Audio-visual materials in the learning process

• You can host them as private videos on YouTube or Vimeo, where only users with a link can view them. 

• Store the video files in Dropbox (or any other cloud service) and share the link with the people who need it.

• Share the link on your learning platform, website or simply send it to students.

• If you need to make only a couple screencasts, it might not be worth the time it takes to set up and learn how to use a screencasting tool.

• Making a screencast can take a lot of time, if it requires editing or other enhancements, — that could take a couple hours to do. However, the benefits of a video material will be greater than the initial efforts.

•  Will the screencast save you some time later on? For example, will it mean that you don’t need to explain something many times to many people? 

The best answer could be to create your own training video library and make sure these materials are useful for themselves.
