Hello!
Firstly, I'd like to say 4 viral video would be a really tricky project, but I believe I may have 1 video which could go viral. It is a drone cinematic video that was filmed in New Zealand and America in 2016. Based on your YouTube page title, A Fascinating World, I think this may interest you a lot!
If you would like to discuss this matter and maybe you could potentially buy this video off me?
Best,
Luke Baillie
