Here’s a great beginner-friendly video that directly demonstrates basic ATEM Mini Pro operations like switching inputs and muting audio—perfect for volunteers working with an already-configured setup:

ATEM MINI 101 Beginner’s Guide (Switching & Audio Basics)

📽️ Why This Video is Ideal:

• Introduces the front-panel layout, including Input 1–4, Cut/Auto, and ON AIR buttons

• Demonstrates live switching between camera feeds—learning which button does what

• Shows how to manage audio levels and mute/unmute microphones, straight from hardware and software

• Ideal for systems that are already connected and just need operational guidance

🔧 Additional Tips on Audio Setup:

• Set each mic input to Line or Mic level as needed (forum.blackmagicdesign.com, reddit.com)

1. Watch the video together and pause to practice switching inputs on your own ATEM unit

2. Try muting and unmuting mic inputs during the demo

3. Follow up with a hands-on mini-training session with real service audio and camera feeds
