I got a text from a teacher to read and visualize. The video took about 3 hours to produce. First I read the text using the smartphone and handsfree as a microphone, inside a wardrobe 🙂 Then I imported the audio file into the video editing app Camtasia. Then I listened to the content and searched for relevant visual material, and most of the time I find it at https://pixabay.com. Animation of text and graphics as well as subtitling is also done directly in Camtasia.
