We have added closed captioning support for on-demand and simulive events. To explore the capabilities, follow these steps:
- Go to your venue’s Media Library
- Upload a video. After the video is uploaded, you will see a “Processing” label on the video. Wait till the video has completed this processing.
- Select the video. You will see its properties listed in the right hand side column. Towards the bottom, you’ll see a Closed Caption heading with two sub-menus: Generate and Upload.
Auto-generate Closed Captions
Generate is a machine translation service that automatically generates a CC file for the video in several supported languages. To explore, click on Generate, select your target language and let the engine run. Within a few minutes, you will see a file listed with that language heading. That’s the translated CC in that language. You can generate CCs in multiple languages for the video.
Our supported CC file format is WebVTT with the extension of .vtt. VTT files are text readable files and editable by any text editor.
Upload Closed Captions
The quality of the auto generated CC files will vary greatly based on the quality of the video audio, speakers’ accents and the technical nature of the conversation in the video. In general, the auto-generated files are good starting points but will require human review and refinements. The text in these files can easily be edited and saved. You can then “Upload” these files under their corresponding language heading. Uploaded files will overwrite existing CC files.
You can have closed captioning automatically on or off as a user enters a session. Control this setting for all of your sessions from the Administrative menu’s Session page. Click on the Default Settings link.
Video Localization: Burned-in Subtitles or Closed Caption
When localizing videos, short of translating the audio, you have two options: burn-in the subtitles into the video, essentially generating a new localized video or use CC in the target language. The latter is an extremely effective way of localizing, while allowing you to maintain a single version of video in its original audio with no burned in text.
At Engagez (www.engagez.com), we strive to offer the best capabilities for hosting the most effective live, simulive (simulated live) and on-demand online events and instructor-led online classes.
