Screencasting Guidelines:
Captions

This LibGuide outlines the best practices that must be followed when creating a screencast as part of the University of Waterloo Library.

Accessibilty and government standards

The Information & Communications Standard, under the Accessibility for Ontarians with Disabilities Act, includes web accessibility requirements. The University has committed to meet all WCAG* 2.0 Level A requirements, and meet the Level AA requirements where feasible.

For Level A compliance, captions are to be provided for all pre-recorded audio-visual content. Therefore, all screencasts hosted on the Library website or Library channels are to be captioned.

*WCAG is the acronym for Web Content Accessibility Guidelines. More information is available at http://www.w3.org/TR/WCAG20/

Captioning

Use closed captioning (CC), for it enables viewers the choice to view with or without captions.

Note: Captions take up approximately 25% of the lower section on your screen, therefore plan accordingly.

  • Click on the Captions tab. If its not in view, click the More tab. From the list, select Captions.




  • Make sure the On Video button is enabled. This will overlay the captioning onto the video.





  • Click Add Caption button. A caption point appears in the pane next to the text box.





  • Paste in your narration text right inside the captions box. The caption appears in the preview window as your type.

    Tip: Break sentences into two lines where you would normally find a pause in speech



    Note: Captions beyond three lines long change to red. The red text indicates where a new caption point should begin.  To include the red text, insert the text cursor before the first red word and click Add New.






  • Synch it with the audio and manually edit when necessary. This is done in the same manner as editing the length of time a call out is displayed.

Exporting Captions

To export the .srt file click the Export captions button at the bottom of the captions window.  Camtasia will prompt you to name and select a save location of the file.

When you have published the video, email the .srt file along with the video to the designated staff member responsible for the YouTube account. They will upload both files which will allow for Closed Captioning to turned on and off.
