To meet accessibility guidelines, all videos provided to students must be captioned. There are a number of different ways to go about creating lecture videos, but there are some best practices for making the captioning process as simple as possible.

If possible, it is also best to create multiple short videos in place of one long lecture video. Research shows that student engagement when watching videos starts to decline after 6 minutes, but rapidly drops if the video is longer than 12 minutes.

Scripts

Creating a script prior to capturing a lecture is an incredibly easy way to make sure the captions for the video are completely accurate with little effort. If you prefer to talk through a topic instead of writing a script, you can use the Voice Typing function on the Tools menu in Google Docs. However, the MSU Google Apps does not have this function. You can either use the voice typing on document using a Google account or create the document with a Google account and then share it with your MSU account. The Voice Typing is a transcription service, so you can use punctuation by speaking specific phrases. After you have a first version of your lecture, you can edit the script for production.

Each lecture video should also stand on its own. Try to avoid discussing dates or assignments in the videos. Create separate videos for course-related communications. This way, if you change the course structure or assignments, you won’t need to remake the content videos.

Capturing

When you capture your lecture, you can either record the audio and video/slides at the same time, or capture them separately. Separately does require that you run through the lecture twice, but it minimizes the post-production editing that might be needed. To capture them separately, it is best to first record audio, reading through your script verbatim at a clear, slow pace, and then replay your audio while only capturing video. You can move through your slides at the appropriate time while listening to the script. Bring both the audio and video into your video software, and hopefully no editing will be needed. This process does require access to a video editing software like Camtasia, however.

Software

  • Camtasia - A screen capture and video editing software. Allows you to have full control of the post-production editing process. Can record separate audio and video and add them together during editing. Has captioning functions. Captioning is not very accurate, so editing is needed if a script wasn’t used. Not free.

  • CaptureSpace in MSU MediaSpace. Free add-on within MediaSpace. Has really great functions of using a PowerPoint presentation instead of a straight screen capture, allowing the video to use the slide text for searchability. Almost non-existent post-production editing capabilities. Must record audio with web cam/screen recording/presentation slides.

  • Jing - A free screen capture software from the makers of Camtasia. Has no editing capabilities, and limits videos to 5 min. The quality is also less impressive than the above two options.

Captions

Once you have your lecture video created, you will need to add captions.
