How to produce YouTube videos simpler?

Today I published my first youtube video. It was much harder to make than I expected.

I learned a lot:

• Lightning
• Sound setup
• Screen + Face + Drone recording
• Kdenlive
• OBS recording settings
• public domain licenses
• time wrap
• cutting, effects, ...
• publishing at youtube

I invested over 15 hours in producing 16 minutes video.

Is this huge time effort normal?
How do you prepare your videos?
How do you edit them?
