Simple video editing program with color grading?

I'm just looking for a free editing program, with which I would like to cut my GoPro films. It should be pretty easy, since I do not really have experience in the field. In addition, another problem may be that I want to cut with my laptop (i5 8250u and uhd620) and as I understand it, they fall into this category, for example. DaVinci Resolve and Hitfilm Express are gone because they just need more power. Important for me is definitely that you can insert your own music and Color Grading would be great. Maybe someone has an alternative.

PS: And timeline is very important.

DaVinci Resolve is the right program for you, even with your i5 8250u.

To be able to work on UHD, you have to work with proxy files ("optimized media") anyway, but you will not be able to do that without exact knowledge, so you only have to learn until you can use the program correctly.

Have lots of fun with it.

I5 is already a little close to the program, if you really have later 4K Cut to 60 fps ze you already have to convert.

I myself have a Macbook Pro with:
2.9GHz Intel Core i9
32 GB 2400 MHz DDR4
Radeon Pro 560X 4096MB / Intel UHD Graphics 630 1536MB

Best video editing program as well as Color Grading is Final Cut Pro only for MacUser
