You can create caption files using web-based tools and software like Camtasia Studio and YouTube. These options are low-cost, but are time intensive and require a medium-level of technical expertise to use. We would recommend using this option only if you have staff or student employees available to correct the inaccuracies of the captions manually.

Machine captions are available at no cost for all media stored in MediaSpace. Once your content is available in MediaSpace, you can order machine captions and edit any inaccuracies using the steps below:

Editing Machine Captions in MediaSpace

The accuracy of machine captions is dependant on the quality of the recording and the speaker’s voice. Typically, the accuracy of machine captions in MediaSpace will be about 70-80%, so we strongly recommend that you correct the inaccuracies of the captions manually, which can be done through the captions editor in MediaSpace.

To edit a caption, go to the video file that you would like to correct and click “Actions,” then “Edit Captions”

Highlight of Edit Captions option in the Actions menu.

Note: You can only edit captions if your captions have been already been processed. Look for “Complete” under status to see if they have been processed. If you see “Complete,” you can click on the word and it will take you to the captioning editor.

Deleting Machine Captions in MediaSpace

There are some instances where you may want to delete caption or transcript files from your MediaSpace content. For example, if you ordered Machine Captions (which require editing for accuracy) then later decide that you would like to replace them with 99% accurate captions provided by a vendor, you will want to delete the less accurate machine captions. This will avoid confusion for your viewers about which captions and transcripts that you would like them to view.

These instructions will help you delete caption and transcript files from your MediaSpace content. Note that video owners are the only users who can delete caption or transcript files.
