I've been assembling and editing video for a couple decades now. For what you're doing, the quality is great! I really like the post-cleanup images of what you dug. Was this a cap-clapped camera? If I do videos in the future, I plan on wearing an on-glasses POV camera so I have better control over camera framing.
Two questions though:
1) How do you like those Ironclad gloves? Do they last?
2) How did you not scratch that coin? Wow.
