Many good teachers never record a course because they don't want to be on camera, or don't have the time to film, light and edit. A narrated video made from a script works just as well for most lessons. Students hear a clear voice, see one picture per idea and read the words as they are spoken.
This is how to do it so the whole course feels like one course, not a pile of separate videos.
1. One lesson, one video, one outcome
Before writing, finish this sentence for each video: "After this video, the student can ..." If you need "and" twice, it is two videos. Short lessons of 3 to 8 minutes are easier to watch, easier to update, and easier to find again when a student needs to review.
2. Write the script to teach
- Start with why it matters, in one or two sentences.
- Explain one step at a time, in the order the student will do it.
- Give one worked example with real numbers or a real case.
- End with a short recap of the outcome, in the same words as the start.
Write the way you would say it to one student across a table. Short sentences. Say numbers the way people say them.
3. Choose one calm look for the whole course
Write down the look once and keep it: the colours, the kind of picture, how text appears on screen. Use the same voice for every lesson. Leave out things that suit YouTube but not a classroom, such as "subscribe" cards and fast cuts. Use wide 16:9 videos, which every learning platform plays well.
Plan for updates: keep each lesson's script and pictures in its own folder. When a rule or a price changes, you remake one lesson, not the course.
4. One picture per idea
A picture should change when the idea changes, not on a timer. A diagram for a process, a simple scene for an example, a large number for a key figure. If the same idea comes back later in the lesson, show the same picture again: repetition helps students remember.
5. Captions and accessibility
Word-by-word captions help students who are watching without sound, learning in a second language, or taking notes. Read every caption once: names, terms and numbers are where speech recognition goes wrong. Many schools and companies require captions, so treat them as part of the lesson, not an extra.
6. Check it like a student would
Watch each lesson once at normal speed, start to finish, with the script closed. Could a student follow it without you there? Check every fact and figure against its source, and make sure you have the right to use every picture and piece of music.
Where vbe | video build engine fits
vbe is a Mac app being built for exactly this: paste a lesson script, keep one look saved for the whole course, see the cost of each paid step before it runs, and render wide videos on your Mac with captions on every word. See how it works.
