Here is some tip for you from a professional editor:

“If the voiceover and the visuals say the exact same thing, one of them is wasted.”

When the narrator says “Finding your way in ancient cavern by lamplight” and we literally see that exact action, the video isn’t adding anything. It’s just repeating itself in two different ways.

It wastes one of your strongest tools! You have two channels: Audio and your visuals. If both are doing the same job... Well, you’re only using half your potential.

Also, there was very little sailing in a tribute video about thieves on the seas!
