Why Are Captions Important?
Captions are a required accommodation to allow the learning content in your video to be accessible to students who may be d/Deaf, hard-of-hearing, or are learning with another disability. Additionally, captions have been proven to help all students with comprehension, memory, and retained attention while watching videos (Gernsbacher, Morton 2015). If a student is learning on a mobile device or in a public place, captions can help accommodate their experiences if they can’t play audio out loud.
Before You Begin
PlayPosit does not create captions for you, it allows you to upload existing caption tracks. If your video is self-recorded, you will need to have a .srt or .vtt file to upload to PlayPosit.
If your video is already recorded and you need a caption track, learn how to create captions with Adobe Premiere Pro. If you typically create your videos in Zoom and have not yet recorded the video for your PlayPosit Bulb, learn how automatically transcribe recordings in Zoom before you start recording.
If the video linked to PlayPosit is from YouTube or Vimeo, you can easily connect the existing YouTube or Vimeo captions to PlayPosit.
