A cool guide software alternative

It depends on the use cases. I don't like how this post makes it look like the "Linux" alternatives are drop in, one-to-one replacement. Inkscape has been immensely useful to me, but for professional work, it might not be a reasonable replacement.

DaVinci Resolve is not exactly free but the affordable paid version is better than premiere in the eyes of many industry pros. It's pretty unique in how it gives you a full post-production package in one software so you can seamlessly progress through the various parts of the project. The colour page has long been the top dog in that space and the rest is definitely serviceable though since I don't use that heavily I can't really confirm if fusion holds up against after effects, maybe you can combine that with blender and the other tool listed here as AE alternative.
