Where it starts
A syllabus before a single lesson
The hardest part of a course is not recording it. It is deciding what goes in it, in what order, so that lesson six does not need something lesson nine has not taught yet.
Describe the subject, who it is for and what they should be able to do at the end, and you get modules and lessons in teaching order, each with a brief. Every title and every lesson is editable before anything is made, so you are correcting a plan rather than staring at an empty page.
You can also build the course from your OWN material: paste your research, notes or a transcript, or point it at a page. Each lesson is then written from the part of that material it actually covers, not from the first two pages.
And if you already have footage, use it. A long screen recording is split into lesson-sized segments, each one transcribed, so the narration talks about what is actually on screen. Some tools need a recording before they can do anything at all; here it is one option among several, not the price of entry.
How Chitrio does this: Planning a course costs nothing. Nothing is charged until you render a lesson, so you can throw away three syllabuses before you like one.
