The following video guide provides a great introduction to accessible multimedia. Also, note that Wake Tech eLearning Support has created several video tutorials for making documents and multimedia accessible, which you can access by viewing their playlist in YouTube.
For course materials that have audio narration, such as podcasts or narrated PowerPoint, transcriptions need be included. Creating a script for your audio presentation will allow you to have the text ready to include in transcript format. However, if you prefer to record first, you will need to take the time to transcribe what you have recorded after the fact. While this may seem like a lot of work, keep in mind that a transcription may be helpful to various students, such as those with English as a second-language (ESL) or those who prefer written over audible content. It is possible that your college offers resources for transcription, particularly if you have a student that is hearing impaired in your course. Additionally, there are many online services that will quickly create a transcript of your audio files for a fee; however, the costs will vary depending on the length of your file.
Videos should include closed captions whenever possible. Transcriptions are an acceptable alternative, however, the synchronicity of captions is often beneficial to English as a Second Language (ESL) students as well as hearing-impaired students. Transcripts can also be easily searched to find specific content topics. If you have a transcription created, you can use YouTube's captioning tool to quickly and easily create captions.
Depending on how your videos are hosted in your course (meaning where the video is stored and accessed from) there may be a specific tool that you can use to create captions. The office that manages the Learning Management System (Canvas, Blackboard, or other) will be able to provide you additional information on how videos are created and shared in your system.
The same considerations that you will need to apply for creating accessible documents will also apply to any multimedia. Please review the other pages in this "Accessibility" section for more information.
