What are some good editing apps to make band edits? For iPhone?

I like to make video edits for my favorite bands like Fall Out Boy, Panic! At the Disco, bands like that. I wanna make edits on my iPhone but don't know any good apps to use. Also, how can I use gifs to make edits?

Animated gifs are fine for certain things. I would avoid using GIFs for photography as the color quality is too low.

I don't use my smartphone as a camera, I have a camera when I need a camera. You can do post processing with GIMP, which is a great free app from gimp.org. It's only available for a desktop computer. For the phone, I would go with Adobe Lightroom Mobile.
