As mentioned at the beginning of this module, many people go to video-sharing sites like YouTube to find tutorials. An instructional video is any video that demonstrates a process, transfers knowledge, explains a concept, or shows someone how to do something. Most people are visual learners and like to see how things are done.
You can easily create a video from your finished tutorial. The steps you have written out can become your script. If you have saved high-quality versions of your images, you can incorporate them into a video. Or you can create a screenshot video, narrating it with the steps from your tutorial.
