As an Atlassian University Trainer, I delivered, recorded, and edited the JIRA Essentials, JIRA Agile, and Getting More from JIRA Workflows Atlassian University courses. Atlassian sold these videos as on-demand training as part of their Atlassian University (AU) portfolio.
I used Camtasia to record and edit screen capture of slides, live demos, and audio. Each AU course had 10-25 modules to record.
Beyond recording, I also managed another instructor who recorded, edited, and delivered an additional three courses.
