      
      
      
   3. Right-click the affected web application & click Explore.
      
      
   4. Right-click the web.config file & open it.
      
      
      
   5. Scroll down to the subtitles section.
      
      
   6. Make sure it has the correct values that are shown in the screenshot
      <add key="SidecarTextTrack[0].src" value="_subtitle.vtt" />
      <add key="SidecarTextTrack[1].src" value="_subtitle_en.vtt" />
      <add key="SidecarTextTrack[2].src" value="_subtitle_fr.vtt" />
      <add key="SidecarTextTrack[3].src" value="_subtitle_de.vtt" />
      <add key="SidecarTextTrack[4].src" value="_subtitle_es.vtt" />
      Save Changes.
      
      
   7. Navigate back to IIS & restart the Default Web Site.
