Overview of Options for Skyline Video Captioning

Page Topics

 

A longer process (but still works!) 

 

If you plan to caption your video on your own instead of leveraging California Community College resources such as 3C Media Solutions, the following applications may be of use:

Otter.ai
This web-based platform can auto-generate editable transcripts from a recording. If provided with clear sound quality, Otter.ai can accurately convert speech into text as well as add punctuation. A Free version offers 10 hours per month of speech conversion while the Paid version provides longer recording times, the option to export .SRT caption files, and other features. There is an education discount available if using your .edu email address.
YouTube
A web-based video platform with multiple captioning features, such as creating auto-generated caption files from video content and synchronizing text files with videos.

"What is the best way to embed a video on a Canvas page?" 

For mobile users, videos that are embedded using Canvas' Media Comment Tool, 3C Media LTI, or any LTI installed in the Rich Content Editor (for example any video streaming libraries such as Kanopy, Films on Demand, or YouTube) look best and remove ads (seen commonly in YouTube embeds.)

 

Method 1: YouTube Captioning

First, register for a free YouTube account or use an existing GMAIL account. Note: Some faculty prefer to use a dedicated professional YouTube account that is separate from a personal GMAIL account. 

Captioning Quick Tips

When you upload a video, immediately set the language to English (or the video's native language). It may take a couple of minutes to 72 hours before auto-generated closed captioning appears. 

  • When you edit the auto-generated caption track, this creates a new track called "English". When you have completed the edits, delete the old "auto-generated" captions. By default, YouTube will play the unedited auto-generated captioning track and you want the corrected version to play instead.
  • Set closed captions to immediately appear upon playing the video.  

Leverage Auto-Generated Captioning 

Watch Michelle Clark's video introducing editing closed captioning from auto-generated captioning. 

Have a Transcript? Lucky you! 

Having a transcript (preferably in digital form) can save a ton of time. Transcribe away!

Use YouTube'sTranscribe and auto-sync feature to sync your transcript to your uploaded video. YouTube will try to synchronize the transcript you created to the video's audio. It may take a couple of minutes to 72 hours to produce your final video.

You will need to review to make sure that captions are accurate and in sync. Remember to add-in sound effects or any other non-textual sounds (e.g., [background music], etc.) as part of your transcript so that it makes it into YouTube's caption track.

Watch the following video, Automatic Timing For Captions, to learn how to use the script (now a transcript!) you created, and upload it into YouTube to turn the transcript into captioning. To read the instructions instead, visit Medium.com's Video Captioning: YouTube Transcribe and Auto-Sync as a Workflow Tool.

No transcript, no caption file?

No problem. You can leverage YouTube's Auto-Generated captions. 

While YouTube's auto-generated captions are not sufficient on their own, they can be a starting point for you to edit and correct if you do not have a transcript. Auto-generated captions may take a couple of minutes to 72 hours to appear after uploading a video to YouTube. Various other factors -- such as video length, file size, or YouTube experiencing lag -- can affect the processing time.

  1. If automatic captions are available, they'll automatically publish on the video under Video subtitles in your YouTube account.
  2. Learn how to review, edit, or unpublish automatic captions by placing your cursor over the Published Automatic section to force the Options button to appear (three dots). 

Manually Create Captions 

Captions can be manually added to a video. See YouTube's tutorial, Create Subtitles or Closed Captions. Please note, depending on captioning skills, a 5-minute video may take at least 30 minutes to produce a final video draft with accurate captioning. For this reason, starting with a transcript can streamline the captioning process.

 

Obtain caption file using YouTube

 

Once YouTube has generated captions, edit as needed for accuracy. To download your clean caption file:

  1. Visit your YouTube Studio.
  2. On the left-hand side, select Videos
  3. On the left-hand side, select Subtitles.
  4. On your desired video, select the three-dotted icon, the Options button. Then select Edit on Classic Studio to obtain the accepted caption file type to use in Canvas.
  5. In the View published subtitles and CC: English window select Actions. Download either .srt or .vtt file (accepted Canvas caption file formats).

 

 

Method 2: Otter.ai to generate transcript and YouTube Transcribe & Auto-Sync 

 

This is a more involved process requiring different applications and tools.

To learn about using Otter.ai and YouTube to create a caption file, please register for the free, self-paced course Video Captioning to learn about how to integrate Otter.ai into your captioning workflow.
