Going to YouTube

Videoshop and rush premium are a couple i use. The gopro apps i find frustrating to use.
I like videoshop, can stack up a bunch of photos for a slide show and edit int a video.
Start with videos less than 2 minutes, and dont clickbait the titles.
You can set it up as private, and invite your chosen viewers to watch. Get comfortable with what you do. The more videos,the easier it gets.
