Hi there,
I would love to help you with editing GoPro Hero Black 7 video files!
There is no easy way to learn and edit videos in a short time, so I suggest you to upload files and share them with professional person in that field!
If you choose to work with me, I will guide you where and how to upload files, also I can edit them, can do color grading, audio editing and other improvements!
Feel free to contact me over chat so we can discuss more about details.
Regards
Bogdan
