SOL allows you to easily share video from across the internet, and present it in several different ways.
There are various services, most notably YouTube and Vimeo, which allow you to upload and store video that you have made, for free.
Top tip: Look at Library video resources such as Box of Broadcasts (BoB) to embed into your unit. Or as a way of sharing your videos on SOL, look into Lecture Capture. Contact email@example.com for more details.
Remember: You should only use content that you have the rights to use. If you are unclear on what this includes, go to Copyright matters, Media Resources on the Portal.
