Kaltura MediaSpace and multimedia student guide

Lecturers also use MediaSpace to share multimedia content with you on Moodle.

To aid accessibility, videos on MediaSpace may have automated closed captions (subtitles) and a transcript. These may be switched on by default.

Advice on automated captions/transcripts

Currently our video content, delivered via Kaltura MediaSpace, uses closed captions and transcripts generated using automated speech recognition. This is about 70-85% (Kaltura, 2018) accurate depending on the topic, audio quality and lecturer.

We advise you not to rely solely on the captions/transcript when reviewing your video content.  These are considered a supplementary resource. Make sure you check the captions/transcript against the PowerPoint and readings to ensure you have a good understanding of the topic and the terminology used. You are encouraged to seek clarification from your teaching staff if necessary.

Closed captions appear as a text description on the right side of the video, which you can toggle on and off. Select Show transcript to display the transcript beside the video and select Hide transcript to hide it.

If you require accurate captions/transcripts as part of your reasonable adjustment, contact disability@city.ac.uk to discuss your requirements for quality captions/transcripts. This will then result in human intervention to make corrections on the automated captions/transcripts. This usually substantially improves the accuracy of the captions/transcripts, but the accuracy can still be impacted by terminology used, accent of the lecturer and audio quality of the recording.

Captions

To turn captions on and off, toggle the CC icon at the bottom of the video.

If the CC icon does not allow you to enable captions, access your settings by selecting the Cog icon directly next to the CC icon and choose your required language from the Captions dropdown menu. You will then be able to use the CC icon to toggle captions on and off.

Transcript

• Select the Show transcript icon in the top right corner of the video (a square half-filled with lines) to display the transcript on the right side of the video
  • Select Hide transcript to hide it again
• Enter a word from the video into the Search field to find that word in the transcript. You can then select the word from the transcript to jump to the relevant section of the recording.
• You can also print and download the transcript by selecting the ellipsis (three dots) next to the Search field.
