Why teacher welcome messages suits AI video

A friendly face at the start of a course makes it feel human. A talking photo is short, so it suits a greeting, not a lesson, and it can sit at the top of a course page.

What to put in your photo

  • A clear headshot, facing the camera
  • A relaxed expression and even light
  • A plain background

An example you can adapt

Example photo: A headshot of a teacher with glasses, smiling, facing the camera.

Example voiceover: "Welcome to class! I'm so glad you're here. Let's get started." That script is 11 words, so the talking photo runs 8 seconds and costs 2 credits in Full HD or 4 credits in 4K.

Sound and camera

  • Subtle head movement feels warm
  • Choose a voice that suits the age group
  • Horizontal 16:9 for a course page

Mistakes to avoid

  • Using a student's photo without permission
  • Trying to teach in 8 seconds: save the lesson for your own video
